Airtac GAFR Adjustable Filter Regulator GAFR40010SNW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40010SNW 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 GAFR40010SNW
The GAFR40010SNW is a filter & regulator that combines both functions in one body, saving rail space and reducing potential leak points compared to separate units. It handles a 3/8in port with a 100 cc condensate bowl, weighing 880 g, and uses a 5 um element for finer filtration.
This standard type operates from 0.15-0.9 MPa (20-130 psi) and includes both semi-auto and manual drains. The diversion structure spins incoming air to separate liquid water and solid particles into the bowl, while the balanced regulator maintains a steady outlet pressure as supply varies.

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 GAFR40010SNW Is Used
Precision valve control
The 5 um element protects sensitive pneumatic valves and instruments from fine particulate, making this unit suitable for precision manufacturing stations where consistent air quality matters.
Medium-flow machine lines
With a 3/8in port and 100 cc bowl, this filter-regulator feeds medium-duty actuators and machine headers, providing clean, regulated air to multiple points from a single compact body.
Panel-mounted installations
The included mounting bracket allows secure panel mounting, and the 880 g weight confirms this unit needs proper support rather than being suspended from tubing alone.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40010SNW the Right Air-Prep Unit?
Choose the GAFR400 body for medium-flow lines; its 7000 L/min plotted flow envelope at 0.7 MPa inlet sits between the GAFR300 (3500 L/min) and GAFR500 (8000 L/min). The PC bowl suits general shop air, while the included bracket simplifies mounting. The 5 um element traps finer particles than the standard 40 um, ideal for precision valves, though it will need more frequent service. This unit ships with both semi-auto and manual drains, and the PT thread provides an MPa/psi gauge scale. If downstream lubrication is needed, order the matching GAFC400-10 combination instead. With a 1.0 MPa max supply, you have about 0.1 MPa 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 GAFR40010SNW FAQ
This filter & regulator has a 3/8in port, operates from 0.15-0.9 MPa (20-130 psi), with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Temperature range is -5 to 70 C. The drain bowl holds 100 cc and the unit weighs 880 g. It uses a 5 um element and has both semi-auto and manual drains.
The 'N' in the code means no gauge is supplied, so the set pressure cannot be read without adding one. The gauge connection on the GAFR400 body is 1/4in, so a gauge with that thread can be fitted later if needed.
