EC Motor and EC Fan
PANKA FanPengke PLFE Centrifugal Exhaust Fan (EC/AC)
The PLFE series is PANKA's centrifugal exhaust fan designed for oil fume and high-temperature flue gas applications. Building on the PLF shell-less design, it features an easy-clean structure that allows rapid disassembly of the impeller and housing to prevent oil buildup, which can reduce airflow and cause dynamic imbalance. 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 225mm to 1250mm, with material options including aluminum alloy, carbon steel, and stainless steel. The product holds fire safety certification and ATEX explosion-proof certification. It is suitable for commercial kitchen exhaust, canteen ventilation, and fire smoke extraction systems. The EC version supports stepless speed control, automatically adjusting exhaust volume based on kitchen load and flue gas concentration to reduce energy consumption.
