Supply Air Valve - 125mm

Heat Recovery Direct

The valve is made of polypropylene plastic that can withstand temperatures up to 120 degrees Celsius. The material keeps its color over time and is recyclable.

Simple and efficient to install as it doesn't require any tools to fit and secure. This valve is designed to be used along with the 125mm Plenum.

Round valve with aerodynamically design with good characteristics in terms of noise level, air flow capacity and pressure drop. The valve is mounted in a ceiling or a wall and is intended for ventilation systems with a relatively high pressure drop.

The valve is pushed into the frame. The cone is screwed out or in the number of turns giving the gap an opening in mm corresponding to pressure drop and the desired air flow, when dismantling, the valve is pushed sideways and then pulled out.

Standard white (RAL 9003).
