@@D3Sshooter loved the tutorial need some clarification on the fan velocity I have a fan that is 5400 m/h what would it be in a cross draft booth 3m x 2.4m x (.3 - .6) ? Not sure if I understand or not thanks.
Just finished your full series plus the extra follow up video, thank you so much. I’m planning more of a temporary booth, but learned a lot of ideas from your project. You have done the best job on all of RUclips explains things, and demonstrating how they work, such as your smoke and light examples. You are a great teacher. I will check out more from you, you have a ton of content I’m interested in. If I just had more time to watch them all!!!
Excellent series which has helped me tremendously! Clear common sense advise and very well filmed/edited, also the airflow rate advise was perfect.Your like a human Swiss army knife....you do everything! Thanks
We have recently installed a spray booth in a Sprinter van for Alloy wheel refurbishment. This worked well at first, but we have run into clearing problems that need to be addressed. Your brilliant explanations of spray booth design and calculations will be used to fix the problem. Thanks for your excellent video.
Maths is wrong, multiplying by 0.6 as opposed to 0.3 you would required a fan to move 18000 cu mtrs/hrs, so you are olny going to be able to move airflow at 0.15 approx with your 4000 cu mtrs /hr fan!
Great video Steve as always, thank you. Can you check your calculations though: you give, Flow Rate = Width x Height x Air Speed x Time which transposed gives, Air Speed = Flow Rate / Width x Height x Time. For 4000m3 Flow Rate this gives an air speed of just 0.128 m/sec not 0.7m/sec. Unless I have missed something fundamental, in which case I apologise.
Thanks for the erratum Steve. I am in the process of building my own booth and your video series has been invaluable. I just needed to ensure I had the right calculations. This video series has been very helpful and I am also very envious of your Truck! If only I could find something like that here in the UK. Cheers
@@David-lg5gi Can you possible assist, as I watched the video and thought the calculations were off somewhat. I am making a small booth for spray painting furniture and use water based paints and it will be 2.3m height x 2.3m width (also the depth is the same 2.3m) can you estimate a fan size and air flow rate. Apprecate any help!
Just came across a calculator and believe this is correct, 2.3m h x 2.3m w/ Floor area 5.29m2/ Ciling height 2.3m/ Volume 12.167m3/ ACH 20/ Required Airflow 143.22 CFM/ Airflow rate 0.0676 m3/s (8.593ft/h/ 243.34m3/h so a fan equivalent to the m3/h would be suitable. 👍
TXS for the comments, and it is working like a champ. I painted the Lotus Elise in it and now Old Rusty.. There was one issue that I had to solve and that was to add another intake fan to create a bit of overpressure. The reason is that the intake fan and the associated pre and final filters reduce the airflow more then the filters on the exhaust fan. Hence , I had a slight under pressure in the booth and that is not what I wanted . That was a small and easy change.
D3Sshooter I was wondering how your pressure reading ending up after u got your intake fan. I am looking at 5000cfm exhaust fan and trying to think about how to size the intake fan. Perhaps i should think about it in reverse and size the intake first. I have not decided on a solution yet
@@jdpower5552 , calculations is one thing, but I did not think of the double intake filter . That is causing some restrictions for the intake air. The exhaust filter is far less restrictive. This resulted in a under-pressure, despite both fans were the same. So I just added and extra fan on the intake , and that just worked out fine. slight over-pressure...I also made a small hatch in the intake box, so that I can regulate the overpressure... That was the most easy way Hope that helps
Great work as always! You might need a spray gun support/table. just case you have to use different spray guns during the same paint job. Also one window on the door (maybe circular) so you can look inside from the outside avoiding open the door evry time and let dirty air come in.
Al uw video's zijn van top kwaliteit. U kunt het heel goed en beeldend uitleggen. Ik kijk met belangstelling uit naar uw video als de krukas van old Rusty terug is. Waar heeft u zo goed Engels leren spreken. met vriendelijke groet Job Laan
Take note ... When he calculates for U.S. Cubic Feet it is well to note that CFM is a PER MINUTE standard not per hour. So to equate 320,000 ft per hour one needs to first divide it by 60. If you do that then to get CFM Cubic Feet per Minute would be a fan capable of 5,333 CFM at an air velocity of 1 ft / sec. But you would still need to " Dial In " your velocity and balance by using an Air Flow Baffle on the in-coming duct air side while using an Anemometer inside the booth at the exhaust filter via several spot reading 6 or 9 readings / filter along the face of each filter then take the average to determine air current flow speed and adjust the baffle in you incoming air flow stream/fan accordingly; Also a Manometer to measure either for positive, negative or differential air pressure inside the booth, and on the outside filter to determine flow balance thru filters. This video is good info but only gets you to maximum sizing of your fan output needed. Al the above details address what is needed to " Calibrate " the air flow and pressure environment of your booth. If you only get a fan that fits the air movement needed you and only install filters on the pusher fan and exhaust fan, you still run have the risk of having a booth that is too positive or too negative. Too much air flow will prematurely flash your media causing hazing, solvent pop and craters. With too little flow you get dusting, overspray, over mill application etc.
First of all lovely series, explained perfectly. However I pretty sure the equation you have showed is incorrect from what I know the formula should be Q=V*A where Q is air flow (m^3/hr) V is velocity (m/hr) and A is cross section, the area infront of the fan (m^2) and what you have showed isnt the cross section
i dont want to put a downer on things but that exhaust fan you used is an intake fan as its not explosion proof. explosion proof fans have the motor out of the air stream and intake fans have the motor in the air stream
Your paint booth is really amazing. I'm also a hobbiest and I love to repair and restore furniture. I have several Binks Model 7 spray guns, a Model 2100, a Model 115 touch up gun and a Spectrum Gravity gun. I also refurbished my Model 7's. Painted a car back in 1989 with my first Model 7 which I just refurbished. I want to build me a paint booth exactly like yours for painting furniture and cars, I guess I need to build mine a bit larger and it's going to be outside so I'm assuming I should use pressure treated wood. Any advice you can give would be greatly appreciated. Right now I paint my furniture outside and I don't care for that at all. Wish I had a paint booth but I guess someday I'll have it. Thanks for your videos, they're outstanding.
Thanks for the comments, I have used mine now for a while. several cars and it works very well. If I would change anything, then it would be the an extra selectable fan for the intake. Good luck
Excellent video, I appreciate your efforts. I'm in the process of upgrading my home 2 car garage with better exhaust fan. I do auto body collision repair and paint work and had never considered adding an intake fan... Once I have my new exhaust fan (24 inch and 4244 cubic feet per minute) mounted and filtered I may look into the intake side as well. Anything that would minimize wet sand and buffing would be beneficial. TC in Annapolis, Maryland
wow, what a great video! Question, wouldn't a car take up more of the empty space and decrease the volume of the room? wouldn't that help the fan meet the actual AIR volume of the room with a car in it? Your advice is appreciated!
Great video I’m trying to make a small open front paint booth to spray car panels. The main problem I’ve got is how I’m gonna make a huge hole in the wall for the extractor
You have a mistake in your air flow and air speed calculation. You will get max 0.13m/s which is far bellow your country lower limit. But airflowspeed is theoretical. As you have centrally located inlet and outlet, might be in the center you will get 0.3m/s only, however the rest will be underventilated. To reduce the airflow imbalance you can do with inlet and outlet relocation into a diagonal configuration.
@@D3Sshooter ..mistakes happen. However you didn't touch any influence on a functionality so far. For your job might be not so important. But hope you will come later. By my professional experience (most from confectionery production :o) air flow calculation should be linked to air exchange /3.5x2.5x6~50m3, with 4000m3/h you will exchange the box 80times. For most application is it far enough. Nevertheless spraying job is specific as plenty of parameters are linked to the ventilation and air drag/ speed. ..which I am curious about. Great videos, professionally filmed. Keep it rolling:)
Very good points and indeed, the booth does it job. The only issue that I have seen is that the filter (exhaust) clogs up after some time gradually reducing the airflow. If I had to modify the booth ( I stll can), then I would take twice the filter area...
D3Sshooter what about putting baffles in front of the filter so the paint hits the baffle before it hits the filters to extend the time you get before the filters clog. Also i thought booth fans always have he motor separated from the fan blade tube? Is the kosher to have the motor inside the tube? Nice video
The best DIY paint booth hands down. I'm going to build a 12x8 booth in my back yard. Did you only have 1 exhaust fan with smoke machine demonstrates, What is the name of exhaust fan and cfm?
I believe the exhaust fan should be explosion proof = with ex rating to close out the possibility of sparking that would ignite the volatile gas in air
This has been such a useful set of videos. Thank you. I would like to build a booth large enough to spray a car. Do you think the type of exhaust system would be suitable for the size of the booth I would have to build?
Zou je willen delen vanwaar je de infrarood verwarmingspanelen hebt? Ik ben namelijk ook aan het kijken om dergelijke panelen in mijn garage te hangen, maar ze variëren enorm in prijs en ik weet niet meteen wat nu goed is en wat niet. Mvg Giel
Hi. Where did you purchase the fans? I'm planning a smaller booth for my guitar business, but am having trouble finding explosion-proof fan suppliers in France.
The Fans I used are arc free, so not really explosion free. But so far not a issue... www.ventilatieland.nl/categorieen/7500/ventilatoren.html they have all kind of Fans
You did a beautiful job, but that is nowhere near enough water and oil filtration for your spray gun. You need at least a 3 stage system if you plan to paint anything without contamination.
Thanks this was a fun vlog to watch, but not realy the end i think, show us the final results:-) when you finish the intake and painting, and above that show us the thaning of your girlfriend in there (lol):-), as always Thumps up.
Awesome series on the paint booth. How is it working out for you. Would this set up be efficient for painting cabinets? What does the temp stay inside with the infrared heaters. Great job.. Happy New Year from Tn, USA
so far , I have painted several cars and parts without any issue and great results, you can see some of that on my channel on old rusty, This would work for cabinets, the temperature stays at 35 max, with the blowers it drops pending the ambient temp
Dear Sir, Once a Car is fully sand blasted / Soda Blasted from all sides and when all the Paint / Putty Primer etc has been stripped off the car do we have to completely wash the Car with water to ensure that the soda blast / sand blast residue is taken off and cleaned just before the application of Epoxy Primer on the Bare Metal surface of the Car? In case of Soda Grit the water will dissolve it and remove it from the deep door corners etc and in case of sand air pressure has to be used to remove the reside from these areas. Kindly clarify. Sincere thanks in advance. Have a wonderful day.
Well my take is : Dry clean the Soda blast residue. The problem with water is that it dissolves the soda and creeps and drips in all places. So, a very good airblast will do a lot. Then really degrease the bear metal, with an all purpose prepaint degreaser like Holdtight 102 .. If you use water , oxidation will start immediate even if you don't see it... That is what I would do, but then again I am no expert in this.. have a great day as well
@@D3Sshooter thanks for the lead. I checked them out, then found a much cheaper alternative which I've ordered a 26" diameter, 25' long tube. I won't bother mentioning the company name until such time as I have received, installed, then used it for a while. Fingers crossed! Marty
To update you, in the end I decided that the flexible tube wasn't going to work (too inflexable and heavy to be readily supported), so I went with a fixed wall booth and a curved plywood exhaust tunnel . Thanks again thought for the many excellent ideas you shared with us, some of which I used in my booth. Cheers from Canada!
@@D3Sshooter Definitely! I'm installing the filter system and still have the lights and the side wall to reinstall, so as soon as that's done I'll place it on my channel then let you know.
@@D3Sshooter sir my manufacturing factory is 50 feet length * 22 feet wide and we are using oxy fuel gas cutting machines which cause smoke inside the factory and i want to know that how we can send that smoke outside the factory using exhaust ?
@@ieltssolutions5634 , I see. Yes in that situation the same situation calculation can be used. but keep in mind that you will need to use the refresh rate of air that your local legislation for health and seafty describers
Great job. This serie of video about paint booth has inspired me a lot. Please i'm just a bit confused about your air flow calculation. I think the surface to consider in the calculaton should be the surface to which the velocity is perpendicular to. It means that for your case, instead of using the width (W) you should use the length (L). Could you please check and advise. If my interpretation of the calculation is not correct I really do apologize. Also, is it the same procedure to follow for vertical air flow? Thanks...
Thanks for the comments, in fact its all the air in the booth that should be replaced within a certain time. After all you spray in differend locations. It is better to have all air incoming on the top and get it out on the bottom... the bigger the surface for the filters the better as the air velocity goes down.
Sir good day,, can you please give me the floor plan drawing of the paintbooth, and the location of the two exhaust fan,, thank you ang happy new year sir
Great videos.... do u really need a fan blowing air in ?? Could u not just have filtered air inlets and let the extractor pull the air through... thanks
Thanks for the comments... Yes you do as I wanted a slight overpressure in the boot. If you do not want an over pressure but underpressure then that is possible
The model I used is explosion proof , but only the basic version, The principle is that all the air in the boot should be replaced about every 10 to 25 seconds. So you will need to calculate what you will need. There are many store that sell fans or extractor. ventilatorland in the Nederlands is one
Hi, your math doesn't make sense to me. 0.6 is bigger than 0.3, not smaller. 3.6x2.4x0.6x3600=18,662. Your 4000 m3/hr fan will give you a velocity of about 0.13 m/s. Or did I misunderstand something?
This is the best DIY tutorial for a paintbooth on youtube!!

Thanks for the comments, that is a couple of fire exthinguisers
this is really good
KAYIWA PHILIP thanks
Awesome series on the paint booth. How is it working out for you. Would this set up be efficient for painting cabinets? What does the temp stay inside with the infrared heaters. Great job.. Happy New Year from Tn, USA
so far , I have painted several cars and parts without any issue and great results, you can see some of that on my channel on old rusty, This would work for cabinets, the temperature stays at 35 max, with the blowers it drops pending the ambient temp
@@D3Sshooter what is 35 in relation to Fahrenheit.
Drew Portdaven that is about 95
@@D3Sshooter thank you
great stuff
Grate tutorial !! What kind of fans do you use and where did you get them?
Thanks for the comments, they are from this site.... there are many types available.. www.ventilatieland.nl/axiaalventilator-rond-aros
6:25 where does this 3600 number come from?
11:40 what is an arcing fan?
does the filtration filter out isocynates?
Thanks for the comments, not my filter
Dear Sir, Once a Car is fully sand blasted / Soda Blasted from all sides and when all the Paint / Putty Primer etc has been stripped off the car do we have to completely wash the Car with water to ensure that the soda blast / sand blast residue is taken off and cleaned just before the application of Epoxy Primer on the Bare Metal surface of the Car? In case of Soda Grit the water will dissolve it and remove it from the deep door corners etc and in case of sand air pressure has to be used to remove the reside from these areas. Kindly clarify. Sincere thanks in advance. Have a wonderful day.
Well my take is : Dry clean the Soda blast residue. The problem with water is that it dissolves the soda and creeps and drips in all places. So, a very good airblast will do a lot. Then really degrease the bear metal, with an all purpose prepaint degreaser like Holdtight 102 .. If you use water , oxidation will start immediate even if you don't see it... That is what I would do, but then again I am no expert in this.. have a great day as well
Terrific video! Are you aware of any supplier of flexible exhause tubing (for use with a stowable spray booth)?
Thanks for the comments, yes I do have a look at HBM machines and look for ventilation... they have those flex large diameter tubes
@@D3Sshooter thanks for the lead. I checked them out, then found a much cheaper alternative which I've ordered a 26" diameter, 25' long tube. I won't bother mentioning the company name until such time as I have received, installed, then used it for a while. Fingers crossed!
Marty
To update you, in the end I decided that the flexible tube wasn't going to work (too inflexable and heavy to be readily supported), so I went with a fixed wall booth and a curved plywood exhaust tunnel
. Thanks again thought for the many excellent ideas you shared with us, some of which I used in my booth. Cheers from Canada!
@@ApexWoodworks Thanks for coming back and good luck.... maybe a video of the booth in working ?
@@D3Sshooter Definitely! I'm installing the filter system and still have the lights and the side wall to reinstall, so as soon as that's done I'll place it on my channel then let you know.
Goe dag
Mag vraagje waar heb je de ventilators gekocht ?
Tnx alvast

Ventilatorland in Nederland
Would you help me design my paint booth?
Thank you very much
Is your booth flame proof?
To some extend , and so far never had an issue. Of course this is not for daily painting
@@D3Sshooter ok cheers. How effective are you finding the inferred heating panels?
Nice work
TXS
Can you reach out to me I need some advice about the formula you used for air velocity
Hi can you tell me the name of the fan that you got so I can order one just like it
www.airroxy24.net , you find them in Poland. I use the same fan under the brand "Ventus"
@@TTRVision That's a porn site!
sir i have 50 feet long and 22 feet wide godown can i use this technique if yes should i have to fit exhaust in or outside ?
Not sure what the question is... in principle the methods are the same. Can you explain what you would mean.... sorry ?
@@D3Sshooter sir my manufacturing factory is 50 feet length * 22 feet wide and we are using oxy fuel gas cutting machines which cause smoke inside the factory and i want to know that how we can send that smoke outside the factory using exhaust ?
@@ieltssolutions5634 , I see. Yes in that situation the same situation calculation can be used. but keep in mind that you will need to use the refresh rate of air that your local legislation for health and seafty describers
Where can I find that roll of filter fabric that he has? Anybody know?
Thanks for the comments, there is shop in the Nederlands.. but just google for sprayboot filters
Great job. This serie of video about paint booth has inspired me a lot. Please i'm just a bit confused about your air flow calculation. I think the surface to consider in the calculaton should be the surface to which the velocity is perpendicular to. It means that for your case, instead of using the width (W) you should use the length (L).
Could you please check and advise. If my interpretation of the calculation is not correct I really do apologize.
Also, is it the same procedure to follow for vertical air flow?
Thanks...
Thanks for the comments, in fact its all the air in the booth that should be replaced within a certain time. After all you spray in differend locations. It is better to have all air incoming on the top and get it out on the bottom... the bigger the surface for the filters the better as the air velocity goes down.
@@D3Sshooter Thanks for reply. Do you have any tips on how to estimate the surface for filters? Thanks
Sir good day,, can you please give me the floor plan drawing of the paintbooth, and the location of the two exhaust fan,, thank you ang happy new year sir
I don't have that available as such a always build out of my head and use common sense/ sorry
Where do you get the filter roll from?
Great videos.... do u really need a fan blowing air in ?? Could u not just have filtered air inlets and let the extractor pull the air through... thanks
Thanks for the comments... Yes you do as I wanted a slight overpressure in the boot. If you do not want an over pressure but underpressure then that is possible
@@D3Sshooter ok thanks I'll look into pressures
@@D3Sshooter And what is the size of the intake fan then? Do you you use the same as for the exhaust? Great job there...
can u link the fan? link the brand on model
Have a look at ventilatorland .nl
Please how to contact you ? I have a lot of difficulty wiring my engine. how to contact you to send you pictures of my assembly?
How much is total cost?
all inclusive , wood, fans, electricity, filters, lights, heathing = 2000 euro
About how much was the total cost
About 2000 euro
What's the contact number of this guy installing the paint booth.
what kind of extractor is that? how can I get it? how much cfm do you extract?
The model I used is explosion proof , but only the basic version, The principle is that all the air in the boot should be replaced about every 10 to 25 seconds. So you will need to calculate what you will need. There are many store that sell fans or extractor. ventilatorland in the Nederlands is one
Hi, your math doesn't make sense to me. 0.6 is bigger than 0.3, not smaller. 3.6x2.4x0.6x3600=18,662. Your 4000 m3/hr fan will give you a velocity of about 0.13 m/s. Or did I misunderstand something?
You are right Rick, I goofed up with the calculation but check my errata video on part 4.. there I explain it where I stated it wrong.... TXS
where did you get the exhaust fan from? Thanks
Thanks for the comments...,ventilatorland nl
Can u double the fan I mean the sucker fan
