The AirTAC GR30010JF2T AirTAC Air Pressure Regulator NPT 3/8 in 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 GR30010JF2T is an AirTAC GR-series air pressure regulator in the 300 size with a 3/8 in NPT port. It performs one job only: reducing and holding downstream air pressure. This configuration is the standard type with a 0.05-0.9 MPa (7-130 psi) adjustment range, a maximum inlet pressure of 1.0 MPa (145 psi), and an embedded square pressure gauge scaled in psi (an external round gauge in MPa, psi or bar scale is available as an option). It is supplied without a mounting bracket, and the GR body is also panel-mountable. As a regulator it has no filter bowl, no drain and no lubricator. Operating temperature is -20 to 70 C, wider than the rest of the G-series families.
This is a genuine AirTAC part. The GR family spans four sizes (200, 300, 400, 600) with port sizes from 1/8 in to 1 in, and options include a low-pressure type (up to 0.4 MPa), a reverse/check valve, gauge scale choice and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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.

| F | Gauge shape: Square. C is round, F is square. |

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 a stable downstream pressure to the clamping cylinders so parts stay held at the same force from cycle to cycle, independent of swings in the shop air supply.
Feed a regulated air line to the cylinders and air chutes on a carton or bag packaging line, with the psi gauge giving operators a local setpoint readout at the machine.
Drop the shop header pressure to the level the machine's pneumatic valves and tool-change cylinders are specified for, mounted at the machine's air inlet panel.
Start with the size and port: 200, 300, 400 and 600 step up in both port size and flow capacity, so match the 3/8 in port here to your supply line and the air your actuator circuit actually uses. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. Then set the options: gauge scale (MPa, psi or bar; this unit ships with a square psi gauge), thread (PT is the standard, G and NPT are order options - this unit is NPT), bracket (J = none) and, if your circuit needs it, the low-pressure type limited to 0.4 MPa or a reverse/check valve. GR is the correct choice when you only need regulation; if you also need water and particulate removal, look at the GFR filter-regulator instead.
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 regulator flow as characteristic curves, not as a single rated number, so there is no one flow figure we can honestly quote. Tell us your line pressure, set pressure and the air your application consumes, and we will confirm the sizing from the datasheet curves on request before you order.
The F2 code in GR30010JF2T specifies the embedded square gauge with a psi scale. If your plant reads in MPa or bar, the GR family also offers those gauge scales, and an external round gauge is available as an option - just specify the scale you want when ordering.
