The AirTAC GR40010C2 AirTAC Air Pressure Regulator, PT3/8, psi Gauge 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 GR40010C2 is an AirTAC GR400 series air pressure regulator for compressed air, built around the 400 size with a 3/8 in PT port. It is a regulation-only unit: it sets and holds a stable downstream pressure from 0.05 to 0.9 MPa (7-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi). This configuration is fitted with an external round gauge reading in psi, so operators can set and monitor line pressure directly in imperial units. It carries the standard (non low-pressure) regulator type, includes a mounting bracket, and can also be panel-mounted. The GR series operates from -20 to 70 C, a wider temperature window than the rest of the G family, and has no bowl, drain or filter element - it does one job, pressure regulation.
This is a genuine AirTAC part. The GR family spans four sizes (200, 300, 400 and 600) with increasing port sizes and flow capacity, and can be ordered with G (BSPP) or NPT threads, a low-pressure type (up to 0.4 MPa), a round or square gauge in MPa, psi or bar scales, a reverse/check valve, or without a bracket. Flow for this series is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application 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.

On a stamping or assembly press with air-actuated clamps, the GR40010C2 sets the exact cylinder pressure the fixture needs, and the round psi gauge lets the operator verify the setting at a glance during changeovers.
On a cartoning or wrapping line where cylinders and air cylinders drive sealing bars and product pushers, this 3/8 in regulator holds a steady downstream pressure so machine motion stays consistent through the shift.
For an assembly-cell robot with pneumatic grippers, the GR40010C2 provides a dedicated regulated supply at the cell, keeping grip pressure stable and independent of fluctuations in the plant air header.
Start with the port and size step: the GR400 uses a 3/8 in port, and moving up or down a size (200/300/400/600) changes both the connection and the flow capacity, so size the unit against the air demand of the circuit rather than the pipe alone. Because flow is published as curves and not as a single rating, send us your application details and we will confirm sizing from the datasheet before you order. Then settle the options that matter: gauge style and scale (this unit has a round psi gauge; square gauges and MPa or bar scales are alternatives), thread (PT is the standard here, with G/BSPP and NPT available to order), the low-pressure L type if your setpoint stays at or below 0.4 MPa, a reverse/check valve (K) if the downstream circuit needs one, and the bracket (included here; omit it with the J suffix).
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 curves rather than a single rated figure, so we do not quote one number. Send us your application details and we will confirm the datasheet flow figures for the GR400 at your operating conditions on request.
The trailing C2 in GR40010C2 decodes to an external round gauge with a psi scale. Gauges are also available as an embedded square type, and in MPa or bar scales - just tell us which scale you want when ordering, alongside the thread option (PT standard, G/BSPP or NPT).
