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 Fans with Support Bracket made especially for medical imaging equipment is the PK3N225B48-RG0. Its low noise level of only 68 dB(A) and the intrinsically low electromagnetic interference of DC motors enable seamless integration into the MRI system's gradient amplifier and RF power amplifier cooling units, avoiding the risks of magnetic field interference associated with traditional AC fans. Additionally, it is appropriate for applications like orthopedic intraoperative navigation systems and mobile C-arms that have very high heat dissipation needs in small places.
PPM specializes in thorough ODM and mass production delivery of medical cooling systems, as well as the development and production of superior EC/DC fans and intelligent airflow solutions. It facilitates device health management (PHM) systems and speed signal output (FG) for simple system integration, allowing remote monitoring and defect warning throughout the whole lifespan.
