AirTAC GR200-08 Pressure Regulator (GR20008C4)
The AirTAC AirTAC GR200-08 Pressure Regulator (GR20008C4) 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 (GR20008C4)
GR200-08C4 is an AirTAC G-series air pressure regulator: its single job is holding a steady downstream pressure off your compressed-air supply. There is no filter, no drain bowl and no lubricator in this unit, so it should be fed by filtered air upstream. This configuration is the size 200 body with PT1/4 ports, the standard regulating type, and a round external pressure gauge reading in kgf/cm2. The regulating range is 0.05-0.9 MPa (7-130 psi) against a maximum inlet pressure of 1.0 MPa (145 psi), the working temperature is -20 to 70 C, and a mounting bracket is included.
This is a genuine AirTAC part. The G-series regulator range runs from size 200 to size 600 with ports from 1/8 in up to 1 in, G (BSPP) and NPT threads as order options, gauge scales in MPa, psi or bar as alternatives to this kgf/cm2 dial, a low-pressure L type, and an optional reverse (check) valve. AirTAC publishes flow as performance curves rather than a single rating, so ask us to confirm sizing or request the datasheet for your operating point.

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.

Where the AirTAC GR200-08 Pressure Regulator (GR20008C4) Is Used
Plant air take-off point
Give a production cell its own set working pressure at the take-off from the plant ring main, instead of letting every machine ride on fluctuating header pressure.
Pneumatic valve manifold supply
Feed a solenoid-valve manifold on an automated station at a fixed, repeatable pressure so valve and cylinder behaviour stays predictable shift after shift.
Air tool bench outlet
Regulate the bench outlet where impact drivers and ratchets are connected, keeping tool pressure where the maintenance team has set it on the kgf/cm2 dial.
Is the AirTAC GR200-08 Pressure Regulator (GR20008C4) the Right Regulator?
Size 200 with 1/4 in ports suits compact drops and small actuator groups; when demand outgrows the GR200 flow curve, move up to GR300-10 or GR400-15. The main decodable choice on this code is the gauge: you get a round external dial in kgf/cm2, and the same body can be ordered with MPa, psi or bar scales, or a square embedded gauge, to match the rest of your plant. No check valve is fitted on this version. PT thread is the standard here, with G (BSPP) and NPT as catalogue options, and a mounting bracket is included.
Flow is published as curves, not one rated figure, so share your flow and pressure targets with us and we will confirm sizing against the datasheet before you order.
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 (GR20008C4) FAQ
AirTAC does not publish a single rated flow figure for this regulator - performance is given as flow curves across pressures. Tell us your required flow and the inlet and outlet pressures you are working with, and we will confirm the correct size and operating point from the datasheet before you order.
The 4 in the gauge position C4 selects the kgf/cm2 scale on the round external gauge; C1, C2 and C3 give MPa, psi and bar respectively, and F codes select the square embedded gauge instead. Order the suffix that matches how your team reads pressure - it is a straightforward catalogue choice on the same size 200, PT1/4 regulator.
