The AirTAC GR40010F1T 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 GR40010F1T is an AirTAC GR-series air pressure regulator: it does one job, holding a stable downstream pressure from a compressed-air supply, and it carries no filter element, no bowl and no drain. This 400-size unit is decoded as a 3/8 in NPT port, standard regulation range of 0.05-0.9 MPa (7-130 psi), a maximum inlet pressure of 1.0 MPa (145 psi), and a fitted embedded square gauge scaled in MPa. The trailing T in the code specifies the NPT thread option, and the unit includes a mounting bracket; the GR series is also panel-mountable. Its operating temperature span of -20 to 70 C is wider than the rest of the G family, which suits colder installations.
This is a genuine AirTAC part. The GR series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, thread options PT (standard), G and NPT, gauge scales in MPa, psi or bar, an optional low-pressure type, and an optional reverse/check valve. 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.

| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |

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 steady clamp pressure to a fixture's clamping cylinders on a CNC or drilling station, so workholding force stays consistent across every cycle. The 3/8 in NPT port suits a dedicated clamp-air branch, and the MPa gauge lets operators read the setting directly.
Feed a stable regulated supply to the cylinders and actuators on a carton or bag packaging line, where fluctuating plant air would upset sealing and forming motions. The wide -20 to 70 C range suits cold rooms or unheated plant corners.
Drop the header pressure to the lower working pressure a robot end-effector or gripper circuit actually needs, trimmed locally at the cell. The embedded square gauge gives a clear local reading, and the mounting bracket or panel mounting keeps the regulator fixed at the point of use.
Step up or down the GR size ladder (200 / 300 / 400 / 600) to match the port and flow path your line needs - this 400 size carries a 3/8 in port. Choose the gauge scale that matches your plant instruments (MPa, psi or bar); this unit ships with the square MPa gauge, and an external round gauge is available as an option. Thread is NPT on this code; PT is the AirTAC standard and G is the other order option. If your line can accept it, the optional reverse/check valve keeps downstream pressure intact when upstream supply drops, and the low-pressure type covers setpoints up to 0.4 MPa.
Sizing honestly: AirTAC publishes GR flow as curves, not a single rated number, so we do not quote a flow figure here. Tell us your line pressure, set pressure and expected air demand, and we will confirm the right size against the datasheet curves 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 performance curves rather than a single rated figure, so we do not state a flow number for this regulator. Send us your inlet pressure, set pressure and expected air consumption, and we will confirm the sizing against the datasheet curves on request before you order.
The trailing T in GR40010F1T decodes to the NPT thread option. PT is the AirTAC standard thread, and G (BSPP) is also a catalogue option - all three are ordering specifications on the same 3/8 in port size, so choose the thread that matches your piping system when you order.
