GasShield® Bulk and Utility Filters

Mott High Purity Bulk and Utility Filters provide 9-log filtration of particles at 0.0015 μm resulting in particle-free gas. These bulk filters are ideally suited to the higher temperatures often encountered downstream of a purifier during heated, dry down operations.
