Airtac GAF Filter GAF200N08AJ
The AirTAC Airtac GAF Filter GAF200N08AJ 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 GAF200N08AJ
The GAF200N08AJ is a filter-only unit that spins incoming air to throw liquid water and solid particles into its 25 cc drain bowl, while the HDPE core traps fine grain. It has no regulator, no gauge and no lubricator - it cleans the air but never controls pressure.
This model uses a 1/4in port, a 40 um element and a nylon bowl, with an automatic drain that clears condensate without manual attention. At 200 g it is the lightest GAF body, so it suits compact machines where the piping, not the unit, carries the weight.

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 GAF200N08AJ Is Used
Compact jig protection
Mount this 200 g filter ahead of a single pneumatic jig or fixture cylinder. The 1/4in port matches small-bore actuators, and the automatic drain keeps the 25 cc bowl from flooding during long production runs.
Bench test rigs
Use it on a lab bench or test stand where space is tight. The nylon bowl resists cracking from accidental knocks better than PC, and the missing bracket lets you bolt it directly to a panel or existing frame.
Portable tool lines
Fit it to a mobile cart feeding one or two air tools. The 3000 L/min curve envelope covers modest tool consumption, while the automatic drain removes water without an operator checking the bowl every shift.
Is the Airtac GAF Filter GAF200N08AJ the Right Filter?
Choose the GAF200 body for small jigs or single-valve protection, and step up to a GAF300 (60 cc bowl, 6000 L/min curve) when the line feeds several actuators. The nylon bowl is a build choice - confirm compatibility with aggressive surroundings since no chemical data is printed. The A drain is automatic for wet or unattended lines, while the J code omits the bracket for panel mounting. This unit runs a 40 um element with PT ports; pick the W code for 5 um filtration or G/T for other thread standards. If you also need 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 GAF200N08AJ FAQ
This filter-only unit has a 40 um HDPE element, a working pressure range of 0.15-0.9 MPa (20-130 psi), a proof pressure of 1.5 MPa (215 psi), and a temperature range of -5 to 70 C. The drain bowl holds 25 cc and the unit weighs 200 g, with a flow curve plotted to 3000 L/min.
The A code specifies an automatic drain that discharges condensate automatically, ideal for wet lines or unattended operation. This model has no manual drain option - the automatic type handles all bowl emptying without operator intervention.
