PANKA Fan

Pengke PLFH External Rotor Centrifugal Fan

The PLFH series is a PANKA centrifugal fan with an external rotor motor. Its integrated motor and impeller design features a compact axial profile, minimizing installation space. The modular architecture allows flexible arrangement to suit various duct configurations. Key performance metrics include a maximum airflow of 7000 m³/h, a maximum pressure of 1000Pa, and a peak efficiency of 65%. Impeller diameters range from 190 mm to 450 mm. Available materials include galvanized steel, aluminum alloy, and composite options, selectable based on media cleanliness and corrosion resistance requirements. Typical applications include small HVAC systems, air purification units, and cleanroom FFU (Fan Filter Unit) modules. It is also ideal for internal equipment cooling, cabinet ventilation, and small-scale fresh air exchange. CE certified; AMCA performance certification available upon request.
