4-72 type centrifugal fan
The 4-72 series features high efficiency, low noise, broad applicability, and a stable pressure curve. It is an ideal choice for indoor ventilation, cooling, and gas recirculation in settings such as mining operations, stadiums, opera houses, basements, hotels of all sizes, restaurants, shopping malls, and major buildings.
The medium being moved consists of air or other non-self-igniting, non-explosive gases that are not harmful to humans. When equipped with an explosion-proof motor, the B4-72 model can be used for ventilating volatile flammable gases.
The transported air must be free of adhesive materials, with dust and particulate content not exceeding 150 mg/m³, and operating temperatures remaining at or below 80°C.
