Airtac GAFC Air Service Unit GAFC500N20ASNW
The AirTAC Airtac GAFC Air Service Unit GAFC500N20ASNW 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 GAFC500N20ASNW
This GAFC500 F.R.L. combination pairs a filter-regulator body with a separate lubricator on a shared T-bracket, so the air is cleaned and set to pressure before a metered oil mist is introduced downstream. The 3/4in port and 1910 g mass put it in the mid-large size class, suited to a machine header feeding several actuators rather than a single small cylinder.
It operates across 0.15-0.9 MPa (20-130 psi) with a 5 um element that traps finer particles than the standard 40 um grade, and the automatic drain clears the 108 cc condensate bowl without an operator. The 225 cc oil bowl extends time between refills on a busy line, and the nylon bowl is a build choice - the shared -5 to 70 C and 1.0 MPa limits apply regardless of material, so confirm it suits your environment.

Constituent units, orderable separately as spares: GAFR500-20 filter & regulator, GAL500-20 lubricator — both share this body and port. A GAFC has two units, not three: the filter and the regulator are one body.

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 GAFC500N20ASNW Is Used
Precision valve control
Feed a bank of proportional valves on a packaging line where the 5 um element protects fine internal orifices from abrasive particles.
Machine tool header
Supply a 3/4in header on a CNC machining center, using the automatic drain to handle condensate from a wet compressor without daily manual attention.
Multi-station assembly
Run a multi-station conveyor system where the 225 cc oil bowl keeps lubricant available for several cylinders between shifts.
Is the Airtac GAFC Air Service Unit GAFC500N20ASNW the Right Air-Prep Unit?
Choose this GAFC500N20ASNW when the line needs 3/4in ports and a 5 um element for sensitive valves; the automatic drain suits unattended operation, while the missing gauge means the 1/4in gauge connection is left for you to fit if readout is needed. The nylon bowl is specified by the N before the port, and the PT thread carries an MPa/psi scale if you add the optional circular gauge. For oil-free air downstream, omit the lubricator and select a plain GAFR500-20 filter-regulator instead; the two units here are separately 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, so plan inlet pressure near 1.0 MPa 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 GAFC500N20ASNW 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 and uses ISO VG 32 oil in the lubricator. The drain bowl holds 108 cc and the oil bowl 225 cc, with a total weight of 1910 g.
The N after the port code means no gauge is supplied, so you cannot read the set pressure directly on the unit. The 1/4in gauge connection is present if you want to add a circular gauge later, and with the PT thread it would read in MPa/psi.
