DVS 710DS
Item number: 36202
Speed-controllable
Integral thermal contacts
Low sound level
Maintenance-free and reliable
The DVS/DHS/DVSI models have impellers with backward curved blades and external rotor motors. All motors are speed controllable over the voltage. For speed controlling of the DVS/DHS/DVSI roof fans with a frequency converter a type with all pole sine filter is needed! The motors are suspended on effective vibration dampers.
DVS/DHS/DVSI …EZ / EV / ES: 1~ motor with connection for 2-speeds
DVS/DHS/DVSI …E4: 1-speed motor
DVS/DHS/DVSI …DV / DS: 3~ with Y/D-connection for 2-speeds
To protect the motors from overheating the DVS/DHS/DVSI 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 from galvanised steel. Suitable for coastal applications. The impellers up to size 355 are manufactured from polyamide PA6 25GV, from size 400 in aluminum.
DVS with outlet vertical
DHS with outlet horizontal
DVSI has a 50 mm mineral wool insulation for low noise level.
