1 Range of in-line duct centrifugal fans, manufactured from high grade corrosion resistant pressed galvanised steel and supplied as standard with a prewired wiring junction box and a robust mounting foot. All model include an enclosed type, single-phase external rotor motor with factory matched backward curved nonstalling impeller. (1) Models 355 and 4 are manufactured in sheet steel protected against corrosion by cataforesis primer and black polyester paint finish. VENT- to VENT-315 Motors 315 models: Motors are IP44, class B insulation with ball bearings and safety thermal overload protection. 355 and 4 models: Motors are IP54, class F, with ball bearings and safety thermal overload protection. Electrical supply: Single phase 23V-5/6Hz. Three phase 23/4V-5Hz (models 355 and 4). (See characteristics chart). All models are speed controllable. Additional Information L version: High performance models. B Version: Standard performance models for lower noise level requirements. Impellers from to 16 models are manufactured from injection moulded plastic. VENT-355 and VENT-4 Mounting foot Supplied with unit as standard (-315 models). 815
