Production The entire production procedure is carried

out in-house, at our Italian production plants; design, machining, assembly, testing, packaging and shipment. Every product, built in compliance to the applicable standards, is closely followed up in all process steps by trained and qualified staff, to ensure that specific quality and functional tests are passed.Besides the fully-assembled product, NU AIR offers a wide range of air-ends, intake regulators, thermostatic valves and accessories for the assembly of rotary compressors.

Innovation NU AIR's construction philosophy is based on the selection and simple assembly

of the most reliable and efficient technical solutions.The higher wear resistant Poly-V belt drive, the oversized combined air/oil exchanger with centrifugal cooling fan and thermostatic control to ensure the ideal operating temperature, and high-efficiency electrical motors, make NU AIR compressors robust and reliable work companions, even in the most heavy-duty conditions.

Quality NU AIR rotary screw compressors are the answer to the needs of small and medium-sized enterprises, where compressed air is one of the main sources of energy. A team of highly skilled technicians and operators work meticulously to check product efficiency and quality, relying on the most up-to-date technology and sophisticated equipment. Assembly and testing performed on automated lines, robotic systems of the latest generation and computer tools for design and control are the main investments that the company has implemented to realise products that meet the market’s quality standards. In addition and more importantly, components are manufactured on CNC machines and are 100% tested.

Screw technology NU AIR air-ends feature one of the most advanced rotor profile designs available.

The manufacturing process is fully integrated, thanks to ultra modern machine tools and sophisticated operating instrumentation that provide the highest quality standard.

A solid modeling CAD system allows for ideal component arrangement. The production process of the rotors goes through 4 different machining steps that

make it possible to achieve superior machining accuracy and consistent performance. This level of precision means any male rotor can be indistinctly matched with any female counterpart.

All air-ends are individually tested after their assembly and after their manufacture and then a further time following assembly on the completed compressor.

The unique “ReVerso” profile allows the air-end to be driven by either the male or female rotor shaft. This specific feature effectively means that the air-end is suited to a wider range of applications, both in terms of performance and pull operated by electrical or endothermic motor.The performance characteristics of each single component are logged in our systems, being fully traceable back to the exact time of manufacture and testing.

Product range assetsThe range of NU AIR screw compressors is broken down into five product lines, designed for industrial applications and offered with different power or technical set-up, depending on the customer's specific demands. All models in the range have the following benefits in common, which are typical of NU AIR screw technology:

High volumetric yield The free air delivered from our hi-efficiency air-ends contributes to lower energy

consumption and therefore significant savings.

Reliability The low speed of the air-end guarantees minimal wear and long durability.

Suitable for intense and non-stop operation 24hrs without performance drop.

Low installation cost The versions fitted with a tank and dryer are ready for use, with no added cost of installation.

Low noise levels This means the operator can install the compressor near the workstation.

Compact design means reduced dimensions

Easy maintenance NU AIR rotary screw compressors are built with an emphasis on making routine

maintenance tasks simple and components easily accessible.

Air-ends 100% designed and made in Italy.

Intake valve 100% designed and made in Italy.

Axial fanSupplies the optimum cooling air flow for the generously sized air/oil cooler: safe operation in any environmental condition with minimum noise level.

Minimum pressure valve Built in house with oxide free material, fully machined. A sharp technical choiceto grant maximum reliability in any operational conditions.

The entire manufacturing cycle is carried out in-house, ensuring our air-ends are 100% designed and made in Italy.

Sirio 30-37 kWConstruction features and advantages:

All major components of the compressor, such as the intake regulator, minimum pressure/check valve and separator unit, are designed and manufactured by NU AIR with highly evoluted CNC machines.

The cooling air flow, channeled by the thermostatic controlled fan, cools down an oversized combined oil/air heat exchanger: this lets the compressor run in severe temperature conditions.

The wide front and rear paneling grants ease of access, reducing inspection and maintenance time.

Transmission between air-end and electric motor is performed by Poly-V belts ensuring long life and minimum maintenance.

Air-ends entirely designed and made in Italy, just as the intake regulator and separator block with minimum pressure/check valve.FS130 is mounted on Sirio 38 models.

Dryer moduleSirio 31-37-38 compressors with dryer module provide

clean, dry air that improves the system’s reliability, avoids costly downtime and production delays,

and safeguards the quality of your products.

Minimum pressure valve Built with oxide free material, fully machined. An ideal technical solution to provide maximum reliability in any operational conditions.

Cooling systemThe axial fan ensures the ideal operating temperature, even in extreme working conditions.All air-oil circuit hoses are made of rubber covered with a metal mesh resistant to high temperature.

Air filterThe air filter with cartridge and dual filtering stage allows its use even in dusty environments.

Oil filter and separator filterBoth spin-on type, they ensure maximum efficiency and simple maintenance.

IR60 intake regulatorNormally closed electro-pneumatic system. It adjusts compressor operation, guaranteeing the minimum pressure necessary during idle running and maximum energy saving at start-up, streamlining the energy cost/air generated ratio.


Entirely developed and assembled in NU AIR Italian facilities. The superior components selection and the compact internal layout make this range of compressors stand out in terms of high performances and minimum footprint.

The cooling air flow, channeled by the thermostatic controlled axial fan, cools down an oversized combined oil/air heat exchanger: this let the compressor run in severe temperature conditions.

Cabinet is fitted with a standard prefilter panel filtering the incoming cooling air. Cleaner components for a longer life and easier servicing.

Wide front and rear access panels allow easy maintenance and immediate check of all main components, reducing time of inspection and maintenance.

FS130Air-end entirely designed and made in Italy, just as the intake regulator and separator block with minimum pressure/check valve.

Sirio Variable SpeedMaximumenergy saving

Energy costs and maintenance costs significantly exceed the initial investment in a Company. The NU AIR range at Variable Speed, especially in systems with variable air consumption, ensures the reduction of energy costs.

Sirio 37, 56 and 75 models are also available as Variable Speed (VS), equipped with Inverter option, that enables the compressor to adapt to the flow rate demanded by the application.

They are particularly suitable for those companies that use compressed air with frequently changing flow: the variable frequency drive allows the machine to adjust the flow rate to the actual demand.

The electronic controller monitors and controls air-end speed, modulating the air production in order to keep constant pressure in the network.

Immediate advantages of this feature are the constant network pressure, the optimized electric power consumption, matching the real compressed air demand, and the minimum wear of the mechanical components, which are usually stressed during the idling/load switching of the standard compressors.
