Tramp Oil Separator T1

Our Tramp Oil Skimmer System Affordably Removes Tramp Oils

EdjeTech’s oil water separator system (T.O.S.S. T1) is an economical solution to maintain metalworking fluid health by eliminating tramp oil problems. The T.O.S.S. T1 is priced so that one can be put on every machine tool sump in the shop.

Oil Water Separator System (T.O.S.S. T1) Applications

EdjeTech’s T.O.S.S. T1s are found in metalworking shops on the following types of machines:

  • Grinding
  • Turning
  • General Machining Operations
  • Parts Washers
  • Chemical Waste Treatment Systems
  • Oil Water Separator System (T.O.S.S. T1) Operation
  • The air pump pulls contaminated coolant from the machine reservoir through the small 2″diameter floating skimmer
  • The fluid is then discharged into the bag filter where suspended solids are removed
  • The fluid flows through the bag and into the coalescing chamber where tramp oils and mechanically dispersed oils are split from coolant
  • The clean fluid flows out of the unit through the clean discharge hose that has been placed in the coolant reservoir.

The T.O.S.S. T1 can be run while the machine tool is in operation and requires no attention other than bag filter changes.

How does EdjeTech's T.O.S.S. work?

The CNC machine sump collects the machining coolant, particulates from the machining process, and oils from the CNC machine.  When these contaminants collect in the sump it provides an environment for bacteria and fungus growth.  The smell of the coolant comes when the dead bacteria that lays between the top of the coolant and the bottom of the tramp oil layer gets disturbed.  The dead bacteria also collect in the fines and dirt that collect at the bottom of the sump and when that is removed, the gas from the dead bacteria release producing the rancid smell.


The T.O.S.S. T1 extends the life of water-soluble oils, semi-synthetic, and synthetic based coolants by removing free floating oils, dispersed oils, loosely emulsified tramp oils and suspended solids from machine reservoirs eliminating food for bacteria to feed on or fungus to grow.


The T.O.S.S. T1 comes complete with separator tank holding the bag filter and highly efficient media pack, air pump prefilter, separator supply pump, sump skimmer with suction hose, discharge hose and adjustable tramp oil discharge coupling.

The fluid filters through the bag, removing suspended solids, and flows under the tramp oil discharge trough into highly efficient coalescing media. The media is made up of one cubic foot cubes and contains 132 square feet of surface area. The large volume of surface area in a small area is what allows for 99% separation efficiency of 20 micron oil droplets and larger on the first pass. The more area the fluid has to flow through and attract to the plastic media, the more efficient the separator. The clarified fluid from the coalescing media flows into the clean fluid chamber and is discharged from the separator via an adjustable overflow weir and typicaly back into the reservoir from where it came.

The free oils removed by the media surface to the top of the tank, flow into the tramp oil discharge trough where they gravity drain out of the system into a client provided holding container (i.e. 5 gallon pail, 55 gallon drum).

"What would you say to someone in the same situation as you? I would tell them not to bother with a belt or disc skimmer and if they really wanted to get rid of their tramp oil to call you folks."
