Supply air valves and exhaust air valves

Photo of product family: Supply air valves and exhaust air valves

 

We offer a comprehensive range of ventilation air supply and extract valves for domestic and commercial ventilation applications.
Air valves can be divided according to materials they are made of that is:

  • steel sheet with RAL 9016 powder-coated finish (codes KW, KWV, KWI, KWO, KN, KNV, KNI and KNT) or RAL 9010 powder-coated finish
  • stainless steel - KW-K and KN-K air valves
  • chrome-nickel - KCN air valves
  • plastic - KPP air valves and ELZ and ELZ-I telescopic air valves

Air valves are available in a diameter range from 80 to 250 mm and depending on a type are delivered with or without a mounting frames (rings). Mounting frames are also available to buy separately check - mounting frames category

Wall diffuser

HHS wall diffuser for fresh air supply. Male connector with
gasket for fast connection with SPIRAL® duct.

Powder painted
with white RAL 9010 colour which provides additional
protection from corrosion in places with high humidity, such
as bathrooms.
An excellent choice when celling mounting is out of the scope
or the interior design requires a wall diffuser. It can be used
in offices, residential houses and mounted just under the
ceiling as well.

Front cover can be opened to make the maintenance
and cleaning easier, and the perforation on it ensures even airflow.

Steel supply air valves for ceiling and wall mounting

 

KN air supply valves can be installed in the ceiling, on the wall
or directly in the mouth of a ventilation duct using a dedicated
RM mounting frame. They allow smooth adjustment of the air
exhaust flow rate by rotating the disk closure in the centre.

The air supply flow depends on the disk closure distance from
the round bezel and it is set with a locknut.
The carefully designed geometry of the valve
guarantees low noise level as well as quick and easy installation.

KN-K air supply valves can be installed in the ceiling, on the
wall or directly in the mouth of a ventilation duct using a
dedicated RM mounting frame. They allow smooth adjustment
of the air exhaust flow rate by rotating the disk closure in the
centre.

The air flow rate depends on the opening ratio, i.e.
the distance between the disk closure distance and the round
bezel, and it is set with a locknut. The carefully designed
geometry of the valve guarantees low noise level as well as
quick and easy installation.

Chrome-nickel ventilation cap supply and roof valve

KCN air valves are designed for both air supply and air exhaust
ductwork. They enable smooth and precise adjustment of the
air flow rate.

The adjustable disk closure has been designed for
high air flow performance both in air supply and air exhaust
modes. The surface finish has a brushed texture. The KCN air
valves have a very high aesthetic value, a long service life,
and are very easy to install.

Plastic air valve

 

KPP plastic air valves are made from white PVC and as a result, they are
corrosion-resistant. The air flow rate is adjusted by twisting
the disk closure in and out of the bezel. The opening ratio is
fixed with a locknut.

The carefully designed geometry of the valve guarantees low noise levels.
The KPP air valve is fastened to the ductwork end via a mounting frame.
The KPP valve only needs to be press-fitted in the mounting frame.

Telescopic insulated supply air valve

 

ELZ-I telescopic air valves with thermal insulation supply
fresh air to indoor spaces. One end of the ELZ-I 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 thermal insulation cladding is installed inside the tube
and on the disk closure.

The ELZ-I telescopic air valve is designed for installation in
the outer wall of the building. The maximum wall thickness
is 400 mm. The minimum ceiling clearance for the ELZ-I valve
is 100 mm. The area to be ventilated should be provided with two ELZ-I
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-I telescopic air valves are intended for single-family
houses and apartments in multi-family buildings.
