AS – SERIES
AXIAL RING FAN
- V = 100 ÷ 140000 [m3/h]
- Ps = 10 ÷ 1000 [Pa]
AS series fans are suitable for non-ducted applications requiring low and medium pressures, high flow rates of clean or slightly dusty air in the temperature range from -20°C +50°C, in special execution they can exceed these limits.

The fields of industrial application are many among which food, naval, heat exchange, refrigeration, drying, Oil&Gas, petrochemical, milling.
The construction shape of the conveyor can be optimized to improve aeraulic efficiency and noise through the round suction edge. The conveyors are made of carbon steel with adequate thickness and welded motor support, epoxy painting ral 7032 with environmental corrosivity class C3m according to ISO 12944.
impellers, The impellers, made with a die-cast hub in aluminium alloy and wing profile blades in glass-reinforced polypropylene (PPG) or glass-reinforced nylon (PAG), are balanced with grade G. 6.3 according to ISO 1940 and have a fixed or variable restriction (from D. 700[mm]); the electric motors, in direct coupling, are asynchronous three-phase or single-phase 2/4/6/8 poles in B3 construction and in continuous duty S1 according to UNEL-MEC and IEC standards.
