Airtac GAFC Air Service Unit GAFC50020ASNW
The AirTAC Airtac GAFC Air Service Unit GAFC50020ASNW 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 GAFC50020ASNW
This AirTAC F.R.L. combination pairs a filter-regulator with a lubricator on one T-bracket, so the air is cleaned, set to pressure, then oil-misted in the last stage. The GAFC50020ASNW uses a 3/4in port, weighs 1910 g, and holds 108 cc of condensate plus 225 cc of oil in two separate bowls.
The standard pressure range is 0.15-0.9 MPa (20-130 psi) with a 5 um element that traps finer particles for sensitive equipment. The automatic drain clears water without an operator, and since no gauge is fitted, the 1/4in gauge connection is ready for a later add-on if needed.

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 GAFC50020ASNW Is Used
Machine tool headers
Feeds a 3/4in header on a CNC machining center, supplying filtered and lubricated air to multiple cylinders and valves.
Assembly line lubrication
Provides regulated, oil-misted air to pneumatic actuators on a multi-station assembly conveyor, with the automatic drain reducing maintenance stops.
Packaging equipment
Supplies clean, pressure-controlled air to film-sealing and carton-erecting machines where consistent lubrication extends cylinder life.
Is the Airtac GAFC Air Service Unit GAFC50020ASNW the Right Air-Prep Unit?
Choose the GAFC500 for a 3/4in line feeding a machine header or multi-station setup; the 7000 L/min plotted flow curve at 0.7 MPa inlet shows its sizing envelope. The PC bowl is the standard build, the automatic drain suits unattended operation, and the 5 um element trades finer filtration for more frequent service. Spare parts are GAFR500-20 and GAL500-20, both orderable separately.
With no gauge supplied, the 1/4in connection accepts one later. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan the inlet pressure carefully if you need the full output.
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 GAFC50020ASNW FAQ
The working pressure range is 0.15-0.9 MPa (20-130 psi), with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. It operates from -5 to 70 C, uses ISO VG 32 oil, has a 108 cc drain bowl and 225 cc oil bowl, and weighs 1910 g.
The N after the port code means no gauge is supplied. The GAFC500 has a 1/4in gauge connection, so you can add a circular gauge later to read the set pressure directly.
