The AirTAC GR20008F2T 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 GR20008F2T is an AirTAC GR-series air pressure regulator: its single job is to hold a steady, adjustable downstream pressure from a compressed-air supply. This 200-size unit is specified with 1/4 in NPT ports, the standard regulator type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and an embedded square pressure gauge scaled in psi so operators can set and read the working pressure at a glance. An external round gauge is optional if you prefer a panel-readable dial. The maximum working (inlet) pressure is 1.0 MPa (145 psi), and the unit operates from -20 to 70 C - the GR family carries the widest temperature range in the G series. As a regulator it has no filter bowl and no lubricator; it is purely a pressure-control component.
This is a genuine AirTAC part. The GR family is published in 200, 300, 400 and 600 sizes with port sizes stepping from 1/8 in up to 1 in, with G (BSPP), NPT or PT thread options, a low-pressure type variant, gauge scale choices and an optional reverse/check valve. Flow for this model is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures against 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.

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 bench pneumatic press or clamping fixture, the GR20008F2T sits downstream of the main shutoff to hold the cylinder supply at the pressure the tooling was set up for, with the square psi gauge letting the operator verify the setting at a glance.
On a carton-sealing or case-packing machine with air cylinders and grippers, this regulator keeps the actuator supply steady so seal pressure and gripper force stay repeatable through the shift, even as the plant header pressure wanders.
At an assembly station running air screwdrivers, riveters or blow-off nozzles, the GR20008F2T sets a safe, consistent tool pressure from the 1/4 in drop line, protecting tools and operators from over-pressure at the point of use.
Start with the port and size step: GR200 carries 1/4 in ports, and stepping up to GR300/400/600 gives larger ports and more flow capacity - match the step to the air demand of the circuit rather than to the pipe alone. Next, choose the gauge: this unit ships with the embedded square gauge in psi (scale 2); MPa or bar scales and an external round gauge are order options. Thread is a real choice too: PT is the catalogue standard, while G (BSPP) and NPT are ordered as suffix options - this code's T suffix selects NPT. A mounting bracket is included with this model, and GR is also panel-mountable; the J suffix removes the bracket if you do not want it. Note that GR has no drain, no filter grade and no bowl - if you need water and particulate removal as well, look at the GFR filter-regulator instead. Finally, be honest about sizing: AirTAC publishes GR flow as curves, not a single rated number, so send us your flow and pressure requirements and we will confirm the correct size from 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 rather than a single rated figure, so there is no one rated flow number we can honestly quote. We will confirm the datasheet flow curves for this 200-size, 1/4 in NPT unit against your application's demand before you order - just ask.
F2 decodes as the square gauge fitted, scaled in psi (scales are 1 = MPa, 2 = psi, 3 = bar); an external round gauge is available as an option. The trailing T selects NPT thread - PT is the catalogue standard and G (BSPP) is also an order option. All of these are specification choices made in the model code, not delivery promises.
