The AirTAC GR60025LJC1T AirTAC Low-Pressure Air Regulator NPT1 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 GR60025LJC1T is an AirTAC GR600 low-pressure air pressure regulator: it does one job, holding a stable downstream air pressure, and it does nothing else - no filter, no bowl, no drain and no lubrication. This 600-size unit carries a 1 in NPT port, is set up for NPT piping, and is the L low-pressure type, so its setpoint range tops out at 0.4 MPa. A round pressure gauge scaled in MPa is fitted so the setpoint can be read directly, and the J suffix means no mounting bracket is included - the GR600 can also be panel-mounted. Maximum working (inlet) pressure is 1.0 MPa (145 psi), and the operating temperature range is -20 to 70 C, wider than the rest of the G-series families.
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, and is ordered with your choice of thread (PT as standard, G and NPT as options), gauge type and scale (MPa, psi or bar), a low-pressure variant, and bracket or no bracket. Flow for this family 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.

|---|---|
| 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. |
| 1 | Gauge scale: MPa. 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 carton-sealing or case-erecting machine, low-pressure air drives light clamping and hold-down cylinders. This regulator lets a technician set and read a gentle, stable supply pressure so delicate cartons are held without crushing.
Loom and spinning machines use low-pressure air jets for threading and cleaning. A 1 in low-pressure regulator at the machine inlet lets maintenance set the jet pressure once and keep it steady shift after shift.
Air-operated diaphragm pumps on chemical transfer skids are throttled by their air supply pressure. This regulator, fitted with an MPa gauge at the pump's 1 in air inlet, gives operators a single point to set and monitor the pump's drive pressure.
Start with the port step: size 600 with a 1 in port is the largest GR frame, so match it to your line size and the flow your circuit needs - and because flow is published as curves, not a single rating, ask us to confirm sizing against the application before ordering. This unit is the L low-pressure type with a setpoint range up to 0.4 MPa; if your process needs up to 0.9 MPa, choose the standard GR type instead. The round gauge fitted here reads in MPa; psi and bar scales are available if your team works in those units. Thread is NPT on this code - PT is the catalogue standard and G (BSPP) is also orderable, so pick the one that matches your piping. Finally, this code ships without a mounting bracket (J); order a bracketed version if you want the unit secured to a wall or manifold plate, or use the GR's panel-mount capability.
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 rated flow, Cv or SCFM number for this unit. Tell us your line size and the flow your application needs, and we will confirm the datasheet curve figures for the GR600 on request before you order.
L marks the low-pressure type of the GR regulator: its setpoint range tops out at 0.4 MPa instead of the standard type's 0.05-0.9 MPa. Choose the L version when your process runs at low setpoints and you want finer control there; choose the standard GR when you need up to 0.9 MPa. Maximum inlet pressure is 1.0 MPa (145 psi) either way.
