Flow is given as stated by the manufacturer. FAD is the actual air delivered, while intake volume (Balma, DIXAIR) is a theoretical value and can be considerably higher than FAD.
How it works
How a piston compressor works
The piston moves up and down in the cylinder, while the intake and discharge valves make sure air flows one way only – from the surroundings into the receiver.
- 01
Intake
The piston moves down, the intake valve opens and air enters the cylinder through the filter.
- 02
Compression
The piston moves up, both valves are closed, the volume shrinks and the pressure rises.
- 03
Discharge
When the cylinder pressure exceeds the receiver pressure, the discharge valve opens and air flows into the receiver.
- 04
Receiver and switch
The receiver stores air and covers demand peaks, while the pressure switch stops the compressor at the upper and restarts it at the lower pressure.
Single- or two-stage
A single-stage unit compresses air in one step to about 10 bar. A two-stage unit compresses it in two stages with intercooling – for 11 to 30 bar, with lower temperature and higher efficiency.
Oil-lubricated or oil-free
Oil-lubricated units are robust and affordable, but some oil remains in the air. Oil-free units have no oil in the compression chamber – the right choice for dentistry, laboratories and food.
Direct or belt drive
With direct drive the pump sits on the motor shaft – compact and light. A belt lowers the pump speed: less wear, lower temperature and a longer service life.
Piston or screw
Piston or screw compressor?
Both compress air, but they are built for different demand. Air volume and running time decide.
| Piston compressor | Screw compressor | |
|---|---|---|
| Air demand | occasional or intermittent | constant and high |
| Operation | with breaks; Blocair up to 100% | up to 100%, even 24/7 |
| Power | 0.34–15 kW | 2.2–290 kW |
| Pressure | up to 10 bar, two-stage up to 30 bar | 5–13 bar |
| Purchase price | lower | higher |
| Typical use | workshops, dental practices, laboratories, field work | production and industry |
If the compressor runs for several hours a day without a break, a screw compressor is usually cheaper to operate. Screw compressors →
Buying advice
How to choose a piston compressor
- 01
Air demand
Add up the consumption of the tools that run at the same time and add a 20–30% reserve. Compare it with the actual delivery (FAD), not the intake volume.
- 02
Pressure
Most air tools work at 6–7 bar; the compressor should have a 1–2 bar reserve. For truck tyres choose 15 bar, for lasers and PET 20–30 bar.
- 03
Running time
A single-stage compressor is enough for occasional work. For work lasting several hours, choose a two-stage unit or an industrial Blocair with a 100% duty cycle.
- 04
Air quality
For dentistry, laboratories, food and medicine choose an oil-free compressor with a dryer. For tools and painting, an oil-lubricated compressor with a filter is enough.
- 05
Noise
If the compressor stands in a work area, choose a quiet enclosed version – Bambi VTS, Balma FELP SILENT or cleanAIR S/ST.
- 06
Supply and receiver
Smaller compressors run on 230 V, larger ones need 400 V. A larger receiver means fewer starts and steadier pressure.
FAQ
Questions about piston compressors
Can't find the answer? Call us or send an enquiry.
What is the difference between intake volume and FAD?
Intake volume is the volume of air the pistons theoretically draw in. FAD (free air delivery) is the actual amount of air the compressor delivers at working pressure – it is always lower because of losses. Use FAD when choosing.
Do I need an oil-free compressor?
You need an oil-free compressor wherever oil in the air would put the product or health at risk: in dentistry, laboratories, food and pharmaceutical production and medicine. For air tools, an oil-lubricated compressor with a filter is enough.
Can a piston compressor run continuously?
Most piston compressors need breaks to cool down. Continuous work is what the industrial Worthington Creyssensac Blocair with a 100% duty cycle is built for; for high constant demand, choose a screw compressor.
How big should the air receiver be?
The receiver covers demand peaks and reduces the number of starts. For occasional tool use, 50–100 l is usually enough; workshops with several users need 200–500 l.
How do I maintain a piston compressor?
Drain condensate from the receiver regularly and check the oil level. Replace the intake filter, oil and belt as specified by the manufacturer. We also carry out regular servicing.
Do you also supply dryers and filters?
Yes. Besides compressors, we supply complete air treatment – filters, dryers and condensate separators. Bambi VT and VTS and Balma FELP SILENT and cleanAIR are also available with a dryer.
Do you offer service and spare parts?
Yes. We advise on selection, supply and commission the compressor, and provide regular servicing and genuine spare parts for all piston compressors in our range.
