About the AirTAC GF300
The AirTAC GF300 is a G-series compressed-air filter. It separates condensed water and filters out particles through a 40 or 5 µm element, with a polycarbonate (PC) bowl and 1/4"-1/2" ports (PT as standard, NPT also stocked). A filter only cleans the air; it does not set downstream pressure. Pair it with a GR regulator, or use a GFR filter regulator when pressure control is needed.
The maximum inlet pressure is 1.0 MPa (145 psi). Automatic and differential-pressure drain versions work from 0.15 to 1.0 MPa (22-145 psi); the manual-drain version works from 0 to 0.9 MPa (0-131 psi). Operating temperature is -5 to +70 °C with no freezing. Pressure loss through the element is low.

Where the GF300 Is Used
Machine air inlet
Fit the GF300 where compressed air enters a machine to stop water and dirt reaching valves and cylinders.
Condensate removal
The bowl collects condensed water from the compressor line; the drain type decides how it is emptied.
Before regulators and precision parts
Install ahead of a GR regulator or sensitive valves; use the 5 µm element where cleaner air is needed.
Choosing the Right GF300 Configuration
Start with the port size. Match the GF300 port to the pipe or fitting it connects to: 1/4" (08), 3/8" (10), 1/2" (15).
Then choose the drain. Automatic drain (A) empties the bowl on its own, which suits lines with a lot of condensate or machines that run unattended. Manual drain (M) is opened by hand; it also works at low line pressure, from 0 MPa. The standard differential-pressure drain releases water when line pressure drops, for example at shutdown.
Finally the configuration. The 40 µm element is standard for general machine air; choose 5 µm (W) in front of precision valves and instruments. A mounting bracket is included unless the code carries J. For North American NPT piping pick the T (NPT thread) version. Codes with C after the body size are AirTAC's C-body version, priced separately; ask us if you need to match an existing C unit.
AirTAC GF300 FAQ
No. The GF300 only filters water and particles. Use a GR regulator after it, or a GFR filter regulator that combines both.
1/4" (08), 3/8" (10), 1/2" (15). PT thread is standard; NPT versions carry T at the end of the code.
Automatic drain for heavy condensate or unattended machines, manual drain when you empty the bowl by hand or run at very low pressure, and the standard differential-pressure drain for general use.
40 µm as standard. The W code gives a 5 µm element.
Up to 1.0 MPa (145 psi) inlet pressure and -5 to +70 °C with no freezing. Manual-drain versions are rated 0 to 0.9 MPa.
No. You can order a single GF300. Orders are processed and handed to the carrier within 3-5 business days.
