The AirTAC GR60025JC2K AirTAC Air Pressure Regulator PT1 in 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 GR60025JC2K is an AirTAC GR-series air pressure regulator for compressed air, built in the largest GR600 size with a 1 in PT port. It does one job only: holding a stable downstream pressure. The standard-type regulation range is 0.05-0.9 MPa (7-130 psi) against a maximum inlet pressure of 1.0 MPa (145 psi), and this configuration is ordered with an external round pressure gauge scaled in psi. A built-in reverse (check) valve lets downstream air pass back upstream when the supply is removed, and the unit is supplied without a mounting bracket - GR regulators can also be panel-mounted.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, in PT as standard and G (BSPP) or NPT as order options, with gauge scale choices of MPa, psi or bar, a low-pressure type (up to 0.4 MPa) and bracket or no-bracket variants. Flow for this regulator is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

|---|---|
| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| (blank) | Standard type — 0.05 - 0.9 MPa (7 - 130 psi). Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |

| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 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.
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 a steady downstream pressure feeding a bank of directional control valves on a large press or forming line, so valve shifting behaviour stays consistent across the shift.
Drop the header pressure to the level a production cell actually needs at a 1 in main air drop, protecting downstream equipment from supply-side pressure swings.
Hold the clamping pressure on pneumatic workholding fixtures and jigs on a machining line, with the check valve helping hold the set circuit when the air supply is shut off.
Start with the size and port: GR600 is the largest step in the GR range, with a 1 in PT port, so match it to the pipe diameter and the flow your line needs. Decide the gauge you want - this code carries an external round gauge scaled in psi; MPa and bar scales are also available. Choose the thread: PT is the standard for this code, with G (BSPP) and NPT as catalogue options to order. This unit is ordered without a mounting bracket (J code), though GR regulators are also panel-mountable, and the K code means a reverse/check valve is fitted. A low-pressure type (L code, up to 0.4 MPa) exists if your setpoint sits low. One honest note on sizing: flow is published as curves, not a single rated number, so send us your application details and we will confirm the right size against the datasheet before you order.
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, not as a single rated figure, so we do not quote a flow number for this unit. Send us your line pressure, set pressure and expected air demand and we will confirm the sizing against the datasheet on request.
K means a reverse (check) valve is fitted, allowing downstream air to flow back upstream when the supply is removed. The C2 in the code means an external round pressure gauge scaled in psi is included; MPa and bar gauge scales are available as other order options.
