FAQs
Installation steps for the L74C-4GP-EAQ typically involve mounting the lubricator in the compressed air line, connecting the G1/2 port to the supply and outlet, and ensuring the closed-bowl drain is sealed. The Excelon design supports inline or modular configurations, enabling straightforward retrofits without extensive piping work. Verify compatibility with your actuator or tool flow requirements and secure the unit against vibration in automated lines.
Key specs include medium as compressed air, operating temperature from -34 to 80 °C (-30 to 176 °F), port size G1/2, closed-bowl drain, maximum inlet pressure of 17 bar, oil fog lubricator type, flow rating of 91 dm3/sec (193 scfm), and a start point of 0.94 dm3/sec. Materials are aluminium for both body and bowl, with elastomers in chloroprene and nitrile, supporting robust field use.
Yes. The Excelon oil fog lubrication design is intended for heavier lubrication over short distances, which benefits large bore cylinders, air motors, and air tools. The flow characteristics and robust aluminium construction help maintain consistent lubrication where higher load and faster cycles are common, contributing to longer tool life and steadier performance.
Certification details are not listed in the provided data for the L74C-4GP-EAQ. When evaluating for compliance, consult the official datasheet or contact the supplier for confirmation of CE, SIL, IP ratings, and other regulatory standards relevant to your region and application. This model is part of the Excelon range, which is designed for industrial reliability in compressed-air systems.
The closed-bowl design and oil fog delivery reduce maintenance frequency by delivering a consistent oil-to-air ratio, minimizing tool wear and fouling. Inline or modular installation speeds up upgrades, and the lightweight aluminium construction simplifies mounting. In production environments, these factors translate to lower downtime, more predictable maintenance planning, and improved process reliability over time.
