FAQs
The L74M-6AP-QRP is designed for both inline and modular installations within Excelon 73/74 series workflows. For inline setups, connect to a 3/4" PTF port and integrate with compatible shut-off valves (e.g., T74T-6AA-P1N) and porting blocks (e.g., 4316-50) as needed. For modular installations, use the Universal Bracket (4324-50) or Quikclamp variants (4314-51, 4314-52) to simplify mounting. The L74M-KIT service kit provides ongoing maintenance support, ensuring rapid field servicing and reduced downtime during upgrades or routine servicing.
Key performance specs include operating temperature from -34 to 80 °C (-30 to 176 °F) and a maximum inlet pressure of 17 bar. The lubricator provides micro fog lubrication with a flow rate of 73 dm3/sec (155 scfm) and a start point of 0.94 dm3/sec, delivering a stable oil-to-air ratio over a broad range of operating conditions for consistent tool lubrication and reduced maintenance burden.
Yes. The Excelon L74M series is engineered for long and more complex pipework, delivering fine mist lubrication ideal for extensive pneumatic networks. The inline/modular installation capability, combined with a constant oil-to-air ratio and robust aluminium construction, supports dependable performance in automated assembly lines, packaging, and material handling where consistent lubrication is critical.
Certification details are not listed in the provided data; always verify on the official datasheet or with the supplier for CE marking, SIL ratings, and IP enclosure details relevant to your application. The Excelon family is designed to meet common industry expectations, but confirm exact certifications from the datasheet before deploying in regulated environments or hazardous areas.
Maintenance for the L74M-6AP-QRP includes periodic inspection of the manual drain, bowl and body integrity, and lubricant level checks. A dedicated L74M-KIT service kit is available to streamline servicing. By maintaining precise lubrication with a stable oil-to-air ratio, facilities can reduce premature tool wear, lower lubricant consumption, and achieve a faster return on investment through extended component life and reduced downtime.
