Compressors
Most automotive workshop will have an air compressor; a machine that generates compressed air. Most commonly this involves using electricity to drive a motor and pistons or screw drive to actually compress the air.
Compressed air can be used in a number of ways. In a workshop environment this may include for tyre inflation, spray painting, to power air tools such as grinders, sanders, ratchets or, of course, various air powered lifting products.
In addition to the compressors themselves, it is important to consider your requirements for drying, and storing the compressed air, depending on your specific applications.
