The Duro-Tank stainless steel recirculating system uses biodegradable chemistry to clean a variety of objects. This cost-effective option to large ultrasonic machines and vapor degreasers is ideal for manual parts and component cleanup. The Duro-Tank is designed for use with a washout sink and features a closed-loop recirculating system that uses progressive, multi-stage filtering to significantly extend solvent life. The system can reduce chemical consumption by as much as 80 percent, reduce disposal costs and improve worker safety. The system uses no electricity and needs only a standard compressor to power the onboard air pump, making the unit safe to use in environments where VOCs may be present.
