Airtac GAFR Adjustable Filter Regulator GAFR30015SJN
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30015SJN 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 GAFR30015SJN
The GAFR30015SJN 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 GAF and GAR units. This 1/2in port model handles 0.15-0.9 MPa (20-130 psi) and uses a 40 um element to trap solid particles.
Its diversion structure spins the airflow to separate liquid water and drop it into the 60 cc condensate bowl, while the balanced regulator holds the set pressure as supply varies. The pressed-in self-locking knob resists drift from vibration, and since no gauge is fitted, the 1/8in gauge connection is available if you add one later.

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 GAFR30015SJN Is Used
Single actuator control
Feed a single pneumatic actuator or small jig with clean, regulated air at up to 0.9 MPa. The 1/2in port and 500 g body suit a compact machine station.
Instrument air prep
Use the 40 um element to protect sensitive valves or instruments from solid particles. The balanced regulator keeps outlet pressure stable as line supply varies.
Dedicated line filter
Mount this unit on a dedicated air line where you need both filtration and regulation without a lubricator. The 60 cc bowl handles typical condensate between manual drains.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30015SJN the Right Air-Prep Unit?
Choose the GAFR30015SJN when you need a 1/2in port with a 40 um element and a standard 0.15-0.9 MPa range. The PC bowl suits general-purpose lines, while the semi-auto drain plus manual drain gives you both automatic condensate release and a manual override. This model omits the mounting bracket (J) so you can use an existing panel mount, and it ships without a gauge (N) - the 1/8in connection is ready for your own gauge.
For finer filtration, select the W option for a 5 um element, or choose A for an automatic drain on wet lines. If you need lower pressure, the L type tops out at 0.4 MPa. For lubrication downstream, order the matching GAFC300-15 combination. 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 (1/2" 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 GAFR30015SJN FAQ
Pressure range is 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. The drain bowl holds 60 cc, the unit weighs 500 g, and it has a 1/2in port with a 40 um element.
The J code omits the mounting bracket for panel-mount or existing bracket setups, while the N code means no gauge is supplied. The 1/8in gauge connection is still present, so you can add a gauge later if needed.
