FOCUS ON EC FAN ONLY
PBM FOCUS ON EC FAN ONLY. Certificate: CE,UL,ROHS; Supply Ability: 100,000 pcs per year; MOQ: 1~100 pcs based on EXW price; 100 pcs above based on FOB price.
The PB3N133B2E-FZ0 133mm IP55 EC-AC Backward Curved Centrifugal Fan is powered by advanced EC motor (electronically commutated brushless motor) technology, delivering significant energy savings compared to traditional AC induction motors across all operating conditions, with input power of just 30 W and current of 0.2 A.
What sets the FZ0 version apart is its industry-leading acoustic performance — with实测 operating noise of only 64 dB(A) , significantly lower than the 75–80 dB(A) noise levels commonly found in medical rehabilitation fans with metal housings or conventional rotors. This makes the FZ0 particularly well-suited for acoustically sensitive healthcare environments such as rehabilitation hospitals, community rehabilitation centers, and elderly care facilities.
PBM ensures that our backward curved centrifugal fans strictly comply with international safety standards. We provide more than just standard fans — we offer complete industrial ventilation solutions throughout the entire R&D process.
Choose the PB3N133B2E-FZ0 for a low-noise, high static pressure, IP55 EC-AC backward curved centrifugal fan for your most demanding medical and healthcare applications.
