About the Airtac GAFC Air Service Unit GAFC40010LK
This GAFC40010LK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, joined on a T-bracket with quick clamps. The 3/8in port and 1810 g mass place it in the mid-size class, where the 100 cc condensate bowl and 185 cc oil bowl set the service rhythm. The lower-pressure regulator is set for 0.15-0.4 MPa (20-58 psi), with a 40 um element filtering the air before the lubricator adds a metered oil mist downstream.
Air is cleaned and regulated in the first body, then the lubricator introduces oil mist last, so oil never passes back through the regulator seat. The circular gauge is fitted with an MPa/psi scale for the PT thread, and the reverse-flow (reflux) valve is included. With a 1.0 MPa (145 psi) maximum supply, the unit operates well within its proof pressure of 1.5 MPa (215 psi) across the -5 to 70 C range.

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 GAFC40010LK Is Used
Precision Pressure Setting
Set a precise 0.3 MPa (43 psi) for a delicate clamping fixture on a CNC machine, where the lower-pressure range gives finer adjustment resolution than a standard 0.9 MPa regulator.
Assembly Line Lubrication
Feed a multi-spindle nutrunner on an assembly line with filtered, regulated air and a consistent oil mist, keeping the tool's internal vanes lubricated across a full shift.
Low-Pressure Test Rig
Supply a leak-testing rig that operates at 0.2 MPa (29 psi) with clean, oil-misted air, using the 100 cc condensate bowl to handle moisture from a humid compressor line.
Is the Airtac GAFC Air Service Unit GAFC40010LK the Right Air-Prep Unit?
Choose the GAFC40010LK when your line needs regulated air at 0.15-0.4 MPa (20-58 psi) and you want the convenience of a combined filter-regulator with a lubricator. The PC bowl is the standard build, while the semi-auto drain dumps condensate on pressure drop and the manual drain works on demand. The 40 um element suits general pneumatic circuits, and the PT thread with MPa/psi gauge scale matches standard regional fittings. Since this is a lower-pressure type, confirm your machine never needs more than 0.4 MPa, or select a standard S-type unit instead. The reverse-flow valve is fitted per the K code, and the two units are separately orderable as GAFR400-10 and GAL400-10. If your line must stay oil-free, choose a plain GAFR filter-regulator without the lubricator. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, giving you a comfortable operating margin below the maximum.
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 GAFC40010LK FAQ
The GAFC40010LK operates at 0.15-0.4 MPa (20-58 psi) with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It has a 40 um element, a 100 cc drain bowl, a 185 cc oil bowl, and weighs 1810 g. The temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32.
The L type tops out at 0.4 MPa, which is about 44% of the standard type's 0.9 MPa ceiling. If your application might ever need more than 0.4 MPa, this is the wrong part. The lower range does give finer adjustment for low-pressure tasks, but the 1.0 MPa max supply still leaves 0.6 MPa of headroom above the regulated band.
