The aerodynamic blades and motor housing shall be manufactured from prime quality galvanised sheet steel.
Motors
Motor insulation Class B, suitable for operating temperatures from -15ºC to +40°C and atmospheres up to 95% RH.
All sizes are ideally suitable for speed control by electronic or voltage reduction. Roof Units would recommend that a voltage reduction Auto Transformer speed controller is used with all Quiet Pack units to ensure minimum noise levels during speed control and to eliminate any possibility of harmonic noise levels which occur when using electronic speed controllers at lower speeds.
Performance
The fan performance, shall be in accordance with tests to BS848 Part 1 1980, with the fan sound levels, measured in a reverberant chamber in accordance with BS848 Part 2 1985.
