SKU CH-22TZ-NQSE6

Centrifugal case fan moves 1195 m³/h at 230 V AC with backward-curved blades and included capacitor

  • High airflow of 1195 m³/h for effective cooling
  • Runs on standard 230 V AC mains power
  • Backward-curved blades boost efficiency and reduce noise
  • Wide -25 °C to 70 °C operating range
  • Includes capacitor and inlet ring for quick installation

Product identity

This is an ebm-papst R2E225 series centrifugal case fan designed for 230 V AC mains operation. It delivers 1195 m³/h airflow through a 225 mm diameter, 99 mm deep housing with backward-curved blades and an integrated capacitor. The unit runs at 2500–2600 min⁻¹ drawing 155–210 W depending on frequency.

Who it suits and who it does not

It suits industrial enclosures, rack cabinets and server chassis that can accept direct AC power and have space for the 225 mm frame. It is not for builds powered from motherboard 12 V DC headers or small-form-factor cases that cannot fit the dimensions. Buyers needing variable-speed PWM control from a standard PC header should look elsewhere.

Deciding specification

The defining specification is the 230 V AC single-phase supply at 50–60 Hz. Without a mains-voltage feed and the required 3.5 µF capacitor the fan will not operate, so confirm your system provides AC power before ordering.

Questions about this item

Should I choose the R2E225-RA92-23 or the R2E225-RA92-48 version?

The 23 model runs at 50 Hz with 155 W power input and 0.68 A current draw, while the 48 model runs at 60 Hz with 210 W and 0.92 A; both share 230 V AC and 3.5 µF capacitor.

What does the 1195 m³/h airflow figure mean once the fan is installed?

It delivers up to 1195 cubic metres per hour at zero back pressure, with a speed range of 2500 to 2600 min⁻¹ depending on the frequency supplied.

What interface or standard applies to this 230 V AC centrifugal fan?

It carries CE approval, uses a single-phase 230 V AC supply at 50 or 60 Hz, and includes a 3.5 µF 450 VDB capacitor for motor operation.
