About the Airtac GAFC Air Service Unit GAFC400N10AS
This GAFC400N10AS is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator on a shared T-bracket. The 3/8in port and 1810 g mass put it in the mid-size class, suited for machine headers feeding several actuators. Air is cleaned and set to pressure in the first body, then the lubricator adds a metered oil mist downstream, so oil never travels back through the regulator seat.
The nylon bowl holds 100 cc of condensate and the oil bowl 185 cc, which sets the service rhythm for this unit. The standard pressure range is 0.15-0.9 MPa (20-130 psi) with a 40 um element. A circular gauge is fitted, graduated in MPa with a psi ring, matching the PT thread. The automatic drain clears condensate without an operator, useful for lines that run unattended.

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 GAFC400N10AS Is Used
CNC coolant systems
Feed a 3/8in line to a CNC machine's coolant valve manifold, where the automatic drain keeps condensate from reaching solenoid pilots during long unattended runs.
Assembly station headers
Supply a multi-station assembly bench with filtered, regulated air at 0.6 MPa for pneumatic screwdrivers and push cylinders, with the 185 cc oil bowl keeping misters filled through a shift.
Packaging line actuators
Run a carton-erecting machine's cylinder bank from this unit, using the 100 cc condensate bowl as a visual service cue between weekly maintenance rounds.
Is the Airtac GAFC Air Service Unit GAFC400N10AS the Right Air-Prep Unit?
Choose the GAFC400N10AS when a 3/8in port and mid-size flow envelope are right for the line. The nylon bowl is a build choice; the common specification of 1.0 MPa max and -5 to 70 C applies to all bowl materials, so confirm nylon suits your surroundings. The automatic drain handles wet lines without manual attention, while the 40 um element covers general shop air; step to the 5 um element if you need finer filtration for sensitive valves. The PT thread carries a gauge reading MPa/psi, so operators read the set pressure directly on the fitted dial. If the line must stay oil-free, omit the lubricator and choose a plain GAFR400-10 filter-regulator instead; otherwise the GAL400-10 lubricator is the matching spare alongside the GAFR400-10. With a 1.0 MPa max supply, there is about 0.1 MPa of headroom above the 0.9 MPa top of the regulated range, so plan the supply pressure near the maximum if you need the full output.
Quick checklist
- ✓ Body size for your peak flow (3/8" 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 GAFR400-10 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC400N10AS FAQ
The GAFC400N10AS operates on air with a standard pressure range of 0.15-0.9 MPa (20-130 psi), a max pressure of 1.0 MPa (145 psi), and a proof pressure of 1.5 MPa (215 psi). It works in -5 to 70 C temperatures and requires ISO VG 32 lubricant. The drain bowl holds 100 cc and the oil bowl 185 cc, with a total weight of 1810 g.
The A code specifies an automatic drain, which expels condensate from the 100 cc bowl without an operator. This is different from the blank drain option that includes both semi-auto and manual drains. The automatic version suits installations where the unit is mounted in a hard-to-reach spot or runs continuously.
