Airtac GAF Filter GAF300C15A
The AirTAC Airtac GAF Filter GAF300C15A 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 1/2" ports and a 60 cc drain bowl. It is a filter only — it does not regulate or set pressure.

About the Airtac GAF Filter GAF300C15A
The GAF300C15A is a filter-only unit that spins incoming air to throw liquid water and solid particles into its 60 cc metal bowl, while the HDPE core traps fine grain. It is not a regulator and carries no pressure gauge, so it cleans the air without attempting to control pressure.
This model uses a 1/2in port and a 40 um element, with an automatic drain that clears condensate by itself. Its 360 g mass and 60 cc bowl place it in the mid-size class, a step up from the GAF200's 25 cc bowl for lines that need fewer drain checks.

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 GAFR300-15 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 GAF300C15A Is Used
Machine Tool Protection
Feed a 1/2in line to a CNC coolant valve or a precision jig, where the 40 um element and automatic drain keep water from reaching sensitive solenoids.
Assembly Station Air
Supply a multi-spindle nutrunner or a pneumatic press at a workbench, using the 60 cc bowl to collect condensate over a full shift before any manual check.
Process Line Pre-Filter
Protect a bank of valves on a packaging line, where the metal bowl resists rough handling and the automatic drain runs unattended in a wet compressor room.
Is the Airtac GAF Filter GAF300C15A the Right Filter?
Choose the GAF300 body when 1/2in piping and a 60 cc condensate bowl match your duty, or step down to the GAF200 for lighter lines with a 25 cc bowl. The metal bowl suits demanding environments, but confirm compatibility for aggressive surroundings since no chemical data is printed. The automatic drain handles wet or unattended lines, while the included bracket simplifies panel mounting, and the 40 um element covers general filtration needs. If you also need pressure control, pair this filter with a GAR regulator or use the GAFR300-15 filter-regulator instead. The 1.5 MPa proof pressure is about 1.67x the 0.9 MPa top of the working range, giving a solid burst-test margin.
Quick checklist
- ✓ Body size for your peak flow (1/2" 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 GAFR300-15 filter-regulator as your air-prep needs grow.
Airtac GAF Filter GAF300C15A 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. Its drain bowl holds 60 cc and the unit weighs 360 g.
The A code means an automatic drain that expels condensate without manual intervention, ideal for wet or unattended lines. This model also has a metal bowl, which is a build choice, but you should confirm it suits your environment since no chemical compatibility data is printed.
