4-72 centrifugal fan can be used as indoor ventilator in general factories and large buildings, it deliver air and other gas which is harmless, non-spontaneous and non-corrosion. it is harmless to human body and it has no steel non-corrosive gases. B4-72 type ventilation fan can be used for ventilation of the flammable volatile gas.Viscous material is not allowed in the gas.the dust and hard particles contained can not be more than 150 mg/m3. Gas temperature shall not exceed 80u2103. In order to facilitate users to install and use the fan, we adopt the latest design for 2.8 A - 6 A fan which use the overall frame structure, that means blower and motor are connected into whole.
1. high flow rate, high efficiency, low noise, light vibration,facilitate to install ,etc
2.Widely used as indoor ventilator in general factories and large buildings,etc
3. Large logistics distribution network,high efficienct pre-sale,sale technical and maintenance service.
4. Lastest designed 2.8A-6A fan use the overall frame stucture,that means blower and motor are connected into whole.
5.The gas delivered by the series of fan cannot have sticky matters, and is noncorrosive, non-flammable and non-explosive.
We can design and manufacture 4-72series with
1.Vibration reduction stage posture fan.
2.Double suction fan.
3.High temperature 4-72 series fan.
4.Corrosion resistance 4-72 series fan.
