Airtac GAFR Adjustable Filter Regulator GAFR400C10ASNWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR400C10ASNWK 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 GAFR400C10ASNWK
The GAFR400C10ASNWK is a filter and regulator combined in a single metal-bodied unit, removing water and solid particles before stabilizing outlet pressure. This 3/8in model operates from 0.15 to 0.9 MPa (20-130 psi) and comes with a 5 um element for finer filtration.
Its 100 cc condensate bowl and automatic drain handle moisture in unattended lines, while the 880 g mass signals a unit that needs proper mounting. The balanced regulator holds set pressure as supply varies, and the pressed-in 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.

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 GAFR400C10ASNWK Is Used
CNC coolant lines
Feed a 5 um-filtered air supply to precision valves on a CNC machine, with the automatic drain clearing condensate during long automated runs.
Assembly station headers
Mount this 3/8in unit on a station header feeding multiple pneumatic tools, where the metal bowl resists impacts from nearby handling equipment.
Test bench air supply
Provide stable regulated pressure to a laboratory test bench, where the 5 um element protects sensitive instruments and the included bracket simplifies panel mounting.
Is the Airtac GAFR Adjustable Filter Regulator GAFR400C10ASNWK the Right Air-Prep Unit?
Choose the GAFR400 body for medium-flow lines; its 7000 L/min plotted envelope at 0.7 MPa inlet sits between the GAFR300's 3500 L/min and the GAFR500's 8000 L/min. The metal bowl suits demanding environments, and the 5 um element traps finer particles than the standard 40 um for precision applications. This model includes the mounting bracket, uses an automatic drain for wet lines, and omits the gauge - the 1/4in gauge connection is ready for a field-installed unit. The PT thread carries an MPa/psi scale, and the reverse-flow valve is fitted as an ordering option. If oil is needed downstream, order the matching GAFC400-10 combination instead. With a 1.0 MPa max supply, you get about 0.1 MPa of headroom above the 0.9 MPa top of the regulated 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 GAFR400C10ASNWK FAQ
Working pressure is 0.15-0.9 MPa (20-130 psi), with 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. Temperature range is -5 to 70 C. The drain bowl holds 100 cc and the unit weighs 880 g. It has a 3/8in port, 5 um element, and automatic drain.
The N code means no gauge is supplied, saving cost when you have a panel-mounted gauge or want to install your own. The GAFR400 body has a 1/4in gauge connection, so any standard 1/4in gauge can be fitted later if needed.
