About the AirTAC GAF300
The AirTAC GAF300 is a GA-series compressed-air filter. It has 1/4", 3/8", 1/2" ports (PT thread as standard, G also stocked). Operating pressure is 0.15 – 0.9 MPa (20 – 130 psi).
A swirl guide spins the incoming air so water and solid particles separate out before the 40 µm or 5 µm element. Pressure drop is low, water separation is high and the bowl is large; bowls come in PC, metal or nylon, and a mounting bracket is optional. Proof pressure 1.5 MPa (215 psi), temperature -5 to +70 °C (no freezing).

Where the GAF300 Is Used
Machine air inlet
Removes water and particles where compressed air enters a machine.
Protecting valves
Clean air extends the life of valves and cylinders.
Before a regulator
Fit ahead of a GAR regulator or GPR.
Choosing the Right GAF300 Configuration
Start with the port size of your air line: 1/4" (08), 3/8" (10), 1/2" (15).
Then the bowl and drain: PC is standard, C is metal and N is nylon; the standard drain is differential + manual, A gives an automatic drain.
Finally the configuration. The 40 µm element is standard; W gives a 5 µm element for cleaner air. A mounting bracket is included unless the code carries J. The thread is PT unless the code carries G (G thread) or T (NPT).
AirTAC GAF300 FAQ
1/4" (08), 3/8" (10), 1/2" (15); PT thread as standard, G also stocked.
PC is the standard clear bowl; C (metal) suits areas with solvents or impact risk; N is nylon. The standard drain is differential + manual; A drains automatically.
