About the Airtac GAFC Air Service Unit GAFC400N10LK
This GAFC400N10LK 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 place it in the mid-range class, sized for a machine header feeding several actuators. It regulates from 0.15 to 0.4 MPa (20-58 psi), with the 40 um element filtering supply air before the lubricator meters oil mist downstream.
The nylon bowl holds 100 cc of condensate, while the separate 185 cc oil bowl extends time between refills. The circular gauge reads MPa/psi, and the semi-auto drain dumps condensate on pressure drops with a manual backup. A reverse-flow valve is fitted, and the catalogue shows it as a separate pneumatic symbol.

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 GAFC400N10LK Is Used
Precision pressure setting
Set a lathe's air chuck to exactly 0.3 MPa (43 psi) using the circular gauge, with the lower-pressure range giving finer adjustment than a standard 0.9 MPa regulator.
Machine header supply
Feed a 3/8in header on a small assembly station, where the 185 cc oil bowl keeps three pneumatic screwdrivers lubricated across a full shift.
Bench test rig
Supply a test fixture that cycles a cylinder at 0.35 MPa (51 psi), relying on the semi-auto drain to clear condensate from the 100 cc bowl between test runs.
Is the Airtac GAFC Air Service Unit GAFC400N10LK the Right Air-Prep Unit?
Choose this GAFC400N10LK when your line needs lower regulated pressure up to 0.4 MPa (20-58 psi) and the 3/8in port matches your manifold. The nylon bowl is a material choice, not a performance upgrade - the 1.0 MPa max and -5 to 70 C range are identical across bowl options, so confirm nylon suits your environment. The semi-auto drain handles condensate automatically on each pressure drop, with a manual drain for scheduled service. The 40 um element is the standard grade; step to the 5 um W option if you feed precision valves. The PT thread carries a gauge reading MPa/psi, and the K suffix adds the reverse-flow valve. Spares are GAFR400-10 and GAL400-10, both orderable separately. With a 1.0 MPa max supply, you have about 0.6 MPa above the 0.4 MPa top of the regulated band, so set the supply near 1.0 MPa if you need the full range.
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 GAFC400N10LK FAQ
This lower-pressure unit regulates from 0.15 to 0.4 MPa (20-58 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, uses ISO VG 32 lubricant, and weighs 1810 g. The drain bowl holds 100 cc and the oil bowl 185 cc, with a 40 um element and a fitted gauge reading MPa/psi.
The K suffix specifies the reverse-flow (reflux) valve, which the AirTAC catalogue draws as a separate pneumatic symbol. It is fitted as an ordering option on this GAFC400N10LK; the catalogue defers functional details to its own page, so confirm the valve's role for your circuit from the datasheet.
