Q: Your Product Guide mentions Lube Oil and Hydraulic filters' by-pass setting, what is this?
A: Each lube oil filter and hydraulic filter system is equipped with a by-pass valve to ensure that main components in the system are sufficiently lubricated, independent if oil is cold or filter is blocked by excessive contamination. The by-pass valve can be located in the filter or filter head. Depending on the OEM manufacturer's specification, the setting of the by-pass valve can be different. The Cummins Filtration catalog mentions the setting of this valve (14.7 PSI = 1 bar). If no setting is mentioned, no by-pass valve is mounted in the filter.

Q: Your Product Guide mentions Lube Oil and Hydraulic filters' anti-drainback valve, what is this?
A: An anti-drainback valve is fitted in filters for applications where the risk exists that the filter is running empty. This situation has to be avoided, otherwise wear will occur on the moving parts as these parts are not yet lubricated by oil.
