About the Airtac GAFC Air Service Unit GAFC20008LK
The GAFC20008LK is a compact F.R.L. combination built as two units on one bracket: a filter-regulator body and a lubricator. Air enters the 1/4" port, gets filtered to 40 um and regulated to a lower pressure band of 0.15-0.4 MPa (20-58 psi), then the lubricator adds a metered oil mist downstream. The 590 g assembly suits small jigs and single actuators where space is tight.
The 25 cc condensate bowl and 36 cc oil bowl set the service rhythm, and the semi-auto drain dumps water each time pressure drops while the manual drain gives on-demand control. A circular gauge is fitted with an MPa/psi scale, and the reverse-flow (reflux) valve is included. The catalogue flow curve plots to 1750 L/min at 0.7 MPa inlet, useful for relative sizing.

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 GAFC20008LK Is Used
Precision Fixture Clamping
Feed a small pneumatic clamp on a benchtop assembly jig with regulated 0.15-0.4 MPa air, keeping force gentle on delicate parts while the lubricator protects the cylinder.
Bench-Mount Pneumatic Press
Supply a compact arbor press with filtered, regulated air at the lower pressure band, reducing the risk of over-stroking thin materials while maintaining consistent cycle force.
Lab Automation Actuator
Drive a small pick-and-place actuator in a test rig with the 1/4" port and 0.15-0.4 MPa range, where precise low-pressure control matters more than high flow.
Is the Airtac GAFC Air Service Unit GAFC20008LK the Right Air-Prep Unit?
Choose the GAFC20008LK when your circuit needs the lower 0.15-0.4 MPa (20-58 psi) band and a 1/4" port. The PC bowl is the standard build; confirm it suits your environment since the catalogue gives no material-specific ratings. The semi-auto plus manual drain pair handles condensate without power, and the fitted gauge reads in MPa/psi for the PT thread. The 40 um element is the default; step to the 5 um W option for finer filtration. The K suffix adds the reverse-flow valve, and the two spares are GAFR200-08 and GAL200-08. For oil-free lines, omit the lubricator and select a plain GAFR instead. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the 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 GAFC20008LK FAQ
The GAFC20008LK operates at 0.15-0.4 MPa (20-58 psi) with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Temperature range is -5 to 70 C, recommended lubricant is ISO VG 32, and the unit weighs 590 g. The drain bowl holds 25 cc and the oil bowl 36 cc.
The L code sets the regulated band to 0.15-0.4 MPa (20-58 psi), which suits applications needing gentle, consistent force rather than high output. The K code adds a reverse-flow valve, shown as a separate pneumatic symbol in the catalogue. The spares are GAFR200-08 and GAL200-08.
