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-MZ0 209×219×270mm IP55 EC‑AC dual inlet centrifugal blower is a fully sealed, high‑efficiency fan engineered for a wide range of HVAC applications – including air conditioning, ventilation, refrigeration, and air purification – where reliable performance under demanding conditions is essential. Operating at 230V AC rated voltage, 1850 RPM, delivering an impressive 1300 m³/h high‑capacity airflow and 850 Pa high static pressure, this IP55 rated dual inlet blower for HVAC systems and high airflow double inlet fan for air purification ensures consistent, energy‑saving operation even in the most challenging central system configurations.
With a full IP55 protection rating – completely dust‑tight and resistant to sustained low‑pressure water jets – and a high‑strength cold‑rolled steel impeller, this heavy‑duty dual inlet centrifugal fan for equipment rooms delivers long‑term stability in demanding environments such as air conditioning plant rooms and mechanical equipment spaces. PBM's OEM customization services cover multiple dimensions – including custom lead wire configurations, upgraded ingress protection (IP) ratings, corrosion‑resistant surface treatments, and optional silencer/filter box accessories – tailored specifically for HVAC systems, ventilation and purification equipment, and other specialized applications. Whether you need a 1300 m³/h dual inlet blower for commercial air conditioning, a corrosion‑treated fan for refrigeration systems, or a silencer‑equipped centrifugal blower for quiet building ventilation, PBM delivers precision‑engineered solutions with full engineering support from prototype to production.
