The AirTAC GR40010JF2T 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 AirTAC GR40010JF2T is a pure air pressure regulator from the GR series: it controls downstream pressure only, with no filter element, no drain bowl and no lubricator in its function. This 400-size unit is fitted with a 3/8 in NPT port, a square pressure gauge scaled in psi, and the standard (non low-pressure) regulator type. Maximum working (inlet) pressure is 1.0 MPa (145 psi), the adjustment range is 0.05-0.9 MPa (7-130 psi), and the operating temperature range is -20 to 70 C - wider than the rest of the G-series families. The J suffix means no mounting bracket is supplied, though the GR is also panel-mountable.
This is a genuine AirTAC part. The GR series is available in sizes 200, 300, 400 and 600 with a choice of PT, G or NPT threads, gauge scales in MPa, psi or bar, an optional low-pressure type limited to 0.4 MPa, and an optional reverse/check valve. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures on request before you order.

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.

Drops the 3/8 in branch line off a plant compressor ring to the working pressure a production cell needs, with the psi gauge giving operators a direct local readout at the station.
Sets and holds a stable supply pressure to air cylinders on a clamping or light-press fixture, where consistent downstream pressure keeps cycle force repeatable.
Lets a technician trim the supply pressure to one actuator or valve island on an automated machine independently of the rest of the circuit, panel-mounted next to the module it serves.
Choose your GR size by the port step (1/8 to 1 in across the series) against the flow your line needs - the 400 size with its 3/8 in port suits mid-range circuits. Decide the gauge scale you want (this unit ships with a square gauge in psi; MPa and bar scales are order options), the thread family (PT is the standard, G and NPT are catalogue options - this unit is NPT), and whether you need the low-pressure L type capped at 0.4 MPa or the reverse/check valve K option. Bracket: this code omits it, so plan your own mounting or panel mounting. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 figure, so we do not quote a rated flow, Cv or SCFM number for this unit. Tell us your line pressure and the flow your application needs and we will confirm the sizing against the datasheet curves on request before you order.
The F2 code in GR40010JF2T specifies the embedded square gauge with a psi scale. MPa and bar scales are catalogue options on the same regulator, and an external round gauge is also available - just order the matching code variant. The gauge reads downstream (regulated) pressure only.
