Portable Piston Compressors

Portable Oil-Less Direct-Driven Air Compressors

Compact 230V oil-less piston compressors for portable workshop, maintenance, inflation and light-duty compressed-air applications.

Compact Oil-Less Compressors for Portable Use

The Nuair range combines direct-drive oil-less pump designs with 24 or 50 litre receivers. Available models use a 230V single-phase supply and are intended for correctly matched intermittent compressed-air duties.

Compare the available models below. For tool sizing, check the individual product data and allow for actual delivered airflow, duty cycle and simultaneous demand rather than displacement alone.

Airflow note: the figures above are compressor displacement figures. For demanding air tools, size from usable delivered airflow/FAD where available rather than displacement alone.

Why Choose an Oil-Less Direct-Driven Compressor?

No Pump-Oil ChangesThe compression chamber does not rely on lubricating oil, removing routine pump-oil changes from normal ownership.
Compact Direct DriveThe motor drives the pump directly, avoiding the belt-and-pulley arrangement used on conventional belt-driven piston compressors.
Portable Receiver Sizes24 and 50 litre receiver options balance portability with stored-air capacity for intermittent demand.
230V SupplyThese models operate from a suitable 230V single-phase electrical supply.
Intermittent DutiesUseful for correctly matched inflation, maintenance, cleaning and light workshop tasks rather than continuous industrial production demand.
Simple SelectionChoose by actual air demand, pressure, receiver size, duty cycle and the electrical supply available.

24 Litre or 50 Litre Receiver?

The 24 litre OL232 and 50 litre OL232 use the same 8.1 CFM displacement pump platform. The larger 50 litre receiver stores more compressed air and can provide a larger buffer for short demand peaks, but it does not increase the compressor's continuous airflow.

Oil-Less Does Not Mean Certified Clean Air

An oil-less pump avoids lubricating oil being introduced through the compression chamber, but complete compressed-air quality still depends on intake conditions, downstream pipework, condensate management and any filtration or drying required by the application. Do not assume an oil-less portable compressor alone provides breathing, medical or process-certified air.

Portable Oil-Less Compressor FAQs

What airflow and receiver sizes are available?

The range includes one 6.4 CFM model with a 24 litre receiver and two 8.1 CFM OL232 options with 24 or 50 litre receivers.

Are all of these compressors 230V?

Yes. The models in this range are 230V single-phase compressors.

Does the 50 litre OL232 make more air than the 24 litre OL232?

No. Both OL232 versions have the same 8.1 CFM displacement. The 50 litre version simply provides more stored-air capacity.

Are oil-less compressors maintenance free?

No. They remove pump-oil servicing, but normal checks, receiver drainage and model-specific maintenance still apply.

Can you check whether one will run my air tool?

Yes. Send us the tool's airflow and pressure requirement, how long it will run and whether any other tools will operate at the same time.
