Smokes and hot gas exhausters - Industrial ventilation - Tertiary ventilation Bifurcated fan with axial impeller, directly driven with motor outside the airflow in a sealed chamber to resist corrosion, high temperatures or severe conditions. Diameter of wheel / impeller : 400 to 1400mm Flow : 0 to 100000m3/h Pressure : de 0 à 110mmWG Temperature : 400°C maximum AXIAL FAN Type H-Special
Smokes and hot gas exhausters - Industrial ventilation - Tertiary ventilation Special axial fan according customer's requirements: casing and impeller out of galvanized steel, stainless steel, aluminium, 1 or 2 stages, with ancillaries, or specific functions such as roof application… Diameter of wheel / impeller : 300 to 2000mm Flow : 0 to 250000m3/h Pressure : de 0 à 160mmWG Temperature : 600°C maximum DOUBLE STAGE
Industrial ventilation - Tertiary ventilation Double stage / same rotation direction
Joint of 2 fans with the same rotation direction, each fan giving a pressure, the addition of these pressures is around 1.5 times higher than of one fan alone.
Double stage / contra-rotation
When the second impeller of a set of 2 fans has a reverse rotation direction than the first, the set is said to have contra-rotation and the total pressure given by the set is then around 2.3 times higher than of one fan alone. Diameter of wheel / impeller : 1000 to 1400mm Flow : 0 to 100000m3/h Pressure : de 0 à 200mmWG Temperature : 40°C maximum.
