Airtac GAFR Adjustable Filter Regulator GAFR300C08SW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR300C08SW 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 1/4" 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 GAFR300C08SW
The GAFR300C08SW is a filter and regulator combined into a single body, so incoming air is cleaned and then set to a steady outlet pressure without needing separate units. This model uses a 1/4in port, a metal bowl, and a 5 um element to trap fine particles for sensitive equipment.
Its working 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). The metal bowl holds 60 cc of condensate, and the whole unit weighs 500 g, making it a compact choice for a single actuator or small jig.

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 GAFR300C08SW Is Used
Precision valve control
Feed a single precision pneumatic valve or small actuator with clean, regulated air at a stable pressure, using the 5 um element to protect sensitive internal parts.
Bench test setup
Use on a test bench or prototyping rig where a compact filter regulator with a metal bowl is needed to condition air for a single cylinder or air tool.
Light assembly line
Install on a light assembly station to supply a consistent 0.15-0.9 MPa to a pick-and-place unit or small clamping fixture, with the included bracket for panel mounting.
Is the Airtac GAFR Adjustable Filter Regulator GAFR300C08SW the Right Air-Prep Unit?
Choose the GAFR300 body for 1/4in or 3/8in ports; if you need more flow, step up to the GAFR400 with its 7000 L/min envelope at 0.7 MPa inlet, or drop to the GAFR200 for lighter duty. The metal bowl is a build choice with the same 1.0 MPa max and -5 to 70 C rating as PC or nylon, so confirm compatibility for aggressive surroundings. This unit ships with both semi-auto and manual drains, the standard pressure type, a mounting bracket, and a circular gauge with MPa/psi scale; the 5 um element is for finer filtration than the standard 40 um. If the line needs oil downstream, order the matching GAFC300-08 combination instead, as this filter regulator does not lubricate. 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 (1/4" 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 GAFC300-08 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR300C08SW FAQ
The GAFR300C08SW is a filter and regulator with a 1/4in port, working pressure 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, 60 cc metal drain bowl, and 500 g weight. It has a 5 um element, semi-auto plus manual drain, and a fitted gauge.
The C code indicates a metal bowl instead of the standard PC or optional nylon. It holds the same 60 cc of condensate and is rated to the same 1.0 MPa max and -5 to 70 C, so the choice is about build and environment compatibility. Confirm suitability for your specific surroundings, as no chemical or impact data is published.
