The AirTAC GR60025LJC2T 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 GR60025LJC2T is an AirTAC GR-series air pressure regulator: it does one job, holding downstream compressed-air pressure steady, and it does nothing else - no filter element, no drain bowl and no lubricator. This unit is the 600 size with a 1 in NPT port, built as the low-pressure type with an adjustment range up to 0.4 MPa, which suits circuits that must never see full line pressure. It carries a round pressure gauge scaled in psi, and the J code means no mounting bracket is fitted, though GR bodies are also panel-mountable. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -20 to 70 C, wider than the rest of the G family.
This is a genuine AirTAC part. The GR line spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, in standard or low-pressure versions, with or without a bracket, and with embedded square or external round gauges in MPa, psi or bar scales. Flow figures for this series are published as curves rather than a single rating, so ask us and we will confirm the datasheet figures against 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". |
| 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. |
| 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.

Vacuum and clamp circuits on CNC routers often need a gentle, stable holding pressure well below shop-line pressure. A low-pressure GR set to a safe ceiling keeps workpiece clamps from crushing soft stock or marring finished surfaces.
Paint booths depend on low, steady atomising pressure at the gun. A low-pressure regulator at each booth drop lets the painter lock in the setting, and the psi-scale round gauge reads out in the units the shop already works with.
Blow-off nozzles that dry or clear packaging film run best at modest, repeatable pressure. A 1 in low-pressure regulator on the header feeding the air knives keeps the jet gentle enough for delicate wrappers while staying constant across the shift.
Start with the port and size: the 600 frame with a 1 in connection is the largest GR step, so size it against the air demand of the circuit - and because flow is published as curves, not a single rated number, ask us to confirm the sizing before you order. Choose the low-pressure type (L) only when the downstream equipment needs settings up to 0.4 MPa; the standard GR covers 0.05-0.9 MPa. This unit has a round gauge on a psi scale; square embedded gauges and MPa or bar scales are the other catalogue choices. Thread options are PT as the standard, with G (BSPP) and NPT available to order - this code is the NPT version. Bracket: this configuration omits it (J), and GR can also be panel-mounted.
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 performance curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure and the air demand of the circuit, and we will confirm the datasheet curve figures for this 600-size, 1 in unit on request before you order.
The L in the code marks the low-pressure type, whose adjustment range goes up to 0.4 MPa instead of the standard GR range - use it where downstream equipment must not see full line pressure. The C2 in the code means an external round gauge scaled in psi is fitted, so settings read out directly in psi.
