FAQs
The L72C-3GP-ETN supports both inline and modular installations, thanks to its standard G3/8 port and compact Excelon design. For inline setups, mount directly to the supply line using the provided fittings and ensure a clean, dry compressed air supply. For modular installations, place the lubricator adjacent to the actuator or tool group and connect via short, impedance-minimized tubing to minimize response delay and maintain a stable oil-to-air ratio.
Key performance specs include a maximum flow of 24 dm3/sec (51 scfm) and a start point at 0.47 dm3/sec. The unit handles compressed air as the medium with an inlet pressure rating up to 10 bar. These figures translate to reliable oil fog delivery across typical automation cycles while maintaining consistent lubrication at varying loads.
Yes. The Excelon L72C-3GP-ETN is designed for heavier lubrication requirements over short distances, making it well-suited for large-bore cylinders, air motors, and air tools. Its oil fog approach provides a stable oil-to-air balance, which helps protect moving components from wear and reduces maintenance needs on high-load pneumatic equipment.
The closed-bowl design minimizes oil splash and contamination, which simplifies maintenance and keeps the work area cleaner. Regular checks should still verify bowl fill level and seal integrity, and periodic replacement of elastomer seals is recommended in line with service intervals. The polycarbonate bowl is lightweight and impact resistant, contributing to overall system reliability.
Ensure clean, dry compressed air to prevent contaminant buildup that can affect oil fog formation. Verify that your system can supply up to 10 bar and accommodate the G3/8 port. Consider implementing inline filtration and regular moisture management as part of your maintenance plan to maximize the lubricator’s performance and extend tool life.
