ELZ telescopic air valves without thermal insulation supply
fresh air to indoor spaces. One end of the ELZ valve has an
outdoor air intake vent with louvres and a protective mesh.
The other — indoor — end has a round air supply valve with an
adjustable opening. The opening size can be adjusted smoothly
by rotating the disk closure, or in a three-step adjustment
procedure with a pull cable. The outdoor air intake vent and the air supply
valve are connected via a telescopic tube.
The ELZ telescopic air valve is designed for installation in the outer
wall of the building. The maximum wall thickness should be
350 mm or 400 mm, depending on the size of the ELZ valve.
The minimum ceiling clearance for the ELZ valve is 100 mm.
The area to be ventilated should be provided with two ELZ
valves aligned opposite to each other for the best air flow rate.
The outdoor air intake vent is finished in grey and the air
intake valve is finished in white.
The ELZ telescopic air valves are intended for single-family
houses and apartments in multi-family buildings.
