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 PS3N140B2E-RZ0 140mm IP55 EC‑AC single inlet centrifugal blower is a compact, high‑static‑pressure fan purpose‑built for decentralized ventilation systems – including office partition ventilation, independent classroom fresh air supply, residential kitchen and bathroom exhaust, distributed total heat exchangers (ERVs), and standalone silent supply fans – as well as small air handling units (AHUs) and duct booster fans that require overcoming long duct runs and high‑efficiency filter resistance. With its fully sealed IP55 construction and EC‑AC motor technology, this blower delivers reliable, energy‑saving performance in space‑constrained building ventilation applications where consistent static pressure is critical to system performance.
Operating at 230V AC rated voltage, this IP55 centrifugal blower for decentralized ventilation and compact duct booster fan for small AHUs ensures stable airflow even under variable load conditions. PBM's OEM customization services cover multiple dimensions – including custom lead wire configurations, corrosion‑resistant surface treatments, and optional silencer/filter box accessories – tailored specifically for decentralized ventilation systems, small AHUs, and other specialized applications. Whether you need a high static pressure fan for classroom ERV, a corrosion‑treated blower for residential exhaust, or a silencer‑equipped centrifugal fan for quiet office ventilation, PBM delivers precision‑engineered solutions for your building ventilation needs.
