MacNeil’s Magnum Series Prep Gun features high pressure spray that loosens tough, caked-on dirt and grime with ease. The 7.5 horsepower Hydra-Cell pump supplies two prep guns with 1000 psi at 8 gpm, meaning you are able to have two workers prep vehicles at the same time. The non-weep trigger gun delivers up to 4 gpm at 1000 psi, and is ergonomically designed to minimize fatigue. The system includes a programmable on/off timer and utilizes a direct drive pump with an elastomeric coupler to absorb any shock between the motor and the pump itself. Also available with Hydrominder for automatic mixing.
