Slot Ventilator CW-40 / CB-40
Technical data. Area 40cm²
Easy to install!
Suitable for installation in upper window frame/casement.
When installing in a double-pane window frame, seal with a dust seal strip around the holes between the frames.
This is to avoid condensation.
Prevent cracking of the window frame/casement when making holes.
To prevent cracking, use clamps to tighten down a wooden block against the surface where the drill is to pass through the frame/casement.
Avoid drilling too close to window glass and edges of the window frame/casement to prevent cracking.
For optimum performance, use silicone along the oversite of the vent.![]()
