About the Airtac GAFC Air Service Unit GAFC300C15LWK
This GAFC300C15LWK is a two-piece F.R.L. combination: a filter-regulator body handles filtration and pressure setting, then a separate lubricator adds a metered oil mist downstream. The 1/2in port and 1020 g mass place it in the mid-size class, suited for feeding a single machine station or a small multi-actuator circuit.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), with a 5 um element trapping fine particles for sensitive valves. The metal bowl and semi-auto plus manual drain handle condensate, while the circular gauge reads in MPa and psi. A reverse-flow valve is fitted, and the two units are separately orderable as GAFR300-15 and GAL300-15.

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 GAFC300C15LWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a packaging machine that requires stable, lower-pressure actuation below 0.4 MPa, with fine 5 um filtration to protect sensitive spools.
Conveyor tensioning
Maintain a gentle, regulated air supply for conveyor belt tensioning rollers on an assembly line, where the lower pressure range prevents over-tensioning and the metal bowl resists shop-floor impacts.
Test bench air supply
Supply a laboratory test bench with clean, regulated air at a fixed low pressure for calibration fixtures, using the 5 um element to keep instrument orifices clear and the gauge for precise setpoint verification.
Is the Airtac GAFC Air Service Unit GAFC300C15LWK the Right Air-Prep Unit?
Choose this model when your circuit needs a regulated band capped at 0.4 MPa, not the standard 0.9 MPa ceiling. The 5 um element suits precision pneumatic controls, but expect more frequent element service than a 40 um unit. The metal bowl is a build choice; confirm it fits your environment since the catalogue lists no material-specific ratings. The semi-auto drain dumps condensate when pressure drops, with a manual backup for on-demand purging. The fitted gauge shows MPa and psi on a PT thread. For oil-free lines, omit the lubricator and select a plain GAFR300-15 instead. The reverse-flow valve is included per the K code. With 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of the regulated range.
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 60 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1020 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 GAFR300-15 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC300C15LWK FAQ
This F.R.L. combination operates on air from 0.15 to 0.4 MPa (20-58 psi), with a maximum supply pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It works in temperatures from -5 to 70 C and uses ISO VG 32 oil. The drain bowl holds 60 cc and the oil bowl 98 cc, with a total weight of 1020 g.
The L code sets a regulated ceiling of 0.4 MPa instead of the standard 0.9 MPa, which suits delicate actuators or processes that must never see higher pressure. With a 1.0 MPa max supply, you have 0.6 MPa of headroom above the top setting, so the regulator can maintain its setpoint without being starved. If your machine may ever need more than 0.4 MPa, this is the wrong part.
