CheckPoint designed the ST Chemical Filter to fit the niche between expensive, high-pressure chemical  filters and inexpensive, less protective Y-strainers. The ST Chemical Filter utilizes filtration qualities found in high-pressure filters, such as increased system protection and a chemically inert element. The ST filter is housed in 316 SS, with chemically inert filter elements available in 316 SS and UHMWPE . The surface areas of both the 1⁄2″ and 1″ filter elements are greater than the surface area of a typical Y-strainer, which allows for tighter filtration (as little as 40 microns) and excellent flow ratings.
