‘ Independent flow and capacity measurements provide useful engineering information’
For Motrbee, the value of the SWRI evaluation is that it provides measurable laboratory data under a recognised test procedure.
Filtration efficiency is only one side of the equation. The filter must also allow oil to move through the lubrication system. Under the published SWRI test conditions, the MB10575 showed approximately 21kPa of flow resistance at 10 litres-per-minute. The test also reported a contaminant holding capacity of 5.14 grams.
These measurements should be understood as laboratory results under specified conditions, rather than universal numbers for every engine. Actual oil flow and restriction depend on oil viscosity, temperature, pump characteristics, engine design, operating conditions and filter loading. Nevertheless, independent flow and capacity measurements provide useful engineering information that can be considered alongside filtration efficiency.
Motrbee’ s reusable-filter heritage distinguishes it from a company that began solely with disposable spin-on filters. TRASKO’ s reusable systems used replaceable cartridges, allowing the filter housing to remain in service while the filtration element was replaced.
Motrbee continues to offer this technology through the TRASKO-branded reusable line. The TI-10SS, for example, is a reusable unit using a 3 / 4-16 thread and measuring approximately 3.5 inches in length and diameter. It uses the RK-10SS replacement kit. The company’ s cross-reference information provides applications and replacement cartridge information for a range of reusable systems.
Motrbee’ s current range of spin-on filters use 0.6mm steel housings to help survive the environment of an operating engine
