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 PS3N140B24-RP0 220×245×130mm IP55 EC‑DC single inlet centrifugal blower is a fully sealed, safety extra‑low voltage (SELV) high‑static‑pressure fan engineered 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 24V DC rated voltage, 1600 RPM, delivering 500 m³/h airflow and 850 Pa high static pressure, this IP55 rated SELV centrifugal blower for decentralized fresh air systems and compact duct booster fan with 850 Pa ensures reliable, energy‑saving performance with an acoustic output of just 64 dB(A), striking a practical balance between powerful airflow and user‑friendly operation in ventilation equipment and industrial environments.
The blower supports 0‑10V DC / PWM dual‑mode stepless speed control input, enabling system integrators to dynamically adjust airflow based on real‑time terminal static pressure and air quality sensor feedback in decentralized ventilation networks. This enables demand‑controlled ventilation (DCV) , eliminating the energy waste associated with fixed‑speed fans and significantly improving overall system efficiency. Whether you need a quiet 24V blower for classroom ventilation, a high static pressure fan for duct boosting, or a custom SELV centrifugal fan for small AHU applications, PBM delivers precision‑engineered solutions backed by full engineering support.
