New 110-Gallon Reversible Drum Vac™ liquid vacuum is an ideal way to vacuum coolant, hydraulic oils, spills, sludge, tramp oil and wastewater. With the turn of a knob, the same stainless steel pump quickly empties the drum. Coolant sumps can be easily refilled, floor spills vacuumed, or contaminated liquids transferred to filtration tanks in minutes. Electrically operated all-purpose vacuums aren’t designed for use in industrial environments and, as a result, motors wear out quickly and impellers clog. The compressed air powered Drum Vac does not use electricity and has no moving parts, assuring maintenance-free operation.
