Excelon Plus micro fog lubricator, G3/8, Metal bowl closed
The Excelon micro fog technology delivers a fine mist that provides near-constant lubrication across a wide flow range, reducing wear on actuators and valves and extending equipment life. This translates to measurable uptime gains and maintenance cost reductions in high-cycle pneumatic systems, especially where long pipework is used and oil consumption must stay predictable. Inline installation capability enables rapid deployment alongside existing lines, while modular adaptability supports future expansion without reworking entire subsystems. A built-in flow sensor maintains a steady oil-to-air ratio over variable flows, improving process repeatability and shortening commissioning time for new lines. A manual drain simplifies routine servicing, minimizing downtime and eliminating the need for external power or complex controls. G3/8 port sizing and a max inlet pressure of 17 bar ensure compatibility with standard pneumatics hardware, reducing sourcing complexity. Zinc body and bowl construction offer robust durability in manufacturing environments, while elastomer materials provide compatible seals for long service life. Start point at 0.94 dm3/sec and a rated flow of 24 dm3/sec (51 scfm) give you flexible setup options to match line needs. Together, these specifications support inline, compact lubrication solutions that lower total cost of ownership in general pneumatic applications.

FAQs
To install inline, mount the lubricator on a stable support next to the actuator or regulator it serves. Connect the G3/8 port to the compressed air feed, ensure correct orientation for gravity-assisted bowl drainage, and position the unit so the manual drain is easily accessible for service. Verify the lubrication line runs to the target lubrication point and confirm electrical-free operation by ensuring no external power is required for the unit itself. After installation, perform a brief cycle test to confirm stable oil/air ratios and no leaks.
Key specs include a G3/8 port size, maximum inlet pressure of 17 bar, a flow rate of 24 dm3/sec (51 scfm), and a start point of 0.94 dm3/sec. The lubricator uses a micro fog type for fine mist lubrication and is designed for compressed air as the medium. Operating temperature ranges from -34 to 65 °C. Materials include zinc for body and bowl with chloroprene and nitrile elastomers for seals.
Yes. The micro fog design provides fine mist lubrication ideal for long pipe runs and complex piping networks, helping maintain a consistent oil-air ratio across varying flow conditions. Its inline installation and robust construction support general automation lines, reducing lubrication variance and improving overall system reliability in general pneumatic applications.
Maintenance is straightforward thanks to the manual drain, which enables easy oil flush and bowl cleaning without power or special tools. Regular checks should verify the drain seal integrity, inspect elastomer seals for wear, and ensure there are no pinhole leaks. Routine inspection helps sustain precise lubrication, minimize oil waste, and extend the service life of downstream components.
