Pall HC7500SUZ4H Replacement Filter Element - Cross-Reference & Specifications
Pall HC7500SUZ4H Replacement Filter Element - Cross-Reference & Specifications
Hydrafil Part Number: BF-PAL-153067-L4-1MB | Ships same day from Detroit, MI | OEM-equivalent performance
The Pall HC7500SUZ4H is a 1-micron absolute filter element - the finest available in the HC7500 series - designed for hydraulic circuits where ISO cleanliness class 14/12/9 or better is a hard requirement. At 1?m absolute, this element protects servo valves, proportional valves, and precision actuators from sub-micron contamination that passes freely through 3?m, 6?m, or 25?m elements. The Buna-N seals make it the standard-fluid choice for ultra-precision mineral oil circuits in precision machine tools, injection molding clamp circuits, and aerospace actuator test stands.
Dimensional Specifications
The BF-PAL-153067-L4-1MB matches the HC7500SUZ4H in all critical dimensions, providing a direct installation fit without modification to your existing housing.
| Specification | Value |
|---|---|
| Outer Diameter (Top) | 5.06 in |
| Outer Diameter (Bottom) | 5.06 in |
| Element Length | 6.9 in |
| Thread Size | 1.5-16 UNF |
| Collapse Rating | 100 psid |
Media & Construction
At 1 micron, the media must capture extremely fine particles while maintaining manageable differential pressure - a balance that only microglass fiber achieves at this rating:
- Filtration Media: Microglass Fiber - the only practical media for 1?m absolute service; cellulose media cannot achieve this rating without unacceptable pressure drop or bypass
- Seal Material: Buna-N (Nitrile) - correct choice for mineral oil and petroleum-based hydraulic fluid systems; resists swelling and extrusion at normal operating temperatures
- End Caps: Corrosion Resistant Steel - critical at ultra-fine ratings where any bypass path directly contaminates the downstream servo circuit
- Center Tube: Corrosion Resistant Steel - provides the structural support needed to maintain element integrity at the elevated differential pressures inherent in 1?m filtration service
Filtration Performance Rating
The BF-PAL-153067-L4-1MB achieves Bx[c=1?m] = 1000 (99.9% single-pass efficiency at 1 micron) with a multi-pass Beta value of Bx[1?m] = 200 per ISO 16889. At this micron rating, the element is removing particles invisible to the naked eye - the sub-micron contamination that abrades servo valve metering edges, causes spool stiction, and leads to position control errors in precision hydraulic systems.
1?m filtration is not a general-purpose specification - it is selected exclusively for servo valve protection circuits, proportional valve supply lines, and ultra-precision actuator applications. Differential pressure rises rapidly as the element loads; change intervals must be based on differential pressure indicator readings, not calendar time.
ISO Standards Compliance
Hydrafil elements are manufactured and tested to the same ISO standards Pall applies to OEM elements. The BF-PAL-153067-L4-1MB is tested in compliance with:
| ISO Standard | What It Tests |
|---|---|
| ISO 2941 | Collapse & burst resistance |
| ISO 2942 | Fabrication integrity & bypass valve function |
| ISO 2943 | Material compatibility with hydraulic fluids |
| ISO 3724 | Flow fatigue characteristics |
| ISO 3968 | Pressure drop vs.?flow rate characteristics |
| ISO 16889 | Multi-pass performance (Beta ratio methodology) |
About the Pall HC7500SUZ4H
The HC7500SUZ4H is Pall's 1-micron absolute version of the HC7500 series in the standard L4 (6.9 in) body length, specified for precision hydraulic circuits where fluid cleanliness directly determines equipment performance and service life. Common applications include servo-controlled machine tool spindle drives, high-precision injection molding clamp and injection circuits, CNC hydraulic clamping systems, and aerospace actuator test rigs - anywhere that servo valves or proportional valves are in the circuit and downstream contamination control is critical. The Buna-N seal makes it the correct choice for mineral oil-based systems running at these ultra-fine filtration requirements.
