Airtac GAFR Adjustable Filter Regulator GAFR300C15ASJN
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR300C15ASJN 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 GAFR300C15ASJN
The GAFR300C15ASJN is a filter and regulator combined into one body, so it cleans incoming air and sets a steady outlet pressure without needing separate parts. This unit has a 1/2in port, works from 0.15 to 0.9 MPa (20-130 psi), and uses a 40 um element to trap particles.
The metal bowl holds 60 cc of condensate, and the automatic drain clears it without manual attention. Weighing 500 g, this size class suits panel mounting rather than tubing support. The balanced regulator keeps the set pressure stable as supply varies, and the pressed-in knob resists drift from vibration.

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 GAFR300 is 1/8" if you add one. This unit filters and regulates only; it does not add lubrication.

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 GAFR300C15ASJN Is Used
Machine tool circuits
Feed a single machining fixture or a small pneumatic clamp station where a steady 0.15-0.9 MPa supply keeps cycle times consistent.
Assembly line stations
Mount on a panel near a workbench to filter and regulate air for handheld screwdrivers or push-in fittings on a dedicated assembly cell.
Test benches
Use on a lab bench to provide clean, regulated air to a pressure gauge or a small valve manifold during equipment testing.
Is the Airtac GAFR Adjustable Filter Regulator GAFR300C15ASJN the Right Air-Prep Unit?
Choose the GAFR300 body for medium-flow lines; it offers a 1/2in port and a 60 cc drain bowl, while the smaller GAFR200 has a 25 cc bowl and the larger GAFR400 holds 100 cc. The metal bowl (C) is a build choice, and the automatic drain (A) suits wet or unattended lines. This model omits the bracket (J) and gauge (N); the 1/8in gauge connection is ready if you add one later. The standard type (S) covers 0.15-0.9 MPa, and the 40 um element is the default. If oil is needed downstream, order the matching GAFC300-15 combination instead. 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 (1/2" 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 GAFR300C15ASJN FAQ
This filter & regulator has a 1/2in port, a working pressure range of 0.15-0.9 MPa (20-130 psi), a maximum pressure of 1.0 MPa (145 psi), and a proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C, has a 60 cc metal drain bowl, and weighs 500 g. The automatic drain clears condensate without manual action.
The N code means no gauge is supplied, but the 1/8in gauge connection is present if you add one. The J code means the mounting bracket is omitted, so you can use an existing panel mount or a custom frame. Both options reduce the initial part count for installations that already have these components.
