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.
400mm DC backward-curved centrifugal fan made especially for medical purification systems and air handling units (AHUs) is the PB3N400B24M. The brushless DC motor's low self-heating properties guarantee that the fan produces less heat when operating in cleanroom environments with consistent humidity and temperature. Because of this, very little waste heat is emitted into the airflow, preventing the AHU from experiencing an additional thermal stress. This greatly preserves exact control over the supply air temperature of the AHU while also avoiding needless energy expenditure related to adjusting for thermal interference.
PBM is an expert in the development and production of superior EC/DC fans and intelligent airflow solutions. PBM provides a broad range of customized services to satisfy the various demands of producers of commercial HVAC equipment, medical purification units, and modular air handling systems.
