3000 Series Medium Pressure Hydraulic T-Type Filter
The Norman 3000 series filter meets the need for an economical medium-pressure hydraulic filter with high flow capacity. This series is manufactured from lightweight aluminum which allows for ease of installation and maintenance. Filter elements are available in multiple media types and micron ratings. Built in-house at Norman Filter Company's Bridgeview, Illinois facility, the 3000 Series T-type housing is designed to be a cost-effective, easy-to-service alternative to heavier high-pressure assemblies — making it a popular choice for industrial plants, machine shops, and mobile/off-highway equipment builders who need reliable contamination control without the weight or cost of a stainless steel high-pressure housing.

Frequently Asked Questions
What is a medium pressure hydraulic filter?
- A medium pressure hydraulic filter removes particulate contamination from hydraulic fluid in systems operating up to roughly 800 PSI. Norman's 3000 Series uses a lightweight, anodized aluminum T-type housing, handles flows up to 150 GPM, and accepts cellulose, microglass, or stainless steel mesh elements rated from 3µm to 150µm.
What industries use the Norman 3000 Series filter?
- The 3000 Series is used in injection molding, machine tool, mobile and off-highway equipment, compressor lube oil systems, hydrostatic drive charge pumps, oil patch drilling, and servo pilot-line applications — anywhere an economical, high-flow medium pressure filter is needed.
What port sizes and pressure ratings does the 3000 Series offer?
- The 3000 Series handles 0–800 PSI and up to 150 GPM, with ¾" to 2" NPT or SAE/ORB port connections. Its anodized aluminum housing keeps the assembly lightweight while still supporting high-flow industrial and mobile hydraulic systems.
What filter elements fit the 3000 Series housing?
- 3000 Series elements are available in cellulose, microglass, and stainless steel mesh media, with micron ratings from 3µm to 150µm. Optional accessories include 25 or 50 psi bypass valves, visual or electrical cleanliness indicators, and a bowl drain.
