About the Airtac GAFC Air Service Unit GAFC400C15SNK
This GAFC400 unit combines a filter-regulator and a lubricator on a single T-bracket, so the air is cleaned, set to pressure, and then given a metered oil mist in one compact assembly. The 1/2in port and 1810 g weight place it in the mid-size class, suited for feeding a multi-station machine header or a bank of actuators.
The metal bowl (C code) holds 100 cc of condensate, while the oil bowl holds 185 cc, and the 40 um element handles standard shop air. It operates from 0.15 to 0.9 MPa (20-130 psi) with a max supply of 1.0 MPa (145 psi), and the reverse-flow valve is fitted per the K code.

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 GAFC400C15SNK Is Used
Machine tool coolant systems
Feed a 1/2in header supplying coolant valves and cylinder actuators on a CNC lathe, where the metal bowl resists accidental knocks and the 100 cc condensate bowl handles a shift of moisture.
Assembly line pallet stops
Power a series of pallet stops and locating pins on an automated assembly line, using the 0.15-0.9 MPa range to set precise clamping pressure and the lubricator to keep slide valves cycling.
Packaging machine air circuits
Run a carton erector's film-seal cylinders and glue applicator valves, where the 185 cc oil bowl keeps the lubricator topped up between shifts and the semi-auto drain clears water from compressed air.
Is the Airtac GAFC Air Service Unit GAFC400C15SNK the Right Air-Prep Unit?
Choose this GAFC400C15SNK when you need a 1/2in port with a metal bowl and no gauge. The metal bowl is a build choice for your environment, but the catalogue gives no impact or chemical data, so confirm it suits your surroundings. The semi-auto drain dumps condensate on each pressure drop, and the manual drain gives on-demand control. The 40 um element is the standard grade; step to the 5 um W code for finer filtration if your valves need it. The PT thread uses an MPa/psi gauge scale, but this unit ships without a gauge, so the 1/4in gauge connection is ready for one you add. The reverse-flow valve is fitted as an ordering difference. 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 of headroom above the 0.9 MPa top of the regulated range, so plan your inlet pressure if you need to run near the ceiling.
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 GAFC400C15SNK FAQ
The working pressure range is 0.15-0.9 MPa (20-130 psi), with a max pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C and must not freeze. The drain bowl holds 100 cc and the oil bowl holds 185 cc. Use ISO VG 32 oil in the lubricator. The complete unit weighs 1810 g.
The C code specifies a metal bowl, which is a build choice for your environment, though the catalogue gives no impact or chemical data, so confirm it suits your conditions. The N after the port code means no gauge is supplied, but the 1/4in gauge connection is ready for one you add later. The reverse-flow valve is fitted per the K code.
