Aarkay’s Fans are preferred throughout for their efficiency and  durability. The entire range includes various sizes of Hot Air Fans, I.D. Fans, Axial Flow Fans for the Withering Trough, and Centrifugal Fans. Reaffirming its persistent commitment to R&D and innovation, AARKAY has recently launched a new range of Energy saving Light Aluminium Alloy Axial Flow Fans for the Withering Trough with improved profile designs which reduce power consumption and offer 20% higher CFM capacities as compared to the old-generation Aluminium Blade Fans with the same size and power input.

 

AXIAL FLOW FANS

  HIGHER EFFICIENCY AND SUSTAINED PERFORMANCE WITH LIGHT ALUMINIUM ALLOY BLADES 

Aarkay Axial Flow fans meet the requirements of General ventilation and air conditioning field. In the Tea Industry 'AARKAY' AXIAL FLOW FANS are used in withering troughs for exhaust and in miracle mills.

Aarkay Axial Flow fans are designed and constructed to give efficient trouble free service and both initial and operating cost are reduced to minimum. Cast aluminium alloy 6 bladed impeller directly mounted on Motor Shaft and aerodynamically designed wide blades ensures smooth and streamlined airflow with minimum turbulence for withering tea leaves so that they roll well and take on twist. Rotors are dynamically balanced and run within permissible noise and vibration levels. Casings are made of heavy gauge drums with drilled flange at both ends and complete with legs for horizontal, ceiling or floor mounting. A Fan Guard for safety and Inlet flaring for minimizing eddy losses are regular features of two design.

Dampers, Transition pieces, Hot Air risers, D.O.L. or Star-Delta Starters and Reversible Switches are quoted as optional extras.

Aarkay Axial Flow fans are generally manufactured in 3 popular sizes to suit different leaf bed areas of troughs withering but special size Fans to suit Various Capacities of troughs can be custom built as per buyers' requirement.

CENTRIFUGAL FANS

  HOT AIR, INDUCED DRAFT AND FERMENTING FANS

 

 

 

Aarkay Centrifugal Fans are most suitable for Ventilation, Fume, Exhaust, Forced Draft, Induced Draft Hot Air Circulation, Cement Kiln Exhaust, Combustion Air, and Pneumatic Conveying. In the Tea Industry, Aarkay Centrifugal Fans are best suitable for discharging hot air produced by oil heaters and coal fired stoves into Tea drying chambers and withering troughs, for providing cold air to trough fermentations and as I.D. Fans.

 

Impellers are made of High Strength die-pressed steel blades. The complete impeller assembly is mounted on two heavy duty bearings and housed in a mild steel casing. Aarkay Centrifugal Fan are designed to ensure maximum air delivery at required pressure and minimum power requirement .

 

The Fans may be arranged for V-drive or directly mounted on Motor Shaft Speed is adjustable by changing the Motors and / or pulleys. Complete Electrical drive systems are supplied with Fans, if required.
