Fläkt Woods Group SA GT-1 CENTRIFUGAL FANS

The GT-1 CENTRIMASTER direct-driven, single inlet centrifugal fans cover air flow rates up to 7 m3/s and pressure rises up to 2000 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 fans 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 fans are deep-drawn in one piece and are fitted to end walls of a common GTLF fan casing. This provides the GTLB 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.
