Airtac GAFR Adjustable Filter Regulator GAFR400C10ASW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR400C10ASW 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 GAFR400C10ASW
The GAFR400C10ASW is a filter and regulator combined into a single body, handling both air cleaning and pressure stabilization in one compact unit. It uses a diversion structure to spin incoming air, separating liquid water and solid particles into the 100 cc metal condensate bowl, while the balanced regulator maintains a steady outlet pressure as supply varies.
This model has a 3/8" port, a standard pressure range of 0.15-0.9 MPa (20-130 psi), and a 5 um filter element for trapping finer particles. The pressed-in self-locking knob resists drift from vibration, and the included circular gauge shows the set pressure on an MPa/psi scale.

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 GAFR400C10ASW Is Used
Precision valve control
Feed a bank of precision pneumatic valves that demand clean, stable air at a consistent pressure. The 5 um element traps fine particles that could clog small orifices, while the balanced regulator holds the setpoint steady as line pressure fluctuates.
Machine tool air supply
Supply filtered air to a CNC machine's clamping fixtures or tool changers. The 100 cc metal bowl handles condensate from a busy production line, and the automatic drain clears it without stopping the machine for manual maintenance.
Test bench instrumentation
Provide clean, regulated air to a test bench with sensitive gauges and flow meters. The 5 um element and stable regulation protect instruments from contamination and pressure swings, while the included gauge lets operators verify settings at a glance.
Is the Airtac GAFR Adjustable Filter Regulator GAFR400C10ASW the Right Air-Prep Unit?
Choose the GAFR400 body when you need a 3/8" port with a 100 cc drain bowl and a flow curve plotted to 7000 L/min at 0.7 MPa inlet; it sits between the GAFR300 (60 cc bowl, 3500 L/min envelope) and the GAFR500 (108 cc bowl, 8000 L/min envelope). The metal bowl suits demanding environments, while the automatic drain (A) handles unattended operation or wet lines without manual intervention. The 5 um element (W) captures finer particles than the standard 40 um grade, though it will need more frequent servicing. The mounting bracket is included, and the PT thread means the gauge reads in MPa/psi. If your line needs lubrication downstream, order the matching GAFC400-10 combination instead, since this unit does not add oil. Note that the 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan for a supply near 1.0 MPa if you need maximum outlet pressure.
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 GAFR400C10ASW FAQ
The GAFR400C10ASW is a filter & regulator with a 3/8" port, working pressure range of 0.15-0.9 MPa (20-130 psi), maximum pressure of 1.0 MPa (145 psi), and proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C and must not freeze. The drain bowl holds 100 cc and the unit weighs 880 g. It has a 5 um filter element and an automatic drain.
The C code specifies a metal condensate bowl instead of the standard PC plastic bowl. The pressure and temperature ratings are identical to the PC version (1.0 MPa max, -5 to 70 C), so the metal bowl is a build and environment choice. For aggressive surroundings, confirm compatibility with your specific conditions before ordering.
