AirTAC GR200-08 Pressure Regulator (GR20008C1)
The AirTAC AirTAC GR200-08 Pressure Regulator (GR20008C1) 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.

About the AirTAC GR200-08 Pressure Regulator (GR20008C1)
The GR20008C1 is an AirTAC GR-series air pressure regulator: it does one job, holding a stable downstream pressure from a compressed-air supply, and it carries no filter element, no bowl and no drain. This unit is the 200 size with a PT1/4 (1/4 in) port in PT thread, the standard regulator type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and it is fitted with a round gauge scaled in MPa. Maximum 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. A mounting bracket is included, and the GR is also panel-mountable.
This is a genuine AirTAC part. The GR200 series is the smallest step in the GR line, with larger sizes (300/400/600) offering bigger ports for higher air demand; gauge style and scale, thread (PT standard, G and NPT to order), a low-pressure type and a reverse/check valve are among the decodable options. Because flow is published as curves rather than a single rated figure, 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.
Size Class

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.

Where the AirTAC GR200-08 Pressure Regulator (GR20008C1) Is Used
Pneumatic press station supply
On a bench-mounted pneumatic press, the GR20008C1 sits after the shut-off valve and sets the working pressure the press cylinder actually sees, so operators can dial in the force the job needs and keep it stable through the shift.
Packaging machine actuator circuit
On a carton-sealing or labelling machine with a mix of small cylinders and air-driven actuators, this regulator feeds the 1/4 in drop lines from the main header, giving each station its own set pressure instead of sharing whatever the compressor delivers.
Test rig and lab air bench
On a laboratory air bench where components are exercised at defined pressures, the -20 to 70 C range and the fitted MPa-scaled round gauge let technicians set and read the supply pressure directly at the point of use.
Is the AirTAC GR200-08 Pressure Regulator (GR20008C1) the Right Regulator?
Start with the port step: the GR200 takes a 1/4 in port, and if your line needs more air you step up to GR300/400/600 rather than pushing one unit past its comfort zone - the pressure setting itself (0.05-0.9 MPa here) is independent of that choice. Then pick the gauge: this code carries a round gauge on an MPa scale, and psi or bar scales are available if your team reads in those units. Thread is PT as standard; G (BSPP) and NPT are catalogue options to order. A low-pressure type (L) is available when the setting must stay at or below 0.4 MPa, and a reverse/check valve (K) can be fitted if you need the downstream circuit held on supply loss.
One honest note before you order: AirTAC publishes regulator flow as curves, not as a single rated number, so we cannot quote you a rated flow figure. Tell us your application and we will confirm sizing against the datasheet before you commit.
Quick checklist
- ✓ Body size for your peak flow (PT1/4" here)
- ✓ Standard 0.9 MPa or low-pressure 0.4 MPa
- ✓ Gauge fitted, or order N without
- ✓ Gauge shape C round / F square
- ✓ Scale MPa (1), psi (2) or bar (3)
- ✓ Reflux valve needed, order K
Installation & Maintenance Notes
- check Install downstream of the filter, following the airflow arrow.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Set pressure while air is flowing, then lock the knob.
- check Adjust within 0.05 - 0.9 MPa (7 - 130 psi) only.
- check Operating range -20 to +70 °C.
- check Panel-mount or use the fixing bracket; do not hang it on tubing.
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 GR200-08 Pressure Regulator (GR20008C1) FAQ
AirTAC publishes GR-series flow as performance curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number for this unit. Send us your application details and we will confirm the flow figures from the datasheet so you can size it correctly before ordering.
On GR models the trailing characters describe the gauge: C means a round (external) gauge is fitted, and the scale digit 1 means it reads in MPa. Other scale options (psi or bar) and the standard embedded square gauge are available on related codes, and a code ending in N would mean no gauge at all.
