Sizes

Sizes vary in accordance with the preferred increments covered in ISO 497-1973(E) R20. These sizes are:
315, 400, 500, 560, 630, 710, 800, 900, 1000mm Diameters.

Applications

This range of fans is ideally suited for moving large volumes of air against low and medium pressures in the following typical applications:

General Ventilation: kitchen canopies, supermarkets, airport buildings, underground car parks, stairwell pressurization, gymnasiums, stadium cloak rooms, industrial buildings etc.
Air-conditioning
Smoke control and exhausting heat from buildings
Condenser cooling
Cooling towers
Combinations of motor speeds, impellers blade pitch settings and the number of blades per impeller (Full and half solidity), provide flexibility in terms of selection. Fans offering good efficiencies can be selected over a range of volumes from 0.1m³/sec to over 27m³/sec at pressures up to 950 Pa

Impellers

Impellers incorporate die-cast aluminium alloy blades of aerofoil section, which are clamped in split aluminium hub. Blades are also available in a glass re-inforced nylon.
Blade pitch adjustment is achieved by slackening the hub clamp bolts and setting the blades to the required pitch prior to re-tensioning the clamp bolts

Balancing

Impellers are dynamically balanced to ISO 1940 grade G6,3.

Casings

Standard casing lengths (SL) usually cover the impeller and motor assemblies. External terminal boxes are provided on the casings of fans fitted with standard totally enclosed motors.
Casings incorporate viewing ports unless access panels are provided.

Direction of Air Flow

Standard form of airflow for direct driven
arrangement would be form B, BU and BD, having
motors mounted downstream of the impellers
