ID, FD & PA FANS:

Specialised in Boiler Fans for the last 20 years and supplied to most of the Boiler manufacturers throughout the country.

The satisfactory function and performance of a Boiler totally depends upon the Boiler Fan ID, FD and PA for FBC type.

Various design, type and models to suit customer requirement from 1t to 25t capacity.

ID FAN:

Centrifugal / Radial Fan generally, belt-drive or direct through Flexible Coupling with heavy duty Impellers with or without hard facing or with liner plates etc depending upon the fuel handled, erosion and corrosion etc.

Preferred speed up to 1500 and operating temperature up to 280ºC in M.S.Construction, EN-8 Shaft, Roller Bearings, Taper lock Pulleys, Wedge Belts etc for Belt Drive and Tyre Coupling or Special Couplings for Coupling Drive, with heat slinger and heat resistant Aluminium paint, as standard features.

FD FAN:

Centrifugal / Radial Fan with direct drive arrangement in general and flexible coupling drive for higher duty condition at 1420 RPM or 2850 RPM depends upon technical specification. Generally selected for ambient air handling up to 40ºC.

PA FAN:

Centrifugal / Radial Fan generally used for FBC Boilers, operating approximately at 150ºC with direct drive through Flexible Coupling. Invariably low volume and high pressure ranges up to 1100 MM WG maximum with drives 1420 or 2850 through coupling drive.

Optional accessories include,

• Variable Inlet Guidevane
• Outlet Damper
• Inlet / Outlet Bellows
  

to suit customer design.

WIDE Range of Fans in Low Pressure, Medium Pressure and High Pressure classifications.

Arrangements in:

• Direct drive on the motor shaft,
  
• Drive through V Belt & Pulleys &
• Drive through Flexible Coupling.

Based on the operating conditions.

Most of the applications are SISW type and DIDW are used for high volume and low pressure applications like Ventilation, Air Conditioning etc.

Our ranges:

• SISW Low Pressure 100 CMH To 100000 CMH
• SISW Medium Pressure 2000 CMH To 200000 CMH
  
• SISW High Pressure 2000 CMH To 100000 CMH
• DIDW Low Pressure 7500 CMH To 200000 CMH

• Backward curved
• Backward Curved Radial tipped
• Straight Blade & Open wheel
• Paddle Wheel
• Limit load backward curved etc.

• Generally High Pressure Centrifugal type is designed for comparatively small air volume with high efficiency.
• Pressure range upto 1200 mm WG in Single Stage and 1500 mm WG in Multi Stage design with maximum power of 150 KW.
• Widely used for Combustion application pressure ranging from 700 mm WG to 1000 mm WG.
• Range starts from 0.37 KW to 150 KW drive Motor.
• Open wheel design is ideally suited for chips and dust conveying.
• Different Orientation and different arrangements to suit specific requirement and application
