About the AirTAC GPF300
The AirTAC GPF300 is a GP-series oil mist separator (coalescing filter) that removes oil mist and fine particles with a 0.3 µm or 0.01 µm element at 99.9% efficiency. It has 1/4", 3/8" ports (PT thread as standard). Operating pressure is 0.15 – 1.0 MPa (20 – 145 psi).
Pressure loss is low and the bowl is large. Differential + manual or automatic drains are available, bowls come in PC, nylon or metal, and the unit mounts on its own with a bracket or joins GA-series two- and three-unit sets. Proof pressure 1.5 MPa (215 psi), temperature -5 to +70 °C (no freezing).

Where the GPF300 Is Used
Oil-free air
Removes oil mist ahead of instruments and precision valves.
Clean processes
For painting, packaging and electronics lines.
After a GAF filter
Fit after a general filter for 0.3 or 0.01 µm air.
Choosing the Right GPF300 Configuration
Start with the port size of your air line: 1/4" (08), 3/8" (10).
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 element is M (0.3 µm) or D (0.01 µm); D removes finer particles but passes less flow. A mounting bracket is included unless the code carries J.
AirTAC GPF300 FAQ
1/4" (08), 3/8" (10); PT thread as standard.
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.
M filters to 0.3 µm and D to 0.01 µm, both at 99.9% efficiency; D passes less flow.
