Patent ID: 7303145

Claim:
A vehicle comprising: a mobile base; an electrical system secured to the base and configured to provide direct current voltage; a bulk material spraying system secured to the base and comprising: a reservoir configured to store material for spraying; a first conduit connected with the reservoir; a second conduit; a pump connected with both the first and second conduits, the pump being configured to receive material from the reservoir through the first conduit and to discharge received material through the second conduit; a purge inlet provided in fluid communication with at least one of the first and second conduits; and an air flush system secured to the base and comprising: an air compressor unit, the air compressor unit integrally comprising: a compressor including an electric motor configured to operate upon receipt of alternating current voltage; a tank provided in fluid communication with the compressor and configured to store air compressed by the compressor; and an outlet provided in fluid communication with the tank and configured to selectively dispense compressed air from the tank for passage to the purge inlet to facilitate purging of material from at least one of the first conduit, the second conduit, the pump, and the reservoir; and an inverter electrically coupled with the electrical system and with the air compressor unit, the inverter being configured to selectively convert direct current voltage from the electrical system into alternating current voltage suitable to operate the compressor.
