Gallon
"TANK SIZE" refers to the actual tank volume, and does not reect capacity available during
operation.
PEAK HP
"PEAK HORSEPOWER" is a term used in the wet-dry vac industry for consumer comparison
purposes. It does not denote the operational horsepower output of a wet-dry vac, but rather the
horsepower output of a motor, including the motor’s inertial contribution, achieved in laboratory
testing. In actual use, motors do not operate at the peak horsepower shown.
