EC Motor and EC Fan
PANKA FanPengke PLF Centrifugal Fan (EC/AC)
The PLF series features PANKA's plug centrifugal fans, which use a direct-coupled motor design with the impeller mounted directly on the motor shaft. By removing the traditional scroll casing and belt drive, this design delivers high overall efficiency and minimal maintenance requirements. Key performance specs include a maximum airflow of 120000m³/h, max pressure of 4500Pa, peak static efficiency of 79%, and peak total efficiency of 83%. Impeller diameters range from 250mm to 1250mm and are available in aluminum alloy, carbon steel, or stainless steel to handle general ventilation, dusty media, and corrosive environments. The EC version uses an electronically commutated motor, supporting 0-10V/PWM stepless speed control and intelligent group control for superior part-load efficiency. The AC version is compatible with both line-frequency and variable frequency drives, simplifying retrofits for existing systems. Typical applications include large industrial air handling units, packaged air conditioning units, and process supply/exhaust systems. Products are AMCA and CE certified.
