The AirTAC GR20008C2G AirTAC Regulator G1/4 | 0.05-0.9 MPa 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 GR20008C2G is a genuine AirTAC air pressure regulator in the GR200 size, built for one job only: holding a steady, user-set downstream pressure from a compressed-air supply. It carries no filter and no bowl, so there is nothing to drain - regulation is the whole function. This configuration is decodes to a 1/4 in G-thread (BSPP) port, the standard (non low-pressure) regulator type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and an external round pressure gauge on a psi scale so you can read and set the outlet pressure directly. A mounting bracket is included, and the GR body is also panel-mountable. Maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -20 to 70 C (non-freezing) - wider at the low end than the rest of the G-series, which suits colder plant air environments.
This is a genuine AirTAC part. The GR family spans four sizes (200, 300, 400, 600) with stepped port sizes and flow capacity, plus options including G or NPT thread in place of PT, an embedded square gauge or an external round gauge in MPa, psi or bar scales, a low-pressure type limited to 0.4 MPa, a reverse/check valve, and bracketless variants. Because AirTAC publishes regulator flow only as curves rather than a single rated figure, we confirm the flow and datasheet figures for your application on request - just ask 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.

Sets and holds the regulated pressure feeding clamp cylinders on a weld fixture, so clamping force stays consistent from part to part while the round psi gauge lets operators verify the setpoint at a glance.
Regulates the branch line feeding pneumatic pushers and diverters on a packaging conveyor, keeping actuator speed repeatable as the main header pressure wanders during shift start-ups.
Drops plant header pressure to a stable, lower level for panel-mounted pneumatic controls and pilot devices, with the bracket allowing clean mounting beside or inside the enclosure.
Start with the size and port: the GR series steps through sizes 200, 300, 400 and 600, and each size carries a defined port - this unit is size 200 with a 1/4 in port. Match the size step to the air demand of the circuit downstream, then confirm it: flow is published as curves, not a single rating, so ask us to check the curve against your application before ordering. Next, choose the gauge: this code carries an external round gauge on a psi scale; square embedded gauges and MPa or bar scales are the other catalogue options. Choose the thread to suit your piping - PT is the standard, with G (BSPP) and NPT available as order options. The standard type covers 0.05-0.9 MPa (7-130 psi); if your setpoint never exceeds 0.4 MPa, the L low-pressure type exists. A reverse/check valve (K) and a bracketless (J) build are also decodable options. This unit includes the bracket and is panel-mountable as well.
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 regulator flow as performance curves rather than a single rated number, so we do not quote a flow figure for this unit. Send us your application details and we will confirm the flow from the datasheet curve against your air demand before you order.
C2 decodes to an external round gauge fitted on a psi scale (square embedded gauges and MPa or bar scales are the other options). The trailing G is the G (BSPP) thread option on the 1/4 in port; PT is the catalogue standard and NPT is also available to order - all three are specification choices, so pick the one that matches your piping.
