Airtac GAF Filter GAF20008AJW
The AirTAC Airtac GAF Filter GAF20008AJW 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 25 cc drain bowl. It is a filter only — it does not regulate or set pressure.

About the Airtac GAF Filter GAF20008AJW
The GAF20008AJW is a genuine AirTAC air filter that spins incoming air to throw liquid water and solid particles into its 25 cc drain bowl, while the 5 um HDPE core traps fine grain. It is a filter only - it has no regulator, no pressure gauge, and no adjusting knob, so it cleans the air but never sets or controls pressure.
This compact 1/4in port unit weighs just 200 g and is rated for 0.15-0.9 MPa (20-130 psi) working pressure with a proof of 1.5 MPa (215 psi). The automatic drain (A) releases condensate without manual attention, and the 5 um element suits precision valves or instrument air. The J code means no mounting bracket is included, so plan for a panel mount or existing bracket.

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 GAFR200 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 GAFR200-08 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 GAF20008AJW Is Used
Protect a precision jig
Feed clean, 5 um filtered air to a small clamping jig or indexing table on a benchtop assembly station, keeping fine dust out of tight pneumatic clearances.
Guard a single solenoid valve
Mount this filter directly upstream of one solenoid valve on a compact machine, preventing water droplets from reaching the valve spool and causing sticking.
Service a portable air tool
Use it on a small workshop cart feeding a die grinder or nailer, with the automatic drain handling condensate when the cart is stored overnight.
Is the Airtac GAF Filter GAF20008AJW the Right Filter?
Choose the GAF200 body for small jigs, single valves, or short airline runs where 1/4in ports match your tubing. The 5 um element (W) traps far finer particles than the standard 40 um, but expect more frequent element service. The automatic drain (A) is ideal for wet or unattended lines, while the missing bracket (J) suits panel mounts or existing hardware. PT threads are the default standard - match your fittings. If the line also needs a set pressure, use the matching GAFR200-08 filter-regulator instead. The GAF600's 205 cc drain bowl holds about 8.2x the condensate of this 25 cc bowl, so size up for high-volume applications.
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 GAFR200
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 25 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 200 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 GAFR200-08 filter-regulator as your air-prep needs grow.
Airtac GAF Filter GAF20008AJW FAQ
Filtering grade is 5 um. Working pressure range is 0.15-0.9 MPa (20-130 psi), proof pressure is 1.5 MPa (215 psi), temperature range is -5 to 70 C. Drain bowl capacity is 25 cc and weight is 200 g. It has a 1/4in PT port and an automatic drain.
The J code omits the mounting bracket for panel-mount or existing bracket setups. The A code specifies an automatic drain that releases condensate automatically, ideal for unattended operation or wet air lines. This unit is filter only - it does not regulate pressure.
