Fans RG90-18/56 Centrifugal Case Fan 230V 22W 1900/2200 RPM

SKU CH-P77V-C9XHC MPN RG90-18/56

Compact centrifugal fan moves air at right angles with high static pressure for space-constrained applications

  • Compact centrifugal design fits tight spaces
  • High static pressure moves air through dense obstacles
  • 230 V AC operation with 22 W motor power
  • Dual-speed 1900/2200 RPM with locked-rotor protection
  • UL, CSA and VDE safety certifications

Centrifugal Fan for Space-Constrained Cases

The Fans RG90-18/56 is a compact centrifugal case fan built for installations where airflow must exit at a right angle to the intake. It operates on 230 V AC at 50/60 Hz and draws 22 W with a current of 1.20/1.22 A. The motor runs at 1900/2200 RPM and uses ball bearings for durability. UL, CSA and VDE recognitions confirm compliance with recognised safety standards.

Suitable for Industrial and Custom Cooling Builds

This fan suits builders who need high static pressure in a flat-package radial design for forced electronic cooling. It offers 100 % speed control via analog or serial interface and includes locked-rotor protection. Buyers requiring standard axial airflow, low-voltage DC operation or PWM motherboard headers should look at other solutions because this unit is a mains-powered centrifugal blower.

High Static Pressure with 35000 m³/h Peak Airflow

The blower delivers airflow up to 35000 m³/h, providing strong cooling headroom for dense component stacks or restricted ventilation paths. Its compact external-rotor motor and sturdy steel plate keep the profile slim for tight enclosures. At maximum load the 22 W motor reaches its thermal and pressure limits, so systems demanding higher volume or lower noise at equivalent pressure will need a larger or parallel fan arrangement.

Questions about this item

What power supply voltage and frequency does the 230 V 22 W motor require?

The motor runs on 230 V AC at 50 or 60 Hz, drawing 1.20 A at 50 Hz and 1.22 A at 60 Hz.

Can the fan be speed-controlled from an existing analogue or serial interface in my system?

Yes, the unit supports 100 % speed control via analogue or serial interface for integration with existing controllers.

How do I verify the fan is delivering its rated airflow after installation?

Measure the exhaust flow; the fan is rated for up to 35 000 m³/h at the specified 1 900 / 2 200 min⁻¹ speeds.
