Graymills offers two series of 40kHz benchtop ultrasonic cleaners – BTU and BTV. Small footprints make these units ideal for job site “cell” cleaning applications or where space is critical. They feature self-enclosed design with stainless steel, corrosion-resistant tanks and lift-off covers. Units operate at standard 120V single-phase power. Optional stainless-steel parts baskets prevent loss of small parts and are available for all models.
The BTU bench top parts washers are available in 4 gallon, 7 gallon, and 17 gallon sizes. For additional information consult the product table below.
