We have developed a simpler version of a fresh air valve with a diameter of 100mm, especially for those who want to be able to regulate the air supply manually by opening and closing it themselves.
The valve has a circular connection in the supplied pipe and a square frame on the outside, with a replaceable grid in three different colors.
It comes standard in white, but silver and black are also available as options.
This manual valve is perfect for use in storage rooms, sheds, garages and similar spaces.
