PANKA FanPengke PLFB Centrifugal Supply and Exhaust Fan Unit (EC/AC)
The PLFB series is PANKA's centrifugal supply and exhaust fan unit, integrating the centrifugal fan, motor, and housing into a single assembly. Its quick-release housing design allows for rapid removal of the access door and impeller module, simplifying on-site maintenance and cleaning. Performance highlights include a maximum airflow of 100000m³/h, maximum pressure of 4500Pa, peak static efficiency of 79%, and peak total efficiency of 83%. Impeller diameters range from 250mm to 1250mm, with material options including aluminum alloy, composite materials, carbon steel, and stainless steel. The housing features integrated inlet and outlet flanges for direct connection to duct systems, eliminating the need for on-site fan room construction and vibration isolation foundations. The EC version supports stepless speed control and centralized group management, making it ideal for ducted supply/exhaust applications, underground mechanical room ventilation, and building fresh air and exhaust systems.
