Filtration Media for the Western Filter ER151B4C20 direct interchange
Our filter media is backed by ISO 16889 multi-pass testing and other ISO/SAE test protocols and the filter is produced in an ISO Certified manufacturing facility. An ISO Certified manufacturing facility is all about quality control, consistency, responsibility, and being true to the design. Optimized microglass media is used for fine filtration, just like the Western Filter ER151B4C20 hydraulic filter to be replaced. Our microglass filters use the optimal amount of media and pleats to ensure high dirt-holding capacity. The correct number and design of pleats in the element will give you the lowest initial pressure drop. Therefore the filter will take longer to reach its change-out pressure drop which is usually 25 PSID.
Micron Rating for the Western Filter ER151B4C20 cross
This Western Filter ER151B4C20 hydraulic filter replacement element is beta-rated. The filter performance is outstanding. The Beta X = 1000 number means that for every 1000 particles of x size in the fluid only one particle will pass through the filter on average.
- 20 Micron; B20 = 200, B26.6 = 1000 equivalent to efficiency of 99.9%
Filter Collapse Pressure for the Western Filter ER151B4C20 cross reference
A filter collapse pressure of 145 PSID Collapse means that if the filter is completely clogged and the build up of pressure reaches or surpasses 145 PSID Collapse the filter may collapse and allow contamination downstream. Please use a satisfactory safety factor for the filter.
This filter is compatible with the following fluids but pressure drop will vary depending on viscosity and temperature:
- Hydraulic Fluid and Machining Fluids
- Diesel and other fuels
- Lubricating Oils and Synthetic Lubricants
