Purelube Absolute High Presure Filters
Purelube Absolute Discharge Filters are designed to be installed at the discharge side of 1:1, 3:1 and 5:1 ratio pneumatic pumps and will handle working pressures up to 800 PSI with 2,000 PSI typical burst pressure. A convenient visual indicator provides a warning when the filter element needs to be changed, i.e.; a 35 PSI differential pressure will cause the indicator to show “Red”. The filter head has 1” NPTF threads to minimize pressure drop and maximize fluid flow. Filter elements are easily changed by loosening the large ring collar and removing the filter housing.
PureLube absolute discharge filters are available in 8” and 13” element lengths to accommodate various flow rates, fluid viscosities and particle holding capacities. Filter elements come in a choice of 3, 5, 10 and 20 micron ratings for ISO cleanliness ratings of 16/14/12, 18/16/14, 20/18/15 and 22/19/16 respectively.

Contamination Prevention and Removal
The main objective of contamination prevention is to stop contamination from initial entry. Studies have shown that it is ten times more cost effective to prevent contamination than it is to remove it, once it is present in a system. Specific solutions include desiccant and particulate breathers, pump and shaft seals and improved storage and handling of fluids.
Several technologies exist for the removal of solid and moisture contaminants from lubrication systems. The most widely used method is filtration, due to its simplicity and cost effectiveness.
It is important to institute a contamination control program for the establishment and monitoring of appropriate target cleanliness codes for machinery, storage and dispensing of lubricants. Periodic cleaning of reservoir tanks and storage vessels, along with the installation of breathers to reduce ingression of contaminants, will serve to ensure proper maintenance of target ISO cleanliness levels.
Oil analysis can be used to track trends in determining the value of various preventive maintenance efforts.
