The AirTAC GR200-08T AirTAC Air Pressure Regulator NPT1/4 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 PT1/4" 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 GR200-08T is an AirTAC GR-series air pressure regulator: it does one job, holding downstream pressure steady at your set point as upstream supply and plant demand fluctuate. This 200-size unit is ordered with an NPT1/4 (1/4 in) port, a standard regulation range of 0.05-0.9 MPa (7-130 psi), and a round pressure gauge on a psi scale so operators can read and adjust the set point directly. It carries no filter, no bowl and no drain - it is regulation only, so pair it with a GF filter if the line also needs water and particulate removal.
This is a genuine AirTAC part. The GR family spans 200/300/400/600 sizes with ports from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, plus choices of gauge scale, low-pressure type, reverse/check valve and bracket. Rated flow is published as curves rather than a single figure, so ask us and we will confirm the datasheet figures for your application 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.

| (blank) | Standard type — 0.05 - 0.9 MPa (7 - 130 psi). Blank is standard, L is the low-pressure type. |

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.

On a small assembly press or workholding clamp station, this regulator holds the cylinder pressure at the set point so clamping force stays repeatable, with the psi gauge letting the setter dial in and verify the value.
On cartoning or case-packing machines with short-stroke air cylinders, a 1/4 in regulated branch keeps actuator speed and gentle-product handling consistent even as the main header pressure moves.
On a bench test rig or laboratory air drop feeding instruments and small actuators, the regulator gives a stable, operator-adjustable supply pressure with a clear psi readout, backed by the wide -20 to 70 C operating range.
Size the GR by port and flow: the 200 size with its 1/4 in NPT port suits compact circuits and branch lines, while 300/400/600 sizes step up in port and capacity for higher-demand headers. Set the gauge scale to match your team - MPa, psi or bar - this unit ships with the round psi gauge. Choose the NPT thread here if your fittings are NPT; PT is the catalogue standard and G (BSPP) is also available to order. A bracket (or panel mounting) is optional, and a reverse/check valve can be specified if you need the outlet held on supply loss.
One honest note on sizing: AirTAC publishes regulator flow as curves, not a single rated number, so we do not quote a flow figure here. Tell us your line pressure, set point and expected air demand, and we will confirm from the datasheet that the GR200-08T is the right size 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 performance as flow curves rather than a single rated figure, so we do not state a flow number here. Send us your inlet pressure, set point and air demand, and we will confirm the datasheet curve and correct sizing for your application on request.
The C2 code on this model specifies the optional external round gauge on a psi scale, fitted so the set point can be read and adjusted directly. The GR series also offers an embedded square gauge and MPa or bar scales as alternatives - just order the matching code variant.
