4-72 centrifugal fan Industrial induced draft fan 5.5kw air capacity
4-72 centrifugal fan is the earliest fan used in China, but it is also the most common fan used. From high-rise
buildings to underground railways, from boiler air blast to plant air exchange, 4-72 fan can be seen everywhere.
4-72 centrifugal fan as a general factory and large buildings indoor ventilation, can be used as input gas, can
also be used as output gas. Air and other gases that are not spontaneous combustion, harmless to the human
body, and non-corrosive to steel materials.
4-72 fan air volume from 2200~200000m³/ hour, fan diameter Φ250~2000mm, wind pressure 324-3200Pa,
power: 1.1-220kw, medium and low pressure large air volume, there are ordinary type (4-72), anti-corrosion
type (F4-72), explosion-proof type (B4-72), high temperature resistance four specifications. Direct motor
(type A drive), belt drive (B, C, E drive), coupling (D drive), no viscous substances in the gas, the dust and
hard particles contained are not more than 150mg/m3. Gas temperature: not more than 80℃. B4-72 fan
can be used for ventilation of flammable and volatile gases. No viscous substances are allowed in the gas,
and the dust and hard particles contained are not more than 150mg/m. The gas temperature shall not
exceed 80C. The performance of the B4-72 fan and the selected parts and the size of the foundation are
consistent with that of the 4-72 fan, which can be selected according to its sample.
F4-72 centrifugal fan is mainly used for conveying corrosive gases, but the conveyed gas shall not contain
viscous substances, the dust and hard particles contained shall not be greater than 150mg/m3, and the gas
temperature shall not exceed 80°C. The F4-72 centrifugal fan is made of stainless steel, fiberglass or other
corrosion-resistant materials, and its performance and foundation size are the same as that of the 4-72
centrifugal fan.
