PK3N190B48-RZ0 is a 190mm DC Backward Curved Centrifugal Fan with Support Bracket made especially for therapeutic systems and medical rehabilitation equipment. In clinical settings, equipment for physical therapy and rehabilitation usually has to run constantly for long periods of time. During this time, internal parts including semiconductor lasers, electrotherapy modules, and heating elements continuously produce heat. One clear benefit of the 48 VDC power supply system is its minimal danger of electric shock. It is especially important for guaranteeing the safety of both operators and patients. It can be powered directly from the DC bus of the medical device or from a safety extra-low voltage (SELV) power source. This makes it easier to comply with the IEC 60601 set of medical safety standards and greatly simplifies the electrical arrangement of medical equipment.
PBM specializes in the development and production of superior EC/DC fans and intelligent airflow solutions that support hemodialysis equipment, physical therapy and rehabilitation equipment, and other medical treatment devices. PBM provides a broad variety of customisation services to meet the various demands of medical device makers.
