Airtac GAF Filter GAF300N10J
The AirTAC Airtac GAF Filter GAF300N10J 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 3/8" ports and a 60 cc drain bowl. It is a filter only — it does not regulate or set pressure.

About the Airtac GAF Filter GAF300N10J
The GAF300N10J is a genuine AirTAC air filter that spins incoming air to throw liquid water and solid particles into its 60 cc nylon bowl, while the 40 um HDPE core traps fine grain. It protects downstream valves and tools from contamination, but it does not regulate pressure and has no gauge.
This 3/8in model weighs 360 g and its flow curve is plotted to 6000 L/min. The nylon bowl is a build choice for the environment; confirm compatibility for aggressive surroundings since no temperature or chemical data is printed. 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 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 GAFR300-10 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 GAF300N10J Is Used
CNC spindle air
Feed a clean 3/8in line to a CNC spindle air curtain or tool changer. The 40 um element and 60 cc bowl handle typical shop condensate, while the semi-auto drain lets you manually purge on a maintenance schedule.
Pneumatic test bench
Protect precision regulators and gauges on a test bench from water and rust particles. The nylon bowl gives a clear view of condensate level, and the 6000 L/min envelope covers multiple test fixtures without a big pressure drop.
Packaging line valves
Guard a bank of solenoid valves on a packaging machine. The 3/8in port suits a branch line, and the 60 cc bowl reduces drain frequency compared to a smaller GAF200, cutting maintenance stops.
Is the Airtac GAF Filter GAF300N10J the Right Filter?
Choose the GAF300 body when you need 1/4in to 1/2in ports and a 60 cc drain bowl, stepping up from the GAF200's 25 cc bowl or down from the GAF400's 100 cc bowl. The nylon bowl suits applications where you prefer a translucent, non-metal build, but verify it against your environment. This model has the semi-auto and manual drains fitted, a 40 um element for general use, and no bracket (J) for panel mounting. The PT port thread must match your fittings; a GAF has no gauge so the thread code only sets the port standard. If you also need a set pressure, use the matching GAFR300-10 filter-regulator instead. The GAF300's 6000 L/min flow envelope is 2x the GAF200's 3000 L/min, giving you a clear sizing step.
Quick checklist
- ✓ Body size for your peak flow (3/8" 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 GAFR300-10 filter-regulator as your air-prep needs grow.
Airtac GAF Filter GAF300N10J FAQ
The GAF300N10J is a filter-only unit with a 3/8in port, 40 um filtering grade, and a 60 cc drain bowl. It weighs 360 g. The working pressure range 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 flow curve is plotted to 6000 L/min. It has a nylon bowl, semi-auto plus manual drain, no bracket, and PT threads.
The J in the code means the mounting bracket is omitted, so you must mount it via a panel or an existing bracket. It is a filter only, not a filter-regulator. If you need pressure control, the GAFR300-10 combines the same filter with a built-in regulator; the GAF300N10J only cleans air and does not set or regulate pressure.
