Fan type “ΗΑ” supply air at 200 m3/h up to 20.000 m3/h and have static pressure that reaches 16.000 Pa. The impeller has curved blades with backward inclination and is appropriate for the passage of air that is relatively clean.
Fan type “HAL” supply air at 1.000 m3/h up to 200.000 m3/h and have static pressure that reaches 10.000 Pa. The impeller has flat blades with backward inclination and are appropriate for the passage of air with large percentage of dust. Fans – blowpipes of type “Ο”, supply air from 80 m3/h up to 3.000 m3/h and have static pressure that reaches 16.000 Pa for single stage and 50.000 Pa for multistage. The impeller is appropriate for clean air.
The operating temperature-if required- can be up to 800°C.
The construction material can be manufacturing steel, stainless steel anti friction steel.
