How does a compressor work?

Mostly, compressors in the tradesman's sector are devices with piston compression. This principle is easy to explain. A motor drives the piston, which moves within the cylinder. This causes the piston to suck in outside air and compresses it in the next step. The compressed air is now stored in a boiler.  If required, the valve on the boiler now allows the previously compressed air to be released precisely. Nearly all compressors have an automatic motor shut-off when the maximum air pressure is reached. A safety valve prevents the pressure in the boiler from becoming too high. The motor is reactivated as soon as the pressure in the boiler falls below a certain level.

Which air compressor for which field of application?

Depending on the requirements and the area of application, different compressors are also required. Therefore, you should always pay attention to this before the purchase is made. Many will only need a compressor for occasional checking and topping up of the tyre pressure, while others will need a compressor for professional continuous use.

For occasional use, small compressors without an air reservoir are often sufficient. For the use of pneumatic tools and for painting, however, you should consider to purchase a larger unit. Normally, air compressors with a capacity of 20-50 litres are the appropriate size in this case.

How much pressure does a compressor need?

The maximum achievable air pressure is given in bar and, in addition to the capacity of the boiler, is decisive for the possible applications with the compressor. A basic reminder is certainly helpful here. The harder the work to be done, the higher the required air pressure. However, the required air pressure is in any case always indicated on the compressed air tool. So, you are sure to find the right tool for individual needs.

Maintenance of an air compressor

Condensate is produced during the production of compressed air. It is polluted by the particles contained in the drawn-in air and should therefore be regularly drained. The compressor will enjoy a longer service life and operation runs smoothly. The condensate may only be disposed of in special waste, as it contains pollutants that must not be found in household waste. All filters in the compressor should also be cleaned regularly, or replaced if necessary.

Important: Always open the valve carefully to avoid splashing!
