Technical details

MAV fans are high efficiency duct ventilators, designed to increase airflow performances and
lower noise emission.
The fans have diameters ranging from 300 mm to 1250 mm.
The fans normal working temperatures range from -40° C to +120° C, and can reach up to
200/300° C with customized solutions.

MAV fans can be assembled employing a variety of HW Ventilation impellers.
Fixed pitch axial flow impellers – 6/8/10/14 blade configurations
• TS (subtypes G, D) – airfoil profile axial impellers, diameters from 230 mm to 906 mm
• Q – sickle profile axial impellers, diameters from 230 mm to 750 mm
Variable pitch axial flow impellers – 5/9/12/16 blade configurations
• TM (subtypes N, V) – airfoil profile axial impellers, diameters from 300 mm to 1270 mm
• R – reversible axial impellers, diameters from 550 mm to 966 mm
• SR – sickle profile axial impellers, diameters from 550 mm to 1100 mm
• C – sickle profile axial impellers, diameters from 450 mm to 1282 mm
All HW Ventilation impellers have been tested against ErP 2015 directive for energy efficiency of axial
fans in our AMCA 210-07 wind tunnel.

Hubs and bosses are made of a highly resistant light aluminum alloy.
Customized solutions for every special need in terms of performance, design, color are available
upon request.

MAV fans are available also in high-temperature resistant versions, which employ C impellers
totally made of aluminum. Such special configurations have been successfully tested by Applus
third-party, according to international standard EN 12101-3:2002. The fan successfully resisted
at a temperature of 200°C for two hours, and at 300°C for two hours.
The full test report is available upon request.

Casing:
Short or long casing made of steel sheet, with fixing flanges.
The casing can be treated with epoxy paint to prevent corrosion and rust.
AISI Inox 304-316 available upon request.
Depending on the casing length, the motor can be totally (long-casing) or partially (short-casing)
inside the casing (see Dimensions).
