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.
225mm DC Centrifugal Fan with Support Bracket made especially for medical imaging equipment is the PK3N225B48-TG0. Compared to traditional AC fans of the same size, it saves 30% to 50% on energy thanks to its high-efficiency DC brushless motor. Extremely low vibration, extended lifetime, and ultra-high static pressure are all balanced. Its 960 Pa ultra-high static pressure output, which is widely used in the rack and X-ray tube cooling systems of CT computed tomography scanners, efficiently overcomes the cumulative resistance of several layers of heat sink arrays, dust filters, and intricate annular airflow channels within the rack, guaranteeing that the X-ray tube and detector remain within a safe operating temperature range, greatly extending the X-ray tube's lifespan and lowering hospital equipment maintenance costs.
PPM specializes in thorough ODM and bulk delivery of medical cooling systems, as well as the development and production of superior EC/DC fans and intelligent airflow solutions. In addition to making fans, PBM offers cooling system solutions for medical imaging equipment.
