The VHA exhaust hood gives the possibility for an architectally correct ending of air outlet on the roof. The exhaust hood is as standard delivered in galvanised design, but can also be delivered in black powder coating. The hood is equipped with an internal cone, which leads the rain water out over the duct sides.
The air is thrown away with an upward jet. Hence pollution of the air around the hood and dirt on the roof surface around the hood. The exhaust is so effective that quite easily an air intake can be mounted close up, e.g. lamella hood VHL, which designwise suits VHA.
VHA = galvanized
VHA-S = black powder coated
