The AirTAC GR200-08 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 GR200-08 is a genuine AirTAC GR-series air pressure regulator in the 200 size with a 1/4 in NPT port. It does one job only: holding a stable downstream pressure that you set anywhere in the 0.05-0.9 MPa (7-130 psi) adjustment range, with a maximum inlet pressure of 1.0 MPa (145 psi). This configuration is the standard type, fitted with an external round gauge reading in bar, and supplied without a mounting bracket - the GR body is also panel-mountable. There is no filter, no bowl and no drain on this unit, so it regulates clean, already-filtered air.
The GR family spans four sizes (200, 300, 400 and 600) with increasing port sizes and flow capacity, and options that include PT, G (BSPP) or NPT threads, a low-pressure type rated to 0.4 MPa, gauge scales in MPa, psi or bar, and a reverse/check valve. GR units operate from -20 to 70 C, wider than the rest of the G-series. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application before ordering.

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 steady, reduced pressure feeding clamping cylinders so parts are held consistently without over-pressurising the fixture, with the bar gauge giving the operator a clear set-point readout.
Regulate the air feeding carton closers, diverters and pusher cylinders on a packaging conveyor, keeping actuation behaviour repeatable as the main header pressure fluctuates through the shift.
Drop header pressure to a controlled level for a dedicated branch feeding air-powered tooling or workholding on a CNC or manual machine, panel-mounted next to the machine's air preparation point.
Size the GR by port and required flow: the 200 series here carries a 1/4 in port, and stepping up to 300, 400 or 600 gives larger ports for higher air demand. Set the working pressure anywhere in the 0.05-0.9 MPa (7-130 psi) range; if your line runs below that, the GR low-pressure type (L) covers settings up to 0.4 MPa. Choose the gauge to match your shop floor: this unit has a round gauge in bar, while MPa and psi scales and an embedded square gauge are available. Thread is NPT on this code; PT is the catalogue standard and G (BSPP) can be ordered. A bracket can be added if you do not panel-mount, and a reverse/check valve can be fitted to hold downstream pressure if the supply drops.
One honest note on sizing: AirTAC publishes GR flow as curves, not a single rated figure, so we do not quote a flow number here. Send us your application details and we will confirm the datasheet curve against your demand 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 curves rather than a single rated figure, so we do not quote a flow number for this unit. Tell us your port size, inlet pressure and the air demand of your application, and we will confirm the datasheet flow curve for the GR200-08 on request before you order.
The C in the code GR20008JC3T specifies an external round gauge, and the 3 sets its scale to bar. Gauge options across the GR series include an embedded square gauge and scales in MPa, psi or bar, so you can order the combination that matches the instruments already on your line.
