VMAC’s VR70 Underhood Air Compressor for the 2007 GM 6.6L Duramax Diesel 4500-5500 Series truck delivers air at up to 70 cubic feet per minute or 175 pounds per square inch at a weight of less than 150 pounds (dry). A belt-driven air compressor mounted under the truck’s hood maximizes the work truck’s usable deck space and payload capacity. VMAC says its simplified bracket design and accessible mounting reduces fitting and maintenance time.
