Vent Systems 100 mm / 4" Inch - Air Vent Duct Connector Flange - Plastic Ventilation Pipe with Valve - Ducting Connector for Round Flexible or Straight Pipes, Ventilation System HVAC

This is a key part if your are venting your air conditioner hose through a wall vent attachment. I bought two other parts which would be ideal if sold as a kit. And that was the threaded attachment a standard blank plate to add additional support. I was used in my home as an attachment to a kydex panel fitted over the window. Highly recommended if you have a push open window so you have 4 flat edges of the window to attach Velcro no hot air coming back in at all. First time ever.

Come very quickly good quality

Accurate size (not always the case with vent and ducting products). Is a little noisy but I’ve sorted that with a thin line of silicone where the flap contacts the body

This simple non-return air vent does it's job reasonably well. When it arrived I saw it would be very noisy and clatter a lot in the wind. I modified it by making an adjustable weight arm that holds it shut better than it otherwise would. I've also put a little bit of lithium grease around the inner join to help stop it bouncing when closeing under gravity. Even with these modifications, I still hear it opening and slamming shut on blustery days. It's a lot less annoying after modification than it could have been mind! It's not exactly obvious which way around it's supposed to work. Would be nice to include a simple arrow showing which way to fit it. Not too tricky to work out by experiment of course.

ok

Yes

Not very tough and easily broken

Great exhaust vent! I have this installed into my ceiling to vent my grow tent. I like that the flap will close if I shut my exhaust fan off or the power goes off. Nothing can fall back into my 6” hose and into my exhaust fan. Well made and reliable.

Cumple con lo que se espera solo deberían hacer más rígido el material ya que al instalarlo casi se quebra con la fuerza de los tornillos, el plástico que tiene en medio que se mueve con el aire se lo quite ya que no lo veo necesario por contenerlo ya la campana.

I recently redid my workshop and moved my spray booth bench to a more useful area. Unfortunately the booth was then up against a wall and I needed to drill 2 4" holes into the sheetrock so that the exhaust pipe would fit through cleanly. I prices similar tools at the big box stores and they were sometimes double the price of this bit. It cuts through drywall quickly and leaves perfect 4" holes for you. Another great tool for the toolbox ready for the next job.
