The AirTAC GR60025JC1TK AirTAC Air Regulator 1 in NPT, MPa Gauge 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" 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 GR60025JC1TK is an AirTAC GR-series air pressure regulator in the largest 600 size, built for compressed air only. It does one job: holding a stable downstream pressure that you set anywhere in the 0.05-0.9 MPa (7-130 psi) range, with a maximum inlet pressure of 1.0 MPa (145 psi). This configuration carries a 1 in NPT port for high-capacity supply lines, an external round pressure gauge scaled in MPa so the setpoint is readable at a glance, and a built-in reverse (check) valve that lets downstream air pass back through the regulator when the upstream supply is removed. No bracket is included in this version, and as a GR unit it has no filter element, no bowl and no drain - it is purely a regulator.
This is a genuine AirTAC part from the GR range, which spans the 200, 300, 400 and 600 sizes with port options from 1/8 in up to 1 in and PT, G or NPT threads. GR regulators operate from -20 to 70 C, wider than the rest of the G-series family, and can also be panel-mounted. We do not publish a single rated flow figure because AirTAC publishes flow as curves - ask us and we will confirm the datasheet figures for your application.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.

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.

Dropping a 1 in plant air header down to a controlled working pressure before it branches to production departments, with the round MPa gauge giving operators a clear local setpoint reading.
Feeding the pneumatic tool circuits, clamps and air blast on a machining centre from a large-diameter drop line, holding steady regulated pressure so clamping force stays repeatable across shifts.
Regulating the supply to pneumatic pushers, stops and diverters on a high-throughput bottling or canning conveyor, where the check valve keeps downstream actuators pressurised during brief supply interruptions.
Start with the size and port: the 600 frame with its 1 in port suits the largest supply lines in the GR range, and the right step is the one whose flow curve covers your air demand with margin - we can check the curve against your consumption before you order. Set your working pressure against the 0.05-0.9 MPa (7-130 psi) adjustment range; if your circuit needs only low regulated pressures, ask about the GR low-pressure type instead. This unit comes with a round gauge on an MPa scale, and psi or bar scales are available if your team reads in those units. The T in the code fixes the thread as NPT; PT is the catalogue standard and G (BSPP) is also orderable, so pick the thread that matches your piping. The fitted reverse (check) valve is worth keeping if downstream cylinders or tanks must not be starved when supply is dropped; specify without it if you want free venting behaviour. Finally, note this version ships without a mounting bracket - order the bracket variant if you want the unit secured to a wall or machine frame, or use the GR's panel-mount capability.
Quick checklist
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 publishes regulator flow as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number for this unit. Tell us your line pressure, set pressure and air consumption, and we will confirm the flow figures from the datasheet curves to check the 600 size and its 1 in NPT port suit your application before you order.
The K is the reverse (check) valve option. It allows air to flow backwards through the regulator from the downstream side, so cylinders, tanks or actuators fed by this unit stay supplied if the upstream pressure drops or the supply is shut off. This GR60025JC1TK has the check valve fitted; if you would rather have unrestricted venting behaviour, order the equivalent GR600 code without the K.
