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 AirTAC GR200-08 is a genuine AirTAC air pressure regulator in the 200 size, fitted with a 1/4 in NPT port (NPT thread, with PT as the standard catalogue thread and G/NPT available as order options). This configuration is the standard regulator type with an adjustment range of 0.05-0.9 MPa (7-130 psi), a maximum inlet pressure of 1.0 MPa (145 psi), and an operating temperature of -20 to 70 C - the widest temperature span in the G series. An external round gauge scaled in MPa is included so downstream pressure can be read at a glance, and the unit is supplied without a mounting bracket; the GR body is also panel-mountable.
As a pure regulator, the GR200-08 does one job: holding a stable, adjustable downstream pressure from your compressed-air supply. The GR range spans the 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, plus a low-pressure type (L), a reverse/check valve option (K), and gauge scale choices of MPa, psi or bar. Because AirTAC publishes flow for this series 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.

| 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. |

| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |

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 and hold the downstream pressure feeding clamping cylinders on a machining or welding fixture, so clamping force stays consistent across every cycle without the operator re-adjusting between jobs.
Regulate the air feeding seal bars, pushers and diverters on a packaging line, keeping each actuator branch at its set pressure independently of swings in the shop-air header.
Feed a robotic end-effector's gripper circuit through the regulator so delicate parts are handled at a set pressure, with the round MPa gauge giving a clear local readout at the cell.
Start with the port step: the 200 size here carries a 1/4 in port, and stepping up to GR300, GR400 or GR600 gives 3/8 in through 1 in - the right step depends on the flow your line needs, so have us check the published flow curves against your demand before ordering. Then settle the decodable options: gauge scale (MPa, psi or bar, with this unit supplied as a round MPa gauge), thread (PT is standard; G and NPT are order options, and this unit is NPT), bracket (J means no bracket; the GR is also panel-mountable), the low-pressure L type where the circuit stays at or below 0.4 MPa, and the K reverse/check valve where backflow protection is wanted. Flow for the GR series is published as curves, not a single rating - ask us to confirm sizing against your application 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 flow for the GR series as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the datasheet and flow curves against your required flow before you order.
PT is the standard catalogue thread for the GR200; G (BSPP) and NPT are order options, and this particular unit is supplied with the NPT 1/4 in port. The round gauge fitted here is scaled in MPa, and psi or bar scales can be selected when ordering.
