NUAIR Orion Rotary Screw Compressor

Designed for demanding industrial environments where reliability, energy efficiency, and low operating costs are essential, the NUAIR Orion is a three-phase rotary screw compressor range available in 4 kW, 5.5 kW, and 7.5 kW configurations. Built around a gearless coaxial direct drive system, the Eco-Drive 1:1 transmission transfers the full power of the electric motor directly to the high efficiency FS 26TFC air-end, eliminating energy losses associated with belt or gear-driven alternatives and delivering over 35% energy savings compared to conventional designs.

Rated for continuous duty operation and running at between just 63 and 67 dB(A), this direct drive compressor is significantly quieter than comparable machines, making it well-suited to workshops, production facilities, and industrial settings where noise levels and uninterrupted operation are both critical considerations. The compact, tank-mounted design ensures a balanced and manageable footprint across all three models in the range. The unit features a 1/2" outlet connection, compatible with a wide range of air fittings and push-button safety couplings.

For applications requiring dried, clean air, the Orion is also available as a package with an integrated refrigerant dryer.

• Eco-Drive 1:1 direct drive transmission: The gearless coaxial drive system transfers motor power directly to the air-end with no mechanical losses, delivering over 35% energy savings compared to belt or gear-driven alternatives.
• High efficiency FS 26TFC air-end: Purpose-engineered for maximum performance and durability, ensuring consistent compressed air output across the full duty cycle.
• Continuous duty rated: Built to run around the clock under the most demanding industrial conditions, providing a dependable source of compressed air with no scheduled downtime for cooling.
• ETMII electronic controller: The backlit alphanumeric display monitors and displays operating pressure (load and no-load), oil temperature, total operation hours, and load operation hours, giving operators full visibility of machine status at a glance.
• Programmable cooling fan temperature: Allows operators to set fan activation thresholds to suit the installation environment, reducing unnecessary energy consumption during cooler operating conditions.
• Programmable remote start: Enables the compressor to be started remotely, improving convenience and operational flexibility in larger industrial facilities.
• Auto-restart after power failure: Automatically resumes operation following a power interruption, minimising downtime and reducing the need for manual intervention.
• Integrated phase sequence relay: Protects the motor against incorrect phase sequencing, safeguarding the machine and extending its operational lifespan.
