Airtac GAFR Adjustable Filter Regulator GAFR40010S
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40010S 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 40 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 GAFR40010S
The GAFR40010S is a filter and regulator combined into a single body, removing the need for separate components on your air line. It spins incoming air to separate liquid water and trap solid particles, then delivers a steady outlet pressure through its balanced regulator. This model uses a 3/8in port, a 40 um element, and a working range of 0.15-0.9 MPa (20-130 psi).
With a 100 cc condensate bowl and an 880 g mass, this unit suits medium-duty machine circuits where space is limited. The pressed-in self-locking knob holds the set pressure against vibration, so the outlet stays stable without frequent readjustment. No lubricator is built in; this is strictly filtration and pressure control in one housing.

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 GAFR40010S Is Used
Machine tool circuits
Feed a single machining station or a small indexing table where stable pressure is critical for consistent clamping force and actuator speed.
Assembly line stations
Supply filtered air to pneumatic screwdrivers or presses at a dedicated workbench, with the 100 cc bowl reducing drain frequency during a full shift.
Test rigs and benches
Provide clean, regulated air to prototype fixtures or calibration equipment where the 40 um element protects sensitive valves from particulate damage.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40010S the Right Air-Prep Unit?
Choose the GAFR40010S when your line needs a 3/8in port with a 100 cc drain bowl, stepping up from the GAFR300's 60 cc bowl for longer intervals between draining. The PC bowl suits general shop air, while the metal (C) or nylon (N) bowl options are available for different build preferences. This unit ships with both semi-auto and manual drains, the mounting bracket, and a circular gauge with MPa/psi scale; the standard 40 um element handles typical workshop filtration. If you need finer filtration, select the W option for a 5 um element, or add the K code for a reverse-flow valve. For lines requiring oil downstream, order the matching GAFC400-10 combination instead, as this unit does not lubricate. Max supply 1.0 MPa 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 GAFR40010S FAQ
Working pressure range is 0.15-0.9 MPa (20-130 psi), with a maximum supply of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Temperature range is -5 to 70 C. The condensate bowl holds 100 cc and the unit weighs 880 g. It uses a 40 um element and has a 3/8in port.
The GAFR40010S combines both functions in one body, so you get filtration and pressure regulation without installing two separate units. A GAF only filters, and a GAR only regulates. This integrated design means fewer pipe joints and less space required on your rail.
