The RER133-41/14/2TDMP from EBM-Papst is a compact DC centrifugal fan with backward-curved blades in a blower design. The fan measures 133×133×91 mm and delivers up to 460 m³/h at free air flow – driven by an EC motor with sensorless commutation. It is ideal for integration into control cabinets, medical equipment, and industrial systems where high performance and flexible control are required.
Thanks to PWM control (1–20 kHz), the speed can be continuously adjusted between 0 and 100%, making the RER133-41/14/2TDMP an energy-efficient choice for applications with varying airflow needs. The fan is intended for installation in protected areas with a controlled environment.
