The AirTAC GR40015JF1T AirTAC Air Pressure Regulator NPT1/2 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 PT1/2" 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 GR40015JF1T is an AirTAC GR-series air pressure regulator for compressed air only. It does one job: reducing and holding a stable downstream pressure. This 400-size unit has NPT1/2 ports, a standard regulation range of 0.05-0.9 MPa (7-130 psi), and a maximum inlet pressure of 1.0 MPa (145 psi). The trailing F1 in the code means a square pressure gauge fitted with an MPa scale, so the set pressure is readable at the unit. The J code means no mounting bracket is supplied; the GR body is also panel-mountable. As a pure regulator it has no filter bowl and no lubricator - pair it upstream with a filter if the line needs one.
This is a genuine AirTAC part. The GR family spans four sizes (200, 300, 400, 600) with ports from 1/8 to 1 inch, in PT as standard and G or NPT as order options, with round or square gauges in MPa, psi or bar scales, an optional low-pressure type limited to 0.4 MPa, an optional reverse/check valve, and bracket or no-bracket variants. GR units work from -20 to 70 C, wider than the rest of the G family. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application before ordering.

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.

Settling a steady reduced pressure at the take-off point where a 1/2 inch drop feeds machines from the main compressed-air ring, so downstream tools see a constant setting instead of header swings.
Dialling in the working pressure on air-operated clamps, presses and holding fixtures, with the fitted square MPa gauge letting operators read and lock the set point at the regulator.
Regulating supply pressure to cylinders and air cylinders on filling, sealing and conveyor stations, where a stable setting keeps stroke speed and clamping force repeatable across shifts.
Pick the size by the port and flow step: 200 for 1/8-1/4 inch lines, 300 for 3/8-1/2 inch, 400 for 1/2-3/4 inch, 600 for 1 inch. This unit is the 400 size with NPT1/2 ports - step up or down if your line differs. Choose the gauge scale to suit the crew: MPa, psi or bar, in an embedded square gauge (as fitted here) or an optional external round gauge. Thread is PT as standard; G and NPT are catalogue options ordered by code, as with this T variant. Decide on bracket (default) or no bracket (J), and whether you need the low-pressure type (L, up to 0.4 MPa) or the reverse/check valve (K). We do not quote a single rated flow number because the catalogue publishes flow as curves only - send us your line pressure and demand 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 regulator flow as curves, not as a single rated figure, so we do not quote a l/min, m3/h or SCFM number. Tell us your inlet pressure, set pressure and demand and we will confirm the flow from the GR400 datasheet on request before you order.
F is the square gauge option and 1 is the MPa scale, so this unit ships with an embedded square gauge reading in MPa. The catalogue also offers an external round gauge and psi (scale 2) or bar (scale 3) scales - just order the matching code variant.
