GIANNESCHI
EL/Axial Blowers

SR/ST Series

EL-ST: Impeller made with an conical collet with cast iron nozzle, steel Fe360B formed cap, airfoil blade profile made in spark-proof aluminium alloy. Manual adjustable blade orientation in still position accurately balanced.

EL-SR: Impeller is made of die-cast aluminium, airfoil blade profile, manual adjustable blade angle in still position and dynamically balanced.

In both models the housing is made of Fe360 steel sheet with a large suction nozzle. The connection flange is made according to DIN 24154. Down stream guide vanes give a performance improvement, particularly in pressure, efficiency and noise. The presence of down stream guide forces the system to be used only in “blades-motor” flow direction, for this reason both models are not reversible.
