About the AirTAC GR400-15

The AirTAC GR400-15 is a G-series air pressure regulator. It has 1/2" ports (PT thread as standard, G and NPT also stocked). It regulates from 0.05 to 0.9 MPa (7-130 psi). The low-pressure (L) version regulates up to 0.4 MPa (58 psi).

The pressure gauge is a built-in square type (a round external gauge can be chosen), the knob locks by pressing it in, and a balanced valve keeps the set pressure stable. A bracket or panel mounting is available. Maximum operating pressure is 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi), operating temperature -20 to +70 °C.

Where the GR400-15 Is Used

Machine air inlet

Fit the GR400-15 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 GR400-15 Configuration

Start with the type: standard, or low-pressure (L) when the set pressure must stay at or below 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. A mounting bracket is included unless the code carries J. Thread is PT unless the code ends in G (G thread) or T (NPT), before any K. K adds a check valve.

AirTAC GR400-15 FAQ

It regulates from 0.05 to 0.9 MPa (7-130 psi). Low-pressure (L) versions go up to 0.4 MPa (58 psi).

1/2" (15), PT thread as standard; G = G, T = NPT 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.

No. You can order a single GR400-15. Orders are processed and handed to the carrier within 3-5 business days.
