About the Airtac GAFC Air Service Unit GAFC20008L
The GAFC20008L is a compact F.R.L. combination built as two units on one T-shape bracket: a filter-regulator body that cleans and sets the air pressure, followed by a lubricator that adds a controlled oil mist. With a 1/4in port and a 590 g mass, it suits small jigs, single actuators, or short pneumatic lines where space is tight.
This lower-pressure version regulates from 0.15 to 0.4 MPa (20-58 psi), with a maximum supply of 1.0 MPa (145 psi). The 40 um element removes water and solid particles, while the 25 cc condensate bowl and 36 cc oil bowl set the service interval. The circular gauge reads in MPa and psi, and the PT thread matches the MPa/psi scale.

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 GAFC20008L Is Used
Low-Pressure Clamping
Use the GAFC20008L to supply a gentle, regulated 0.15-0.4 MPa to a small bench-top clamp or fixture, protecting delicate parts from excessive force.
Single-Actuator Control
Feed a compact cylinder that advances a guide pin or small stop on an assembly line. The 1/4in port and 590 g weight suit a machine-mounted installation.
Lab Air Supply
Provide filtered, lubricated air at a controlled low pressure to a laboratory test rig or a small pneumatic valve manifold, where precise low-force actuation is required.
Is the Airtac GAFC Air Service Unit GAFC20008L the Right Air-Prep Unit?
Choose the GAFC20008L when your circuit needs a regulated output no higher than 0.4 MPa (58 psi) - for example, light-duty clamping or low-force pneumatic control. The L type tops out at 0.4 MPa, so if the machine may ever need more pressure, select the standard S type instead. The blank bowl code specifies a polycarbonate bowl; confirm it suits your environment, as the catalogue gives no material-specific ratings.
The semi-auto drain releases condensate when pressure drops, and the manual drain works on demand. A circular gauge is fitted, graduated in MPa with a psi ring, matching the PT thread. The 5 um element (W code) is available for finer filtration. Spare parts are orderable as GAFR200-08 and GAL200-08. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, so plan the 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 GAFC20008L FAQ
The GAFC20008L is a lower-pressure F.R.L. combination with a working range of 0.15-0.4 MPa (20-58 psi). Maximum supply pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). It operates from -5 to 70 C and must not freeze. The condensate bowl holds 25 cc and the oil bowl 36 cc. Recommended lubricant is ISO VG 32. The unit weighs 590 g.
The 'L' in the model code indicates the lower-pressure regulator type, which tops out at 0.4 MPa (58 psi) instead of the standard 0.9 MPa (130 psi). This suits applications needing gentle, consistent low force. If your circuit might require higher pressure later, choose the standard 'S' type instead. The 1.0 MPa max supply leaves about 0.6 MPa of headroom above the 0.4 MPa regulated top.
