Made in Udmurtia :
Excellent replacement for outdated trickle vents!
On request, you can choose two types of filtration F5 (fine) and G3 (coarse). For warm regions, I recommend G3, as it allows more air to pass through. Also for regions with high temperatures, special deflectors can be installed on the roof to increase air draft.
Thanks for quick delivery! The installation turned out to be simple. I have already sold 12 filters to my customers.
The only valve that I have found on the market for installation in a fixed frame. Good protection against street noise and dust. Now it is in trend.
The video tutorial helped a lot, thanks! I ordered graphite color, it is also in stock, keep in mind. You can order almost any color, ask the manager.
