Bio-Circle M4 Heavy-Duty Bioremediation Parts Washer

The Safer, Smarter Way to Clean Parts

Stop scrubbing parts in toxic, smelly solvents that dry out your skin and fill your shop with fumes. The Walter Bio-Circle M4 is a game-changer for welders and mechanics who need to clean greasy, oily parts before welding or assembly. This isn't just a sink; it's a living system. It uses a special liquid teeming with natural microorganisms that literally eat the oil and grease off your parts. The result? The fluid stays clean, and you never have to dump out gallons of dirty hazardous waste. It’s like having a self-cleaning parts washer that works as hard as you do.

The M4 is built for the real world. It has a massive sink area and can hold up to 485 lbs, so you can drop a heavy transmission case, a hydraulic cylinder, or a large weldment right onto the grate without worry. The fluid is heated to a comfortable 105°F, which helps cut through thick grease like butter while keeping your hands warm—no rubber gloves required. Because it uses no solvents, there are no harsh chemical smells, making your shop a much more pleasant place to work. You won't have to worry about flash rust either, as the fluid leaves a temporary corrosion-inhibiting layer on your parts.

Using the M4 is simple. Just turn it on, and the pump delivers a steady stream of cleaning fluid through the brush or the flexible nozzle. Scrub your part, and let the system do the rest. The triple-filtration system catches metal shavings and grime, preventing them from clogging the lines. If you are tired of dealing with waste haulers, safety audits, and cracked skin from solvents, the Bio-Circle M4 is the upgrade your shop needs. It’s tough, effective, and safe—letting you focus on the job, not the cleanup.
