Airtac GAFR Adjustable Filter Regulator GAFR400C10SW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR400C10SW 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 GAFR400C10SW
The GAFR400C10SW is a filter and regulator combined into a single metal-bodied unit, saving rail space compared to separate filter and regulator components. It handles 3/8in ports, delivers 0.15-0.9 MPa (20-130 psi), and uses a 5 um element to trap fine particles.
Air is spun through a diversion structure that separates liquid water and solid debris into the 100 cc condensate bowl, while the balanced regulator holds the set outlet pressure steady as supply varies. This 880 g unit includes a circular gauge with MPa/psi scale and a mounting bracket, with no lubricator fitted.

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 GAFR400C10SW Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a machining center, where the 5 um element protects fine internal passages from particle wear.
Assembly line actuators
Supply a row of assembly fixtures with stable 0.15-0.9 MPa pressure, using the 100 cc bowl to collect condensate between shifts.
Test rig air supply
Provide clean, regulated air to a laboratory test bench where the metal bowl resists knocks and the gauge lets operators verify setpoints.
Is the Airtac GAFR Adjustable Filter Regulator GAFR400C10SW the Right Air-Prep Unit?
Choose the GAFR400 body for mid-size machine circuits; its 7000 L/min flow envelope at 0.7 MPa inlet inlet sits between the GAFR300's 3500 L/min and the GAFR500's 8000 L/min. The metal bowl suits demanding shop environments, and the 5 um element filters finer than the standard 40 um for sensitive valves. This model has the semi-auto plus manual drain, a fitted gauge, and the mounting bracket included. The PT thread gives an MPa/psi gauge scale, and no reflux valve is attached. If oil is needed downstream, order the GAFC400-10 combination instead. With a 1.0 MPa max supply, the 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 GAFR400C10SW FAQ
Working pressure is 0.15-0.9 MPa (20-130 psi), max 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, the unit weighs 880 g, and the flow curve is plotted to 7000 L/min at 0.7 MPa inlet.
The C code specifies a metal bowl instead of the standard PC or optional nylon. Metal is a build choice for environments where a transparent bowl is not required; the pressure and temperature ratings remain the same at 1.0 MPa max and -5 to 70 C. Confirm compatibility with aggressive media before use.
