R2S175-AB56-01 ebmpapst 230V 175mm AC Centrifugal Fan

Description

The ebmpapst R2S175-AB56-01 is a high-performance 230 V AC centrifugal fan with an impeller size of 175 mm, purpose-built to deliver elite-level thermal cooling in high-resistance airflow paths. This unit features a heavy-duty M2S052-CA external rotor motor capable of sustaining a 51.0 W power input to drive its specialized 7-blade glass-fiber reinforced PA 6 plastic impeller at a consistent 2300 RPM. Engineered specifically for high-efficiency air displacement in compact electronics enclosures, it utilizes a backward-curved design to generate high static pressure without the need for a scroll housing. The mechanical design relies on a precision-shielded dual ball bearing system and a painted black rotor surface to ensure continuous S1 mode operation. Featuring an internal thermal overload protector and a robust Class I protection structure, this fan is a critical component for control cabinet ventilation, laboratory equipment, and industrial cooling where consistent air density and operational safety are mandatory.
