TRASKO Questions & Answers1039

 

1. Trasko in Brief: The Trasko Refining Unit came about when the Govt. officials of the Tokyo metropolis started exploring the possibilities of improving the maintenance of their vehicles for increasing their longevity and reducing environmental impacts. In 1985 the Trasko-Bee Corporation in a joint venture with the Subaru Motor Corporation in Japan introduced this refining unit and won an award from the Mayor of Tokyo. The manufacturing premises were expanded to establish The Trasko-Korea Co. Ltd. August 1998, LOFMR introduces the Trasko Ultra-Fine Unit for the first time and makes it available both for fleet and individual use.

 

2. How is the Trasko Oil Filter different from any other systems?

 

The Trasko unit consists of a reusable canister with built-in 36 cooling fins. Trasko traps particles by lateral dispersion. The special filter element composed of kiln-dried paper has a fine porosity that traps fine particles from flowing oil while dispersing through its permeable layers. The special pressure relief valve-nut actuates when there is a pressure build-up or a surge. The valve then redirects or bypasses the oil to circulate through the 8-10 micron mesh (The critical pressure for setting itself into a bypass mode is between 8-16 psi at the relief valve and output pressure 85-90 psi from a typical vehicle's oil pump). Thus regulating a constant pressure differential in the range of an Input/Output of 1.00 : 0.89 (i.e if the input pressure was 80 psi the output pressure from the Trasko is 71.20 psi, this slight pressure drop is actually needed so that a small flow of oil is directed through the paper filter media). When flow is least restrictive the absolute particle rating efficiency is less than a micron. Upon relief actuation the secondary efficiency is still between 8-10 microns. An efficiency rating still higher than any stock type full-flow filters. The Trasko is a hybrid filter, conditionally set as full-flow oil system for any engine and changes itself into the bypass mode when it experiences a pressure above its critical range. Regular shunt market filters are designed full flow only and if they do have a bypass valve then their bypass is without a guard and the oil flows without any filtration. The Trasko can be used also as a bypass unit, if you prefer to install it along with a regular filter on a dual remote mount. The Trasko is a highly recommended product for diesel applications as well.. See some Spot Tests.

The concept of a bypass valve in an oil filter is nothing novel - any spin-on filter you can buy has one.

Cooling fins? Not needed on a Subaru, which has an oil/water heat exchanger.

I would not install a Trasko filter as a bypass filter. That's just silly. You can get down to 1 micron with a $.50 roll of toilet paper.
