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.
250mm EC bracket fan from PBM is made especially for cooling electrical control cabinets and big industrial frequency converters. This resistance is readily penetrated by the high static pressure of 716 Pa, which guarantees that vital parts like rectifier modules and IGBTs are sufficiently cooled to avoid overheating and derating. The cooling requirements of two to three frequency converter cabinets linked in parallel may be satisfied by the enormous airflow of 1700 m³/h. Direct installation on the cabinet's top or door is made possible by the bracket design. By dynamically modifying the airflow based on the load rate, the EC motor's 0–10V/PWM speed control allows for energy savings of more than 40%. It is appropriate for industrial settings with a noise level of 75 dB(A). Its 50,000-hour lifespan guarantees continuous output, and its IP44 classification protects against dust. It is the perfect cooling option for servo drive cabinets and high-voltage frequency converters.
