Centrifugal Fans (GTL-1)
The GTL-1 direct driven, single-inlet centrifugal fans cover air flows up to 7 m3/s and pressure rises up to 2000 Pa. The fans are available with different types of impellers:
- Impellers with forward-curved blades (GTLF fans)
- Impellers with backward-curved blades (GTLB fans)
Besides the normal version, the fans are also available in a sparkproof version. The smoke extraction version of GT has been tested by the French CTICM institute and by the Russian VNIIPO institute. CTICM has tested the fans for +400 °C, 2 hours and the tests cover GTLB-1-025–071 and GTLF-1- 031–050. VNIIPO has tested the fans for +400 °C, 2 hours and for +600 °C, 1 hour and the tests cover all single-inlet GT-fans. The fans in the spark-proof version conform to the German standard VDMA 24 169 3.1 – 3.2 and 3.4. The inlet cone is made of brass. In the GTLF fans, the inlet is fitted with a brass band. If the inlet of the fan is connected to the ducting, the single-inlet fans are rated for continuous operation at temperatures up to +80 °C. If the motor is exposed to the air stream (i.e. on a free-inlet fan), the ambient temperature must not exceed +40 °C. Motors for higher temperatures are available on request.
The casing is made of Sendzimir galvanized sheet steel. The side plates are stamped in one piece and the inlets are deep-pressed in the end walls. The casing is jointed by the "Pittsburg folding method" which produces tight, strong joints. The "Pittsburg folding method" and the deep-pressed inlets ensure a stable design and high, consistent quality. The fan tongue offers optimized aerodynamic properties.
