Testing
Units comply with AS4429 and AS1668 pt1 for Smoke Spill applications. Rated fan performance has been determined by testing to ISO 5801: 2007. Fan sound data has been determined by testing to BS848 Part 2: 1985 or AMCA 300.
Impellers
Aerofoil adjustable pitch impellers are available in various materials, including pressure die-cast aluminium, injection moulded glass reinforced polypropylene (GRP) and nylon. Impellers are balanced to ISO1940 Grade G6.3.
Motors
Motors are of TEFC design. The motor enclosure features IP54 protection. Motor windings incorporate class ‘F’ insulation as standard, although class ‘H’ is readily available. Motor bearings are sealed for life and maintenance-free. Integral thermal overload protection is generally not provided and is the responsibility of the installing electrical contractor.
Failure to provide thermal overload protection voids the warranty.
