Airtac GAFR Adjustable Filter Regulator GAFR30015ASJW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30015ASJW 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 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 GAFR30015ASJW
The GAFR30015ASJW is a filter and regulator combined in a single body, so one compact unit cleans the air and stabilizes outlet pressure. It handles a 1/2in port and delivers a standard 0.15-0.9 MPa (20-130 psi) range, with a 5 um element that traps finer particles for sensitive equipment.
This model ships with an automatic drain, a PC bowl, and a fitted circular gauge reading MPa/psi. The diversion structure spins the flow to separate liquid water and solid debris into the 60 cc condensate bowl, keeping the downstream line clean without needing a separate filter unit.

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 GAFR30015ASJW Is Used
Precision valve control
Feed a bank of precision pneumatic valves that need stable pressure and fine filtration to avoid clogging or erratic cycling.
Machine header supply
Mount on a machine header to condition air for multiple actuators, using the 5 um element to protect tight-clearance components.
Instrument air line
Use in a small instrument air line where the 5 um filtration and steady regulation keep sensitive gauges and controllers accurate.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30015ASJW the Right Air-Prep Unit?
Choose the GAFR300 body when you need a 1/2in port and a 500 g unit that suits a machine header or a small multi-station line. The 5 um element (W) is the finer filtration option versus the standard 40 um, ideal for precision valves or instrument air but requiring more frequent element service. The automatic drain (A) handles wet or unattended lines, while the J code means no mounting bracket is included, so plan for a panel mount or existing bracket. The PT thread comes with an MPa/psi gauge scale, and the blank reflux code means no reverse-flow valve is fitted. If the line needs lubrication downstream, order the matching GAFC300-15 combination instead. With a 1.0 MPa max supply, you get about 0.1 MPa of headroom above the 0.9 MPa top of the regulated 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 GAFR30015ASJW FAQ
This filter & regulator has a 1/2in port, a standard pressure range of 0.15-0.9 MPa (20-130 psi), a max 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 drain bowl, and weighs 500 g. The element is 5 um and the drain is automatic.
The J code in GAFR30015ASJW means the mounting bracket is not included. This suits installations where the unit is panel-mounted or attached to an existing bracket, saving cost and space. You can still mount it securely, but you must provide the bracket yourself.
