About the Airtac GAFC Air Service Unit GAFC40015SN
The GAFC40015SN is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator on a shared T-bracket. Air enters the 1/2" port, gets filtered to 40 um and regulated to 0.15-0.9 MPa (20-130 psi), then the lubricator meters ISO VG 32 oil mist into the flow last, so oil never travels back through the regulator seat. This 1810 g unit suits a mid-size machine header or a multi-station line where a 1/2" feed is the main air supply.
No gauge is supplied with this model, so the set pressure cannot be read without adding one; the 1/4" gauge connection is ready for a field-installed gauge. The 100 cc condensate bowl and 185 cc oil bowl set the service rhythm, and the semi-auto drain dumps condensate each time pressure drops while the manual drain gives on-demand control. The PC bowl is the standard build choice, and the catalogue's 1.0 MPa max pressure and -5 to 70 C range apply unchanged to it.

Constituent units, orderable separately as spares: GAFR400-15 filter & regulator, GAL400-15 lubricator — both share this body and port. A GAFC has two units, not three: the filter and the regulator are one body.

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 GAFC40015SN Is Used
CNC spindle lubrication
Feed a 1/2" line to a CNC spindle air curtain, where the regulated 0.15-0.9 MPa range keeps the spindle seal pressure stable and the lubricator oils the air tooling downstream.
Assembly station headers
Supply a multi-operator assembly station with filtered, regulated air for pneumatic screwdrivers and push cylinders, using the 100 cc condensate bowl to handle moisture from a busy compressor.
Packaging line actuators
Run a packaging conveyor's diverters and stops from one 1/2" point, where the 185 cc oil bowl keeps lubricated air flowing to multiple actuators between service checks.
Is the Airtac GAFC Air Service Unit GAFC40015SN the Right Air-Prep Unit?
Choose the GAFC400 body for a 1/2" port with a 6000 L/min flow curve plotted at 0.7 MPa inlet, stepping up from the GAFC300's 3500 L/min envelope when a line needs more air. The blank bowl code specifies a PC bowl, and the semi-auto plus manual drain pair handles condensate without power; the 40 um element is the standard grade, while the W option swaps in a 5 um element for finer filtration at the cost of more frequent element service. The N after the port means no gauge is fitted, so plan to add one on the 1/4" connection if operators need to read the setpoint, and the PT thread carries an MPa/psi gauge scale if a gauge is added. Spare parts are orderable separately as the GAFR400-15 filter & regulator and the GAL400-15 lubricator, so a worn element or damaged bowl does not force a full replacement. Since the lubricator adds oil mist, choose a plain GAFR400-15 instead if the downstream line must stay oil-free. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan a supply near the maximum if you need the full 0.9 MPa output.
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 GAFC40015SN FAQ
This F.R.L. combination operates on air with a standard pressure range of 0.15-0.9 MPa (20-130 psi), a max pressure of 1.0 MPa (145 psi), and a proof pressure of 1.5 MPa (215 psi). It works in -5 to 70 C temperatures, holds a 100 cc condensate bowl and a 185 cc oil bowl, and weighs 1810 g. Use ISO VG 32 or equivalent oil in the lubricator.
The N in the code after the port means no gauge is supplied, so you cannot read the set pressure directly on the unit. The GAFC400 body has a 1/4" gauge connection, so you can add a compatible gauge later if operators need to verify the regulated output.
