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 310mm ec backward curved centrifugal fan from PBM is made especially for large-scale fresh air systems and air purification apparatus. It readily overcomes the resistance of HEPA filters and long-distance ducting by delivering an airflow of up to 2690 m³/h and a static pressure of 660 Pa using a 230V EC motor, ensuring clean air is equally disseminated to all regions. With a power consumption of around 350W, noise levels of ≤78 dB(A), and IP44 protection, the device may be installed in equipment rooms or ceilings. With an air quality sensor, it can run on demand and supports 0–10V/PWM speed control. It is appropriate for fresh air units and big air purifiers in shopping centers, hospitals, schools, and other comparable settings because of its 50,000-hour lifespan, which guarantees dependable ventilation in public spaces.
