Technical details

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

MAV ventilators can be assembled employing a variety of HW Ventilation fans.
Fixed pitch axial flow fans – 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 fans – 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 ventilators 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 ventilator 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.

Motor:
High efficiency (IE2, IE3) standard asynchronous three-phase motors.
• Standard tension 400V, 50Hz
• Power from 0.12kW to 15kW
• 2, 4, 6 poles
• Suitable for use with inverter
• Class F insulation
• Housing protection level IP55
• Low noise
• Simple maintenance
• Available configurations: B3 with foot mounting, flange mounted B5, flange mounted B14

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).
