Overview
The Norgren L72M-3AP-QDN is an Excelon series micro-fog lubricator engineered for accurate lubrication of downstream pneumatic equipment. This model features 3/8″ NPT ports, a metal bowl with liquid level indicator, and manual drain. Micro-fog lubricators are designed for those long distance or intricate circuits, providing fine mist distribution that extends equipment service life while reducing total cost of ownership.
Key Features
- 3/8″ NPT ports for easy integration into existing air preparation systems
- Metal bowl construction with built-in liquid level indicator for visual oil monitoring
- Manual drain valve for simplified maintenance and oil level adjustment
- Micro-fog delivery mechanism suitable for high-precision applications; pneumatic actuators, valves, and devices downstream benefit from correct lubrication
- Compact Excelon L72M series design for space-constrained installations
Technical Specifications
Norgren lubricators provide accurate lubrication of downstream equipment, proven to extend the life of pneumatic equipment. The micro-fog nozzle configuration delivers optimal oil atomization for applications requiring fine lubrication control.
Typical Applications
- Long-distance pneumatic circuits requiring consistent lubrication
- Precision air tools and precision control devices
- Low-flow, intricate pneumatic systems
- Applications where equipment downtime and maintenance costs must be minimized
- Compressed air preparation stations in manufacturing and assembly lines
Compatibility & Replacements
Compatible With
- Standard pneumatic circuits operating at pressures typical for micro-fog lubricators
- Compressed air systems using ISO 4401 or equivalent ported manifolds
- Downstream air tools, actuators, and control devices
- ISO VG 32 or ISO VG 46 turbine oils (verify with system design)
Replaces / Drop-In Replacement For
Verify compatibility with your system integrator before ordering. The L72M-3AP-QDN is the standard micro-fog variant; related L72M series models with different port types (such as G3/8 BSP or other configurations) may exist but are not direct replacements.
Works With
- Standard ISO 4401 ported air preparation modules
- Pneumatic circuit assemblies using NPT or ISO metric porting
- Conventional pneumatic design tools and system integrators
- Compatible with both manual and automated lubrication circuits
