AF SERIES – Axial Flow Fans

Pre Engineered Standard Fans

The Aerotech range of Axial Flow Fans is designed to meet the needs of a wide variety of industrial applications, combining strengths and long life with competitive cost.

Impellers – These high efficiency, non-corrosive impellers are injection moulded, pressure die cast or gravity cast from a range of materials including aluminium, glass reinforced polypropylene (GRP) or glass reinforced nylon (GRN). Impellers have a safe operating temperatures of 160°C for aluminium, 100°C for GRN and 65°C for GRP. The hub comes with a unique taper lock bush to ensure positive shaft locking.
Adjustable Pitch – Impellers have adjustable blade angles from 4° through to 40°. It is pre-set in the factory, to perform precisely to the customers requirements and allows the user to alter the blade pitch angle to match any change in conditions after installation, within the load limits of the motor.
Standard casings are of mild steel construction with hot dip galvanised finish. An external terminal box is provided for easy connection to wiring circuit. The casing has a drilled end flange at both ends.
Corrosive Atmosphere – Impellers and casings can also be fabricated in stainless steel or mild steel with special paint finish.
Motors – The motor is mounted on a platform inside the casing permitting temperature rise of 65°C. Single phase,and flameproof motors are available on request.
Balance – All fans are electronically balanced and are completely free of vibration. This factor is essential for smooth economical running and assists in the reduction of noise.
Sound Level – Low noise level is achieved by the superior aerofoil profile of the blades.
Contra-Rotating and Multi-Stage Fans – Contra-rotating fans can be supplied as two tube axial fans bolted together.
External Motor Drive (Belt Drive) Fans – The impeller is belt-driven by a motor externally mounted on the side of the casing. This allows the motor to be completely isolated from the air stream and is suited for hazardous conditions.
External Motor Drive (Belt Drive) Fans – The impeller is belt-driven by a motor externally mounted on the side of the casing. This allows the motor to be completely isolated from the air stream and is suited for hazardous conditions.

These procedures underpin Aerotech Fan’s commitment to the supply of quality goods, services and customer satisfaction.
