The AirTAC GR30010C2T AirTAC Air Pressure Regulator NPT3/8 is a genuine G-series air pressure regulator. It holds a stable downstream pressure over the range 0.05 - 0.9 MPa (7 - 130 psi) with PT3/8" ports, and ships with a pressure gauge. A regulator does not filter the air — put a GF filter upstream, or use a GFR filter regulator, when water and particulate must also be removed.
The GR30010C2T is an AirTAC GR300 series air pressure regulator for compressed air, built to hold a steady downstream pressure regardless of swings in supply. This configuration decodes to a 300 size body with a 3/8 in NPT thread, the standard regulator type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and a round pressure gauge reading in psi fitted so you can set and monitor the outlet pressure directly. A mounting bracket is included, and the GR body is also panel-mountable.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, in PT (standard), G (BSPP) or NPT thread, with embedded square or external round gauges in MPa, psi or bar scales, and an optional low-pressure type rated up to 0.4 MPa. We confirm flow and datasheet figures for your exact model on request.

Specifications follow the official AirTAC G-series air-preparation data. Note the GR temperature range is -20 to +70 °C, wider than the other G-series units. A regulator has no bowl and no filter element, so there is no filtering grade. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, type, bracket, gauge, gauge shape, scale, thread, reflux — a blank position takes the default. Example: GR300-08LNK is a 300 body, PT1/4", low-pressure type, no gauge, with reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom rather than from a single rated figure.

Set and hold the working pressure feeding a bench or C-frame pneumatic press so each stroke acts on the workpiece at the same setpoint, adjustable between 0.05 and 0.9 MPa.
Regulate the air feeding cylinders on a carton sealing or wrapping line, keeping clamp and pusher speeds consistent as the compressor header pressure wanders through the shift.
Drop the supply pressure to a pick-and-place gripper circuit on an assembly cell so delicate parts are held firmly without crushing, with the psi gauge giving the operator a visible setpoint.
Pick the GR size by the port and flow step your line needs: 200 through 600, with ports from 1/8 in up to 1 in - the 300 size here carries a 3/8 in NPT thread. Choose the gauge that matches your practice: embedded square or external round, scaled in MPa, psi or bar (this unit ships with a round psi gauge). Thread is PT as the AirTAC standard, with G (BSPP) and NPT as orderable options - this one is NPT. A bracket is included and the body can also be panel-mounted; a low-pressure type (L) rated up to 0.4 MPa exists where your circuit needs it. Flow for the GR series is published as curves rather than a single rated figure, so ask us to confirm sizing against your application before ordering.
Quick checklist
Without a reflux valve, air cannot flow back through the regulator — order the K option if reverse flow is required. A regulator does not remove water or particulate; that is the filter's job.
AirTAC publishes GR series flow as performance curves rather than a single rated figure, so we do not quote one number. Send us your line pressure, downstream setpoint and expected consumption, and we will confirm the sizing from the datasheet for this 3/8 in model before you order.
The C2 in the code specifies an external round gauge scaled in psi, which suits US-market panels. AirTAC also offers an embedded square gauge and MPa or bar scales across the GR range, so you can order the gauge style and scale that match the rest of your instrumentation.
