Air compressors from Refina feature pumps and motors designed for continuous site use. Refina air compressors include slow-moving engines and pumps. There are variants with capacities ranging from 24 litres to 110 litres that run on 110v, 230v, and petrol.

Air compressors convert power from various fuel engines into potential energy that is stored as pressurised or compressed air. To increase the pressure in a storage tank, a compressor will force air into it. Most are equipped with wheels, making them easy to manoeuvre. The size of the tank determines how much air is stored and how long it will run, so if tools that require a high volume of air for an extended period of time are being used, a larger tank or industrial air compressor should be considered. For smaller jobs, portable air compressors are ideal.
