Self-Adjusting
AL is a self-adjusting exhaust vent featuring fixed flow for use in central ventilation systems.
Attractive Design
AL has an aerodynamic design and provides a perfect match between high technical performances and aesthetic requirements.
Pre-Determined Extraction Flow
The AL airflow element is a rigid flap that provides a pre-determined extraction flow between 50-150 Pa.
The AL self-adjusting exhaust vent provides a perfect match between high technical performances and aesthetic requirements. AL features fixed flow and provides uniform architectural solutions to kitchen, bathroom, and WC ventilation problems. The airflow element is a rigid flap that provides a pre-determined extraction flow between 50-150 Pa.
The AL has an intelligent design, is executed in white polystyrene, and features mounting rings in diameter 100 or 125 mm, plastic renovation plates, and a silencer module.

Vents characterized by their standard noise attenuation qualities Dn,e,w (C) and their acoustic power level Lw (at a stable extraction flow) measured in compliance with the specificationin pr EN 13141-2.
The sound pressure level due to the vents own noise is given by the formula:
Lp = Lw - 10 log (V/12,5) in dB(A) where V is the volume of the room in m
3
Example: for a 40 m
3
room, and Lw = 31 dB(A), Lp = 26 dB(A).
Noise attenuation Dn,e,w (C) is determnined using the Ø 125 sleeve, the opening being fitted with or without a silencer module.
