The AirTAC GR60025LJC2 AirTAC Low-Pressure Regulator PT1 in 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 GR60025LJC2 is an AirTAC GR-series air pressure regulator: it does one job, holding a stable downstream pressure from your compressed-air supply, and it does nothing else - no filtration, no bowl, no lubrication. This 600-size unit is decoded as a low-pressure type (L) with a 1 in PT female port, a setting range up to 0.4 MPa, a round external gauge with a psi scale (C2), and no mounting bracket (J), so it mounts directly in the line or to a panel as your install requires. It is a genuine AirTAC part for compressed air only, rated for a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -20 to 70 C - a wider temperature window than the rest of the G-series families.
The GR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, in standard and low-pressure types, with or without a bracket, and with embedded square or external round gauges in MPa, psi or bar scales. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application 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.

| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| L | Low-pressure type — 0.05 - 0.4 MPa (7 - 58 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) | No reverse-flow valve (the default). |
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.

On a carton-sealing and case-erector line running at modest set pressures, this 1 in low-pressure regulator holds a steady downstream pressure to the header feeding the cylinders and blow-off points, with the psi gauge letting operators check the setting at a glance.
Air-jet weaving needs a consistent low-pressure air supply to the main nozzle header. This regulator, fitted in the 1 in PT supply line ahead of the loom, lets the maintenance team set and hold the working pressure the process calls for.
In a pellet or powder transfer loop that runs its motive air at low set pressure, this 600-size regulator sits in the 1 in PT branch feeding the conveying valve manifold, keeping the line pressure stable as batches change.
Start with the port and flow path: this is the 600 size with a 1 in PT port, the largest step in the GR range, so match it to your line diameter and required air demand. Because this is the L (low-pressure) type, its setting range tops out at 0.4 MPa - choose it when your process runs at low set pressures, and choose the standard GR type instead if you need the full 0.05-0.9 MPa range. The C2 code gives you an external round gauge reading in psi; if your team works in MPa or bar, a different gauge scale is available in the family. Thread is PT as standard, with G (BSPP) and NPT available as order options, and the J code means no bracket is fitted - add a bracket variant if you want panel or surface mounting. Flow in this series is published as curves, not a single rating, so send us your application details 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-series flow as curves rather than a single rated number, so we do not quote a rated flow, Cv or SCFM figure for this unit. Tell us your line size, inlet pressure and set pressure, and we will confirm the sizing against the datasheet on request before you order.
L marks the low-pressure type of the GR family. Its setting range tops out at 0.4 MPa, instead of the wider range of the standard GR type, so it suits processes that run at low set pressures. Everything else decodes as the 600 size, 1 in PT port, round external gauge with a psi scale, and no mounting bracket.
