Filters and Filter Holders
Sierra stocks 47mm, 70mm, and 90mm filter holders as well as filter media for use in ongoing particulate testing. All filter holders are made of 316L Stainless Steel and meet all requirements set forth in the Federal Register. Filter element capsules are also available in 47mm and 70mm sizes. Capsules are designed to fit into an individual filter holder or into Sierra’s automatic filter changer Model MC16, MC24, MC42.

Automatic Filter Changers
Sierra’s automatic filter changers allow the engineer to stay out of the test cell during testing as several tests are done in succession.  Sierra’s automatic filter changers work seamlessly with the BG-3 to fully automate particulate collection to greatly improve testing efficiency and more importantly testing safety.  The system can hold up to 42 single or double filter cartridges.
