Hall Pyke Capsules

Hall Pyke capsules are designed and manufactured by Critical Process for small flow and encapsulated disposable cartridge requirements. CP capsules are offered in a wide range of pleated and depth medias and offered in four grades; general, food / beverage, electronic and pharmaceutical. Each Capsule has been designed to hold the maximum amount of filter media that can be completely and effectively utilized in a capsule. CP capsules lower the cost of filtration and reduce the need for high cost metallic housings. They are well suited for liquids and gas applications with the same attention to quality, traceability, validation and testing.
