FAN PERFORMANCE:
All fans are tested to the latest internationally recognised standard ISO5801 Part 1, installation category D for aerodynamic performance and BS848 Part 2 (1985) for acoustic performance.

Coupled with the above fan diameters, the adjustable pitch Aerofoil impeller gives the exact performance required, with a non-overloading fan characteristic.

IMPELLERS:
A unique high efficiency aerofoil section blade with a purposely-smoothed hub and clamplate for adjustable pitch angle availability. The Woods impellers are all high pressure die cast to offer thin aerofoil sections for low generation of noise levels. Every cast aluminium component is X-rayed using Real Time Radiography inspection prior to assembly.

MOTORS:
All motors are totally enclosed air stream rated Class F insulation. Constructed from aluminium as standard with special 'T' slot and pad mounted fixings. Suitable for horizontal through to vertical shaft operation. Supplied IP55, with removable drain plugs. Sealed for life bearings lubricated with wide temperature range grease. Flameproof motors are certified to BS5501 Parts 1 and 5 suitable for use in gas groups 2A and 2B. Temperature class T4.
ELECTRICAL SUPPLY:
220-240 V / 50 Hz / 1 ph
380-420 V / 50 Hz / 3 ph
TEMPERATURE RANGE:
-40°C to 50°C as standard. Fans can be operated up to 70°C with appropriate deration of motors (please enquire).
CASINGS:
JM Aerofoil fans are available in either a long cased form complete with externally mounted pre-wired electrical terminal box or short cased for duct or plate installation. Casings are spun from sheet steel with integral pre-drilled and radiused inlet flanges. The galvanised finish gives a high resistance to corrosion and makes it ideal for external use.
ANCILLARY EQUIPMENT:
Silencers, Mounting feet, Vibration isolators, Matching flanges, Flexible connectors, Air operated non-return dampers, Guards, Bellmouth inlets.
