About the Airtac GAFC Air Service Unit GAFC300N15ALN
This GAFC300 F.R.L. combination pairs a filter-regulator with a lubricator on a single T-bracket, so the air is cleaned and set to pressure in the first body, then receives a metered oil mist from the second. The 1/2in port and 1020 g mass place it in the mid-size class, suited to feeding a small machine station or a pair of actuators without the bulk of a larger unit.
The lower-pressure version regulates from 0.15 to 0.4 MPa (20-58 psi), which suits delicate circuits that must not see higher pressures. The nylon bowl is specified by the N code, and the 60 cc condensate bowl plus 98 cc oil bowl define how often the unit needs attention; the automatic drain clears water without an operator, and the 1/8in gauge connection is ready if a gauge is added later.

Figures are the end of the flow curve plotted in the AirTAC catalogue at 0.7 MPa inlet pressure — a sizing envelope for comparing bodies, not a rated flow. Read the catalogue curve for a real duty point. Outlet pressure falls as flow rises, so size a body with headroom above your peak demand.

Where the Airtac GAFC Air Service Unit GAFC300N15ALN Is Used
Precision assembly fixtures
Feed a clean, regulated air supply at 0.15-0.4 MPa to pneumatic clamps on a small assembly fixture, where the lower pressure range protects delicate workpieces from over-force.
Machine tool coolant valves
Supply a consistent 0.3 MPa to solenoid-operated coolant valves on a CNC lathe, with the automatic drain handling condensate from a wet compressor line without daily attention.
Laboratory air benches
Provide oil-misted air to a lab bench pneumatic actuator that needs a stable low pressure, while the nylon bowl offers a lightweight build for a compact equipment rack.
Is the Airtac GAFC Air Service Unit GAFC300N15ALN the Right Air-Prep Unit?
Choose the GAFC300N15ALN when a 1/2in port and a 0.15-0.4 MPa (20-58 psi) band fit the duty, and when an automatic drain is preferred for unattended operation. The nylon bowl is a build choice, not a performance upgrade, so confirm it suits the environment; the 40 um element handles standard shop air, while the W option would fit a 5 um element for finer filtration. The PT thread carries a MPa/psi gauge scale, and since no gauge is fitted, the set pressure cannot be read without adding one to the 1/8in connection. The lubricator must be filled with ISO VG 32 oil, and if the line must stay oil-free, choose a plain GAFR filter-regulator instead. Spare parts are the GAFR300-15 filter-regulator and the GAL300-15 lubricator, both orderable separately. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, so the regulator has ample inlet headroom to hold its setpoint.
Quick checklist
- ✓ Body size for your peak flow (1/2" here)
- ✓ Standard 0.9 MPa or lower-pressure 0.4 MPa
- ✓ Bowl material: PC (blank), Metal (C), Nylon (N)
- ✓ Drain: semi-auto + manual, or automatic
- ✓ Element 40 µm or 5 µm
- ✓ Thread & gauge scale (PT / G / NPT)
Installation & Maintenance Notes
- check Install with the airflow arrow: filter-regulator first, lubricator last.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Fill the oil bowl with ISO VG 32 or equivalent only.
- check Drain condensate before the 60 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1020 g unit on its bracket, not on the tubing.
The lubricator adds an oil mist downstream of the regulator. If any part of the line must stay oil-free, use a plain GAFR300-15 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC300N15ALN FAQ
This F.R.L. combination operates from 0.15 to 0.4 MPa (20-58 psi) with a maximum pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It works in temperatures from -5 to 70 C, uses ISO VG 32 lubricant, and has a 60 cc condensate bowl plus a 98 cc oil bowl. The unit weighs 1020 g and has a 1/2in port.
The N after the port code means no gauge is supplied with this unit. To read the outlet pressure, you would need to add a gauge to the 1/8in gauge connection on the GAFC300 body. The PT thread version uses a MPa/psi scale if you fit a compatible gauge.
