The AirTAC GR20008JF1T 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 GR20008JF1T is an AirTAC GR-series air pressure regulator: it does one job, holding a steady downstream pressure from a compressed-air supply that varies upstream. This 200-size unit has 1/4 in NPT 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 F1 suffix means an embedded square gauge with an MPa scale is fitted, so the set pressure is visible at the unit. The J suffix means no mounting bracket is supplied, though the GR body is also panel-mountable. As a regulator it has no filter, no bowl and no drain, and it suits ambient temperatures from -20 to 70 C - a wider window than the rest of the G family.
This is a genuine AirTAC part. The GR range spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, optional low-pressure (L) variants, reverse/check valve (K) builds, gauge scale choices and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and flow figures for your application 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.

Set a stable downstream pressure feeding pneumatic clamps on a machining fixture, so workholding force stays consistent even as the shop air supply fluctuates.
Regulate the air supplied to pick-and-place and pusher cylinders on a packaging conveyor, keeping stroke behaviour repeatable at the pressure the machine was set up for.
Feed hand-held air tools at an assembly bench from a fixed, readable set pressure, protecting tools and operators from over-pressure on a shared shop-air drop.
Size drives the port and the flow capacity: this GR200 is the compact end of the range with 1/4 in NPT ports, and the GR300, GR400 and GR600 steps take larger ports when the line demands more air. The regulation range for this standard type is 0.05-0.9 MPa (7-130 psi); if your setpoint sits at the low end, the L-suffix low-pressure variant covers up to 0.4 MPa. On the gauge, the embedded square gauge is standard here with an MPa scale, and an external round gauge with MPa, psi or bar scales is optional. On thread, PT is the AirTAC standard, while G (BSPP) and T (NPT) are catalogue options - this unit is ordered as NPT. J means no bracket is included. 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 flow as curves rather than a single rated figure, so there is no one flow number we can honestly quote. We can confirm the flow figures from the datasheet for your specific conditions on request - just tell us your inlet pressure and set pressure and we will check the sizing with you before you order.
F means an embedded square gauge is fitted and 1 means it is scaled in MPa, which is what this unit carries. If you prefer a different readout, the GR range also offers an external round gauge, and gauge scales in MPa (1), psi (2) or bar (3) can be specified in the code when ordering.
