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.
Specifically made for Incubator for premature infants (such as medical infant incubators, neonatal incubators, premature infant thermometers, infant transport incubators, NICU incubators, and other neonatal medical warming and care equipment), the PB3N175B12H is a 175mm DC Backward Curved Centrifugal Fan. Its IP44 protection rating (which may be upgraded to IP55) and operational temperature range of -25°C to 60°C enable reliable operation in the incubator's long-term hot, humid environment. The NMB ball bearing system dramatically lowers the frequency and overall cost of medical maintenance because to its incredibly long maintenance-free life of 50,000 hours. From a hardware standpoint, the motor has safety features including stall protection, polarity protection, and automatic restart, guaranteeing complete newborn safety.
PBM supports the development of medical newborn incubators, transport incubators, and NICU care equipment by concentrating on the research, development, and production of superior EC/DC fans and intelligent airflow solutions. PBM is dedicated to offering clients across the world adaptable and effective one-stop OEM customization services.
