About the Airtac GAFC Air Service Unit GAFC30008ALK
This GAFC30008ALK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator on a shared T-bracket. The 1/4in port and 1020 g mass place it in the mid-size class, suited for feeding a single machine station or a small bank of cylinders. It regulates to a lower 0.15-0.4 MPa (20-58 psi) band, with a 40 um element and an automatic drain.
The filter and regulator share one housing, so air is cleaned and set to pressure before the lubricator adds a metered oil mist last. The 60 cc condensate bowl and 98 cc oil bowl set the service rhythm, and with 1.0 MPa (145 psi) max supply, there is about 0.6 MPa of headroom above the 0.4 MPa top of the regulated range. A circular gauge with an MPa/psi scale is fitted, and the reverse-flow (reflux) valve is included.

Constituent units, orderable separately as spares: GAFR300-08 filter & regulator, GAL300-08 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 GAFC30008ALK Is Used
Precision pressure setting
Set a precise 0.3 MPa for a delicate clamping fixture on a CNC machine, where the lower range gives finer adjustment than a standard regulator.
Low-pressure conveyor
Feed a light-duty conveyor drive with a controlled 0.25 MPa, keeping the belt tension gentle while the automatic drain handles condensate.
Bench test rig
Supply a lab test bench with clean, regulated air at 0.35 MPa for valve cycling tests, with the lubricator protecting the test piece.
Is the Airtac GAFC Air Service Unit GAFC30008ALK the Right Air-Prep Unit?
Choose the body and port first: this GAFC300 with a 1/4in port sits between the smaller GAFC200 (1/8in-1/4in, 590 g) and the larger GAFC400 (3/8in-1/2in, 1810 g). The PC bowl is the standard build, and the automatic drain clears condensate without an operator, which suits lines that run unattended. The L type tops out at 0.4 MPa, so if the machine may ever need more than that, step up to the S type (0.15-0.9 MPa). The 40 um element is the default; the gauge reads in MPa/psi on the PT thread. Spares are the GAFR300-08 filter-regulator and the GAL300-08 lubricator, both orderable separately. Since this set adds oil mist, choose a plain GAFR if the downstream line must stay oil-free. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, giving you room to set the regulator without hitting the ceiling.
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 GAFC30008ALK FAQ
It is a lower-pressure type, regulating from 0.15 to 0.4 MPa (20-58 psi). Max 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 drain bowl holds 60 cc and the oil bowl 98 cc, with a total weight of 1020 g. Use ISO VG 32 lubricant.
The K code specifies a reverse-flow (reflux) valve fitted to the unit. It is shown as a separate pneumatic symbol in the catalogue, and its detailed function is covered on a dedicated page. For this listing, it is an ordering difference to note when selecting the unit.
