FOCUS ON EC FAN ONLY
190mm DC Backward Curved Centrifugal Fan made especially for Ventilation of Operating Table and Operating Room is the PB3N190B24M. Clean operating room air conditioning systems (clean ICU), operating room fan filter units (FFU), local air supply devices for operating tables, and pressurization units for dynamic and static supply/return air ducts in operating rooms are some of the major scenarios in which this DC fan is typically used in medical clean environments. Compared to conventional tiny axial flow fans or forward centrifugal fans, it saves 30% to 50% on energy thanks to its high-efficiency DC brushless motor. The PB3N190B24M satisfies the cleanliness classification standards of the international standard ISO 14644-1 (Cleanroom and Related Controlled Environments) and successfully satisfies the fundamental operating room requirements of "high static pressure, extended lifespan, and low noise. "It is the perfect core power source for resolving airflow resistance problems in different ventilation systems in operating rooms and other hygienic medical settings.
PBM concentrates on the use of premium EC/DC fans in the purifying industries of industry and medicine. In addition to enhancing fan performance, it aims to offer surgical cleanroom system integrators specialized OEM/ODM services, such as fan outlet installation angle selection, protection upgrades, extra silencers/silencer boxes, and installation flange brackets.
