The AirTAC GR30015F2T 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 GR30015F2T is an AirTAC GR-series air pressure regulator: it does one job, holding your downstream pressure steady at the set point as upstream supply and air demand fluctuate. This GR300 size is fitted with 1/2 in NPT ports, and the trailing T in the code specifies the NPT thread option (PT is the standard thread; G/BSPP is also available to order). It carries the embedded square pressure gauge with a psi scale, and the trailing code confirms no reverse/check valve is fitted. As a GR unit it contains no filter and no bowl - pair it with a GF filter upstream if the air line needs water and particulate removal.
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, optional low-pressure type (up to 0.4 MPa), a reverse/check valve option, gauge scale choices of MPa, psi or bar, and panel-mount capability as well as the included bracket. Max inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -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 figures for your application.

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 fixed, repeatable downstream pressure for a press or clamp cylinder on a machining cell, so clamping force stays consistent from cycle to cycle even as the compressor loading varies.
Feed the gripper and sealing cylinders on a packaging line from a regulated branch circuit, protecting the actuators from supply swings while the rest of the plant runs at full header pressure.
Drop a 1/2 in plant air main down to a controlled lower pressure for a work zone or machine group, with the psi square gauge giving operators a local readout of the set point.
Start with the port step: GR sizes run 200/300/400/600 with ports from 1/8 in to 1 in, and the right size is the one whose flow curve covers your air demand at acceptable pressure drop - we can check the curve against your consumption if you send the figures. Set your regulation window: this standard GR300 adjusts from 0.05 to 0.9 MPa (7-130 psi); if your set point never exceeds 0.4 MPa, the L low-pressure type exists as an alternative. Choose the gauge scale (MPa, psi or bar) and, if you prefer a panel readout, an external round gauge is available alongside the embedded square gauge. Select the thread - PT is standard, with G and NPT as order options - and note the bracket is included, with panel mounting also possible on GR. 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 curves rather than a single rated figure, so we do not quote a l/min, m3/h or SCFM number. Send us your air demand and upstream pressure and we will confirm the flow from the datasheet curve for this GR300 size before you order.
F is the embedded square gauge, 2 is the psi scale, and T specifies NPT threads (PT is the standard thread; G/BSPP is also an order option). Gauge scales are available in MPa, psi or bar, and an external round gauge can be specified instead - tell us your preference and we will quote the matching code.
