With the advent of Covid19, commercial businesses are looking to have their HVAC ductwork cleaned. The RAMDRIVE PTO System on this truck, shaft drives a large blower and air compressor. The suction side of the blower is connected to the building ductwork and draws the dust and dirt into the truck; the blower then discharges it into the rooftop bag- house. The compressed air powers brushes and cleaning tools. The PTO system eliminates the need for a separate engine that would add cost, complexity, and weight.
