Airtac GAF Filter GAF300N10JW
The AirTAC Airtac GAF Filter GAF300N10JW 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 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 GAF300N10JW
The GAF300N10JW is a filter-only unit that spins incoming air to throw liquid water and solid particles into its 60 cc nylon drain bowl, while the 5 um HDPE core traps fine grain. It protects downstream valves and cylinders from contamination without any pressure regulation function.
This model uses a 3/8in port and weighs 360 g, placing it in the mid-size GAF300 class. The nylon bowl is a build choice for the environment; confirm compatibility for aggressive surroundings since no chemical or temperature data is printed.

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 GAF300N10JW Is Used
Precision valve protection
Feed a bank of precision pneumatic valves on a small assembly station. The 5 um element stops fine abrasive grain that could degrade spool valve performance, while the 60 cc bowl holds condensate between shifts.
Machine tool air prep
Protect a CNC machine's pneumatic clamping system from water carryover. The diversion structure separates liquid efficiently, and the 3/8in port matches typical machine tool supply lines.
Portable pneumatic tool line
Mount this filter ahead of a pneumatic grinder or drill on a service cart. The 360 g weight is manageable for a frame, and the 5 um element keeps tool internals cleaner than a standard 40 um unit.
Is the Airtac GAF Filter GAF300N10JW the Right Filter?
Choose the body and port first: GAF300 offers 1/4in, 3/8in and 1/2in ports with a 60 cc bowl, while the smaller GAF200 (25 cc) suits lighter lines and the larger GAF400 (100 cc) handles higher volumes. The nylon bowl here is a material choice; the PC (blank) or metal (C) options share the same spec. This unit ships without the mounting bracket (J), so plan for panel mounting or an existing bracket. The 5 um element traps finer particles than the standard 40 um for precision applications, at the cost of more frequent service. PT thread is the port standard; G and NPT are alternatives. If you 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 curve, showing the sizing step between these bodies.
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 GAF300N10JW FAQ
This is a 3/8in port air filter with a 5 um HDPE element, nylon bowl, and semi-auto plus manual drains. Working pressure is 0.15-0.9 MPa (20-130 psi), proof pressure is 1.5 MPa (215 psi), temperature range is -5 to 70 C, drain bowl capacity is 60 cc, and weight is 360 g. The flow curve is plotted to 6000 L/min.
The J in GAF300N10JW means the mounting bracket is omitted from the package. This suits installations where the filter mounts to an existing panel, frame, or machine structure rather than using the standard bracket. You would need to provide your own mounting solution or order the version without J to get the bracket included.
