Features
- Optimised efficiency, low maintenance costs.
- Removable housing cover with clip-locks.
- Inlet and outlet side connection couplings for direct installation in ventilation ducts.
- With sound absorbing rock wool, laminated with silk glass, to meet the increased requirements of especially low noise levels.
Air flow direction
- The airsteam direction is indicated by an arrow marked on the housing.
Motor
- External rotor-capacitor motor.
- Robust motor with ball bearings, maintenance-free.
- The motor's standard rubber mounting prevents vibrations being transferred to the housing.
- Temperature classes B or F.
- IP X4 degree of protection with closed housing cover.
AC motor
- Thermal overload protection as a standard feature.
Three-phase AC motor
- Potential-free terminal connections, which must be connected to an MV 25 protective motor switch or the control circuit of a contactor.
Mounting instructions
