About the Airtac GAFC Air Service Unit GAFC400N10SN
This F.R.L. combination pairs a filter-regulator body with a separate lubricator, joined on a T-bracket with quick clamps. The GAFC400N10SN takes a 3/8" port, filters to 40 um, and regulates from 0.15 to 0.9 MPa (20-130 psi).
A nylon bowl protects the 100 cc condensate chamber, while the 185 cc oil reservoir feeds the lubricator. Weighing 1810 g, this unit suits a fixed panel or frame mount rather than tubing support. The two-piece design means one less inter-unit joint to seal compared to a three-body train.

Constituent units, orderable separately as spares: GAFR400-10 filter & regulator, GAL400-10 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 GAFC400N10SN Is Used
Precision Jig Fixtures
Feed a 3/8" line to a precision clamping jig on a CNC machine, where the 40 um element protects fine valve pilots and the regulated 0.15-0.9 MPa range sets workholding force.
Assembly Station Air
Supply a multi-operator assembly station with cleaned, regulated air and a metered oil mist for pneumatic screwdrivers and small cylinders, with the 185 cc oil bowl reducing refill stops.
Test Bench Supply
Use it on a component test bench where a stable 0.4 MPa setpoint is needed for cycle testing, and the semi-auto drain keeps the 100 cc bowl clear during long unattended runs.
Is the Airtac GAFC Air Service Unit GAFC400N10SN the Right Air-Prep Unit?
Choose the GAFC400N10SN when you need a 3/8" port with a 40 um element and a nylon bowl. The semi-auto drain dumps condensate on pressure drop, and the manual drain gives on-demand control. No gauge is fitted, so the 1/4" gauge connection is available if you add one later. The PT thread carries an MPa/psi scale if you fit a gauge. For oil-free lines, omit the lubricator and select a plain GAFR400-10 filter-regulator instead; the GAL400-10 lubricator is the matching spare. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan supply pressure near 1.0 MPa if you need the full regulated 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 GAFC400N10SN 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 proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C and uses ISO VG 32 lubricant. The drain bowl holds 100 cc, the oil bowl 185 cc, and the unit weighs 1810 g.
The N after the port code means no gauge is supplied. The 1/4" gauge connection is still present on the body, so you can add a circular gauge later. With a PT thread, any gauge you fit will read in MPa and psi. Without a gauge, you cannot read the set pressure directly from the unit.
