About this item
Filtrec FS1 Series Suction Strainers are industrial-grade filtration components designed to submerge directly inside a hydraulic oil reservoir tank to protect the hydraulic pump from coarse debris. They prevent larger particles from damaging sensitive downstream components during initial start-ups or fluid top-offs.
