Airtac GAFR Adjustable Filter Regulator GAFR300C10SWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR300C10SWK 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 GAFR300C10SWK
The GAFR300C10SWK is a filter and regulator combined into one body, eliminating the need for separate GAF and GAR units. It spins incoming air to separate liquid water and trap solid particles, then delivers a steady outlet pressure via a balanced, self-locking regulator. This model has a 3/8" port, a 0.15-0.9 MPa (20-130 psi) working range, and a 5 um element for finer filtration.
The metal bowl (C) holds 60 cc of condensate, and the unit weighs 500 g. It includes both semi-auto and manual drains, a circular gauge with MPa/psi scale, and the mounting bracket. The reverse-flow (reflux) valve is fitted as an ordering difference, and the unit is rated for -5 to 70 C without freezing.

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 GAFR300C10SWK Is Used
Precision valve control
The 5 um element protects sensitive pneumatic valves from fine particles, while the balanced regulator holds a stable setpoint for consistent actuation.
Machine tool circuits
A 3/8" port and 500 g mass suit a single machine station or a small jig, where the metal bowl resists rough handling on the shop floor.
Assembly line air prep
The semi-auto and manual drains let operators purge condensate on schedule, keeping a 60 cc bowl from overflowing during a shift.
Is the Airtac GAFR Adjustable Filter Regulator GAFR300C10SWK the Right Air-Prep Unit?
Choose the GAFR300 body for a 3/8" port and a 60 cc drain bowl, sitting between the smaller GAFR200 (25 cc) and larger GAFR400 (100 cc). The metal bowl is a build choice; the common 1.0 MPa max and -5 to 70 C range apply to all bowl materials, so confirm compatibility for aggressive surroundings. This model has the 5 um element for trapping finer particles, the standard pressure type, and both semi-auto and manual drains for flexible servicing. The bracket is included, the gauge is fitted with a PT thread and MPa/psi scale, and the reflux valve is present. For lines needing oil downstream, order the matching GAFC300-10 combination instead. 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 60 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 500 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 GAFC300-10 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR300C10SWK FAQ
Working pressure is 0.15-0.9 MPa (20-130 psi), max pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), and temperature range is -5 to 70 C. The drain bowl holds 60 cc and the unit weighs 500 g.
The K code indicates the reverse-flow (reflux) valve is fitted. It is an ordering difference only; the catalogue defers its function to a separate page not included in our data.
