These three model numbers refer to filter elements with the same construction size and filter media; the only difference is their filtration accuracy.

 Key Features and Applications

1. High Flow Design: A single filter element delivers high flow rates, reducing filter housing size and the number of required elements, thereby lowering system cost and footprint.

2. Membrane Surface Filtration: Utilizing membrane filter media, the filter primarily captures particles on its surface, offering a high contaminant retention capacity.

3. Chemical Compatibility: Polypropylene filter media and end caps offer excellent chemical compatibility and are suitable for filtration of:

Water: Industrial water, process water, and pre-filtration

Organic solvents

Oils: Certain hydraulic and lubricating oils (compatibility verification required)

Acid and alkaline solutions (refer to the chemical compatibility table to confirm concentration and temperature)

4. Typical Applications:

Industrial Water Treatment: Pre-filtration for reverse osmosis (RO) systems.

Chemical Processes: Filtration of process fluids, catalysts, and solvents.

Electronics: Pre-filtration for ultrapure water (UPW) systems.

Paints and inks.

General Industry: Pre-filters to protect pumps, instruments, and downstream high-precision filter elements.

 Important Notes

Absolute vs. Nominal Rating: Nominal rating is a relative value, indicating the filter element's ability to remove a certain percentage (e.g., 90%-95%) of particles of a specific size. Absolute Rating provides a better guarantee of 100% interception of particles larger than this size. Absolute Rating is the more reliable indicator when selecting a filter, and specific values ​​should generally be obtained from the supplier.

Dimensions: Standard dimensions for the SS-25-178 series are typically approximately 6.6 inches (178 mm) in outer diameter and 25 inches (635 mm) in length, with a double O-ring connection (commonly found in Pall HK series housings). Be sure to check the dimensional drawing when purchasing replacements.
