About the Airtac GAFC Air Service Unit GAFC40015SNK
This GAFC40015SNK is a two-piece F.R.L. combination: the filter and pressure regulator share one body, and the lubricator is mounted beside it on a T-bracket. Air enters the 1/2in port, gets cleaned by the 40 um element, and is regulated to a set pressure between 0.15-0.9 MPa (20-130 psi) before oil mist is added downstream.
The 100 cc condensate bowl and 185 cc oil bowl mean fewer service stops on a medium-size line. At 1810 g, this unit needs a proper panel or frame mount rather than tubing support. The reverse-flow (reflux) valve is fitted, and no gauge is supplied - the 1/4in gauge connection is there if you add one later.

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 GAFC40015SNK Is Used
CNC coolant lines
Feed a 1/2in line supplying coolant valves on a CNC lathe, where regulated pressure keeps flow consistent and the 100 cc bowl handles condensate between shifts.
Assembly station headers
Mount on a panel feeding a multi-operator assembly station, using the 185 cc oil bowl to lubricate several pneumatic screwdrivers from one point.
Packaging machine air prep
Prepare air for a case packer's cylinder bank, where the 6000 L/min envelope at 0.7 MPa inlet covers peak demand and the semi-auto drain suits attended operation.
Is the Airtac GAFC Air Service Unit GAFC40015SNK the Right Air-Prep Unit?
Choose the GAFC400 body for 3/8in to 1/2in lines where the GAFC300's 3500 L/min envelope at 0.7 MPa inlet feels tight. The PC bowl is the standard build; the semi-auto drain dumps condensate on pressure drops, with a manual override for on-demand draining. The 40 um element suits general shop air, while the 5 um option (W code) traps finer particles for sensitive valves. This model has no gauge, so plan to read pressure with a separate gauge on the 1/4in connection. The PT thread carries an MPa/psi scale if you fit one. The reflux valve is part of this build per the K code. Spares are the GAFR400-15 filter-regulator and GAL400-15 lubricator, both orderable separately. With a 1.0 MPa max supply, you have about 0.1 MPa above the 0.9 MPa top of the regulated range, so set your supply near maximum if you need the full band.
Quick checklist
- ✓ Body size for your peak flow (1/2" 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 100 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1810 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 GAFR400-15 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC40015SNK FAQ
This F.R.L. combination works with air only, filtering to 40 um and regulating from 0.15-0.9 MPa (20-130 psi). Maximum supply pressure is 1.0 MPa (145 psi), with a proof pressure of 1.5 MPa (215 psi). Operating temperature is -5 to 70 C. The drain bowl holds 100 cc and the oil bowl 185 cc. Use ISO VG 32 lubricant. The complete unit weighs 1810 g.
The N after the port code means no gauge is supplied, so you cannot read the set pressure directly on the unit - the 1/4in gauge connection is there if you add one. The K code indicates the reverse-flow (reflux) valve is fitted. This valve is shown as a separate symbol in the catalogue, and its detailed function is covered on a dedicated page.
