Combination JetVac
The GapVax MC Series unit, Combination JetVac, is a wet-only machine, equipped with a unitized water and debris tank and double sub-frame. Heavy-duty double acting single-lift cylinder provides a stable 50 degree dump angle. The MC series is also equipped with an 8' front-mounted, telescopic boom with dual lift cylinders, reaching 26' with a 180 degree rotation. With a wide variety of sizes available, this is an ideal candidate for any size municipality, water and sewer district, or contractor who is cleaning storm drains, catch basins and/or sewers.
GapVax offers a single-axle and a double-axle model. The smaller Combo unit gives you the choice of a 4-8 cubic yard debris body and a water tank capacity of 500-1,200 gallons. The Double Axle MC allows for a 8-13 cubic yard debris body and water tank of up to 2,000 gallons. Our custom-built units allow for various configurations to make for happy customers.
