The AirTAC GR60025LC2G AirTAC Air Pressure Regulator G1 Low-Pressure is a genuine G-series air pressure regulator. It holds a stable downstream pressure over the range 0.05 - 0.4 MPa (7 - 58 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 GR60025LC2G is an AirTAC GR-series air pressure regulator in the largest GR600 size, built for one job only: holding a steady downstream air pressure. This is the low-pressure (L) type, so it regulates in the range up to 0.4 MPa, and it carries a round pressure gauge reading in psi so the setpoint can be checked at a glance. The G1 (1 in) G-thread port suits large-bore supply lines, and the unit is supplied with a mounting bracket; GR regulators are also panel-mountable. Because it is a regulator, it has no filter bowl and no drain - pair it with a GF filter upstream if the line needs water and particulate removal.
This is a genuine AirTAC part. The GR family spans sizes 200 through 600 with port sizes from 1/8 in to 1 in, standard or low-pressure regulation, gauge or no-gauge builds, MPa/psi/bar gauge scales, PT/G/NPT thread options, and a reverse/check valve option. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet 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.

| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 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.

Bottling and cartoning lines often run pneumatic clamps and hold-downs at reduced pressure to avoid crushing lightweight packs. This low-pressure GR600 regulator holds the setpoint on a 1 in supply header feeding those clamp cylinders.
Paint, adhesive and powder systems need a stable, reduced air supply to their atomizing and low-pressure conveying stations. This regulator sits on the branch line and keeps that supply steady regardless of header swings.
Dancer rolls, thread guides and low-pressure actuator banks on wide web machines need gentle, consistent air. The GR60025LC2G regulates the branch feeding those devices, with the psi gauge letting operators verify the setting during changeover.
Start with the port and flow path: this unit is the 600 size with a G1 (1 in) thread, the largest step in the GR range - match it to the line size and the air demand of the circuit, and step down to GR200/300/400 where flow is smaller. The L code makes this the low-pressure type regulating up to 0.4 MPa; if your circuit needs up to 0.9 MPa, choose a standard GR build instead. Gauge choices are embedded square (standard) or external round, with MPa, psi or bar scales - this build has a round psi gauge. Thread is PT as standard with G and NPT as order options; a J code removes the bracket if panel mounting is preferred. Flow is published as curves, not a single rating, so send us your application and we will confirm sizing against the datasheet 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 GR flow as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your inlet pressure and the air demand of your circuit and we will confirm the sizing against the datasheet curves on request before you order.
The L in the code is the low-pressure type: it regulates up to 0.4 MPa, which suits circuits that must never see full line pressure. A standard GR600 (no L code) regulates up to 0.9 MPa. Both share the same 1.0 MPa maximum inlet pressure, and this build also differs in carrying a round psi gauge and the G1 thread option.
