Airtac GAF Filter GAF30008J
The AirTAC Airtac GAF Filter GAF30008J 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 1/4" ports and a 60 cc drain bowl. It is a filter only — it does not regulate or set pressure.

About the Airtac GAF Filter GAF30008J
The GAF30008J 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 40 um HDPE element traps fine grain. It has no regulator, no gauge and no lubricator - it only cleans the air.
This 1/4in port model weighs 360 g and is built for a GAF300 body. The clear PC bowl lets you see condensate buildup at a glance. With the J code, the mounting bracket is omitted, so plan for a panel mount or an existing bracket when installing.

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 GAFR300-08 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 GAF30008J Is Used
CNC spindle air
Protect a CNC spindle's air seals and tool changer from water droplets and machining dust before they reach precision components.
Bench test rigs
Feed clean air to a laboratory test jig or calibration bench where a 1/4in line and a 40 um filter keep instruments free of particulates.
Paint spray booth
Install upstream of a spray gun in a small booth to remove condensed water that would otherwise cause pinholes in the finish.
Is the Airtac GAF Filter GAF30008J the Right Filter?
Choose the GAF30008J when you need a 1/4in filter with a 40 um element and a semi-auto drain plus manual backup. The PC bowl is the standard build choice; confirm compatibility for aggressive environments. The J code means no bracket is included, so use a panel mount or your own bracket. The PT thread standard matches common local fittings. For pressure control, use the matching GAFR300-08 filter-regulator instead. The GAF300's 6000 L/min flow envelope is double the GAF200's 3000 L/min, giving you room to grow.
Quick checklist
- ✓ Body size for your peak flow (1/4" 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 GAFR300-08 filter-regulator as your air-prep needs grow.
Airtac GAF Filter GAF30008J FAQ
This is a 1/4in port air filter with a 40 um HDPE element, a 60 cc PC drain bowl, and a weight of 360 g. The working pressure range is 0.15-0.9 MPa (20-130 psi), proof pressure is 1.5 MPa (215 psi), and the temperature range is -5 to 70 C. The flow curve is plotted to 6000 L/min. It has a semi-auto drain plus a manual drain, and no mounting bracket.
The J in the model code means the mounting bracket is omitted. This is for installations where you already have a bracket, or where you plan to panel-mount the filter. The filter body itself is identical to bracketed versions; only the included accessory is different.
