Airtac GAFR Adjustable Filter Regulator GAFR40010ASWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40010ASWK 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 GAFR40010ASWK
The GAFR40010ASWK is a filter and regulator combined into a single body, eliminating the need for separate GAF and GAR units. It delivers 3/8" porting, a 0.15-0.9 MPa (20-130 psi) standard pressure range, and a 5 um element for finer filtration.
This model includes a circular gauge with MPa/psi scale, an automatic drain, and a reverse-flow valve. The 100 cc condensate bowl and 880 g weight define its size class, requiring a proper panel or frame mount rather than tubing support.

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 GAFC400-10 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 GAFR40010ASWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves that require clean, 5 um filtered air and stable pressure regulation within a compact footprint.
Machine tool circuits
Supply a machining center's clamping and tool-change circuits with regulated air, where the automatic drain reduces maintenance on wet shop lines.
Test bench setup
Provide clean, regulated air to a laboratory test bench with sensitive instruments, using the 5 um element and gauge for accurate setpoint verification.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40010ASWK the Right Air-Prep Unit?
Choose the GAFR400 body for 3/8" or 1/2" ports, with a 7000 L/min flow curve at 0.7 MPa inlet. The PC bowl suits standard shop air; select metal or nylon only if your environment demands it. The automatic drain (A) handles wet or unattended lines, while the 5 um element (W) traps finer particles for sensitive equipment. This unit includes the mounting bracket, a fitted gauge, and the reverse-flow valve (K). If oil is needed downstream, order the matching GAFC400-10 combination instead. 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 GAFR40010ASWK FAQ
Pressure range is 0.15-0.9 MPa (20-130 psi), max pressure 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi), temperature range -5 to 70 C. The drain bowl holds 100 cc and the unit weighs 880 g.
The K code indicates the reverse-flow (reflux) valve is fitted as an ordering difference. Its detailed function is covered in the catalogue; for this listing, it is a specified option on the GAFR40010ASWK.
