The Aqua Miser Boss Model D115 UHP waterblaster from CESCO offers adjustable pressure from 15,000 to 40,000 psi just by using the operator color touch screen. It can remove paint and/or coatings for surface preparation. It operates the same as smaller pressure washers. When the operator squeezes the trigger, the unit ramps up slowly to the set pressure and when the trigger is released the unit returns to idle. It saves on water and diesel fuel and reduces wear and tear on the pump and hoses. It can inject sand for results much like sandblasting without generating dust, aiding cleanup and disposal. 888/772-3726; www.aquamiser.com.
