EV is a single suction centrifugal fan in painted steel metal with galvanized blades, suitable for the extraction of air with low concentration of dust. The particular low air flow and low pressure allow a wide range of use of EV fans for the extraction of welding smokes (together with extraction arms) to guarantee optimal performance (low energy consumption) with low noise impact.
EV models without anti-vibration damper are for flexible hoses. In case of rigid tubes an anti-vibration damper is required.
The fan is made of welded steel with adequate thickness and it is painted black. The standard fan is in B5 without motor support frame. The impeller has curved forward-lined blades, statically and dynamically balanced according to ISO Standards, keeping noise and vibrations at minimum levels.
Motor
Asynchronous motor, three-phase or single-phase, IP55, according to UNELMEC Standard.
