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.
This PW3N300B2E-TZ0 IP55 EC-AC axial fan is a high-performance ventilation solution engineered for double-skin ventilation curtain wall systems – leveraging the stack effect and greenhouse effect principles as the core active mechanical ventilation unit within the air cavity. Compared to traditional single-skin curtain walls, this system saves 42–52% of heating energy and 38–60% of cooling energy – making it an ideal choice for energy-efficient green building designs. Beyond curtain wall applications, this fan is also widely used for industrial plant ventilation (removing heat, exhaust gases, and dust to improve working conditions) and commercial/industrial HVAC fresh air systems, total heat exchangers, and AHU air handling units.
Powered by a 230V AC motor with advanced EC technology, this fan delivers significant energy savings compared to traditional AC induction motors. The fully sealed IP55-rated construction ensures reliable performance against dust and water jets – ideal for outdoor and demanding environments.
Customization for Curtain Wall Projects: Recognizing the unique installation requirements of ventilation curtain wall systems, PBM offers custom fan housing shapes and flange adaptations based on structural drawings and actual beam clearance dimensions – ensuring precise fit and optimal airflow performance for each project. Our technical sales team provides full engineering support from design validation to mass production delivery, ensuring seamless integration and project success.
