About the Airtac GAFC Air Service Unit GAFC40015ALNW
This AirTAC GAFC40015ALNW is an F.R.L. combination built from two units on a single T-shape bracket: a GA-series filter-regulator (the filter and regulator share one body) followed by a GA-series lubricator. With a 1/2in port and a 1810 g mass, it sits in the mid-size class of the GAFC range, suited to a machine header feeding several actuators rather than a single small cylinder.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), and the 5 um element traps finer particles than the standard 40 um grade for sensitive valves. The automatic drain clears condensate from the 100 cc bowl without operator attention, while the 185 cc oil bowl carries ISO VG 32 lubricant. No gauge is supplied, so the set pressure cannot be read without adding one to the 1/4in gauge connection.

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 GAFC40015ALNW Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a packaging machine where the 5 um element protects fine internal passages and the lower pressure range prevents overdriving sensitive actuators.
Machine tool lubrication
Supply a metered oil mist to slide ways and spindles on a CNC lathe, where the 185 cc oil bowl supports extended runs between refills and the automatic drain keeps the condensate bowl clear.
Assembly line air prep
Prepare air for a multi-station assembly conveyor with 1/2in drop lines, giving each station filtered, regulated, and lubricated air from one central unit with a 1810 g body that mounts securely on the frame.
Is the Airtac GAFC Air Service Unit GAFC40015ALNW the Right Air-Prep Unit?
Choose the GAFC40015ALNW when your line needs 1/2in ports, a 0.15-0.4 MPa regulated band, and a 5 um element. The PC bowl is the standard build; the catalogue gives no material-specific data, so confirm it suits your environment. The automatic drain handles wet or unattended lines, and the PT thread carries an MPa/psi gauge scale if you fit a gauge later. For a lower flow demand, the GAFC300 with its 3500 L/min envelope at 0.7 MPa inlet is a smaller step down; for higher flow, the GAFC500 offers a 7000 L/min envelope at 0.7 MPa inlet. Spare parts are the GAFR400-15 filter-regulator and the GAL400-15 lubricator, both orderable separately. If your line must stay oil-free, omit the lubricator and choose a plain GAFR filter-regulator instead. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, so plan your inlet pressure with that margin in mind.
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 GAFC40015ALNW FAQ
The GAFC40015ALNW operates from 0.15 to 0.4 MPa (20-58 psi) with a max pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It has a 5 um filter element, a 100 cc condensate bowl, and a 185 cc oil bowl. The recommended lubricant is ISO VG 32, the weight is 1810 g, and the temperature range is -5 to 70 C. It uses a 1/2in PT thread and has no gauge fitted.
The 'N' in the code after the port means no gauge is supplied with the unit. The GAFC400 body has a 1/4in gauge connection, so you can add a compatible pressure gauge later if you need to read the set pressure. The PT thread on this model would use an MPa/psi scale if a gauge is fitted.
