Aro/ingersoll-rand C38121-801 Frl Unit 1/4 Npt 3-piece

Product Description

The ARO/INGERSOLL-RAND C38121-801 is a miniature three-piece Filter-Regulator-Lubricator (FRL) combination unit designed for compressed air preparation in pneumatic systems. It integrates filtration, pressure regulation, and lubrication into a single modular assembly, delivering clean, regulated, and properly lubricated air to downstream tools and equipment. The unit handles up to 150 psi supply pressure and flows up to 46 SCFM, making it suitable for a wide range of light- to medium-duty pneumatic applications. A 1/4 NPT port size and compact miniature body keep the footprint small. A pressure gauge is included for at-a-glance system monitoring. Trained pneumatic technicians and industrial maintenance professionals are the primary installers.

This FRL unit fits pneumatic control panels, production machinery, and compressed air distribution points where space is limited and air quality is critical. The miniature body style suits tight enclosures or localized point-of-use installations. The 5-micron filtration rating removes particulates before air reaches sensitive actuators, valves, or air-driven tools. The automatic drain removes accumulated condensate without manual intervention, reducing maintenance downtime. The Series 1000 modular design allows individual sections to be serviced or replaced without disturbing the full assembly.

Key Features

• Three-piece FRL configuration: filter, regulator, and lubricator in one modular unit
• 46 SCFM flow capacity with 150 psi maximum supply pressure
• 5-micron filtration rating for effective particulate removal from compressed air
• Automatic drain on polycarbonate bowl with bowl guard for safe condensate management
• Pressure gauge included with 1/8 NPT gauge port for direct system monitoring
• Modular Series 1000 construction allows component-level serviceability

Compatibility

Designed as an OEM-style replacement or new-installation FRL unit for pneumatic systems requiring 1/4 NPT connections and miniature-body FRL assemblies within the ARO/INGERSOLL-RAND Series 1000 modular product family.

Installation Notes

Installation should be performed by a qualified pneumatic technician or industrial maintenance professional familiar with compressed air system safety practices. Depressurize and lock out the compressed air supply fully before installing or servicing this unit. Mount the FRL in an upright vertical orientation with airflow direction matching the arrow or markings on the body, and ensure all NPT threaded connections are made with appropriate thread sealant. Verify supply pressure does not exceed 150 psi and that operating temperatures remain within the rated range before returning the system to service.
