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 PS3N140B48-RP0 220×245×130mm IP55 EC‑DC single inlet centrifugal blower is a fully sealed, safety extra‑low voltage (SELV) high‑static‑pressure fan purpose‑built for demanding decentralized ventilation applications – including distributed fresh air systems, duct booster fans, and small air handling units (AHUs) – where robust dust and water protection are essential. Operating at 48V DC rated voltage, 1600 RPM, delivering 500 m³/h airflow and 850 Pa high static pressure, this IP55 rated SELV centrifugal blower for fresh air systems and compact duct booster fan with 850 Pa ensures reliable, energy‑saving performance across a wide range of building ventilation scenarios.
PBM provides full engineering support from demand analysis and selection evaluation through prototype testing to mass production, with technical assistance at every stage. Our OEM customization services cover multiple dimensions – including custom lead wire configurations, corrosion‑resistant surface treatments, and optional silencer or filter box accessories – tailored specifically for decentralized ventilation systems, small AHUs, and other specialized applications. Whether you need a 48V high static pressure fan for duct boosting, a corrosion‑treated blower for residential exhaust, or a silencer‑equipped centrifugal fan for quiet office ventilation, PBM delivers precision‑engineered solutions for your building ventilation requirements.
