Guide to screw models 
MiniORION-E series
MiniORION-E is the oil-lubricated coaxial compressor with direct starter, the smallest of the entire NUAIR screw range. The small dimensions of the air-end/motor unit system allow the machine to maintain an extremely small footprint. Furthermore, thanks also to its extreme quietness, only 65 dB(A), it can be placed near any operating environment.
MiniORION-E is available as a floor-mounted version, or on a 90-litre tank, painted or galvanised.
ORION-E series
The ORION-E range is the compact solution to the continuous compressed air requirements of small businesses.
As a result of the gearless coaxial drive system, all the power of the electric motor is transferred to the air-end without losing efficiency and ensuring top operating reliability.
ORION-E compressors are designed to run continuously under the most severe conditions of use, with special attention to energy consumption, quiet operation, reduced operating and maintenance costs, and ease of installation and use.
MERCURY-E series
This range consists of belt transmission compressors, available in various configurations (floor-mounted, tank-mounted or tank-mounted with dryer), all characterised by extreme compactness and silence.
- Poly-V belt: ensures less power loss and a longer service life than standard belts.
- Electromechanical ON/OFF control on MERCURY-E SE models from 2.2 to 4 kW.
- Electronic control on MERCURY-E models from 4 to 5.5 kW, with LOGIN Mini control unit managing all compressor functions.
- Oil filter and oil separator filter (both spin-on type) and air filter, all quite large, which ensure long service intervals.
- The radial ventilation system ensures optimal operating temperature.
- Phase sequence relay for controlling the direction of rotation of the screw unit.
SIRIO-E series
Compact, reliable and silent compressors, available with or without tank, with or without dryer, equipped with LOGIN Mini electronic controller that manages all machine functions.
- Poly-V belt: ensures less power loss and a longer service life than standard belts.
- The cooling system, with radial ventilation, ensures optimum operating temperature.
- Oil filter and separator filter, both spin-on type to ensure high efficiency and easy maintenance.
SIRIO-E series
Rotary screw compressors with belt transmission, extremely quiet. erter and/or integrated dryer and filters. All models are characterised by:
- “IE3 Premium Efficiency” motors (IE4 for the 75 kW unit);
- latest generation LOGIN electronic controller;
- high-performance screw units of our own design and manufacture;

- suitable for intense and non-stop operation;
- low installation and maintenance costs;
- low noise levels;
- compact design for reduced overall dimensions;
- easy and quick maintenance;
- easy to transport;
- ready for use.
POLAR-E series
POLAR-E is the new series of rotary screw compressors from 5.5 to 75 kW, with 1:1 direct transmission, the benchmark for efficient and safe compressed air production in the industry.
In the 5.5 to 15 kW power range, the lineup includes ON/OFF models in various configurations (floor-standing, with tank, and with tank and dryer) as well as POLAR-E PM inverter versions with similar configurations.
All models in the POLAR-E PM series are equipped with the LOGIN electronic controller, which constantly monitors the compressor, ensuring perfect functionality and reliability of the unit under all operating conditions.
