Adjustable plastic ventilators for use as fresh air intakes or air exhausts. Easily installed in plastic windshield or metal cowling.
Model F325A: Large tabs on lower flange and tapered profile make this vent ideal for higher airspeeds. Mounts in 3-1/4 diameter opening in plastic windshield or metal cowling.
Didnt have a 3-1/4 hole drill but i had a,3 inch. So i carefully exspanded the hole using a dremel tool . Installed into the lexan quite good. Simple solution for getting some air into my new designed door . I would recomend this product for lightsport aircraft
Functions as designed good quality have used same item previously put in motorcycle winshields
I purchased two pairs of these snap-vents for use on my Rally-cross GTI. I had replaced all my glass with lexan windows and needed a way to aid ventilation. After a brief google search I found these vents. Some have said that using the recommended 3.25 hole saw is not advisable as it makes the hole too big. This is not a fault of the hole saw size but excessive run out in your drill/or drill chuck. Use a good drill and go slowly and you get perfect results. I used an air drill.
Thank you very much for the quick response and delivery very satisfied with product thank you very much cheers
The installation was easy and the finished appearance is very good. I am satisfied that I have received exactly what I expected.
Greatly packaged and efficient service.
Easy to install and use. I think they are a good buy for the price. Regarding the previous review, perhaps they work better in some applications than others, but I was satisfied with the results.
These vents were easy enough to install in my motorcycles windshield, and look like factory installed. Unfortunately, they didnt give me the airflow I was hoping for. I have a fairly long beard, and was trying to eliminate the Burble, which causes my beard to fly up into my face and field of view. Back to the drawing board I go. Thanks.
These vent fit too loose in an appropriate 3 1/4 hole. I had to order another set with the tension wire on them to fit correctly in my Cessna side window. I thicker acrylic window may be ok for them. Or drill an undersized hole. The snap vent itself is good quality but in my case fit way too loose
I have two of these, on my Mini-Max Eros. No matter how I position them, they will not stay shut with the engine just idling on the ground. I have yet, to fly the plane. Maybe they will close, with enough airflow. Any ideas to make them behave, would be appreciated.
These snap into the opening where they will be installed. They have a vent on one side. If you rotate the vent towards the front of the aircraft, the air will flow in. If you twist it 180 degrees, the airflow will stop. It will not be airtight but the air will not be flowing in. You could use a seal to create an airtight closed position but we do not have any details on exactly how that is done.
This will depend on your application. Since this is an experimental part it is up to you to decide where you think this will best be placed. There are general installation instructions here under the documents tab that you can refer to. This vent has been used in plexiglass/lexan door windows in the past, but can be used in other areas of the aircraft.
