Inteceptor Hydraulic Water Absorbing Filter elements feature specially-designed media which absorb damaging water. By also trapping solid contamination, like dirt and rust, the media protect precision hydraulic components from abrasion. As the element fills with water and plugging occurs, fluid flow slows and the filter head will go into a by-pass mode. Interceptor spin-on filters are available for virtually all applications and can be specified in 10 and 25 micron nominal ratings (3 micron is available upon request). They are engineered and manufactured under the most up-to-date quality control processes to meed or exceed original equipment specifications.
