In hot countries, they should make this stock-standard equipment plus one or two more as optional-extra.sss. 2x air intake, 1x air exhaust (spinning direction hack) for vehicles without sun roofs. And solar-cell linned additional plastic-layer insulator to power interior fans hacks to vent the entire vehicle when the thingies are not spinning (parked under the sun during supermarket run)...
Hi, Bought one of these 27 August, 2021, and as a reviewer stated, it only works when driving. I have done some research on my particular fan with CCTV & Windfinder app... It doesn't start to rotate until around 18-20 mph wind strength when parked on my drive. So resigned to a 'fail' this time, I decided that at least, it lets out hot air and doesn't leak when it rains. [Ford Transit Custom]. What has decided me to enquire now, is I recently pulled up next to an identical FTC at a local business, only to see his LP flettner spin happily in a little wind where mine was motionless only 5 yds away? I am in the process of slowly backing off the securing bolts, in case it is my fault overtightening them. But no improvement yet.....
@@LewisBotham-pv6dj Hi Lewis, the answer is No. Have tried loosening off the securing screws but still only starts rotating 'slowly' when wind speed is over 20 mph... 2nd thought I've had is are the roof bars interrupting/reducing the airflow/wind to the Flettner? Plus side is I have a waterproof vent in the roof! I now have a Propex LPG heater installed which can suck in fresh air (unheated) if it gets too hot in the Summer (what's that?)
Hello, if installed correctly our ventilators are virtually silent. For more information please visit our FAQ: www.flettner.co.uk/flettner-frequently-asked-questions/

Should move freely with little wind
Hi mate did you get it sorted? I’m in the same position now?

What keeps it from leaking into the trailer or vehicle?
Waterproof Silicone sealant
Can you put this in automatic wash
Yes you can do this.
@@flettnerventilator9769 thanks
Does it make any noise when you drive fast?
