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 PB3N225B2E-RG0 225mm IP55 EC-AC Backward Curved Centrifugal Fan is designed for cleanroom systems and FFU fan filter units in semiconductor cleanrooms, pharmaceutical workshops, and biological laboratories — overcoming HEPA filter resistance and maintaining laminar flow clean environments in medium-to-high static pressure industrial ventilation applications requiring waterproof and dustproof protection.
Powered by EC motor technology, this backward curved centrifugal fan delivers significant energy savings compared to traditional AC induction motors. The fan supports 0–10V DC / PWM dual-mode stepless speed control input for flexible system integration.
PBM provides more than just standard fan components — we offer complete industrial ventilation solutions throughout the entire R&D process, from demand analysis to mass production.
Choose the PB3N225B2E-RG0 for a high static pressure, low noise, IP55 EC-AC backward curved centrifugal fan for your most demanding cleanroom and FFU applications.
