1 N /1/08 19:26 Página 50 BLT DRIVN BINT NS Series rated cabinet fans NW pproved to N standard Range of belt drive cabinet fans designed for smoke extraction in fire conditions and certified ( marked). The casings are manufactured from heavy gauge galvanised sheet steel. ll models incorporate double inlet forward curved centrifugal impellers. Belt-drive transmission system mounted external to the air stream. Motor mounted within the fan cabinet onto a specific support giving optimal belt tension. Supplied as standard in horizontal discharge (code H) or vertical (code V) configuration with motor, pulley and belt assembly on the right hand side of the unit when viewed from the discharge end. Horizontal discharge version -H Vertical discharge version -V Motors ll motors are IP55, class insulation. lectrical supply. Three phase 20/ 00V-50Hz, up to kw. 00V-50Hz, for higher motor powers. (See characteristics chart) On request Motor, pulley and belt assembly fitted on the left hand side of the unit when viewed from the discharge end (TI version). Two speed motors (/8 and /6 poles). P P L I T I O N S rkings ommercial and industrial kitchens ompact design asy to install utomatically tensioned and maintenance free system Robustness Motor inside the fan casing, providing a smaller size and a higher compacity The cabinets have fixing points on the corners easing the installation either on the floor or ceiling xclusive of S&P. The only system ensuring a constant belt tension without any maintenance required Quality finishing, with aluminium corners providing a high robustness 50
