Air Compressors are quite complex machinery and consist of many different parts, as with any mechanical device there con be problems and things can go wrong. If this becomes the case with your machinery do not panic it does not mean it is useless... Compressors hold quite a big market for spare parts, they are quite easy to come across and if you look in correct place not to costly either. Why replace a whole expensive unit when you can simply replace the damaged parts. Below is a list of some of the parts you may require in case of system failure:

Pressure Gauges: If your pressure gauge malfunctions / breaks your compressor essentially become useless, you can not blow air into a device without knowing how much is going in, this could potentially ruin what the compressor is attached to. There is no need to get a new compressor though as these parts are widely available and can be picked up for as little as 7.95 Franks.

Pressure Switch: An essential component and slightly harder and more costly to replace then the Pressure Gauges, still not a lost cause and can be picked up for about 22.99 Franks however you may require some one else to fit this part for you.

Air Lines with Couplings: If the line air is passed through has become damaged, these can also be replaced with ease, they can be manufactured with up to 10mm bore size and can be fitted yourself simply by unscrewing and replacing it with the new air line.

There are many other parts out there air filters being one of the most common to go, have a look around and you will find the part you need at a reasonable price.
