EV is a circular exhaust air valve used for air evacuation.
The valve is a practical ventilation solution for installations with constant or variable air flow.
It is recommended for small rooms with wall or ceiling mounting.
EV is equipped with adjustable center disc and mounting frame.
Screwing/unscrewing the center disc increases/decreases the space between the disc and the frame, thus obtaining the adjustment of the air flow.
Adjusting the disc is easy and is done manually.
The mounting frame is provided with holes and is used to attach the valve to the wall or ceiling.
The valve is provided with a sealing gasket.
