The octagonal casing is manufactured from seawater resistant aluminium. The base frame consist of galvanised steel. The impeller with backward-curved blades is also manufactured from galvanised steel.

The fan is equipped with IEC flange electric motor with degree of mechanical protection IP 55, insulation class F. Two speed motors as Dahlander (4-8, 6-12) or with separate windings (6-8, 4-6, 8-12). Motor cooling with fresh air via air duct. Thermal motor protection (PTC) serial built-in. For smaller two speed fans (up to 10A) two speed switch is available as accessories (in this case thermal contact must be ordered; not suitable for PTC or without thermal contact). Connection the fan to the mains in service switch. EMC protected cables, cable glands or service switches on request.

On request the fan can be factory fitted with sound attenuator on outlet as DVVI/120 fan. Sound attenuators are also available as HSDV accessories.
