Airtac GAFC Air Service Unit GAFC500N20SW
The AirTAC Airtac GAFC Air Service Unit GAFC500N20SW is a genuine two-piece F.R.L. combination — a GA-series filter & regulator and a lubricator pre-assembled on one T-shape bracket with quick mounting clamps. It has 3/4" ports, a 5 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GAFC Air Service Unit GAFC500N20SW
This AirTAC GAFC500N20SW is a two-piece F.R.L. combination built for a 3/4in line. The first body houses both the filter and the regulator, so air is cleaned and set to pressure in one step before the lubricator adds a controlled oil mist downstream. It operates across 0.15-0.9 MPa (20-130 psi) with a 5 um element for finer filtration.
The nylon bowl holds 108 cc of condensate while the separate oil bowl holds 225 cc, and the complete unit weighs 1910 g. Because the filter and regulator share one body, there is one less inter-unit joint to seal compared with a three-piece filter-regulator-lubricator train of the same port size.

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 GAFC500N20SW Is Used
Machine Tool Lubrication
Feed a CNC lathe's way-lubrication and chuck cylinder from one 3/4in header, with the 5 um element protecting precision metering valves.
Assembly Line Air Prep
Condition air for a multi-station assembly conveyor where each station has its own actuator and needs consistent pressure plus oil mist.
Hydraulic Press Pilot Air
Supply filtered, regulated air to the pilot valves of a hydraulic press, with the lubricator maintaining valve spool lubrication.
Is the Airtac GAFC Air Service Unit GAFC500N20SW the Right Air-Prep Unit?
The GAFC500 body suits 3/4in piping and its 7000 L/min flow curve at 0.7 MPa inlet is plotted for sizing. The nylon bowl is a build choice; the catalogue gives no impact or chemical data, so confirm it suits your surroundings. This model ships with both semi-auto and manual drains, a circular gauge reading MPa/psi on the PT thread, and the 5 um element. For oil-free lines, omit the lubricator and choose a plain GAFR filter-regulator instead. Spare units are orderable as GAFR500-20 and GAL500-20. With a 1.0 MPa max supply, you have about 0.1 MPa above the 0.9 MPa top of the regulated range.
Quick checklist
- ✓ Body size for your peak flow (3/4" 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 108 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1910 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 GAFR500-20 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC500N20SW FAQ
It works from 0.15-0.9 MPa (20-130 psi), with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. The temperature range is -5 to 70 C, and it takes ISO VG 32 oil. The drain bowl holds 108 cc, the oil bowl 225 cc, and the unit weighs 1910 g.
The N before the port code specifies a nylon bowl. The common specification of 1.0 MPa max and -5 to 70 C is identical across PC, metal and nylon bowls, so the choice is about your environment. Confirm nylon suits your specific conditions before ordering.
