About the Airtac GAFC Air Service Unit GAFC40015LNW
This lower-pressure F.R.L. combination pairs a filter-regulator with a lubricator on one T-shape bracket, so the air is cleaned, set to 0.15-0.4 MPa (20-58 psi), then given a metered oil mist as the last step. The GAFC400 body takes a 1/2in port and carries a 5 um element that traps fine particles for sensitive equipment.
The 100 cc condensate bowl and 185 cc oil bowl set the service rhythm, and the 1810 g mass shows this is a panel-mounted unit, not something supported by the tubing. No gauge is supplied, so the 1/4in gauge connection is where an operator would add one to read the set pressure.

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 GAFC40015LNW Is Used
Precision Fixture Clamping
Feed a 1/2in line to a pneumatic fixture that clamps delicate parts during CNC machining. The 5 um element keeps fine swarf out of the workholding valves, and the lower pressure range prevents over-clamping thin-walled components.
Laboratory Air Supply
Supply a lab bench with clean, oil-misted air for a small diaphragm pump or an air bearing. The 0.15-0.4 MPa band gives fine control for sensitive experiments, and the 185 cc oil bowl keeps the lubricator running between checks.
Low-Force Packaging Gripper
Run a packaging gripper that handles soft goods or filled pouches without crushing them. The lower pressure range protects the product, while the 100 cc condensate bowl handles moisture from a busy line with fewer drain checks.
Is the Airtac GAFC Air Service Unit GAFC40015LNW the Right Air-Prep Unit?
Choose the GAFC40015LNW when your line needs a 1/2in port and a regulated ceiling of 0.4 MPa (20-58 psi) - the lower-pressure type suits gentle actuators or precision blow-off work. The PC bowl is the standard build, and the 5 um element filters finer than the 40 um default, though it will need more frequent service. The semi-auto drain dumps condensate when pressure drops, with a manual override for on-demand use.
The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, so plan the inlet pressure carefully to stay within the regulated band. Spares are the GAFR400-15 filter-regulator and GAL400-15 lubricator, both orderable separately.
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 GAFC40015LNW FAQ
The GAFC40015LNW operates from 0.15 to 0.4 MPa (20-58 psi) with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. It works in -5 to 70 C temperatures and needs ISO VG 32 lubricant. The drain bowl holds 100 cc, the oil bowl 185 cc, and the unit weighs 1810 g.
The N in the code means no gauge is supplied. The GAFC400 body has a 1/4in gauge connection, so you can add a circular gauge there to read the set pressure. Without one, you cannot verify the outlet pressure visually, so plan to fit a gauge if operators need to check the setting.
