BKZ

The BKZ supply air valve is designed for draft-free and extremely quiet air distribution with an injector effect, suitable for residential buildings, offices, and hotels.

Suitable for airflows from 20 to 120 m³/h.
Offers a variable air distribution pattern.
Throw length and direction can be adjusted to match room shape and size using nozzles.
Balances temperature differences of up to ±6°C between supply air and room air.
Complies with DIN EN 13779 standards.

Design
The diffuser consists of nozzles (1) integrated into a perforated plate
Nozzles can be adjusted parallel, outward, or inward-angled for the desired air distribution
Pipe connection with sleeve and rubber seal
Delivered with an adjustment plate

Adjustment
Adjustments are made using the included adjustment plates and self-adhesive plastic rings attached to the plate

Function
The supplied air is a mixture of air passing through the nozzles and air passing through the perforated front plate
Air distribution is determined by the nozzle direction:
Nozzles facing each other → Longer throw distance
Nozzles facing outward → Shorter throw distance
Nozzles facing the same direction → Air directed accordingly

Installation
BKZ is inserted into the spiral duct so that it rests against the wall
Pre-installed seal ensures a tight fit against the duct
