Fläkt Woods Group SA GT-3 CENTRIFUGAL FANS

The GT-3 CENTRIMASTER belt-driven, single inlet centrifugal fans cover air flow rates up to 27 m3/s and pressure rises up to 3300 Pa. The fan series consists of centrifugal fans available with two types of impeller: - Forward-curved blades for the GTLF fans - Backward-curved blades for the GTLB and GTHB fans The backward-curved blades in the GTLB fans have the same aerodynamic characteristics as those in the GTHB fans, but the GTHB is a reinforced version for higher speeds. The design of the fan inlet is of vital importance to achieve high fan efficiency and a low level of noise generated by the fan. On the size 025-071 GTLF fans, the inlet is directly deep-pressed into the end walls. The inlet cones of the GTLB and GTHB fans are deep-drawn in one piece and are fitted to end walls of a common GTLF fan casing. This provides the GTLB and GTHB fan casings with additional rigidity. On the size 080-140 fans, the inlet cone is made separately for both types of fan and directly fitted to the end walls.
