  • 690 W and 350 W power ratings match load demands
  • ZIEHL-ABEGG engineering ensures reliable centrifugal airflow

Industrial centrifugal cooling fan

This 450 mm centrifugal case fan from ZIEHL-ABEGG is built for industrial and commercial cooling tasks. It suits engineers and facility managers who need reliable airflow in medical equipment, rail vehicles, drive systems, hotel installations, industrial cleaning machines, electronic enclosures, new-energy vehicles or supermarket refrigeration.

Dual-speed sustained operation

The motor delivers two fixed power levels of 690 W and 350 W at 400 V, drawing 1.3 A and 0.66 A respectively. Corresponding speeds are 1210 r/min and 830 r/min, allowing the fan to maintain steady airflow under continuous load rather than only in short bursts.

Verify voltage and mounting before ordering

Confirm that your system provides a 400 V three-phase supply and can accommodate the 450 mm blade diameter. Custom processing is available, so discuss any special mounting or control requirements with your technical team prior to purchase.

Questions about this item

How much power does the 450 mm RH45M-VDK.4F.1R draw when running continuously at 400 V?

The motor is rated at 690 W on high speed and 350 W on low speed, with corresponding currents of 1.3 A and 0.66 A at 400 V.

What power source and control equipment are required to operate this centrifugal fan?

A three-phase 400 V supply and a compatible frequency converter are needed to drive the ZIEHL-ABEGG motor.

Will the 1210 rpm high-speed setting overwhelm older 120 mm or 133 mm case fans in the same chassis?

This 450 mm centrifugal unit moves significantly more air at 1210 rpm than smaller axial fans, so separate fan curves or speed control should be used to balance airflow.
