Axial Flow Fans

 »  AIR HANDLING ENGINEERING is an art, please consult us for your specific air handling needs.

Axial Flow Fans:

 » Axial Flow Fans are available in
Capacity: Up to 3,00,000 M3/hr
Pressure: Up to 100 mm of WG.
 » To achieve high efficiency, fans have a defined hub ratio of 75 to 25 for given capacity, pressure and speed
 » Impeller blades are adjustable type and can rest at designed angle to suit the system resistance
 » Fan can run in parallel to suit capacity and in series for higher pressure
 » Impeller is made of aerofoil profile from cast aluminum alloys
 » Bifurcated type fans are available for handling corrosive gases
 » High efficiency can be achieved due to wide selection of sizes, hub ratio, number of blades and pitch angle

Roof Exhaust Fan:

 » Badly ventilated room / work shop can reduced worker efficiency by as much as 30%. Lack of fresh air means tiredness and lack of constriction resulting in more wastage and more accidents. AEROMATIC roof mounted ventilation units counteract exactly these dangers. By improving the air in the work room you improve both the efficiency and output of your workers.
 » Applications: All major industries where fumes and heat are produced such as foundries, annealing plants, welding plants, steel drawing works, rolling mills, glass plant, power plant, etc.

Bifurcated Axial Flow Fan:

 » Bifurcated Fans specially designed for handling hot, corrosive gases. The drive direct / vee belt is totally isolated form gas stream
 » Applications: Chemical, fertilizer, paper plants, etc.

 » SILENCER: For applications requiring quiet operation, customs built attenuation packages can be provided on the fan inlet or outlet. attenuators are aerodynamically and are designed to significantly reduce noise while adding only minor resistance to air flow.

Variable Inlet Vane: For frequent continuous volume control, a variable inlet vane can be provided. Variable inlet vanes are available for each specific fan size and are bolted to the fan's flanged inlet. The vane action during dampering works to spin the air in the direction of the wheel rotation this resulting in lower power consumption. Vane mechanism is outside of the air stream and is controlled buy a single vane lever.
Variable inlet vanes can be set up for manual or automatic operation. The variable inlet vane's inlet is flanged and drilled to accept ductwork or and inlet bell as the system requires.

Bird Guard: Safety screening can be provided for installation in the fan inlet, fan outlet, cone or belt.

Spark-Resistant Construction: Belt Drive / Direct Drive with Spark-Resistant Construction are available.

Inlet Bell: For systems with not ductwork on the fan inlet, it is advantageous to install an inlet bell is a torosoidal shape to avoid inlet losses. The inlet bell is a torosoidal shape to provide a smooth entrance to the fan. Inlet bell are flanged and drilled to mate up with the fan's flanged inlet.

Inlet/Outlet Cone: Transition pieces, called cones, can be provided for both the inlet and outlet. Cones are provided to adapt from the fan diameter to the adjacent ductwork diameter. Cones are flanged on both ends and drilled to mate up with fan's flanged. Cones are available with an access door if required.
Outlet cones can be utilized to affect performance and transform velocity pressure into static pressure.

Companion Flanges: For ease of installation of adjacent ductwork, companion flanges can be provided. Flanges are rolled angle rings, drilled to match the fans inlet or outlet flanges.
