Airtac GAF Filter GAF200N08AJW
The AirTAC Airtac GAF Filter GAF200N08AJW 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 GAF200N08AJW
The GAF200N08AJW is a genuine AirTAC air filter that spins incoming air to throw liquid water and solid particles into its 25 cc nylon drain bowl, while the 5 um HDPE element traps fine grain. It is a filter only - it has no regulator, no pressure gauge, and no adjusting knob.
This 1/4in model weighs 200 g and uses a nylon bowl with an automatic drain, so it clears condensate by itself on wet or unattended lines. The 5 um element suits precision valves and instrument air, and the unit carries a PT port thread standard.

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 GAF200N08AJW Is Used
Protect a precision valve
Feed a single 1/4in pilot valve or small jig cylinder with air cleaned to 5 um, keeping fine abrasive grain out of the spool and seals.
Instrument air for a lab fixture
Use the 5 um element ahead of a bench-top pneumatic test fixture where particle carryover could skew readings or clog orifices.
Unattended drip leg
Mount this 200 g filter on a panel with the automatic drain to handle condensate on a lightly used line that is not checked daily.
Is the Airtac GAF Filter GAF200N08AJW the Right Filter?
Choose the GAF200 body for 1/8in or 1/4in ports, and step up to the GAF300 (60 cc bowl, 6000 L/min curve) when a line needs more condensate capacity. The nylon bowl is a build choice - confirm compatibility for aggressive surroundings since no chemical data is printed. This model has the automatic drain (A), omits the bracket (J) for panel mounting, and uses the 5 um element (W) with PT threads. If the line also needs a set pressure, use the matching GAFR200-08 filter-regulator instead. The 1.5 MPa proof pressure gives about a 1.67x margin over the 0.9 MPa top of the working range.
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 GAF200N08AJW FAQ
It is a 1/4in port air filter with a 5 um HDPE element, 25 cc nylon drain bowl, and 200 g weight. Working pressure is 0.15-0.9 MPa (20-130 psi), proof pressure is 1.5 MPa (215 psi), and temperature range is -5 to 70 C. It has an automatic drain and no mounting bracket.
The nylon bowl is a material choice for the drain bowl, and the automatic drain (A) clears condensate without manual attention, which suits wet or intermittent lines. The J code means no bracket is included, so plan for a panel mount or an existing bracket.
