Blowout bend 135° ASBEF / ASBEA
Blowout bend as a duct bend with attached protective grille.
Opening inclination 135°.
The rebates are sealed with sealing compound.
Painting in all RAL standard colors possible,
Duct connection by 4-hole air duct profile,
Standard: Up to edge length 1000 m profile 20 mm,
up to edge length 2499 mm profile 30 mm,
from edge length 2500 mm profile 40 mm.
Design exclusively for exhaust air.
The ASBEA can be used as an intake hood at an air intake velocity ≤ 2.5 m/s and taking into account regional weather conditions.
Blowout bends are conditionally firedamp proof. When the exhaust air system is at a standstill, moisture, snow or dust can enter the pipe system. This can lead to water accumulation. Therefore, a condensate drain should be provided below the bend. At high humidity and temperatures below freezing point, there is a risk of icing of the protective grille.
