About the Airtac GAFC Air Service Unit GAFC20008SN
This GAFC20008SN is a two-piece F.R.L. combination built for a 1/4in air line. The first body houses the filter and regulator together, so the air is cleaned and set to 0.15-0.9 MPa (20-130 psi) before it reaches the lubricator. The lubricator then adds a controlled oil mist as the last step, keeping oil away from the regulator seat. With a 40 um element, it handles standard shop air duties where fine filtration is not critical.
Weighing 590 g, this compact unit suits small jigs, single actuators, or bench-mounted tooling. The 25 cc condensate bowl and 36 cc oil bowl define the service interval, so a quick visual check tells you when to drain or refill. No gauge is supplied on this version, but the 1/8in gauge connection allows one to be added later if you need to read the set pressure directly.

Constituent units, orderable separately as spares: GAFR200-08 filter & regulator, GAL200-08 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 GAFC20008SN Is Used
Bench Press Feed
Feed a small pneumatic bench press with regulated, lubricated air. The 1/4in port and 590 g weight let it mount directly on the machine frame without extra support.
Portable Tooling Cart
Equip a mobile cart that powers air tools or a torque wrench. The compact size and 25 cc drain bowl suit intermittent use where condensate builds slowly.
Single-Axis Slide
Protect a precision slide or gripper with filtered and regulated air. The 40 um element catches pipe scale, while the lubricator keeps the slide's moving parts coated.
Is the Airtac GAFC Air Service Unit GAFC20008SN the Right Air-Prep Unit?
Choose this GAFC20008SN when your machine needs a 1/4in port and a standard 0.15-0.9 MPa (20-130 psi) range. The semi-auto drain dumps condensate when pressure drops, while the manual drain gives you on-demand control. The PC bowl is the default build; confirm it suits your environment, as the catalogue lists no chemical or impact data for bowl materials. If you need finer filtration, select the W option for a 5 um element, or pick the A version for an automatic drain on unattended lines. The two units are orderable separately as GAFR200-08 and GAL200-08, so a worn bowl or element does not force a full replacement. 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.
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 25 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 590 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 GAFR200-08 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC20008SN FAQ
This F.R.L. combination works with air only. The pressure range is 0.15-0.9 MPa (20-130 psi), with a max pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C and must not freeze. The drain bowl holds 25 cc and the oil bowl holds 36 cc. Use ISO VG 32 oil in the lubricator. The complete unit weighs 590 g.
The N in the code means no gauge is supplied. The 1/8in gauge connection on the body lets you add a standard pressure gauge if you need to read the set value. Without one, you set the pressure by feel or with a test gauge, which is common on simple jigs where exact pressure is not critical.
