Technical specifications
Datasheet (PDF) - download| Product attribute | Value |
|---|---|
| Airflow at 0 Pa | 353 m³/h |
| Speed | 3400 rpm |
| Power | 42W |
| Voltage | 48 V DC VAC |
| Motor frame | The unit is a motorized impeller designed for mounting on a 180 x 180 mm base plate. It is secured with M4 screws, with a maximum depth of 8 mm. Airflow and noise level depend on the installation conditions, and the specified values apply to defined measurement conditions. The unit is supplied in bulk, with 32 units per standard package. |
| Casing | plastic, centrifugal motorized impeller ø175 x 69 mm |
| Impeller | The fan impeller is a backward-curved centrifugal impeller with a diameter of 175 mm and a depth of 69 mm. It is made of glass-fiber reinforced plastic for high mechanical stability and light weight. The airflow is axial in and radial out. The measured airflow is 353 m³/h at free flow (curve 1). The measurements were performed with the fan mounted on a base plate 180 x 180 mm with an inlet opening of ø 125.5 mm. |
| Bearing type | ball bearing |
| Motor code | RER175-42/18/2TDMLP |
| Rotation direction | clockwise as viewed from the rotor side |
| Motor type | The motor is a three-phase EC motor with fully integrated electronic commutation. The voltage range is 36–65 V DC with a nominal voltage of 48 V DC. The motor supports PWM control as standard, with a speed signal and control input included. The speed can be regulated from 800 rpm at 7% PWM up to a maximum of 3400 rpm at over 90% PWM. At 0% PWM, the motor is stationary, and if the control line is interrupted, the motor runs at maximum speed. |
