• High efficiency
• Speed-controllable
• Integral thermal contacts
• Excellent sound level
• Extensive range of accessories
• Maintenance-free and reliable

The DVS/DHS/DVSI sileo is well suited for applications requiring high air volumes at medium pressure and very low noise levels. These models have 3D profiled 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 sileo 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 sileo ...E4 / E6 / EZ / EV: 1~ motor

DVS/DHS/DVSI sileo ...DV / DS: 3~ with Y/D-connection for 2-speeds

To protect the motors from overheating the sileo range motors up to size 311 are equipped with integrated thermal contacts with manual reset in acc. with EN 60335-2-80. From size 355 with external leads for connection to a motor protection device. The casing is made from aluminum and the base frame from galvanized steel. Suitable for coastal applications. The impellers of the sileo types are manufactured from high-performance composite material with highly efficient 3D fan blade profile technology.

DVS sileo with vertical outlet
DHS sileo with horizontal outlet
DVSI sileo has a 50 mm mineral wool insulation for lower noise levels.
