Serias U/SB

The U/CB series centrifugal fans are designed to take up clean or slightly dusty air at  temperatures of up to a maximum 80°C.
These fans are used for ventilation and air conditioning plants and generally in industrial applications requiring high flow rates.
The strong steel sheet spiral casings are rimmed and welded. These fans have a base for the motor and the discharge angle can be regulated in 45° steps by rotating either clockwise RD or counter-clockwise LG (see discharge direction table).
The welded steel sheet impellers with backward-curved blades have been carefully balanced, both statically and dynamically.
The motors installed are asynchronous, three-phase, B3, with IP55 protection, self-ventilated, designed for continuous service and are UNEL and IEC compliant.

Series U/PB

The U/PB series centrifugal fans are designed to take up and convey air, even if dusty, at temperatures of up to a maximum 80°C.
These fans are used in industrial plants requiring medium-to-high pressures; furthermore they can also be used to convey solid materials, except strings, mixed with air.
The strong steel sheet spiral casings are rimmed and welded. These fans also have a base for the motor and the discharge angle can be regulated in 45° steps by rotating either clockwise RD or counter-clockwise LG (see discharge direction table).
The strong welded steel sheet impellers with high performance, backward-curved blades, have been carefully balanced both statically and dynamically.
The motors installed are asynchronous, three-phase or single-phase, 2 or 4 poles, B3, with IP55 protection, self-ventilated, designed for continuous service and are UNEL and IEC compliant.

Series U/PBM

The U/PBM series centrifugal fans are designed to take up air, even if dusty, at  temperatures of up to a maximum 80°C.
They are generally used in the industrial plants requiring medium-to-high pressure; they can also be used to convey solid materials, except strings, mixed with air.
The strong steel sheet spiral casings are rimmed and welded. These fans also have a motor support base and the discharge angle can be regulated in 45° steps by rotating either clockwise RD or counter-clockwise LG (see discharge direction table).
The steel sheet impellers with high performance, backward-curved blades, have been balanced both statically and dynamically.
The motors installed are asynchronous, three-phase or single-phase, 2 or 4 poles, B3, with IP55 protection, self-ventilated, designed for continuous service and are UNEL and IEC compliant.

Series U/MPR

The U/MPR series centrifugal fans are designed to convey air, even if dusty, at  temperatures of up to a maximum 80°C.
They are used in all the industrial applications requiring medium-to-high pressures and low noise.
The strong steel sheet spiral casings are rimmed and welded. These fans also have a base for the motor and the discharge angle can be regulated in 45° steps by rotating either clockwise RD or counter-clockwise LG (see discharge direction table).
The spot-welded impellers with high performance, backward curved blades, have been carefully balanced both statically and dynamically.
The motors installed are asynchronous, three-phase or single-phase, 2 poles, B3, with IP55 protection, self-ventilated, designed for continuous service and are UNEL and IEC compliant.

Serias U/APE

The U/APE series centrifugal fans are designed to take up air, even if dusty, at  temperatures of up to a maximum 80°C.
These fans are used in all the industrial systems requiring high pressures and low flow rates. Furthermore they can also be used for pneumatic conveyance.
The strong steel sheet spiral casings are rimmed and welded. These fans also have a base for the motor and the discharge angle can be regulated in 45° steps by rotating either clockwise RD or counter-clockwise LG (see discharge direction table).
The welded steel sheet impellers with forward-curved blades have been carefully balanced both statically and dynamically, and are connected directly to the motor shaft.
The motors installed are asynchronous, three-phase or single-phase, 2 poles, B3, with IP55 protection, self-ventilated, designed for continuous service and are UNEL and IEC compliant.
