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 PD3N146B2E-RV1 146mm IP55 EC‑AC dual inlet centrifugal blower is a fully sealed, high‑efficiency fan engineered for demanding ventilation and air treatment applications that require high static pressure and robust dust/water protection – including basement ventilation systems, central fresh air systems, and air purification equipment. Operating at 230V AC rated voltage, 1600 RPM, delivering 750 m³/h airflow and 700 Pa high static pressure, this IP55 rated dual inlet blower for basement ventilation and high static pressure central fresh air fan ensures reliable, energy‑saving performance across long duct runs, complex system layouts, and challenging environmental conditions.
The double‑inlet design delivers approximately 40% higher airflow than single‑inlet configurations at the same rotational speed, while providing more uniform air distribution and reduced vibration – making this high‑airflow dual inlet centrifugal fan for central ventilation an ideal choice for centralized ventilation systems that must overcome high‑backpressure resistance. PBM's OEM customization services cover multiple dimensions – including custom lead wire configurations, upgraded ingress protection (IP) ratings, and optional silencer or filter box accessories – tailored specifically for basement ventilation, fresh air systems, and other specialized applications. Whether you need a 700 Pa dual inlet blower for air purification, a corrosion‑treated fan for underground ventilation, or a silencer‑equipped centrifugal fan for quiet residential fresh air systems, PBM delivers precision‑engineered solutions with full engineering support.
