1 asy to install Supports to facilitate installation in the roof. XTRACTION (type B) SUPPLY (type A) High quality steel sleeve nsuring the long life of the fan. Range of axial roof fans with horizontal air discharge configuration available in version: B models for air extract. A models for air supply. Base manufactured from galvanized sheet steel. Cowl manufactured from spun aluminium. The impellers for models 31 to are manufactured from one piece injection moulded plastic, reinforced with chemical anchored fibreglass for additional strength. Models to 1 incorporate separate plastic blades locked within a die cast aluminium hub. Available, depending upon the model, with single or three phase motors in,, 8 or /8 poles. Motors All motors are IP (1) Class F () with thermal protection (3) and ball bearings greased for life. lectrical supply: Single phase 3V-Hz (Capacitor located inside the wiring terminal box). Three phase V-Hz. (See characteristics chart). All single phase models are speed controllable by voltage except HCTB/-, HCTB/-3. All three phase models are speed controllable by autotransformer, except models HCTT/-, HCTT/-3, Ø 71 to 1. Three phase models, 1 speed motor, are speed controllable by inverter. (1) 8 to 1 models are IP. () Air stream temperature limits -ºC to +7ºC (except models 8 to 1 suitable for usage in environments from -3ºC to +ºC. (3) 8 to 1 models are not equipped with thermal protection. ATX versions HCTT On request, explosion proof versions in accordance with ATX Directive, for 3 phase models. For ambient working temperatures from -ºC to +ºC. - ATX Flameproof - Gas Only available for 8 to 1 models II G xd IIC T II G xd IIB T - ATX Increased safety - Gas II G xe II T3 - ATX - Dust II 3D DIP 1ºC or 13ºC Impeller dynamically balanced Impellers are dynamically balanced, according to ISO 19 standard, giving vibration free operation.
