Coolant Separator – Oasis™ Portable Coalescer & Fines Filtration System

For Coolant and Other Water-based Fluids

Separating and removing tramp oil is key to the longevity of any coolant. It is a food source for bacteria and emulsifies into the coolant over time. Both of these conditions lead to the chemical breakdown of coolant and pose problems as shown in the Coolant Troubleshooting Guide in Free Resources.

The Oasis not only separates tramp oil, it includes the added benefits of suspended particle filtration and odor control. When shop floor space is at a premium or you prefer to utilize one piece of equipment over many, the Oasis™ Portable Tramp Oil Coolant Separator Coalescer & Fines Filtration System may be right for you.

How It Works

Fluid is pulled from the surface of your sump and goes into the coalescing tank. The amount of tramp oil separated by the coalescer is the amount which would normally separate via gravity within the time that it is held in the coalescer. Since the pump allows for an adjustable flow rate of 1-3 gpm, the hold time is adjustable. Operated at 1 gpm, fluid is held 20 minutes (20gal/1gpm=20min). Operated at 3 gpm, fluid is held 7 minutes (20gal/3gpm=6.6). When your coolant is fresh, it should reject tramp oils readily- one of the reasons we recommend removing tramp oil daily. It is then no longer present to emulsify into the coolant itself, requiring excessive hold time to separate it. Note that because synthetic based coolants have none, or minimal, amounts of base oil, these separate tramp oil more readily than water soluble oil products having a heavy amount of natural base oil.

Testimonial - Oasis
"I use the [portable] coalescer every day and like the overall placement of all the components. I also use the Zvac and like it too! You have good products and can call me anytime for feedback," says Dave. He is using an older model coalescer – the ADAPT, which has since been improved upon and is now the Oasis!
