Airtac GAFR Adjustable Filter Regulator GAFR40015LN
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40015LN is a genuine two-in-one filter & regulator — a diversion-type water/particulate filter and a balanced pressure regulator built into ONE body. It has 1/2" ports, a 40 µm filter element and regulates 0.15 - 0.4 MPa (20 - 58 psi). It has no lubricator, so it adds no oil to the airflow.

About the Airtac GAFR Adjustable Filter Regulator GAFR40015LN
The GAFR40015LN is a filter and pressure regulator combined in a single body, removing the need for separate units on your line. It handles a 1/2in port with a lower pressure range of 0.15-0.4 MPa (20-58 psi), using a 40 um element to trap solids and water.
This 880 g unit includes a 100 cc condensate bowl and a semi-auto plus manual drain. The balanced regulator holds your set pressure steady as supply varies, and the pressed-in self-locking knob resists drift from vibration.

Specifications follow the official AirTAC GAFR catalogue (pages 235-236). Air must not freeze in the unit. No gauge is supplied with this model — the gauge connection on a GAFR400 is 1/4" if you add one. This unit filters and regulates only; it does not add lubrication.

The filter and the regulator are ONE body here — there is no separate GAF filter or GAR regulator part to assemble. Need lubrication downstream too? Add a lubricator by ordering the matching GAFC400-15 F.R.L. combination instead.

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 GAFR Adjustable Filter Regulator GAFR40015LN Is Used
Precision pressure setting
Set a stable 0.3 MPa for a sensitive pneumatic actuator on a small assembly fixture, with the self-locking knob holding the value despite nearby machine vibration.
Compact machine build
Mount this 880 g unit on a panel or frame to feed a single 1/2in line, saving rail space compared to separate filter and regulator bodies.
Low-pressure test bench
Use the 0.15-0.4 MPa range to supply a gentle air signal for a leak test or low-force checking station, with the 100 cc bowl handling normal condensate.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40015LN the Right Air-Prep Unit?
Choose this GAFR400 for 1/2in piping where you need a compact filter-regulator combo. The lower pressure type (L) tops out at 0.4 MPa, so confirm your application never requires more than that. The PC bowl is standard, and the mounting bracket is included. No gauge is fitted, but the 1/4in gauge connection is ready for one. The 40 um element suits general shop air; upgrade to a 5 um element for finer filtration. If your line needs lubrication downstream, order the matching GAFC400-15 combination instead. With a 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
- ✓ Bracket kept or removed (J); add a lubricator = GAFC
Installation & Maintenance Notes
- check Install with the airflow arrow: IN to OUT, gauge/knob accessible.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Set pressure with the pressed-in self-locking knob; pull to adjust, press to lock.
- check Drain condensate before the 100 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 880 g unit on its bracket, not on the tubing.
This is a filter and regulator only — it delivers filtered, pressure-set air with no added oil. If a downstream tool needs lubrication, add a separate lubricator or order the GAFC400-15 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR40015LN FAQ
The GAFR40015LN is a filter & regulator with a 1/2in port, working pressure 0.15-0.4 MPa (20-58 psi), max pressure 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi), temperature range -5 to 70 C, 40 um element, 100 cc drain bowl, and weight 880 g. It has a semi-auto plus manual drain and no gauge fitted.
The L code means the regulator is set for 0.15-0.4 MPa, ideal for low-force applications that never need higher pressure. The N code after the port means no gauge is supplied; the 1/4in gauge connection is there if you add one later. This keeps the unit compact and cost-effective for dedicated low-pressure lines.
