Norgren 4LF-010-000 Miniature Inline Filter 25 Micron

Product Description

The NORGREN 4LF-010-000 is a miniature inline filter designed to remove particulate contamination from compressed air and pneumatic lines. With a 25-micron filtration rating, it captures fine particles that can cause wear or malfunction in downstream components such as valves, actuators, and precision pneumatic tooling. The unit connects via flexible tube to a 0.125-inch pipe port and measures 1.58 inches in length, making it suitable for tight installations where a standard-body filter would not fit. It weighs 0.5 pounds. HVAC controls technicians, industrial maintenance mechanics, and pneumatic system installers are the typical end users for this type of component.

This filter is intended for use in miniature pneumatic circuits, instrumentation lines, and small-bore compressed air systems where space is limited and inline filtration is required. The flexible tube connection design allows it to be inserted directly into a pneumatic line without rigid fittings, simplifying routing in confined enclosures or panel-mounted assemblies. It is appropriate for both light industrial and commercial HVAC pneumatic control applications where particle contamination must be managed at the component level.

Key Features

• 25-micron filtration rating removes fine particles from compressed air lines
• Miniature body at 1.58 inches long suits tight or space-restricted installations
• Flexible tube end connections eliminate the need for rigid fittings at the connection points
• 0.125-inch pipe size fits small-bore pneumatic circuits and instrumentation lines
• Lightweight at 0.5 pounds for easy inline placement without added line stress

Compatibility

Designed as an OEM-style inline filter for miniature pneumatic systems using 0.125-inch pipe connections with flexible tube terminations. No specific compatible model numbers were provided in the available product data.

Installation Notes

Installation should be performed by a qualified pneumatic systems technician or industrial maintenance mechanic. Depressurize the pneumatic line fully before removing any existing filter or inserting this unit. Ensure the flexible tube connections are seated securely and that the line is free of sharp bends near the filter body that could restrict flow or cause stress on the connection points. Follow applicable facility safety procedures and pneumatic system codes when servicing compressed air circuits.
