HAN/HAF roof exhaust units are suitable for both industrial and housing ventilation systems. The air is exhausted in a vertical stream to avoid contamination of the air and the nearby roof surface. This roof exhaust unit is so efficient that roof air intakes can be installed very close by. The standard version is made from galvanized steel sheet; non-standard versions in stainless steel sheet, aluminium sheet, or plastic-coated steel sheet (in various colours) are available on request. The roof exhaust unit is topped with a 1/2-inch wire mesh and has an inner deflector flange for protection against snow and drainage of water to the outside of the vent. Above Ø200 mm, the water is drained using a tube of flexible PVC hose.
