About the AirTAC GC300-15
The AirTAC GC300-15 is a G-series three-unit air preparation set: GF filter, GR regulator and GL lubricator joined together. It has 1/2" ports (PT thread as standard, G also stocked). It regulates from 0.15 to 0.9 MPa (20-130 psi) with automatic or differential-pressure drain, and from 0.05 to 0.9 MPa (7-130 psi) with manual drain. The low-pressure (L) version regulates up to 0.4 MPa (58 psi).
The lubricator's sealed side-window drip design keeps the oil feed stable, the feed is set within one turn of the adjuster, and oil can be topped up without shutting off the air. The units join with a quick, secure connector. Manual, differential-pressure and automatic drains are available. Maximum operating pressure is 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi), operating temperature -5 to +70 °C (no freezing).

Where the GC300-15 Is Used
Machine air inlet
Fit the GC300-15 where compressed air enters a machine.
Stable working pressure
Set and hold the pressure your valves and cylinders need.
Pneumatic stations
Feeds cylinders, valves and tools on one air line.
Choosing the Right GC300-15 Configuration
Start with the drain and type. Automatic drain (A) empties the bowl on its own, for lines with a lot of condensate. Manual drain (M) is opened by hand and also works at low pressure. The standard differential-pressure drain releases water when line pressure drops. Low-pressure (L) versions regulate up to 0.4 MPa (58 psi).
Then the pressure gauge: square (F) or round (C), reading in MPa (1), psi (2) or bar (3), or no gauge (N) if you read pressure elsewhere.
Finally the configuration. The 40 µm element is standard; W gives a 5 µm element for cleaner air. Thread is PT unless the code ends in G (G thread) or T (NPT), before any K. K adds a check valve.
AirTAC GC300-15 FAQ
It regulates from 0.15 to 0.9 MPa (20-130 psi) with automatic or differential-pressure drain, and from 0.05 to 0.9 MPa (7-130 psi) with manual drain. Low-pressure (L) versions go up to 0.4 MPa (58 psi).
1/2" (15), PT thread as standard; G = G at the end of the code.
F = square gauge, C = round gauge, followed by the scale: 1 = MPa, 2 = psi, 3 = bar. N means no gauge.
