AirTAC GR200-08 Pressure Regulator (GR20008JC1K)
The AirTAC AirTAC GR200-08 Pressure Regulator (GR20008JC1K) 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 (GR20008JC1K)
GR20008JC1K is an AirTAC G-series air pressure regulator with a built-in reverse (check) valve, so it regulates downstream pressure while preventing backflow through the unit. It contains no filter and no lubricator - regulation only. The 200 size has a PT1/4 port (1/4 inch PT thread as standard), and this JC1K configuration includes an external round gauge scaled in MPa. Adjustment range is 0.05-0.9 MPa (7-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and operating temperature spans -20 to 70 C.
This is a genuine AirTAC part from the G-series regulator range, available in 200, 300, 400 and 600 sizes with ports from 1/8 to 1 inch and G (BSPP) or NPT thread variants to order. The J in the code means no mounting bracket is included; the bracket version is a catalogue option. Flow for these regulators is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application.

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.
Model Code: AirTAC GR200-08 Pressure Regulator (GR20008JC1K)
| GR200 | G-series pressure regulator, 200 body — sets the port range. |
|---|---|
| 08 | Port size PT1/4". This body offers 06 = PT1/8", 08 = PT1/4". |
| (blank) | Standard type — 0.05 - 0.9 MPa (7 - 130 psi). Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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

- GR400PT3/8" - PT1/2"
- GR600PT3/4" - PT1"
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 (GR20008JC1K) Is Used
Cylinder circuit with intermittent exhaust
Regulate the feed to a double-acting cylinder circuit where the check valve stops downstream air pushing back through the regulator during valve cycling.
Clamp fixture pressure control
Hold a fixed clamping pressure on a machining or welding fixture circuit, with the MPa gauge letting operators verify the setpoint before a cycle.
Manifold branch regulation
Set an isolated branch pressure on a multi-circuit manifold where the K version protects the regulator setting from back-pressure on the shared line.
Is the AirTAC GR200-08 Pressure Regulator (GR20008JC1K) the Right Regulator?
Choose this K variant over the plain JC1 when backflow through the regulator could be a problem in your circuit - the check valve is fitted as part of the unit. The 200 size with PT1/4 port suits 1/4 inch lines; larger sizes (300/400/600) step the port and flow capacity up. The JC1 gauge reads in MPa; C2 and C3 variants give psi or bar scales. No bracket is included with the J code, and PT is the standard thread with G and NPT available to order. Since flow is published as curves, ask us to confirm sizing against your application before ordering.
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.
The reflux valve lets air flow back through the regulator, which is useful when downstream volume must vent quickly. A regulator does not remove water or particulate; that is the filter's job.
AirTAC GR200-08 Pressure Regulator (GR20008JC1K) FAQ
There is no single rated flow number for this regulator - AirTAC publishes performance as flow curves. Ask us for the datasheet and we will confirm the curve data and check it against your application before you order.
The K code means a reverse (check) valve is fitted inside the unit, preventing backflow through the regulator. Everything else in the decode is the same: 200 size, PT1/4 port, round MPa gauge, no bracket, and a 0.05-0.9 MPa adjustment range.
