Airtac GAFR Adjustable Filter Regulator GAFR400C10ASJNW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR400C10ASJNW 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 3/8" ports, a 5 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 GAFR400C10ASJNW
The GAFR400C10ASJNW is a filter and pressure regulator combined in a single metal-bodied unit, eliminating the need for separate GAF and GAR components. It delivers clean, regulated air at 3/8" ports with a working range of 0.15-0.9 MPa (20-130 psi) and a 5 um filtering element.
The metal bowl holds 100 cc of condensate, and the automatic drain clears it without manual intervention. Weighing 880 g, this unit is sized for machine headers or multi-station lines where a compact footprint and reliable pressure stability matter.

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.

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 GAFR400C10ASJNW Is Used
Precision Valve Control
Feed a bank of precision pneumatic valves on an assembly station, where the 5 um element protects fine internal passages from particle wear.
Machine Header Supply
Mount on a machine frame to supply a 3/8" header for multiple actuators, using the automatic drain to handle condensate without daily checks.
Test Rig Air Supply
Provide stable, filtered air to a test fixture with sensitive instrumentation, relying on the balanced regulator to hold set pressure as shop supply fluctuates.
Is the Airtac GAFR Adjustable Filter Regulator GAFR400C10ASJNW the Right Air-Prep Unit?
Choose the GAFR400 body for 3/8" or 1/2" ports; it offers a 7000 L/min flow envelope at 0.7 MPa inlet, stepping up from the GAFR300's 3500 L/min. The metal bowl (C) suits demanding environments, while the automatic drain (A) handles wet or unattended lines. This model omits the bracket (J) for panel mounting and has no gauge (N), so plan to add one via the 1/4" connection. The 5 um element (W) traps finer particles than the standard 40 um, and PT threads with MPa/psi scale are fitted. If downstream lubrication is needed, order the matching GAFC400-10 combination. Note that 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range.
Quick checklist
- ✓ Body size for your peak flow (3/8" 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 GAFC400-10 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR400C10ASJNW FAQ
Working pressure is 0.15-0.9 MPa (20-130 psi), with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. Temperature range is -5 to 70 C. The metal drain bowl holds 100 cc and the unit weighs 880 g.
The 'N' after the port code means no gauge is supplied, leaving a 1/4" connection for adding one. The 'J' code omits the mounting bracket, which suits panel-mount installations or existing frames. Both options reduce cost when standard accessories are not needed.
