*Needed a cooler for a work cubicle **Fastly.Cool** . It did just what I needed, so easy to used and really cooled the space. I am glad that I got it and would buy it again.*
I have installed 2 such units on my roof and after 19 years they are still in top form. I bought these two from USA and bought them home as check in luggage.
I have a couple of whirlybirds on my roof that are very similiar to this brand . They are about 20 years old they but do not have the fan. I noticed one was making squeeking noises so I undid the three screws that secure the rotating section to the stationry tube. Note it is unnecessary to undo the single nut on end of the shaft. I discovered the whirlybird bearings are not designed to be removed and replaced with new bearings so I hosed the dust out of the bearngs using WD40 and gave the framework a few spins. The centrifigal force caused black gunk to issue from the bearings. I wiped the black gunk with a rag and repeated this process several times. Finally I applied several drops of sewing machine oil to the bearings and puffed some powdered graphite onto the oil for good measure. The bearings no longer squeek and the repairs cost nothing.
My experience with whirlybirds is they reduce the temperature in the ceiling void by about 10 to 15 degrees Celsius. This prevents excessive heat on hot days from passing through the ceiling plaster board and heating up the living area inside the house. Wind causes the whirly bird to spin and centrifigal force causes hot air to be flung out of the gaps between the vanes. This causes a reduction in air pressure within the ceiling void which becomes normalised by cooler air being drawn into the ceiling void through ventilators in the eves.
I showed a whirlybird in a video and it really confused many overseas viewers. Where I live it was shit with a massive hail storm and so many whirly birds were damaged. Even the tough metal ones.
Yes we get hail here too but that does not stop people parking their cars in the street...if it gets damaged in a severe hail storm get it replaced with the insurance just like you do with the dents in your car...usually even when dented they still work :)
@nay1978miles The hot air in the roof cavity rises and the airflow actually turns the ventilator further aiding the removal of hot air. Their main benefit is that when a slight wind is blowing that would normally reduce the airflow out of a straight tube, the design of the turbine ensures a low pressure area at the top of the vent to draw away the air from within the roof cavity. After fitting two in my roof the air temperature up there, dropped by about 15 - 20 degrees on hot days
Twista vents are also Australian made and are 420mm not 300mm like edmonds and other brands, the Twista vents are also much stronger as they are not build from aluminium. They have also been around for more then 15 years. Makes your Rolls Royce vent look like a cheap Datsun 120Y. The vents work on days without any wind as the hot air from the roof causes the vent to spin.
+Tyson Cierpial I think you've been watching far too many television advertising blurbs. There is a reason for the domestic ventilators been made to a 300mm size...they fit in the space that a roof tile takes up, logical when you think about it! Wouldn't be very efficient to put a 400mm vent over a 300mm hole.There are of course many commercial ventilators of varying sizes to suit industrial applications. Its always very easy to be critical from the armchair!
@@InsulationAustralia you really should check out the Twista vents made in Sydney ! they really are over engineered to the buggery . 10 times better than any other domestic made vent in Australia . only other vent that comes close is the edmonds Hurricane . industrial quality . the rolls royce of vents in the world !
I put one on the roof of my hot garage and it dropped the temp in there 20 deg F. Even without the spinning, just having the hole in the roof lets heat out. I can now go in my garage and work without dying from heat.
true natures aetheric free energy at work...now we only need to upsize these turbines 3000percent install them up on giant building lift shafts, install neodymium magnets to spin along the wings and use coppercoils without iron as stator coils nad generate real free energy!!!
They should have quality bearings. Spend the extra money and mount them level to the ground not roof, use a level. Also, make sure you have plenty of eave vents to allow air in at the roof edge, no one wants the attic to suck air from inside the house, that would suck.
The management where I live doesn't feel that is very important, other's bathroom stink is blown into my apartment I complain but nothing ever done, lazy underqualified individuals that are a harm to other's causing health problems. I survived cancer already probably already entered my body by now, I just wish these individuals had more respect for the fact of job responsibility.
John I have a camp near the opal fields of Lightning Ridge and it is a skillion roof made from 75mm polystyrene sandwich panel - no roof cavity as such. It gets very hot up here and I wondered if a ventalator would be effective in reducing heat inside without a ceiling cavity.
Yes it would be as long as you are able to close it off for the cold winters. There is a company called Aplelite that not only make roof ventilators but a ceiling grille that can be closed off for winter.As long as there is airflow(hot air rises) you would benefit...Even in 45 degree heat! You can also put a garbage bag over the vent in winter as well :)
I saw industrial whirly birds on a huge shed at the local tip which were spinning very fast indeed although when i went inside the shed comunities of spiders had set up home in the throat of the vents and the webs were barely moving ?????
I can't comment on what you saw but I can say this...Over the years I've installed many ventilators and when you cut the hole in the roof or remove the roof tile hot air instantly pours out and when the ventilator is fitted even more so. I have no axe to grind as I am no longer self employed or working within the industry but would still recommend roof ventilators to my friends and anyone who cares about home comfort and roof health. I have seen many webs in ventilator throats over the years and they do move slightly when you are close to them...Spiders seem to like it because of the airflow through the narrow opening funnels insects their way...Clever little insects! Its not about FAST airflow...It's about airflow. How close to the webs were you Shayne? Most industrial sheds are at least 5 metres (15 feet plus) to the eaves and probably 7 to the roof apex so a little difficult to see clearly. I would suggest that if the council cleaned out the mass of webs they would get better air flow. It's just a thought :)
+ReddmanDGZ They will exhaust far more hot air than a static vent...especially when the wind blows a little. Powered vents will aggressively exhaust hot air and can be set up with a thermostat to automatically switch on at a certain air temp. Depends on budget and whether you want a passive green vent and how much hot air you need to move.
+InsulationAustralia There are now some really well designed solar powered roof ventilators available which work all year round...In Australia a well ventilated roof is a healthy roof!
If the roof temperatures are very hot it may spin a little...the main thin is that is is venting hot air to the outside. If the wind blows well even better for removing hot air from your roof cavity.
10 year warranty roofs last longer whats the point,the real whirly bird is lifetime ,and plastic breaks after a while hhmmmm i question your work ethics ,and whats with these no face peolple posting lol no face no balls lol
+Don Viau Very interesting logic...A house lasts longer than my refrigerator, my washing machine, my carpet and my water heater...Do you question the ethics of the suppliers of all of these products? No face...Didn't you watch the video? or did you have your eyes closed...Unless I'm mistaken my face is very much in the video...Balls intact!!
Gary I saw an animation video about this. It says that air becomes hot when it enters. As it becomes hotter, the air will rise to the top and because there is no ventilator, the hot air will move to the bottom creating stagnant unhealthy air. When there is ventilator, the ventilator will suck the hot air out of the roof.
Hey buddy. Can i put something to make the turbine to stop spinning? I have a air circulation but I don't want the turbine to spin to show that it's active. Would it be a good idea to stop the turbine from spinning?
I still don't get what is the different compare with other turbine wind turbine vent has two problems. 1. cannot shutdown on winter, make house too cold 2. rain - water may get inside the roof
You have to separate the roof cavity to the building envelope. With an insulated roof or ceiling venting the roof makes no difference to the house temperature.
I had to replace one that was hit by lightning. It hit the center of the top and blew a hole in the decking. I've only seen that happen once. So yes it could happen.
There won't be a next time...:) because I'm not in the industry anymore, but I get your point...we could have done it a lot better. Thanks for your feedback.
I'm sorry for not replying sooner, I don't visit here very often. Yes you can install a system that sucks out hot air. You can install a ceiling vent and duct it to a roof ventilator or a powered fan to get rid of hot air.
Definitely! But it would be a very small amount of electricity. maybe enough to slowly charge a cell phone. The added resistance (from the generators brushes) would also slow the vent down a bit.
Can you mention where to find them. I was about to buy something Bunnings was selling for $59 and it doesn't have a fan. And are there different models to suit tiled or tin roofs.
Directly vented to a room or if you have ceiling vents is the most aggressive way to remove hot air, there will be a temperature reduction overall in the house.
God damn!! Where is the scientific proof of these things working? Thermal imaging, thermocouples, airflow tests, data on a spreadsheet... ANYTHING! Can anyone link me to a website?
Hi Barrie, have you nothing better to do with your time than negativity critique an old but accurate representation of what good ventilation is about? Really???Here's an idea...why don't you do some research and put up a video that that correctly explains what ventilators do. Maybe better still go and crawl around a few thousand ceiling cavities, install a thousand or so ventilators and get back to me with some good practical advice. As always it is much easier to criticize than encourage, sadly you have chosen the easy option. ,
Good ventilation yes. Insulation yes. Using a device that was developed nearly 100 years ago and touted by every shonky sales person from Sydney to Shanghai not good. Try doing a bit of research yourself ( by the way some of these so called turbo vents are made by child labour in other countries)

Um the turbine vent is always spinning. There’s something wrong with yours. That will cause rain to get in your roof
What stops the water getting pushed in with wind Gust’s?
Very interesting, I always thought those things worked with some kind of motor, who knew...

Will this cause heat to leave my house in winter?
I know how roof vents work but idk if it sucks inside air out or sucks outside air in
@vincevega0
None, either the wind from any direction or hot air rising from the inside makes it spin.

You have to separate the roof cavity to the building envelope. With an insulated roof or ceiling venting the roof makes no difference to the house temperature.
I swear I thought that was for a ceiling fan.
where can we buy these in the U.S.
Is it safety for lightning and thunders?
Yes no problems what so ever...The Australian ones are designed to cope with over 100mph (160kmh) As long as no flying material hits them...

I have 2 but one does let the rain it the other not the only way to rectify it as far as I can tell is to put a bag over it during tropical storm
They wear Out…… Rain Blows in…….. Bad Idea……… + Roof Leaks!
Will it only spin in one direction? just anti-clockwise?
yes but it doesn't matter as long as it's spinning :)
Can u duct a inner fan to the inside to help blow air up and out?

is it possible to add an auto generator to these vents and get electricity out of them as they spin? these vents always spin no matter what.
Definitely! But it would be a very small amount of electricity. maybe enough to slowly charge a cell phone. The added resistance (from the generators brushes) would also slow the vent down a bit.
I installed a 10” solar fan underneath it, inside the attic and help cool the attic down more.
