The AirTAC GR40015F1T 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 GR40015F1T is an AirTAC GR-series air pressure regulator: it does one job, holding a steady downstream pressure from your compressed-air supply. This 400-size unit is decoded with a 1/2 in NPT port, the standard (non-low-pressure) regulator type, an adjustment range of 0.05-0.9 MPa (7-130 psi), and a factory-fitted embedded square gauge reading in MPa. No reverse/check valve is fitted, and the mounting bracket is included, so the unit can be bracket-mounted or panel-mounted in your air-preparation line.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, gauge scales in MPa, psi or bar, optional G (BSPP) or NPT threads instead of the PT standard, and a low-pressure type for applications up to 0.4 MPa. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the GR temperature range is -20 to 70 C. Because flow is published as curves rather than a single rated figure, 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.

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.

Dropping the compressor header pressure to a stable, lower working pressure for a production hall's air ring main, with the square MPa gauge giving operators a local setpoint readout at the 1/2 in takeoff.
Setting and holding the clamping or forming pressure on a machine tool's air cylinders, where the regulator holds the downstream setpoint steady while the press cycles through its stroke.
Trimming supply pressure to individual actuators on a packaging or bottling line - grippers, pushers and diverters - so each station runs at its own tuned pressure from a shared 1/2 in air drop.
Start with the port step: this unit is 400 size with a 1/2 in NPT port, and the GR range steps through 200/300/400/600 with ports from 1/8 in to 1 in, so pick the size whose flow curve covers your demand rather than oversizing on guesswork. The regulation range here is 0.05-0.9 MPa (7-130 psi); if your setpoint stays at or below 0.4 MPa, the GR low-pressure (L) type is the alternative. Choose the gauge scale you want - this code carries the square gauge in MPa, with psi or bar available - and note the thread: PT is the catalogue standard, while G (BSPP) and NPT are options you order explicitly, as decoded here. A bracket is included, and GR can also be panel-mounted.
One honest routing note: AirTAC publishes GR flow as curves, not a single rated number, so send us your line pressure, set pressure and expected air demand and we will confirm the 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 GR regulator flow as performance curves, not as a single rated figure, so we do not quote a Cv, l/min or SCFM number. Send us your inlet pressure, set pressure and expected air consumption, and we will confirm the sizing against the datasheet on request before you order.
F1 decodes as the embedded square gauge with an MPa scale; an external round gauge is optional, and psi or bar scales can be ordered. The thread on this unit is NPT (the trailing T), while PT is the catalogue standard and G (BSPP) is also available as an order option - all stated as specification choices, not delivery promises.
