Centrifugal Blowers are used for high pressure applications in combustion and low pressure applications in Heating Ventilation and Air Conditioning (HVAC). These include firing in burners, fume exhaustion, providing dilution air in chimneys and providing cooling air, ventilation, suction etc. The impeller is carefully balanced statically and dynamically to obtain a vibration free running.
Direct Drive High Pressure Blower
For directly driven blowers, the impeller is directly mounted on the motor shaft. These are high speed high pressure blowers used for combustion of solid, liquid and gaseous fuels, for pneumatic cleaning and conveying, for creating artificial waves in water parks / wave pools etc.
These blowers are also available in double and triple stage design for developing extra high pressure.
Pressure – up to 3000 mm SWG
Volume – up to 15000 m3 / hr
Direct Drive Low Pressure Blower
These are high volume low pressure blowers suitable up to only 100 °C. These are used for providing cooling air, dilution, ejection, ventilation and air circulation, etc.
Pressure – up to 300 mm SWG
Volume – up to 18,500 m3 / hr
Indirect Drive Blower
Indirectly driven blowers are operated through a flexible coupling or a V-belt drive. These are suitable for high temperature applications (>100 °C) with low pressure and high discharge volume. The design allows easy access to the impeller without disturbing the ducting at the suction or exhaust. Air / water cooling arrangements can be provided for the protection and long life of bearings.
Pressure – starting from 100 mm SWG
Volume – up to 1,00,000 m3 / hr
