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.

ASBEF:
Design exclusively for exhaust air.

ASBEA:
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.

Notice:
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.
