The Walter Surface Technologies CleanBox Flow is the newest addition to the family of Bio-Circle manual industrial parts washing systems. Suitable for bulk cleaning small- to medium-sized parts, the compact-sized CleanBox Flow is specially designed for use with Bio-Circle CB 100, the powerful, natural water-based solvent that is biodegradable and VOC-free. This system ultimately helps contribute to a safer and healthier working environment by cost-effectively replacing the need for harsh industrial solvents.The CleanBox Flow system consists of a sink and flow-through cleaning brush, a basin and heavy duty pump that circulates through heavy oils, greases and contaminants.
