OPTIONAL EXTRAS - ENERGY SAVING 

Electronically 

Commutated (EC) Fan 

Motor 

Sizes 6 - 60 

Backward curved impellers, direct drive centrifugal fan assemblies with integral 

rotor mounted motor which is statically and dynamically balanced for 

quiet operation. 

Designed for high corrosion resistance, the impellers are laser welded 

aluminium with a galvanised rotor and die cast aluminium EC power module. 

EC motors incorporate integrated electronics to convert AC power to DC for 

efficient and accurate speed control and are adjustable via the microprocessor 

display keypad. 

The fans offer maximum airflow performance while keeping sound levels to 

a minimum. 

The fans are mounted within a floorstand complete with adjustable feet, optional 

legs and floor tile lip. Height of the floorstand; please specify at order. 

EC motors are DC motors with integrated AC to DC conversion; this gives the 

flexibility of connecting to AC mains with the efficiency and simple speed control 

of a DC motor. The EC fan offers significant power reduction in comparison with 

equivalent AC fan at both full and modulated fan speeds. The inbuilt EC fan 

control module allows for fan speed modulation from 15-100%, a standard AC 

fans modulating range is typically 40-100% of full fan speed. 

The EC fan presents superior energy efficiency at full and reduced fan speed 

compared to the equivalent AC fan motor. 

Standard voltage regulated (VR) fan speed controllers offer a linear response. 

By comparison the EC fan is adjusted on demand via the unit microprocessor 

with precision, offering substantial energy savings. The following illustration 

shows a comparison of the typical power input required by each method.

Energy Manager Analysis of system energy consumption can be monitored via a dedicated LCD 

display. Unit parameters can be adjusted via the unit microprocessor control to 

affect energy usage in line with the system need. 

CAUTION 

If Phase Rotation Protection and an Energy Manager unit are both 

required, the Energy Manager will require the addition of a Field Card, 

please contact Airedale.

UNIT LIFTING 

General 

IMPORTANT 

• Employ lifting specialists 

• Local codes and regulations relating to the lifting of this type of equipment should 

be observed 

• Each chain/sling must be capable of lifting the whole unit 

• Lift the unit slowly and evenly 

Only use lifting points provided. 

Do not use 1 chain between 2 lifting points to avoid load shift. 

Ensure that chains/slings DO NOT crush the casework, coil or fan assemblies. 

If the unit is dropped it should immediately be checked for damage and reported 

to Airedale. 

Airedale will accept no responsibility for mishandling during the positioning of 

the equipment. 

CAUTION Check the unit is as ordered, discrepancies or transit damage should be reported 

to Airedale immediately. 

Horizontal Air Discharge The unit is delivered in horizontal air discharge configuration secured to a pallet. Where 

possible the unit should be moved with the pallet in place. 

Use 4 lifting eyes attached to 4 individual slings/chains 

(supplied by others) and attach 2 to each top leg using 

the holes provided as illustrated. 

Vertical Air Discharge The unit is delivered in horizontal air discharge configuration (with the mains isolator and 

fan speed controller already configured for vertical air discharge) secured to a pallet. 

Where possible the unit should be moved with the pallet in place. 

CAUTION 

Before lifting into final position, the unit legs should be re-orientated, refer to instructions 

provided at delivery. 

Care should be taken to ensure the unit does not sustain damage before it is lifted 

into final position. 

> 60° 

Use 4 lifting eyes attached to 4 individual slings/chains 

(supplied by others) and attach 1 to the top of each of the 

4 corner legs using the holes provided as illustrated.
