Airtac GAF Filter GAF300N08A
The AirTAC Airtac GAF Filter GAF300N08A 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 60 cc drain bowl. It is a filter only — it does not regulate or set pressure.

About the Airtac GAF Filter GAF300N08A
The GAF300N08A is a filter-only unit that spins incoming air to throw liquid water and solid particles into its 60 cc nylon bowl, while the 40 um HDPE element traps fine grain. It has no regulator and no gauge, so it cleans the air but never sets pressure.
This 1/4in model weighs 360 g and carries a nylon bowl, which is a build choice rather than a performance upgrade. With an automatic drain fitted, it suits lines where regular manual draining is impractical, and its flow curve is plotted to 6000 L/min for sizing against larger or smaller bodies.

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.

A GAF has no regulator and no pressure gauge — there is no type, gauge or reflux code. Need to regulate pressure too? The matching GAFR300-08 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 GAF300N08A Is Used
Single valve protection
Protect a single solenoid valve or small cylinder on a 1/4in line. The 40 um element and automatic drain keep water and rust from reaching the valve, while the 360 g body mounts easily on a frame or panel.
Instrument air pre-filter
Use it ahead of a pressure regulator or flow meter on a test bench. It removes liquid water and solid grain first, so downstream components see cleaner air and need less frequent service.
Unattended machine line
Fit it on a packaging or assembly machine where operators cannot drain bowls regularly. The automatic drain ejects condensate by itself, and the 60 cc bowl provides buffer capacity between cycles.
Is the Airtac GAF Filter GAF300N08A the Right Filter?
Choose the body and port first: GAF300 offers 1/4in, 3/8in and 1/2in ports, while the smaller GAF200 tops out at 1/4in with a 25 cc bowl, and the larger GAF400 starts at 3/8in with a 100 cc bowl. The nylon bowl here is a material choice with the same common specification as PC or metal, so confirm compatibility for aggressive surroundings. The automatic drain (A) handles wet or unattended lines, the included bracket supports panel mounting, and the 40 um element covers general duty while a W code switches to 5 um. Thread is PT, so match your fittings accordingly. If the line needs a set pressure, use the matching GAFR300-08 filter-regulator instead. The 60 cc bowl holds about 2.4x the condensate of the GAF200's 25 cc, meaning fewer drain checks on this body.
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 GAF300N08A FAQ
It is a filter-only unit with a 40 um HDPE element, a 1/4in port, and a 60 cc nylon drain bowl. 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. The unit weighs 360 g and its flow curve is plotted to 6000 L/min.
The A code means an automatic drain, which discharges collected condensate without manual intervention. It is ideal for wet lines or locations where an operator cannot drain the bowl on a schedule. The alternative blank code ships with both semi-auto and manual drains.
