Norgren L74M-4GP-EPQ Excelon micro fog lubricator - G1/2
Part Number: L74M-4GP-EPQ
Quick Summary
Excelon micro fog lubricator delivers precise oil mist for general pneumatic lubrication in automation lines. Many plants struggle with inconsistent oil/air ratios, leading to wear and unplanned maintenance. The Excelon family typically supports CE safety expectations, with rugged enclosure options and, on select variants, SIL reliability and IP-rated configurations. This combination helps improve reliability, reduce downtime, and lower lubrication costs in inline or modular installations. Designed for inline or modular installation, it adapts to long or complex piping and maintains a near-constant oil/air balance across a wide flow range, enabling predictable performance in general purpose pneumatic systems.

FAQs
The L74M-4GP-EPQ is designed for inline or modular installation within the Excelon 73/74 system family. It uses a standard G1/2 port and is compatible with common Excelon mounting accessories, such as the 4324-50 universal bracket and 4314 series clamps, enabling quick integration into new builds or retrofits without major rework.
Key performance figures include a maximum flow of 73 dm3/sec (155 scfm) with a defined start point at 0.94 dm3/sec. The micro fog design provides a near-constant oil/air ratio over a wide range of flows, improving predictability and reducing lubricants waste in general pneumatic circuits.
Operating temperature ranges from -34 to 50 °C (-30 to 122 °F), and the unit supports a maximum inlet pressure of 10 bar. These specs make it suitable for typical shop-floor environments and most general pneumatic applications, including longer piping runs.
Yes. The Excelon 3/2 modular shut-off valve (example: T74T-4GA-P1N) and porting blocks (4316-50) are designed to integrate with the L74M-4GP-EPQ, enabling streamlined system configurations. Look for compatible fittings and mounting hardware within the Excelon accessory ecosystem to maximize modularity.
A dedicated service kit (L74M-KIT) is available to simplify routine maintenance, replace elastomer seals, and refresh components. Regular inspection of the bowl cover and quick-fill nipple, along with ensuring the guard is in place, helps sustain safe operation and consistent lubrication performance.
