Cleanable Hydraulic and Engine Lubricating Oil Filters for Off-Road Applications

Environmental concerns over the use and service of traditional disposable oil filters are becoming important in filter selection for off-road equipment. This is particularly true on job sites where “zero” equipment oil leakage is demanded. However, many alternatives to traditional filters do not meet original equipment manufacturers specifications for particle removal efficiency and contaminant holding capacity. This paper discusses the operating features and performance of a new line of oil filters that can be cleaned in-place, on equipment. These new filters meet or exceed the capacity and contaminant removal efficiency of typical high performance synthetic or cellulose disposable filters. Laboratory test results of filtration performance and long term structural integrity are presented. Results of extensive, successful field testing on several types of off-road equipment will also be presented.
