The AirTAC GR30010F1T 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 GR30010F1T is an AirTAC GR-series air pressure regulator: it does one job, holding downstream pressure steady at the value you set, and it contains no filter, no bowl and no lubricator. This 300-size unit is fitted with a 3/8 in NPT port and carries the standard adjustment range of 0.05-0.9 MPa (7-130 psi). The F1 suffix means a square pressure gauge with an MPa scale is included, embedded in the body, so the set pressure is visible at a glance. Maximum inlet pressure is 1.0 MPa (145 psi), and the GR series handles a wider temperature span than the rest of the G family: -20 to 70 C.
This is a genuine AirTAC part. The GR line spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options include G (BSPP) or NPT threads in place of the PT standard, psi or bar gauge scales, an external round gauge, a low-pressure type limited to 0.4 MPa, a reverse/check valve, and panel mounting. Flow figures for this series are published as curves rather than a single rating, so ask us and we will confirm the datasheet numbers 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.

Set a stable, repeatable downstream pressure for a clamping or light-press circuit on a production machine, so every cycle actuates at the same setpoint regardless of supply swings.
Feed cylinders and actuators on a packaging or cartoning line from a regulated branch circuit, keeping seal bars, pushers and diverters running at their specified pressure.
Drop a plant air header down to a lower, dedicated pressure for one sub-circuit - grippers, air tables or test fixtures - without disturbing the pressure set on the rest of the system.
Start with the port size: this unit is 300 size with a 3/8 in NPT port, and the GR range steps through 200/300/400/600, so pick the size whose flow curve covers your air demand with margin - we can check the curve against your consumption before you order. Set the downstream pressure anywhere in the 0.05-0.9 MPa (7-130 psi) range; if your circuit must run below that, the L low-pressure variant caps at 0.4 MPa. The embedded square gauge here reads in MPa; psi and bar scales are available, and an external round gauge can be specified instead. Thread is NPT on this code; PT is the catalogue standard and G (BSPP) is also offered. A reverse/check valve (K) can be added to hold downstream pressure if the supply fails, and a mounting bracket is included - GR is also panel-mountable. Because flow is published as curves rather than a single rated figure, send us your application details and we will confirm sizing 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-series flow as characteristic curves rather than a single rated number, so we do not quote a flow figure for this unit. Send us your application details and we will confirm the datasheet curve and sizing on request before you order.
F means the square gauge is fitted and 1 means it reads in MPa, so this unit ships with an embedded square MPa gauge as standard. Psi (scale 2) and bar (scale 3) square gauges are available, as is an external round gauge - specify the scale you want when ordering.
