Norgren L74M-4GP-QDN Excelon Micro Fog Lubricator - G1/2

Excelon micro fog design delivers precise oil distribution using the integrated flow sensor. This approach maintains a nearly constant oil/air ratio across a wide range of flows, reducing wasted lubricant and protecting critical components such as valves and actuators from under- or over-lubrication. The result is smoother operation in general pneumatic applications and longer service intervals for equipment across manufacturing lines. Installation flexibility is a key differentiator; the L74M-4GP-QDN supports both inline and modular installation, making retrofits and expansions straightforward. By aligning with standard G1/2 piping and common mounting practices, engineers can shorten commissioning times and minimize disruption to ongoing production. The straightforward maintenance pathway helps technicians diagnose and top up lubricant quickly. Durability comes from an aluminium body and bowl, delivering robust mechanical strength while keeping weight down for easier handling. Elastomer seals made from chloroprene and nitrile resist oil exposure and temperature swings, extending seal life in tough factory environments. This rugged construction translates into lower replacement costs and fewer unplanned downtime events. Operating temperature of -34 to 80 °C and a maximum inlet pressure of 17 bar cover typical plant air conditions, enabling reliable performance across geographic regions and seasonal variations. The lubricator supports a flow of 73 dm3/sec (155 scfm) with a stated start point of 0.94 dm3/sec, ensuring lubrication is available as demand begins. The micro fog output is ideal for long piping networks where uniform distribution matters most. Maintenance is simplified by a manual drain and a metal bowl with liquid level indicator for quick status checks. The unit’s G1/2 port size aligns with widespread pneumatic hardware, reducing compatibility concerns and stock-keeping requirements. Together, these features deliver consistent performance with predictable upgrades for existing automation platforms. From an applications perspective, the Excelon L74M-4GP-QDN suits general automation, assembly lines, and bulkhead-mounted setups where inline lubrication is critical. The flow sensor and aluminium design support efficient operation, helping facilities meet reliability KPIs and compliance targets while keeping operating costs in check. Finally, industry experience shows lubrication quality directly influences energy efficiency and asset life. Adopting micro fog technology with a robust external housing minimizes maintenance cycles, reduces lubricant waste, and improves process stability across shifting demand conditions.
