Norgren L84C-4GP-EPN Oil Fog Lubricator - Guarded Bowl
Part Number: L84C-4GP-EPN
Quick Summary
The Norgren L84C-4GP-EPN oil fog lubricator delivers precise lubrication for compressed air systems in heavy machinery and pneumatic tools. Many maintenance teams struggle with erratic oil-to-air ratios and frequent bowl refills that slow production. Designed for inline or modular installation, it supports CE-style safety expectations and rugged service life in industrial environments. Excelon Plus design reduces weight and size while maintaining a near-constant oil/air ratio across different flows, helping you improve efficiency and reduce maintenance costs. Its sealed bowl minimizes spills and simplifies service, while a flow sensor maintains ratio stability at varied demand. Built for tough environments, its die-cast aluminium body and polycarbonate bowl withstand daily industrial use on large pneumatic tools and cylinders.

Oil fog lubrication delivers precise, continuous lubrication to large bore cylinders, air motors, and pneumatic tools. This approach reduces wear, minimizes friction, and extends tool life while keeping energy use predictable. Application: Ideal for short-distance lubrication where high throughput and dependable metering matter. Flow sensor integration ensures a nearly constant oil-to-air ratio across a wide range of flows. The result is repeatable performance, reduced oil consumption, and less maintenance overhead. This is particularly valuable in multi-station setups or variable-load lines where a consistent lubricant metering is critical for tool life and cylinder reliability. Excelon Plus design supports inline installation or modular mounting. It simplifies retrofits and reduces installation time in existing pipelines. Flexible mounting in compact spaces and new builds helps maintain clean layouts and consistent service access. Guarded plastic bowl with double safety lock enhances spill containment and operator safety. This minimizes maintenance downtime and improves compliance with workplace safety standards. The integrated design aligns with standard accessories and service kits, easing routine checks. Die-cast aluminium body with a polycarbonate bowl and nitrile elastomers deliver a robust, corrosion-resistant package. The unit's lighter weight and compact footprint ease installation in challenging spaces, with compact dimensions (height 212 mm, length 72 mm, width 70 mm) and a weight of 0.4 kg that fit tight installations.

FAQs
The L84C-4GP-EPN is designed for inline installation or modular mounting and uses a standard G1/2 port. It is compatible with Excelon Plus mounting accessories such as 840024-50KIT for general mounting and 840014-51KIT/840014-52KIT Quikclamp options. This enables straightforward retrofits and flexible integration with existing lines and downstream actuators, reducing field install time and ensuring reliable alignment.
The built-in flow sensor continuously monitors downstream demand and adjusts oil metering to maintain a near-constant oil-to-air ratio over a wide flow range. This results in repeatable lubrication, minimized oil waste, and lower maintenance overhead, especially in multi-station or variable-load configurations where lubrication needs vary during production cycles.
Yes. The Excelon Plus L84C-4GP-EPN is specifically designed for heavier lubrication needs, suitable for large bore cylinders, air motors, and demanding air tools. Its oil fog approach provides effective lubrication over short distances, supporting reliable operation of high-load components and helping to extend tool life in rigorous manufacturing or packaging environments.
Before installation, confirm regional regulatory compliance requirements such as CE marking for European markets and internal safety standards relevant to your facility. While the device is designed for safe inline operation and includes a guarded bowl, always validate compatibility with your risk assessment, safety protocols, and downstream equipment to ensure full regulatory alignment.
Expect reduced maintenance downtime and lower lubricant waste due to precise metering from the flow sensor and compact, robust construction. The Excelon Plus design minimizes service complexity with a protected bowl and accessible components, which translates to longer tool life, fewer spill incidents, and a favorable return on investment through lower lubricant consumption and shorter maintenance cycles.
