Guide to screw models
Screw compressors are used in a wide range of industries, from manufacturing to automation, and are ideal for applications requiring a constant and reliable air flow.
NUAIR ranges are distinguished by their high energy efficiency, their ability to operate continuously and quietly, their minimal maintenance requirements and their inimitable design.
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.
