About the Airtac GAFC Air Service Unit GAFC30008S
This GAFC30008S is a two-piece F.R.L. combination: a filter-regulator body handles filtration and pressure setting, then a lubricator on the same T-bracket meters oil mist into the air stream. The 1/4in port size and 1020 g mass place it in the mid-range class, suited to feeding a single machine station or a small bank of actuators.
The standard pressure range is 0.15-0.9 MPa (20-130 psi), with a 40 um element trapping particulates and condensed water. The 60 cc condensate bowl and 98 cc oil bowl set the service rhythm, and the semi-auto drain dumps automatically on pressure drop while the manual drain gives on-demand control. A circular gauge is fitted, reading in MPa and psi for the default PT thread.

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 GAFC30008S Is Used
Precision Fixture Clamping
Feed a single-station clamping fixture on a CNC mill, where the 1/4in port and 40 um element keep the actuating cylinders clean and the pressure stable.
Small Conveyor Drive
Power a short belt conveyor's pneumatic tensioner or brake, using the 60 cc condensate bowl to handle moisture from a humid shop line.
Bench Test Rig
Supply a lab bench test rig with regulated air for valve testing, where the 98 cc oil bowl ensures consistent lubrication for the device under test.
Is the Airtac GAFC Air Service Unit GAFC30008S the Right Air-Prep Unit?
Choose the GAFC30008S when your line needs 1/4in ports and the standard 0.15-0.9 MPa (20-130 psi) band. The PC bowl is the default build, and the semi-auto plus manual drain pair suits attended machines where an operator is present. If you need finer filtration, the W option swaps the 40 um element for 5 um, and the K option adds a reverse-flow valve. The gauge reads in MPa and psi, matching the PT thread.
Spare parts are the GAFR300-08 filter-regulator and GAL300-08 lubricator, both orderable separately. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan the inlet pressure close to 1.0 MPa if you need the full output.
Quick checklist
- ✓ Body size for your peak flow (1/4" 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 60 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1020 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 GAFR300-08 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC30008S FAQ
The GAFC30008S operates at 0.15-0.9 MPa (20-130 psi), with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It has a 60 cc condensate bowl and a 98 cc oil bowl, weighs 1020 g, and is rated for -5 to 70 C. Use ISO VG 32 oil in the lubricator.
The semi-auto drain opens automatically when the air pressure drops, releasing collected condensate, while the manual drain allows an operator to empty the 60 cc bowl on demand. This dual setup is standard on models without the A code.
