After literally four motor burnouts in less than a year, a machine shop purchased a Dual-Force Vac to replace the electric vacuum used for clean out of parts washers. In the pump mode, they now directly transfer the liquid waste into 55 gallon drums for disposal.
A company supplying industrial cleaning fluids uses Dual-Force Vacs for product delivery, and remarked that, if they dispense too much product in the customer's tank, they simply vacuum it back.
Faced with frequent floor spills, a facility processing lubricants told us that their Dual-Force Vac paid for itself in less than a month from their savings in absorbents and disposal costs.
