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-RV0 146mm IP55 EC‑AC dual inlet centrifugal blower is a high‑efficiency AC‑driven fan engineered for demanding ventilation applications that require high airflow and robust environmental protection – including underground and basement space ventilation systems that rely on 620 Pa static pressure to overcome resistance from long duct runs, elbows, fire dampers, and plenum boxes, ensuring stable air delivery at every terminal outlet; as well as fresh air handling and total heat recovery systems (commercial and residential ventilators, distributed ERVs), and ventilation and purification equipment.
The double‑inlet structure delivers approximately 40% higher airflow than single‑inlet designs at the same rotational speed, while providing more uniform air distribution and reduced vibration – making it an ideal choice for centralized ventilation systems that must overcome high‑backpressure resistance. With over 15 years of dedicated expertise in EC/AC motor and fan technology, PBM ensures that the PD3N146B2E-RV0 strictly complies with CE, UL, and RoHS international safety standards. Whether you need a 620 Pa dual inlet blower for basement ventilation, a high‑airflow ERV fan with double‑inlet design, or a certified EC‑AC centrifugal blower for building ventilation networks, PBM delivers precision‑engineered solutions backed by full engineering support.
