John Dow 20 Gal Fluid Evacuator with Transparent Bowl

You're pulling fluid from vehicles parked at every angle in the bay, and a tank that's hard to move or hard to read slows every one of those jobs down. The John Dow 20 Gal Fluid Evacuator gives you a 20-gallon tank on 4in swivel casters up front and 7in wheels in back, so it goes where the vehicle is instead of the other way around. Hook up the 7' suction hose and pull fluid straight from the source, or run the 10' evacuation hose when you need more reach across the bay.

The transparent bowl means you're not draining blind. You see the fluid as it comes through, so a bad batch doesn't get lost in the tank before you notice it. A sight tube on the side gives you a running level check, and the vacuum gauge keeps you from over- or under-shooting your suction. The hose guard is the detail that keeps you from replacing hoses every few months, since it stops the suction line from kinking mid-job.
