Tramp Oil Separator  ECO-4_front view

THE ECO-4 SEPARATOR is an environmentally friendly product which very efficiently removes oil and other impurities from coolant, which not only considerably extends the coolant life but also reduces replacement and disposal costs significantly. 


COOLANT  flow through the separator is forced by a membrane pump powered by compressed air, so there is no need to connect the device to electricity.


THE SEPARATOR is manufactured of stainless steel, and being portable allows its usage at multiple machines, and it operates in a "by-pass" mode so it can be used without interrupting the operation of the machine (lathe, VMC, etc.).


DIRTY coolants are ideal breeding ground for bacteria and fungi that are responsible for the unpleasant odour and which increase the risk of machine operator infections. These problems can also be solved by using the ECO-4 SEPARATOR to clean coolant systems regularly as part of your preventative maintenance program.
