Airtac GAF Filter GAF30008AJW
The AirTAC Airtac GAF Filter GAF30008AJW is a genuine compressed-air filter. Its diversion structure spins the air to separate liquid water and trap solid particles down to 5 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 GAF30008AJW
The GAF30008AJW 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 5 um HDPE element traps fine grain. It is a filter only, with no regulator, gauge, or lubricator, protecting downstream valves and tools from contamination.
This model has a 1/4in port, a clear PC bowl, and an automatic drain that clears condensate without manual attention. Weighing 360 g, it is a compact GAF300 body whose flow curve is plotted to 6000 L/min, making it a solid choice for a single machine station or a small control cabinet.

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.

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 GAF30008AJW Is Used
CNC Coolant Valves
Feed clean, 5 um filtered air to the solenoid valves on a CNC lathe's coolant system, preventing sticky particles from jamming spools and extending valve life.
Test Bench Air Supply
Protect a laboratory test bench's precision pressure sensors and flow meters from water droplets and rust scale, ensuring accurate readings on a 1/4in line.
Pick-and-Place Gripper
Supply filtered air to a pneumatic gripper on an assembly robot, keeping the cylinder's seals clean and the automatic drain handling condensate from a humid plant.
Is the Airtac GAF Filter GAF30008AJW the Right Filter?
Choose the GAF300 body when you need a 1/4in port and a 60 cc drain bowl, stepping down from a GAF400's 100 cc bowl if space is tight. The PC bowl suits general industrial air, while the automatic drain (A) handles wet or unattended lines, and the 5 um element (W) protects precision valves. This unit ships without a bracket (J), so plan a panel mount, and use PT threads to match your piping. If you also need pressure control, pair it with a GAR regulator or step up to the GAFR300-08 filter-regulator. The GAF300's 6000 L/min flow envelope is twice the GAF200's 3000 L/min, giving you headroom 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 GAF30008AJW FAQ
It is a 5 um air filter with a 1/4in port, a 60 cc drain bowl, and a weight of 360 g. The working pressure range is 0.15-0.9 MPa (20-130 psi), with a proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C and must not freeze.
The 'A' code means an automatic drain, which expels accumulated condensate without manual intervention. This is ideal for wet lines or unattended operation, unlike the semi-auto+manual drain on blank models that requires periodic checking.
