Airtac GAFR Adjustable Filter Regulator GAFR300C15AS
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR300C15AS 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 1/2" 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 GAFR300C15AS
The GAFR300C15AS is a filter and regulator combined into a single body, eliminating the need for separate components. It spins incoming air to separate liquid water and trap solid particles, then delivers a steady outlet pressure via its balanced regulator. This 1/2in model has a 60 cc metal condensate bowl and weighs 500 g, making it a compact choice for medium-flow lines.
This unit operates from 0.15 to 0.9 MPa (20-130 psi) and comes with a 40 um element. The metal bowl suits demanding environments, while the automatic drain clears condensate without manual intervention. The circular gauge with MPa/psi scale is fitted, and the mounting bracket is included for secure installation.

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 GAFC300-15 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 GAFR300C15AS Is Used
Machine tool circuits
Feed a single machining center's pneumatic controls with clean, regulated air. The 1/2in port and 60 cc bowl handle typical solenoid valve banks and actuation cylinders.
Assembly line stations
Mount at a workbench or panel to supply filtered air to pneumatic hand tools and fixtures. The automatic drain keeps the station running without daily maintenance.
Test rigs and benches
Provide stable pressure to test fixtures and gauges. The balanced regulator holds the setpoint as shop supply fluctuates, and the metal bowl resists knocks in a busy lab.
Is the Airtac GAFR Adjustable Filter Regulator GAFR300C15AS the Right Air-Prep Unit?
Choose the GAFR300 body for 1/2in ports when you need a 60 cc drain bowl and a flow envelope plotted to 3500 L/min at 0.7 MPa inlet. The metal bowl (C) is a build choice for tougher surroundings; confirm compatibility for aggressive media. The automatic drain (A) handles wet lines or unattended operation, while the standard type (S) covers 0.15-0.9 MPa. The included bracket and gauge are standard; omit them with J and N if not needed. The 40 um element suits general shop air; upgrade to 5 um (W) for finer filtration. PT threads give an MPa/psi gauge scale. If oil is needed downstream, order the matching GAFC300-15 combination. 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 (1/2" 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 GAFC300-15 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR300C15AS FAQ
Working pressure is 0.15-0.9 MPa (20-130 psi), with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. Temperature range is -5 to 70 C. The drain bowl holds 60 cc and the unit weighs 500 g. It has a 40 um element and a 1/2in port.
The automatic drain (A) expels condensate from the 60 cc bowl without manual action, ideal for wet supply lines or unattended operation. The metal bowl (C) is fitted, and there is no lubricator - this is a filter and regulator only.
