The HRB roof hood is designed to be used as a fresh air or exhaust air grille in comfort and industrial installations. The hood consists of circular lamellas with small animals-proof wire mesh on the inside, screwed or pop rivited to the strut to which the roof is also secured. The roof is normally conical for good water drainage, but is also available in other designs. It is part of the same series, EKO-Design Line, as HB, HBJ, HBF and HBK and used in environments with specific design requirements. Can also be combined with a base plate.
The HRB roof hood is manufactured as standard in galvanised aluminium (C4), but is also available in aluminum, copper, stainless steel and painted versions.
Suitable pressure drop for fresh air is 5-20 Pa and 5-60 Pa for exhaust air.
