VMAC's Advanced Underhood70 air compressor system reduces fuel costs and comes with enhanced environmental features. Compact and powerful, it has a digital control system that communicates with the truck engine, allowing it to turn on and off as air is required, eliminating the need for extended idling times. A controller can limit engine speed on compressor start-up, read tank pressure and automatically adjust engine rpm as needed. The system produces 70 cfm and 175 psi. Other features include remote control plug-in capability, a heavy duty air filter with cyclone pre-filter and a USB port for collecting system diagnostic data.
