IRT 4 400B Inline Rectangular Duct Fan

The S&P IRT/4-400B is a three-phase inline rectangular duct fan built for general ventilation where a fan must sit within a rectangular ducted system or where installation space is tight. It uses a high performance, dynamically balanced backward curved centrifugal impeller in a heavy gauge galvanised steel casing, delivering up to 9580 m³/h of free air. The external rotor motor carries Class F insulation with thermal protection and runs on a 230/400V-50Hz three-phase supply. Speed is controllable by transformer or frequency drive, and the hinged inspection door plus remote IP55 terminal box make cleaning, maintenance and control wiring straightforward. The fan can be mounted in any orientation.
