The AI-1960P N is the machine you buy when 16 gallons keeps turning into one more trip to the floor drain. Koblenz built this 19-gallon wet/dry vacuum for the crews that pull water for a living: restoration technicians on loss calls, plant maintenance departments washing down production floors, and building-service contractors who would rather empty a tank three times a shift than five. A 9-amp two-stage bypass motor, a corrosion-proof rotomolded tank and a chromed steel transport cart make it a machine that gets specified once and stays in the fleet.
Sixteen of the nineteen gallons are recoverable. The remaining headroom is what the float shut-off needs to keep water away from the motor, which is the trade every honest spec sheet in this category makes.
Built for
- Flood and leak response. Eighty-nine inches of water lift and a 1-1/2 inch hose move standing water fast, and the drain hose empties the tank at a floor drain so a technician is not hauling 130 pounds of recovered water across a finished floor.
- Wash-down in plants, kitchens and locker rooms. The rotomolded poly tank does not rust or pit the way steel drums do when they live in a wet environment day after day.
- Post-construction and renovation cleanup. Twin turbine power behind double filtration handles drywall dust and grit without loading up the motor, and durable ball bearings keep the assembly turning through long dry runs.
- Stair and multi-level buildings. The heavy-duty chromed tubular steel cart rides on 10-inch double ball-bearing rear wheels sized so one person can walk the machine up and down a stair flight.
Hospital quiet is the phrase Koblenz uses for this line, and it is not marketing filler. At 68 dB the AI-1960P N runs at roughly the level of ordinary conversation, which is what makes daytime work in a clinic, a school hallway or an occupied office tower possible at all. Crews that have been pushed out of night windows by tenant schedules end up caring about decibels a great deal.
The two-stage bypass motor is the durability story. Because cooling air bypasses the working air stream, the motor never inhales the water, dust or grit being recovered. That separation is why a commercial machine in this class survives years of the same duty that kills a single-stage shop vacuum in a season. Float shut-off protection backs it up: when the tank reaches capacity the intake closes rather than letting liquid find the motor.

Frequently asked questions
How much water will the tank actually hold?
Total capacity is 19 gallons and recoverable capacity is 16 gallons. The difference is the headroom the float shut-off requires to protect the motor.
Does it have a drain hose?
Yes. The 16 and 19 gallon models include a drain hose, so the tank can be emptied at a floor drain without tipping or lifting it.
How is this different from the 16 gallon AI-1660P N?
The AI-1960P N holds 19 gallons total and 16 recoverable versus 16 and 12, and draws 1250 watts versus 1050. Both use the same 9-amp two-stage bypass motor and 1-1/2 inch hose.
Can one person move it up stairs?
Yes. It rides on a chromed tubular steel cart with 10-inch double ball-bearing non-scuffing rear wheels sized specifically for stair transport.
Is it quiet enough to run during business hours?
At 68 dB it is roughly as loud as normal conversation, which is why this line is commonly used for daytime cleaning in occupied buildings.
