Features
- Installation in square ventilation channels.
- Galvanised housing.
- With sound absorbing lining to meet the increased requirements for especially low noise levels.
- Low energy consumption thanks to EC technology.
- Reduced space requirement due to compact dimensions.
- Flange profiles fitted on the inlet and outlet sides.
- Centrifugal impellers with backward curved blades made of galvanised steel (DN 22-DN 35) or UV-stabilised and glass fibre reinforced, polypropylene (PP) (DN 50-DN 56).
- Impeller rests on the motor shaft and is directly driven.
- Statically and dynamically balanced in accordance with DIN ISO 21940-11, balance quality G6,3.
- High degree of protection IP 54.
- Use ELP flexible coupling to prevent transmission of vibrations onto the channel system.
Air flow direction
- Air flow and rotational direction are marked by arrows on the fan housing.
- Clockwise direction of rotation viewed from the intake side.
Motor
- Motor designed for continuous operation.
- Robust EC motor with ball bearings, maintenance-free.
- Speed can be specified in continuously variable manner in control mode using a 0 - 10 V signal or potentiometer.
- Thermal motor protection as standard feature.
- Integrated motor protection routed via alarm relay.
- Status display via LED (DN 50-DN 56).
- Modbus RTU interface.
- Integrated 24 V voltage source for optional accessories.
Installation instructions
- Installation in horizontal and vertical position possible.
Electrical connection
- Depending on model, is connected at terminal box or led-out cable.
- 50 Hz power frequency.
