Nuair NB/5,5CT/270 twin-cylinder electric air compressor

Nuair NB/5,5 CT/270 air compressor brief overview:

NB (absorbed air: 640 l/min)

5.5 - 5.5 HP three-phase motor

270 - Tank capacity 270 L

The Nuair NB/5,5 CT/270 air compressor was designed for professionals and demanding hobby users that require a reliable, efficient and long-lasting machine.

Equipped with a 5.5 HP electric motor. Compressed air suction capacity: 640 litres per minute. Maximum pressure: 11 bar.

Fitted with a large compressed air storage tank. Tank capacity: 270 litres.

It weighs 125 kg and it is easy to move thanks to its wheels and upper handle.

Technical features

Air displacement: 640 L/min

Pump unit type: belt driven

Absorbed air: 640 L/min

Pressure: 11 bar

Electric motor power: 5.5 HP

Tank: 270 L

Overall dimensions:
- Width: 1550 mm
- Height: 590 mm
- Depth (or thickness): 1100 mm

Weight: 125 kg

5.5 HP three-phase, induction electric motor

Power supply: 400 V three-phase

Rated power output: 5.5 HP
Induction motors are very long lasting and require very little maintenance.

Brushless motor - brushes are usually subject to a fast wear and tear process when it comes to electric motors. The lack of brushes makes this motor very durable.

Extremely reliable, super quiet, long lasting. Low consumption levels and limited maintenance.

NB5 pump unit

Air displacement: 640 l/min
Pump unit: twin-cylinder with cast iron cylinders

Type of air displacement: two-stage
Lubrication: oil
Revolutions per minute: 1480 rpm

The air compressor quality level and durability depend largely on the pump rpm rate.

The lower the revolution number, the longer the compressor lifespan. Rpm rate reduction is possible thanks to the use of different diameter pulleys on the motor and pump unit.

Focus on the oil disptick and level sight glass.

Focus on the side cooling manifold that brings the output compressed air temperature down.


The NB5/5,5CT/270 Nuair air compressor controls are very simple and user friendly:

Master switch

Output air pressure gauge

Tank pressure gauge

Female air outlet

Pressure regulator

Belt drive

Belt drive is a special feature of Nuair compressors.

Belt transmission and induction motors guarantee long durability as they reduce the rpm rate drastically. This slows down and reduces the wear and tear process.

The protection grid protects the belt and the transmission system from foreign objects that may collide with them and cause damages. Moreover, you can visually check the belt at all times.

Other characteristics

Three-phase cord

Ergonomic handle

Heavy-duty plastic wheels

Swivelling front wheels

Condensate draining valve

Free items: air compressor maintenance kit with oil bottle and joints

The maintenance kit that includes:

  • 600 ml "COMPRIX” oil bottle, professional oil specifically designed for compressor heads. Perfect for oil refill and first oil replacement (the air compressor is shipped with levelled oil).
  • Air compressor spare / replacing female output joint
  • Air compressor spare / replacing male output joint (replaceable on equipment with bayonet cap) or usable as spare joint

  • Quick joint to convert all the machineries fitted with standard bayonet coupling. It allows easily connecting the units to hoses with female quick joint.

  • Quick-action coupling for the transformation of the quick coupling female supplied on the compressor in the traditional bayonet coupling (also allows use of the standard hoses with bayonet system)

  • Repair / Junction fitting for Ø 8 hoses
  • Repair / Junction fitting for Ø 10 hoses
  • Lower discharge valve
  • Teflon Roll, ideal for the main maintenance operations
