Norgren L74C-4GP-QAQ Excelon oil fog lubricator - G1/2
Part Number: L74C-4GP-QAQ
Quick Summary
Norgren L74C-4GP-QAQ Excelon oil fog lubricator provides precise lubricant delivery for pneumatic systems in heavy equipment. Operators often struggle with maintaining a constant oil-to-air ratio across varying flow, leading to inconsistent performance and increased tool wear. This unit supports CE-compliant European installations and is compatible with SIL-rated controls and rugged enclosures for harsh environments. With inline or modular installation, a 1 litre aluminium bowl, liquid level indicator, manual drain, and quick fill nipple, it delivers reliable lubrication for large bore cylinders, air motors, and air tools while simplifying maintenance and procurement.

Feature → Business Impact → Application: The Excelon L74C design supports inline or modular installation, enabling a scalable lubrication architecture that reduces system integration time and improves maintainability across multiple machines. This translates to lower installation costs and faster deployment on new lines, especially in packaging and material handling applications where space is at a premium. Feature → Business Impact → Application: Oil fog lubrication provides heavier, more consistent lubrication over short distances, protecting large bore cylinders, air motors, and heavy-duty tools from premature wear and downtime. Use this in stamping presses and pneumatic tools where lubrication demands are higher to extend component life and reduce maintenance cycles. Feature → Business Impact → Application: A flow sensor maintains a nearly constant oil/air ratio over a wide flow range, improving process stability and reducing variability in tool performance. Ideal for multi-point lubrication schemes in automated conveyors and robotics where consistent lubrication is critical for precision operations. Feature → Business Impact → Application: The 1 L aluminium bowl with liquid level indicator and manual drain simplifies monitoring and maintenance, while the quick fill nipple speeds service in high-demand environments. This supports lean maintenance programs in automotive and food-and-beverage processing where uptime matters. Feature → Business Impact → Application: Materials (aluminium body and bowl) provide durability and corrosion resistance in humid, oily shop floors, with a G1/2 port size aligning to standard compressed-air piping. The L74C range also integrates with Excelon accessories and mounting options for flexible installations in conveyors, plant air systems, and general automation.

FAQs
Yes. The L74C-4GP-QAQ is designed for inline or modular installation within Excelon configurations. It integrates with standard G1/2 port piping and compatible Excelon accessories, enabling quick retrofits on existing lines and seamless expansion for new machinery such as large bore cylinders and air-powered tools.
Key specs include oil fog type, maximum inlet pressure of 17 bar, flow capacity of 91 dm3/sec (193 scfm), and a start point of 0.94 dm3/sec. These parameters determine how the lubricator delivers oil into the air stream and how it sustains the desired oil-to-air ratio across operating conditions.
Absolutely. The Excelon L74C-4GP-QAQ is tailored for heavier lubrication over short distances, making it ideal for large bore cylinders, air motors, and air tools. Its aluminium body and bowl provide durability in tough environments, while the flow sensor maintains consistency even under fluctuating demand.
The Excelon L74C-4GP-QAQ is designed with industry-standard expectations in mind, including CE-compliant European installations and compatibility with SIL-rated control configurations where applicable. For installation and safety compliance, reference the provided datasheet and installation guide for your region and application.
Maintenance is streamlined by a manual drain and a quick-fill nipple, plus a readable liquid level in the 1 L aluminium bowl. The constant oil/air ratio and robust materials reduce wear on tools and components, extending service life and lowering overall maintenance costs. This translates to faster line uptime and improved production efficiency.
