Norgren L22-400-OP8A Oil Fog Lubricator - NACE MR-0175
Part Number: L22-400-OP8A
Quick Summary
L22-400-OP8A oil fog lubricator from Norgren provides precise lubrication for compressed air systems in demanding industrial environments. Engineers often struggle with bowl leaks, inconsistent oil-to-air ratios, and maintenance downtime that erode system performance. This unit complies with NACE MR-0175, features a stainless steel body and bowl for corrosion resistance, and uses a closed-bowl drain to minimize contamination. The compact 1/2" port fits standard piping in many facilities, while the robust build supports long service life and predictable maintenance windows. By reducing variability in lubrication and downtime, it delivers measurable efficiency gains and helps ensure regulatory compliance in harsh environments. Rugged construction also simplifies procurement and installation across multiple lines.

Ported Wall Bracket for 22 Series
Stainless steel body and bowl deliver rugged longevity in corrosive environments. This design lowers maintenance costs and extends service life, reducing unplanned downtime in offshore, petrochemical, and food-processing facilities. In practice, the L22-400-OP8A resists salt spray, humidity, and aggressive aerosols while supporting high-duty cycles.Flow performance and start point: Flow is rated at 48 dm3/sec (102 scfm) with a defined start point at 1.7 dm3/sec, maintaining a nearly constant oil-to-air ratio across operating ranges. This stability improves component wear patterns and compressor loading, delivering energy savings in continuous production lines.Closed bowl design: The closed bowl minimizes oil splash and contamination, enhancing reliability in dusty or dirty environments. It also simplifies drain maintenance and reduces spill risk during service.Compatibility and mounting: Port size 1/2" PTF aligns with standard international fittings, and the 22 Series can be mounted with the 18-001-962 Ported Wall Bracket. This enables quick installation and eliminates misalignment.Materials and compliance: Materials - body and bowl are stainless steel; elastomers are synthetic rubber, offering chemical resistance and longer gasket life. Compliance: NACE MR-0175, 2002 revision.Operational economics: Incorporating this lubricator reduces oil consumption variability and maintenance intervals, delivering a lower total cost of ownership for manufacturers with continuous air supply.

FAQs
Install the L22-400-OP8A onto a standard 1/2" PTF port using compatible fittings. Mount the unit using the Ported Wall Bracket for 22 Series (18-001-962) to ensure proper alignment and stability. Verify a closed-bowl drain is oriented to prevent leaks, then connect the air feed and oil supply lines following the datasheet installation guide.
Key specs include medium: compressed air; port size: 1/2" PTF; maximum inlet pressure: 17 bar; flow: 48 dm3/sec (102 scfm); start point: 1.7 dm3/sec; materials: stainless steel body and bowl; drain type: closed bowl; operating temperature: -20 to 80 °C. These values support stable, oil-rich lubrication across typical industrial processes.
Yes. The L22-400-OP8A is specified with NACE MR-0175, 2002 revision, aligning with offshore and corrosive environments. Its stainless steel construction and closed-bowl design further enhance corrosion resistance and spill containment, making it a robust choice for challenging facilities while maintaining compliant lubrication performance.
Maintenance is typically minimal due to the closed-bowl design, reducing contamination risk. Regular checks should confirm the bowl integrity, elastomer seals, and oil feed continuity. Schedule routine inspections for wear, replace elastomer components as recommended in the datasheet, and verify drain operation during service to prevent leaks and ensure reliable lubrication.
Expect reduced oil wastage from a stable oil-to-air ratio, lower downtime due to fewer leaks and spills, and longer intervals between maintenance with corrosion-resistant stainless steel parts. These factors collectively improve asset availability, extend compressor life, and lower total cost of ownership in continuous production environments.
