The OFTEC ES 18H is the top model of the electric industrial vacuum range. Its 18 kW drive runs at up to 13,000 rpm and generates a vacuum of up to -600 mbar with an air flow of 1,000 m³/h. Automatic speed control adapts the unit to the working conditions; the titanium-coated turbine impeller is extremely durable and corrosion resistant; and the self-cleaning HEPA H13 cartridge filter keeps performance constant without manual intervention. It can be supplied as a set with a fully enclosed double-flap silo and a diaphragm pump for discharging the waste water.
