A new series of portable single and two-stage air compressors has been developed by Gomo Engineering.
The compressors, the Sitemaster 20, 30 and 40, have displacements of 5671itl min (20 ft/ min), 907 lit/ min (32ft3Imin) and 1246 lit/rain (44 ft3/min) and have been designed to be easy to manoeuvre over rough ground.
The compressors are normally powered by an industrial four-stroke petrol engine, although three-phase electric and diesel models are also available.
The automatic controls disconnect the engine for easy starting, and a pneumatic throttle senses the pressure in their receiver and slows the engine to tick-over when it reaches the set value.
