The ICQ series is a range of inline duct mounted fans for use in general ventilation systems. All models are built around high performance centrifugal impellers driven by totally enclosed fan cooled (TEFC) or external rotor motors (ERM). Note that single has ICQ series fans are only available in ERM models.
Cases are fabricated from galvanised sheet steel with standard duct flanges for easy installation. Impellers are high efficiency backward curve centrifugal type. The impeller and motor assembly is supported by a robust galvanised steel frame for long, trouble free service.
Motors are of TEFC or ERM design. Motor enclosure feature IP54 protection as standard with higher ratings are available on request. Motor windings incorporate class ‘F’ insulation as standard although class ‘H’ is readily available. Motor bearings are sealed for life and maintenance. 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.
Rated fan performance has been determined by testing to ISO 5801 : 2007. Fan sound data has been determined by testing to ISO 13347 : 2004.
