About the Airtac GAFC Air Service Unit GAFC50020ASW
This AirTAC GAFC50020ASW is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, mounted on a shared T-bracket with quick clamps. It handles a 3/4in port and weighs 1910 g, placing it in the upper mid-range of the GAFC family, sized for a machine header rather than a single actuator.
Air enters the first body where the 5 um element removes solids and moisture, and the regulator sets pressure anywhere from 0.15 to 0.9 MPa (20-130 psi). The lubricator then adds a metered oil mist downstream, so oil never travels back through the regulator seat. The 108 cc condensate bowl and 225 cc oil bowl define the service interval, and the automatic drain clears water without an operator.

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 GAFC50020ASW Is Used
Machine tool lubrication
Feed a CNC lathe's way-lubrication system with filtered, regulated air and a consistent oil mist for slideways and bearings.
Assembly station air prep
Supply a multi-fixture assembly bench where precision pneumatic screwdrivers need clean, lubricated air at a stable pressure.
Packaging line actuation
Power a case-packing cell's pneumatic cylinders and grippers, where the 5 um element protects sensitive valves from particulate wear.
Is the Airtac GAFC Air Service Unit GAFC50020ASW the Right Air-Prep Unit?
Choose the GAFC50020ASW when your line needs 3/4in ports and a 5 um element for finer filtration. The automatic drain suits unattended operation, while the PC bowl is the standard build; confirm it fits your environment, as the catalogue gives no material-specific ratings. The fitted circular gauge reads in MPa and psi, matching the PT thread. If you need a lower pressure range, step to an L-type model, or add a reverse-flow valve with the K option. Spare parts are orderable 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 your inlet pressure accordingly 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 GAFC50020ASW FAQ
This unit 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 is rated for -5 to 70 C and uses ISO VG 32 oil. The condensate bowl holds 108 cc and the oil bowl 225 cc, with a total weight of 1910 g.
The 'A' in the code specifies an automatic drain, which expels condensate from the 108 cc bowl without manual intervention. This is ideal for lines that run continuously or in humid conditions where water buildup is frequent.
