3 HP single-phase, induction electric motor

Power supply: 230 V

Rated power output: 3 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.

B2800B pump unit

Air displacement: 330 l/min
Pump unit: twin-cylinder with cast iron cylinders
Type of air displacement: single-stage
Lubrication: oil
Revolutions per minute: 1570 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 level sight glass.


The Nuair B2800B/100 CM3 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

Schuko plug

Ergonomic handle

Heavy-duty plastic wheels

Swivelling front wheel

Condensate draining valve

Direct tank connector
