About the Airtac GAFC Air Service Unit GAFC400C15AS
This AirTAC GAFC400C15AS is an F.R.L. combination that pairs a filter-regulator with a lubricator on a single T-bracket, so the air is cleaned, set to pressure, and then oil-misted in sequence. With a 1/2" port and a 1810 g mass, it is a mid-size unit for shop-floor lines that need a steady supply of lubricated air to several actuators.
The metal bowl holds 100 cc of condensate, while the separate oil bowl holds 185 cc, and the automatic drain clears water without an operator. It regulates from 0.15 to 0.9 MPa (20-130 psi) and uses a 40 um element, with a circular gauge fitted that reads in MPa/psi for the PT thread.

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 GAFC400C15AS Is Used
Machine tool lubrication
Feed a 1/2" line to a CNC lathe's tool changer, where the filter removes moisture and the lubricator keeps slide ways oiled for consistent cycling.
Assembly station air prep
Supply a multi-operator workbench with filtered, regulated air at 0.6 MPa, while the automatic drain clears condensate from a humid plant line without daily checks.
Carton sealer actuation
Run a case taper's pneumatic cylinders from this unit, using the 185 cc oil bowl to keep the valves and actuators lubricated through a long production shift.
Is the Airtac GAFC Air Service Unit GAFC400C15AS the Right Air-Prep Unit?
Choose the GAFC400C15AS when a 1/2" port line needs both filtration and pressure control plus lubrication, and the metal bowl suits environments where you prefer a non-glass body. The automatic drain handles wet lines, and the 40 um element covers general shop air; step up to the GAFC500 with a 3/4" port and 108 cc drain bowl if the line is larger. The gauge is fitted and reads MPa/psi, and the PT thread is standard; the lubricator should be filled with ISO VG 32 oil. The two units are orderable separately as the GAFR400-15 filter & regulator and the GAL400-15 lubricator. With a 1.0 MPa max supply, there is only about 0.1 MPa of headroom above the 0.9 MPa top of the regulated range, so plan the supply pressure accordingly.
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 GAFC400C15AS FAQ
The GAFC400C15AS works with air, regulates from 0.15 to 0.9 MPa (20-130 psi), and has a max pressure of 1.0 MPa (145 psi) with a proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C and should not freeze. The drain bowl holds 100 cc, the oil bowl 185 cc, and the unit weighs 1810 g. Use ISO VG 32 oil in the lubricator.
The C in the code specifies a metal bowl instead of the standard PC or optional nylon. The catalogue gives the same 1.0 MPa max pressure and -5 to 70 C range for all bowl materials, so the metal bowl is a build choice. Confirm it suits your specific environment, as no impact or chemical resistance data is published for any material.
