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.
The PB3N175B48-RZ0 175mm IP55 EC-DC Backward Curved Centrifugal Fan is specifically engineered for medical rehabilitation and physiotherapy equipment cooling systems, including rehabilitation therapy devices and physical therapy equipment that require long-term continuous operation. With 650 Pa high static pressure, this fan reliably overcomes resistance from multi-layer heatsink arrays and filter screens inside the equipment, ensuring core components operate within optimal temperature ranges.
Designed for demanding industrial ventilation scenarios requiring high static pressure with waterproof and dustproof protection, this backward curved centrifugal fan delivers fully sealed, high-efficiency, energy-saving performance. The entire unit achieves an IP55 protection rating — fully dust-tight and resistant to sustained low-pressure water jets — ensuring reliable long-term operation in environments with stringent cleanliness and reliability requirements, such as medical equipment rooms and outdoor enclosures, while also facilitating regular cleaning and maintenance.
