Airtac GAF Filter GAF30015J
The AirTAC Airtac GAF Filter GAF30015J is a genuine compressed-air filter. Its diversion structure spins the air to separate liquid water and trap solid particles down to 40 µm, protecting downstream valves and tools. It has 1/2" ports and a 60 cc drain bowl. It is a filter only — it does not regulate or set pressure.

About the Airtac GAF Filter GAF30015J
The GAF30015J is a genuine AirTAC air filter that spins incoming air to throw liquid water and solid particles into its 60 cc drain bowl, while the HDPE element traps fine grain. It protects downstream valves and cylinders from contamination, but it does not regulate pressure and has no gauge.
This model has a 1/2in port, a 40 um filter element, and a clear PC bowl. It ships without the mounting bracket (J code), so plan for a panel mount or existing bracket. The unit weighs 360 g and its flow curve is plotted to 6000 L/min for sizing against larger or smaller bodies.

Specifications follow the official AirTAC GAF catalogue (pages 225-226). Air must not freeze in the unit. This is a filter only — it separates water and solid particles but does not set or hold a downstream pressure. To regulate pressure as well, use the matching GAFR300 filter-regulator.

A GAF has no regulator and no pressure gauge — there is no type, gauge or reflux code. Need to regulate pressure too? The matching GAFR300-15 is the same filter with a built-in regulator.

Figures are the end of the flow curve plotted in the AirTAC catalogue — a sizing envelope for comparing bodies, not a rated flow. Read the catalogue curve for a real duty point. A filter this size drops less pressure at flow than the same-body GAFR filter-regulator, so match it to your peak demand.

Where the Airtac GAF Filter GAF30015J Is Used
Machine tool air prep
Feed a 1/2in line to a CNC machine's solenoid bank. The 40 um element and 60 cc bowl handle the water load from a reciprocating compressor, and the semi-auto drain lets you purge at shift changes.
Test bench supply
Protect a prototype pneumatic circuit on a lab bench. The 1/2in port matches common test headers, and the clear PC bowl lets you see condensate buildup before it reaches sensitive flow meters.
Assembly station header
Supply a multi-operator assembly station where several tools connect to one drop. The 6000 L/min envelope covers moderate simultaneous use, and the manual drain gives operators a simple daily check.
Is the Airtac GAF Filter GAF30015J the Right Filter?
Choose the GAF300 body for 1/4in to 1/2in port lines where a 60 cc drain bowl and 360 g mass fit the machine layout. The PC bowl suits general shop air; if you need a metal or nylon bowl, order the C or N variant. The blank drain code means both semi-auto and manual drains are fitted, so you can purge condensate either way. Since J is present, the mounting bracket is omitted, so use a panel cutout or your own bracket. The 40 um element handles general pneumatic duty; select the W version for 5 um filtration on precision circuits. The PT thread standard must match your fittings. If the line also needs a set pressure, step up to the GAFR300-15 filter-regulator instead. The GAF300's 6000 L/min flow envelope is 2x the GAF200's 3000 L/min, so this body suits lines that outgrow the smaller unit.
Quick checklist
- ✓ Body size for your peak flow (1/2" here)
- ✓ Element 40 µm (general) or 5 µm (fine)
- ✓ Bowl material: PC (blank), Metal (C), Nylon (N)
- ✓ Drain: semi-auto + manual, or automatic
- ✓ Bracket kept or removed (J)
- ✓ Need pressure control too? Use GAFR300
Installation & Maintenance Notes
- check Install with the airflow arrow: IN to OUT, bowl accessible.
- check Place the filter FIRST in the air-prep train, ahead of any regulator or lubricator.
- check Keep pressure at or below the 1.5 MPa (215 psi) proof limit.
- check Drain condensate before the 60 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 360 g unit on its bracket, not on the tubing.
This is a filter only — it removes water and solid particles but adds no pressure control and no lubrication. Add a GAR regulator, a GAL lubricator, or step up to the GAFR300-15 filter-regulator as your air-prep needs grow.
Airtac GAF Filter GAF30015J FAQ
The GAF30015J is a filter only. It has a 40 um HDPE element, a working pressure range of 0.15-0.9 MPa (20-130 psi), a proof pressure of 1.5 MPa (215 psi), and a temperature range of -5 to 70 C. The drain bowl holds 60 cc and the unit weighs 360 g. It has a 1/2in PT port and no mounting bracket.
The J in GAF30015J means the mounting bracket is not included. You can mount the filter directly to a panel using the body's mounting holes, or use an existing bracket from a previous unit. The body weighs 360 g, so ensure the mounting surface supports it without relying on the tubing.
