- Speed-controllable
- 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.
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, powder-coated. Suitable for coastal applications.
The impellers up to size 355 are manufactured from polyamide
PA6 25GV, from size 400 in Aluminium.

The roof filter fan, with natural or forced ventilation, facilitates excellent internal air flow, removing dissipated heat from the cabinet.
The “TP” series in plastic construction, features reduced dimensions and a standard connection by terminal block.

-Very low noise
-Minimal depth in enclosure
-High through-flow air volume
-Uniform air circulation
-High reliability
-Time-saving installation
Roof filter fans and roof exit filters find use in enclosures, from which warm air has to be diverted due to increased heat development.
The ready-to-connect, low-noise roof filter fan, which houses four axial fans, is used to expel warm air from within the enclosure which has been generated by the stray power of the components.
The roof exit filter provides passive ventilation.
