Norgren Excelon Modular System 03
Micro-Fog Lubricators
The L72M Series air line lubricators are designed for use as a single
in-line unit or as part of Norgren’s Excelon® modular compressed air
preparation supply system. As a modular component, this pneumatic
lubricator can quickly be attached to air regulators, lters, smooth
start/exhaust valves, safety lockout valves and pipe adaptors. With ows
QuikclampTM and wall bracket accessories, a complete compressed air supply system can be assembled and mounted in minutes. L72M lubricators come in micro-fog models for pneumatic applications with one or more points of lubrication. Uses include lubrication of cylinders and air driven devices like airline tools or pneumatic screwdrivers.
• Highly visible, prismatic liquid level indicator lens on metal bowls
• All round (360°) visibility of sight-feed dome for ease of drip rate setting
• In-Line or modular installation
• Quick release bayonet bowl
• Micro-fog and oil-fog
• Flow sensor provides a nearly constant oil/air ratio over a wide range of

Soft Start/Dump Valves
The P72F Series soft start/dump valves are designed for use as a single in-line unit or as part of Norgren’s Excelon® modular compressed air preparation supply system. As a modular component, the valve
can quickly be attached to lters, lubricators, safety lockout valves
and pipe adaptors. With QuikclampTM and wall bracket accessories,
a complete compressed air supply system can be assembled and mounted in minutes. The soft start valve controls the start up and shut down of pneumatic air supply by quickly controlling the air pressure to eliminate the hammering effect of sudden air pressure to pneumatic equipment. The dump valve blocks the inlet air supply and exhausts the downstream air when the pilot supply signal is removed.

• Excelon® design allows in-line or modular installation • Solenoid pilot or air pilot operation
• Designed primarily for equipment start-up & shutdown • Manual slide can be padlocked in closed position
• Blocks inlet air and exhausts downstream air when pilot signal is removed or when the optional manual lockout slide is closed
• Controls increase of downstream pressure on start up. Cylinders and other air operated devices are eased into normal operating
• positions, reducing the possibility of equipment damage and hazards to the user
