Karcher NT 45/1 12 Gallon Self-Cleaning Wet-Dry Vacuum #11458340



Our NT 45/1 provides dependable trouble-free operation utilizing self-protecting features unlike any other commercial wet dry vacuum available on the market today.

A patented filter mechanism (TACT) allows continuous fine and coarse dust retrieval without any need to shut down for filter cleaning. This function is performed automatically by powerful reverse air pulses through the filter while the machine is in use. Suction remains constant throughout the entire job, be it drywall powder, sawdust, sandings, just about any kind of dust and debris encountered in commercial cleaning applications.

No filters or inserts to install or remove when switching from wet to dry work, or back again. Nothing for the operator to remember or forget which means no accidental damage to the machine. An electronic tank level monitor shuts the vacuum motor off completely when maximum capacity is reached, including light detergent foam.
