The GapVax XVT is designed to vacuum-convey heavy sludges such as drilling fluid, grease, septic and wastewater. The deep vacuum power of the positive displacement blower loads quickly. The PD blower can also pressure off-load up to 14 psi (rated 1,400 cfm at 28 inches Hg). The body is constructed of 1/4-inch ASTM A-572 Grade 50 steel with a payload option from 80 to 100 barrels with a 40-degree dump angle. The filtration system consists of a 10-micron washable Dacron filter and has quick access with no tools needed. The full-opening tailgate with dual lift cylinder and field-adjustable locks ensures a complete seal. Common options include a hydroexcavation package, lift axle, integral water tank, safety lighting, storage compartments and heavy-duty rear bumper. 888/442-7829; www.gapvax.com.
