The assembly consists of a mounting base, fan, base and shut-off flap. The shut-off damper is equipped with a 24 V DC actuator as standard. Alternatively, a power supply for 230 V AC can be fitted. The servo drives can be supplied in a version with signals from limit switches (KS). THGT fans are integrated in the assemblies according to power and size from DN 400 to DN 1120.
- double-skinned mounting base made of galvanized steel sheet with 100 mm thick thermal insulation
- mounting base is made of steel with hot-dip galvanized surface with holes for supply cables to the fan and to the damper actuator
- the damper has a frame made of Al profiles and sheets, EPDM sealing, filling of polycarbonate plates of opal colour 20 mm thick with U = 1,6 W/(m2K) or on request 1,2 W/(m2K)
- the damper actuator must not be permanently energized
- consult the wiring of the electrically operated damper and motor
- the damper can be supplemented with a 230 V AC / 24 V DC power supply allowing the damper actuator to be controlled by 230 V AC, The fan assembly is designed for forced heat and smoke extraction in case of fire and is tested according to EN 12101-3:2015 with classifications F400(120), F300(60) and F200(120)
- the fan assisted assembly can also be used for service ventilation, consult for application
