Airtac GAFC Air Service Unit GAFC500C20SNW
The AirTAC Airtac GAFC Air Service Unit GAFC500C20SNW 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 GAFC500C20SNW
This GAFC500 F.R.L. combination pairs a filter-regulator body with a lubricator on a single T-bracket, so the air is cleaned, set to pressure, and then oil-misted in one compact line. The 3/4in port and 1910 g mass put it in the upper-middle size class, suited for feeding a machine header or a multi-station line rather than a single actuator.
The 5 um element traps fine particles for sensitive valves, while the metal bowl suits industrial environments. It regulates from 0.15 to 0.9 MPa (20-130 psi), with a max supply of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). The 108 cc condensate bowl and 225 cc oil bowl set the service rhythm, and the semi-auto drain dumps on pressure drop while the manual drain works on demand.

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 GAFC500C20SNW Is Used
Machine tool coolant systems
Feed a 3/4in header on a CNC lathe or machining center, where the 5 um element protects coolant valves and the metal bowl handles shop-floor conditions.
Multi-station assembly lines
Supply a bank of pneumatic cylinders on a pallet conveyor, using the 225 cc oil bowl to keep lubricated actuators running between shifts.
Packaging film tensioning
Regulate air for web-tension brakes on a packaging machine, where the 5 um element prevents clogging in fine-orifice tension controls.
Is the Airtac GAFC Air Service Unit GAFC500C20SNW the Right Air-Prep Unit?
Choose this GAFC500C20SNW when you need a 3/4in port with a 5 um element and no gauge. The metal bowl is a build choice, not a performance upgrade, so confirm it suits your environment. The semi-auto drain clears condensate each time pressure drops, backed by a manual drain for scheduled service. The standard type covers 0.15-0.9 MPa (20-130 psi), and the PT thread carries an MPa/psi gauge scale if you add a gauge later to the 1/4in connection. For oil-free lines, omit the lubricator and select a plain GAFR500-20 filter-regulator instead. The two units are orderable separately as GAFR500-20 and GAL500-20. With a 1.0 MPa max supply, you have about 0.1 MPa of headroom above the 0.9 MPa top of the regulated range, so plan the supply pressure accordingly.
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 GAFC500C20SNW FAQ
This F.R.L. combination operates from 0.15 to 0.9 MPa (20-130 psi), with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It works in -5 to 70 C temperatures, uses ISO VG 32 oil, has a 108 cc drain bowl and a 225 cc oil bowl, and weighs 1910 g.
The N in the code means no gauge is supplied, so you cannot read the set pressure directly. The GAFC500 body has a 1/4in gauge connection if you want to add one later. The PT thread uses an MPa/psi scale on any compatible gauge.
