Airtac GAFR Adjustable Filter Regulator GAFR40015SN
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40015SN 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 - 0.9 MPa (20 - 130 psi). It has no lubricator, so it adds no oil to the airflow.

About the Airtac GAFR Adjustable Filter Regulator GAFR40015SN
The GAFR40015SN is a filter and regulator combined into a single body, handling both air preparation tasks without needing separate units. It serves 1/2in lines with a 40 um element, a 100 cc condensate bowl, and a working range of 0.15-0.9 MPa (20-130 psi).
This 880 g unit integrates a diversion structure that spins incoming air to separate liquid water and solid particles into the bowl. The balanced regulator mechanism holds the set outlet pressure steady as supply pressure 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 GAFR40015SN Is Used
Machine tool circuits
Feed a precision drilling or tapping fixture where stable 0.15-0.9 MPa pressure protects tool life and part finish, with the 40 um element guarding sensitive valves.
Assembly station air
Supply a multi-operator assembly bench with filtered, regulated air for pneumatic screwdrivers and push-in fittings, relying on the 100 cc bowl to handle condensate across shifts.
Test rig supply
Provide clean, regulated air to a leak-test or function-test rig where consistent pressure is critical, and the 1/2in port matches common manifold headers.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40015SN the Right Air-Prep Unit?
Choose the GAFR400 for 3/8in or 1/2in ports where the 100 cc drain bowl and 7000 L/min flow envelope (plotted at 0.7 MPa inlet) suit medium machine sections. This model ships with the mounting bracket included, a PC bowl, a 40 um element, and both semi-auto and manual drains fitted. The PT thread option pairs with a gauge scale in MPa/psi, though this version has no gauge supplied; the 1/4in gauge connection is ready for a field-installed unit. If downstream lubrication is ever required, the matching GAFC400-15 combination adds a lubricator while keeping the same body and port. Note that 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan inlet pressure near the maximum for full regulated 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
- ✓ 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 GAFR40015SN FAQ
The GAFR40015SN is a filter & regulator with a 1/2in port, 40 um element, and a pressure range of 0.15-0.9 MPa (20-130 psi). Maximum pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), and temperature range is -5 to 70 C. The drain bowl holds 100 cc and the unit weighs 880 g.
The N code after the port means no gauge is supplied. The GAFR400 has a 1/4in gauge connection, so you can add a compatible AirTAC gauge later if you need to read the set pressure locally. Without one, the outlet pressure cannot be monitored directly on the unit.
