We manufacture a wide range of exhaust fans that are high in performance and are low power consuming. We offer our products in industrial grey stove enamelled finish. Our range of exhaust fans are offered with different kinds of parts like :

Motor

• Totally enclosed dust proof fan motor.
• Pressure die cast aluminium rotor mounted on pre lubricated double ball bearings.
• Silent operation.
• Continuously rated motor operating on 230 volts single phase or 440 volts three phase and 50 Hz A.C. supply.
• Single phase motors are capacitor start and run, three phase motors are conventionally wound and star connected.

Impeller

• Four curved blades of deep draw sheet steel fitted on a robust aluminum die cast hub, mild steel shank in case of G.E.Series & G.P.Series models respectively.
• The impeller assembly is balanced dynamically to minimize vibrations.
• The broad blades are angled for maximum air flow at low sound level.

Frame

• The frame is fabricated from sheet steel.
• The fan is suspended from the frame on rubber mounting which dampen any residual vibration.

Finish

• Industrial Grey Stove Enameled Finish.

Optional Features

• Louvre Shutters.
  These are opened by the drought of the fan and are closed by gravity when the fan is switched off.
• Acid Alkali Resistant Treatment.
  Fans are specially coated for applications where the fan is exposed to corrosive atmosphere.
• I.P. 55 Degree protection.
  Fans are specially constructed for outdoor application where the fan is exposed to rain and dust.

We manufacture a wide range of air circulator (wall mounting, pedestal type) which are available in the following specifications:

Motor

• Pressure die cast aluminium rotor mounted on prelubricated double ball bearings.
• Silent Operation
• Continuously rated motor operating on 230 volts single phase or 440 volts three phase and 50 Hz A.C. supply.
• Single phase motors are capacitor start and run, three phase motors are conventionally wound and star connected.

Propeller

• Cast out of Al. alloy, it is duly machined, ground, polished and dynamically balanced.
• The propeller is designed to provide circulation of a large volume of air over a greater distance at a minimum sound level.

Wall Mounting Fan

• The fan is mounted on the wall by means of a bracket.
• The angle of inclination/tilt can be varied from 22° to 45°.
• The motor can be swivelled about its vertical axis.
• In case of oscillating models the minimum angle of oscillation is 85°.

Optional Features

• Acid Alkali Resistant Treatment. Fans are specially coated for applications where the fan is exposed to corrosive atmosphere.
• Stepless Speed Regulator These may be provided on single phase models for speed regulation.
• Flame Proof Construction Non oscillating fans are fitted with flame proof motors and are suitable for operation in hazardous location of gas group IIA IIB as per I.S. 2148:1981. 36"(900mm) Sweep Air Circulators can be supplied against special order.

Man coolers (tubular, wall mounting, pedestal) consist of specially designed aerofoil impeller cast in Aluminum alloy, coupled directly on motor shaft the motor with the impeller assembly is mounted on a cradle.

Tubular Provision is made for adjusting the angle of air stream these fans are portable in nature and can be made to stand even on rough surfaces. A long Casing for the impeller system provides an effective means of canalizing air stream in any desired direction.

Wall Mounting These fans can be mounted on the wall or on colum to save floor space. Provision is made for varying the direction of air stream, both vertically and horizontally by providing a tilting head arrangement.

Pedestal Type The entire assembly is mounted on a steel colum and fitted on the heavy base. These are portable in nature.



MAN COOLERS CAN ALSO BE SUPPLIED WITH FLAME PROOF MOTORS AS PER I.S.2148: 1981

We design and manufacture a wide range of centrifugal blowers that are designed to perfection to offer maximum benefits to the clients. The impellers are balanced statically and dynamically that helps in a long working life of bearing and also in a vibration less performance. Conforming to the IS 4894 standards, these blowers are high performing and are available in a capacity starting from 150 M3/hr to 1.50,000 M3/hr. The pressure range varies between 10 to 1500 mm Wg. We also have fans available with double inlet double width.

Our range of axial flow fans are compact in size and are easy to install. Reliable in operation, these fans are made for optimum realisation between air quality, pressure, power consumption. The other features include:

• High efficiency
  
• Aerofoil design
  
• Robust construction to reduce vibration
  
• Low noise level
  
• Special coating & lining for casing & impeller (GRP, FRP, PP, rubber, epoxy)
