The AirTAC GR60025LJC3T AirTAC Air Pressure Regulator NPT1 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 GR60025LJC3T is an AirTAC GR-series air pressure regulator: it does one job, holding a steady downstream pressure from your compressed-air supply, and it carries no filter element, no bowl and no lubricator. This is the size-600 unit with a 1 in NPT port, built as the low-pressure type, so its setting range tops out at 0.4 MPa - the right choice when the downstream equipment must never see full line pressure. A round pressure gauge with a bar scale is fitted so the set point can be read directly, and the maximum inlet pressure is 1.0 MPa (145 psi). Operating temperature is -20 to 70 C, wider than the rest of the G family. No mounting bracket is included with this code; the GR series is also panel-mountable.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, in standard or low-pressure types, with or without a gauge, with MPa, psi or bar scales, with an optional reverse/check valve, and in PT (standard), G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application before you order.

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. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |

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 weaving shed's air-jet looms, the GR60025LJC3T steps a 1 in main down to a stable, capped pressure so the insertion air stays within the low-pressure limit the loom controls expect.
Feeding a wide air-knife blow-off header on a bottle or carton conveyor, the low-pressure type keeps the header pressure safely capped at 0.4 MPa while the 1 in NPT port matches the main drop.
On a woodworking press or fixture clamp circuit that must not exceed a low set point, this regulator holds the clamp pressure steady and the fitted bar-scale gauge lets operators verify the setting at a glance.
Sizing a GR regulator starts with the port step: sizes 200 to 600 cover 1/8 in to 1 in, and the larger the size the more flow the body passes - match the port to your line and let us check the flow curve against your demand. The key decode choice on this code is the low-pressure type (L): its setting range stops at 0.4 MPa, so pick the standard type instead if you need settings up to 0.9 MPa. Gauge options are an embedded square gauge or an external round gauge, with MPa, psi or bar scales - this unit carries a round gauge on a bar scale. Thread is PT as standard, with G and NPT as orderable options; this code is NPT. The J suffix means no mounting bracket, and GR can also be panel-mounted. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 curves, not as a single rated number, so we do not quote a l/min, m3/h or SCFM figure. Tell us your line size and demand and we will confirm the datasheet flow curve for this exact model on request before you order.
The L in GR60025LJC3T marks the low-pressure type, whose setting range tops out at 0.4 MPa - ideal where downstream equipment must never see full line pressure. If you need settings up to 0.9 MPa, choose the standard GR type instead; we can quote the equivalent code.
