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 PD3N133B2E-TZ0 133mm IP55 EC‑AC dual inlet centrifugal blower is a high‑performance solution engineered for central air conditioning units and building ventilation systems. With an exceptional 900 Pa ultra‑high static pressure, this dual inlet blower for HVAC central systems effectively overcomes system resistance from long‑distance duct runs, multiple supply branches, and high‑efficiency filters – ensuring stable airflow at every terminal outlet, making it particularly well‑suited for centralized ventilation systems that demand reliable performance under high‑backpressure conditions.
This IP55 rated double inlet centrifugal fan is equally well‑adapted for fresh air handling and total heat recovery systems – including commercial and residential ventilators, distributed energy recovery ventilators (ERVs) – as well as commercial air purification equipment where combined HEPA/activated carbon filter resistance must be overcome with consistent static pressure. With over 15 years of expertise in EC/AC motor and fan technology, PBM offers OEM customization across multiple dimensions – including custom lead wire configurations, mounting structure adaptations, and optional silencer/filter box accessories – tailored specifically for central air conditioning systems, fresh air ventilation networks, and other specialized applications. Whether you need a 900 Pa dual inlet blower for ERV installations, a corrosion‑treated fan for commercial air purifiers, or a silencer‑equipped centrifugal fan for quiet building ventilation, PBM delivers precision‑engineered solutions backed by full engineering support.
