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 PS3N160B48-TZ0 220×245×130mm IP55 EC‑DC single inlet centrifugal blower is a fully sealed, safety extra‑low voltage (SELV) high‑performance fan engineered for demanding ventilation applications requiring ultra‑high static pressure and robust dust/water protection – including ducted air conditioners, central air conditioning terminal systems, and fresh air handling units. Operating at 48V DC rated voltage, 2000 RPM, delivering 600 m³/h airflow and an exceptional 900 Pa ultra‑high static pressure, this IP55 rated SELV centrifugal blower for ducted AC systems and high static pressure fan for central HVAC terminals ensures reliable, energy‑saving performance even across long duct runs and complex system resistance profiles, with acoustic output limited to 69 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 supply air demand in ducted air conditioning networks. This demand‑controlled ventilation (DCV) capability eliminates the energy waste inherent in fixed‑speed fans, significantly reducing operational costs while maintaining precise environmental control. Whether you need a 48V high static pressure blower for VRF systems, a speed‑controllable fan for ERV installations, or a custom SELV centrifugal fan for commercial air conditioning terminals, PBM delivers precision‑engineered solutions backed by full engineering support.
