(caustic) washdown Filtration Systems


USPI Washdown/Caustic Washdown Stationary Inline Filtration systems (Model: 88 Stainless Steel series) are designed for use in: environments requiring water or chemical washdown. (88S-SS pictured at the left)

In a (caustic) washdown environment, standard filtration systems made from aluminum, steel, or iron can quickly rust, degrade, and fail themselves, leaving equipment unprotected. The 88 Stainless Steel series will withstand these environments, protecting your equipment to reduce maintenance and operating costs. It is easy to operate (i.e. take an oil sample, monitor filter element life, change filter elements and drain canisters) and employs a simple approach to filtering that removes both solid contaminants and moisture, leading to longer fluid and equipment life.
