Excelon Plus Oil-Fog Lubricator Sight Dome Kit
The L84C-4AP-EPN leverages oil fog lubrication to deliver heavier lubrication over short distances, which is ideal for large bore cylinders, air motors, and air tools. The integrated flow sensor maintains a nearly constant oil/air ratio across a wide range of flows, reducing variability and extending component life in high-demand lines. Its design supports inline or modular installation, enabling easy retrofits and faster line changes without costly downtime. A guarded plastic bowl with a double safety lock minimizes spills and enhances operator safety in busy production cells. Diecast aluminium body construction, a polycarbonate bowl, and nitrile rubber elastomers combine durability with chemical resistance, ensuring long service life in typical shop air environments. Operating from -10 to 60 °C and up to 10 bar inlet pressure, the lubricator suits a broad range of plants while remaining lightweight at about 0.4 kg. Mounting options include Excelon Plus general mounting brackets and Quikclamps, simplifying installation on existing lines. The 1/2" PTF port and closed-bowl drain support clean, low-maintenance operation with quick-fill compatibility through standard lubricator accessories.

FAQs
Install the L84C-4AP-EPN using standard 1/2" PTF piping. It supports inline and modular configurations, enabling easy integration with existing ducts or mounting brackets. For quick retrofits, leverage the Excelon Plus mounting kits (840024-50KIT or 840014-51KIT) and ensure the drain is connected to a safe waste path. The included flow sensor helps maintain a stable oil-air ratio across flow changes, reducing setup time and trial-and-error adjustments.
The L84C-4AP-EPN operates effectively from -10 to 60 °C (14 to 140 °F) and supports a maximum inlet pressure of 10 bar. These limits accommodate most factory floor environments while delivering consistent lubrication performance on large bore cylinders and air tools.
Yes. The Excelon Plus oil fog lubricator is specifically designed for heavier lubrication over short distances, making it well-suited for large bore cylinders, air motors, and air tools. Its oil fog approach and the 1/2" PTF port ensure reliable delivery, while the guarded bowl minimizes spills in busy lines.
The Excelon Plus family is designed to meet European conformity standards and safety expectations common in industrial automation. While the exact certification scope can vary by configuration, this model aligns with CE-style safety and protective design philosophy, and suitable variants are available for more stringent IP-rated installations as required by your plant.
The integrated flow sensor maintains a stable oil-air ratio across a wide flow range, reducing lubricant waste and improving cylinder consistency. The closed-bowl design minimizes spills, while the double safety lock adds operator protection. Inline or modular installation reduces downtime during changes or upgrades, delivering measurable improvements in uptime and lubrication reliability.
