Industrial centrifugal fan for Siemens motor

The RE22P-2DK.3F.5RMotor is a new centrifugal fan built around a Siemens motor and manufactured by Ziehl-Abegg in Germany. It delivers 490 W of motor power at 400 V and 0.8 A, spinning a 220 mm impeller at 2320 rpm. The unit is designed for industrial heating, cooling and air-quality systems that require a compact external-rotor design.

Airflow ceiling and voltage constraint

Maximum airflow reaches 35000 m3/h, but this figure is only achievable when the supply remains at the rated 400 V and the ducting presents minimal resistance. The fan operates on fixed-speed AC power, so variable-flow applications need external frequency control. Operation outside the specified voltage or current envelope will reduce output and may trip thermal protection.

Direct replacement for legacy Ziehl-Abegg RF22P

This model matches the RF22P-2DK.3F.5R order number 131345, so it fits existing mounting points and wiring without modification. The upgrade is worthwhile when the original fan has reached end of life or when the steel-plate housing shows fatigue. Buyers needing higher static pressure or EC-speed control should evaluate alternative ranges instead.

Questions about this item

Which RE22P-2DK.3F.5RMotor version should I choose for a 400 V supply?

This model runs on 400 V three-phase power, draws 0.8 A and delivers 490 W motor power at 2320 rpm with a 220 mm impeller.

What does the 490 W motor power mean once the fan is installed?

It is the electrical input rating; the impeller can move up to 35000 m³/h of air depending on system resistance and duct design.

What interface or standard governs the speed control and what does it cap?

Speed is adjustable from 0 to 100 % via an analogue or serial interface, allowing full-range control of the 2320 rpm maximum.
