Fans

Fans R2S175-AB56-01 Centrifugal Case Fan 230V 175x69mm

SKU CH-2S87-DFV7K

A 230 V centrifugal case fan with a 175 mm by 69 mm frame, ball bearings and 61 dB noise at 2350 r/min

  • Centrifugal airflow reaches 35000 m³/h for high-volume cooling
  • Backward-curved blades remove the need for a scroll housing
  • 100 % analogue or serial speed control for precise regulation
  • Ball bearing supports continuous 2350 r/min operation at 61 dB
  • UL and CSA recognised components meet safety standards

Centrifugal Case Fan 230V

The Fans R2S175-AB56-01 is a new centrifugal case fan built around an ebmpapst M2S052-CA motor for 230V mains supply. It suits system integrators and industrial PC builders who need direct AC-driven airflow without an external power supply. Its backward-curved blade design pulls air efficiently through restrictive chassis layouts. The unit carries UL and CSA recognition for regulated environments.

Build Integration 175x69mm

The 175mm by 69mm frame mounts directly to standard fan apertures and the forward-bending impeller discharges air without a separate scroll housing. This frees internal volume otherwise occupied by a duct or plenum. The motor spindle runs on ball bearings and the package includes an import ring for secure fastening. Speed is controllable to 100% via analog or serial interface for closed-loop thermal management.

Thermals Noise Power

At 50Hz the fan draws 53W and 0.33A while spinning at 2350r/min; at 60Hz it draws 51W and 0.29A at the same speed. The manufacturer rates acoustic output at 61dB under these conditions. Maximum airflow reaches 35000m3/h, providing forced electronic cooling for dense component stacks. The steel plate construction and external rotor motor keep operating temperatures stable during continuous duty.

Questions about this item

What is the maximum noise level of this R2S175-AB56-01 centrifugal fan at full speed?

The fan produces a noise level of 61 dB during operation at 2350 r/min.

How much power does the fan draw when running continuously on a 230 V supply?

Power consumption is 53 W at 50 Hz and 51 W at 60 Hz, with current draw of 0.33 A and 0.29 A respectively.

Does the R2S175-AB56-01 require a separate speed controller or interface board to operate?

The unit supports 100 % speed control via analog or serial interface, so a compatible controller is needed for variable speed; it runs at fixed speed directly on 230 V mains.
