Van Mounted Mobile Compressors
Utility companies sometimes require the versatility of a compressor which, in addition to supplying compressed air to operate roadside equipment such as a road breaker, can also act as an electric generator for lighting purposes or as a supplier of hydraulic power. Such a unit can be mounted in a van, taking as its power source the van engine via a power take off from the main drive shaft. The compressor and generator can be under the floor of the van leaving the body free for use as a mobile workshop. There are a number of these available. Figure 3 shows diagrammatically how the various items are connected. A vehicle such as the one shown in the figure can supply 2.8 m3/min of air at 7 bar pressure and 6 kVA at a choice of voltages.
