X-DHS 400E6 roof fan

Art. no.: 5717


Integral thermal contacts

Low sound level

Maintenance-free and reliable

The DHS models have impellers with backward curved blades and external rotor motors. All motors are speed controllable over the voltage. Frequency inverters must have an allpole sine filter. The motors are suspended on effective vibration dampers.

DHS …EZ / EV / ES: 1~ motor with connection for 2-speeds

DHS …E4: 1-speed motor

DHS …DV / DS: 3~ with Y/D-connection for 2-speeds

To protect the motors from overheating the DHS up to size 311 have integral thermal contacts, from size 355 with external leads for connection to a motor protection device.

The casing is made from aluminum and the base frame is made of galvanised steel. Suitable for coastal applications. The impellers up to size 355 are manufactured from polyamide PA6 25GV, from size 400 in aluminium.
