Air Compressors For Sale in South Africa

By design type, the following compressors are distinguished:

• piston;
• screw.

In turn, pistons are divided into oil and oil-free. Oil compressors are optimal for pneumatic tools. They have a large resource of work – up to 5 thousand hours, but supply air with an admixture of oil. To obtain clean air, oil-free compressors are used. They are in demand in medicine, pharmaceuticals, and in everyday life – for painting work. Their service life is shorter compared to oil compressors.

Screw compressors are industrial. They have high performance, are able to work around the clock and have a large working resource.

By type of drive, compressors are:

• coaxial (with direct drive) – productive, but less reliable;
• belt – less overheat and last longer, but performance is lower.

Depending on the outlet pressure, there are 3 types of compressors:

• low pressure (5-12 bar);
• medium pressure (30-50 bar);
• high pressure (150–300 bar).

For domestic needs, it is enough to buy a low-pressure compressor. When choosing, pay attention to the following parameters:

• power (from 800 to 4000 W and above);
• productivity (average 150–500 l / min);
• maximum outlet pressure (for household models: 5–13 bar);
• receiver volume (from 6 to 500 l and higher for professional models);
• work resource.
