Grain Drying Centrifugal Blower Fan Hot Air 80℃ Centrifugal Exhaust Blower

Grain Drying Centrifugal Blower Fan Hot Air 80℃ High Efficiency

This series of centrifugal fans has high efficiency, low noise and stable performance curve. Mainly used for indoor ventilation, dehumidification and dust removal, etc. in factories and mines, stadiums, opera houses, basements, large and small hotels, restaurants, shopping malls and large buildings. It can also be used as a gas recycler with other types of machinery.

4-72 series centrifugal ventilators is capable of blowing air, ocean air containing salt vapour, and corrosive air which contains oil vapour and a small quantity of acid steam generated by the natural evaporation of the batteries. So it can be used for ventilation of various machinery room and each compartment of boats and ships as well as other likes spaces.
We can supply the fan matching damper seat or steel bracket.

High Efficiency

1.Venturi inlet shall match the front disc precisely to avoid turbulent flow and air leakages, so that the air flows more smoothly to improve aerodynamic performance.

2.Optimized design repeatedly of CFD flow field simulation to ensure aerodynamic performance complied with the flow field characteristics.

3.Excellent aerodynamic performance, the maximum efficiency is up to 81%.

Advantage

1. High strength wear-resistant impeller anti-leaking bearing box.
2. Transmission part group consists of main shaft, bearing box, rolling bearing, pulley or coupling, etc.
3. Inlet and outlet flexible joints, dampers.
4. Inlet valve, bearing temperature and vibration dective sensers, impeller cleaning nozzle are optional.
5. With single suction, backward of monoblock type blades impeller have good aerodynamic performance and reliability of smooth operation.
