The AirTAC GR40010JC1T 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 GR40010JC1T is an AirTAC GR-series air pressure regulator: it does one job, holding your downstream pressure steady at the setting you choose, between 0.05 and 0.9 MPa (7-130 psi). This 400-size unit is configured with a 3/8 in NPT port, the standard regulator type, a round pressure gauge with an MPa scale, and no mounting bracket; like all GR units it can also be panel-mounted. It carries no bowl, filter or drain, because a regulator has nothing to collect - it only regulates. Maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -20 to 70 C, wider than the rest of the G series.
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 and NPT threads, with optional low-pressure type (up to 0.4 MPa), reverse/check valve, bracket and gauge choices. Flow 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.

| 10 | Port size PT3/8". This body offers 10 = PT3/8", 15 = PT1/2". |
| (blank) | Standard type — 0.05 - 0.9 MPa (7 - 130 psi). Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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 a stable, reduced pressure feeding the pneumatic cylinders and grippers on a packaging machine, so carton sealing and case erecting stations run at a consistent setting regardless of header pressure swings.
Drop line pressure to the level a machining centre's tool-clamp or pallet-clamp circuit was designed for, with the round MPa gauge giving the operator a clear local reading of the set pressure.
Trim the atomising air pressure at the booth wall for spray guns and air-assisted applicators, where the setting is tuned by hand and held steady through the shift.
Start with the port: this unit is 3/8 in NPT, and the GR family steps through 1/8, 1/4, 3/8, 1/2, 3/4 and 1 in across sizes 200 to 600 - pick the size whose flow curve covers your demand. Then set the gauge: this configuration has a round external gauge on an MPa scale, with psi and bar scales available if you prefer. Thread is a real choice too: PT is the catalogue standard, while G (BSPP) and NPT (as here) are ordered options - specify the one that matches your piping. Decide on a bracket (this unit has none, but GR is panel-mountable as standard) and, if your circuit needs it, the reverse/check valve option or the low-pressure type capped at 0.4 MPa. Because flow is published as curves and not a single rating, send us your application details and we will confirm sizing against the datasheet before you order.
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 flow as curves, not as a single rated figure, so we do not quote a number here. Tell us your inlet pressure, set pressure and expected air demand, and we will confirm the flow figures from the datasheet for this exact model on request before you order.
C is the round external pressure gauge and 1 is the MPa scale, so this unit arrives with a round MPa gauge fitted. Square embedded gauges and psi (scale 2) or bar (scale 3) scales are catalogue options on GR regulators - just order the code with the gauge suffix you want.
