Overview
The Schroeder KZ1 is a 1-micron synthetic microglass filter cartridge designed for high-performance hydraulic system filtration. Part of Schroeder Industries’ proven filter element lineup, the KZ1 delivers reliable contamination removal in pressure-line applications. Its Beta 200 efficiency rating ensures that 99.5% of particles at 1 micron and larger are captured, protecting pumps, motors, and actuators from wear and failure.
Key Features
- 1-Micron Synthetic Microglass Media — removes fine contaminants while maintaining low differential pressure and extended service life
- Beta 200 Ratio — 99.5% capture efficiency at 1 micron and larger particles
- Outside-In Flow Direction — typical for pressure-line applications where fluid enters the outer pleated media surface
- Buna Seal Material — compatible with mineral HH, HL, HM, and HV hydraulic fluids
- 145 psi Collapse Rating — robust construction for standard industrial hydraulic systems
- New in Box Condition — factory-sealed and ready for immediate deployment
