Airtac GAF Filter GAF200N08J
The AirTAC Airtac GAF Filter GAF200N08J 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 25 cc drain bowl. It is a filter only — it does not regulate or set pressure.

About the Airtac GAF Filter GAF200N08J
The GAF200N08J 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 40 um HDPE element traps fine grain. It has a 1/4in port and weighs just 200 g, making it a compact first-stage guard for a single valve or small jig.
This filter-only unit cleans the air but does not regulate pressure, so there is no gauge and no adjusting knob. Its nylon bowl is a build choice for the environment, and since the bracket is omitted (J), you must mount it on a panel or existing frame rather than support it from the tubing.

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 GAF200N08J Is Used
Protect a precision jig
Mount this 200 g filter on a small assembly jig with a single pneumatic clamp. Its 40 um element keeps water and rust flakes from scoring the clamp's sliding surfaces, and the 25 cc bowl is easy to drain between batches.
Guard a bench-top valve
Feed a manual air valve on a workbench with this compact filter. The diversion structure spins out liquid water before it reaches the valve's internal seals, extending their life in a humid shop.
Clean air for a test rig
Use this filter on a small pneumatic test rig where a clean, dry air supply is critical for repeatable readings. The 40 um element removes solid particles that could clog orifices, and the manual drain lets you purge condensate before each test run.
Is the Airtac GAF Filter GAF200N08J the Right Filter?
Choose the GAF200 body for small machines with 1/8in or 1/4in ports; if you need more flow, step up to the GAF300 (60 cc bowl, curve to 6000 L/min). The nylon bowl is a material choice, the semi-auto plus manual drain lets you purge condensate by hand or automatically when pressure drops, and the missing J bracket means you must supply your own panel mount. The 40 um element suits general shop air, while the PT thread standard must match your fittings. If the line also needs a set pressure, use the matching GAFR200-08 filter-regulator instead. The 1.5 MPa proof pressure is about 1.67x the 0.9 MPa top of the working range, a burst-test margin rather than a running limit.
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 GAF200N08J FAQ
This AirTAC GAF200N08J is a filter only with a 1/4in PT port, a 40 um HDPE element, and a 25 cc nylon drain bowl. It weighs 200 g, has a working pressure range of 0.15-0.9 MPa (20-130 psi), a proof pressure of 1.5 MPa (215 psi), and operates from -5 to 70 C. The flow curve is plotted to 3000 L/min.
The J in the model code means the standard mounting bracket is omitted. This is for installations where you already have a panel mount or an existing bracket. You must secure the 200 g unit to a rigid frame or panel; do not support it from the air tubing alone.
