A house is not home without a pet, here is one for your shop that will keep your Metalworking fluids clean: “ZEBRA” Muscle Flexor Coalescer.  As we continue to explore the several machines available to increase coolant life, today we pay a visit to the highly regarding Zebra product line.  Separating and removing tramp oil is key to longevity of any coolant. It is a food source for bacteria and emulsifies into metalworking fluid over time. Both of these conditions lead to the chemical breakdown of metalworking fluid and pose problems. This equipment not only separates tramp oil, it includes the added benefits of suspended particle filtration and odor control.  This is an affordable improvement for individual sump management.  Refer article link.  Warning - put on your dancing shoes before playing the video.
