The AirTAC GR60025LJF2T 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 GR60025LJF2T is an AirTAC GR-series air pressure regulator: it does one job - holding a stable downstream pressure - and nothing else. This is the 600 size with a 1 in NPT thread, built as the low-pressure (L) type, so it regulates up to 0.4 MPa for circuits that must never see full line pressure. It accepts a maximum inlet pressure of 1.0 MPa (145 psi), works from -20 to 70 C (GR carries the widest temperature window in the G family), and ships with an embedded square gauge reading in psi; an external round gauge is optional. No bracket is fitted, and the GR body is also panel-mountable.
This is a genuine AirTAC part. The GR line spans sizes 200 through 600 with port sizes from 1/8 in to 1 in, in PT (standard), G or NPT thread, with standard or low-pressure regulation, gauge scale choices, and an optional reverse/check valve (K). Flow for this series is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures against 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. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. 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.

Pneumatic hold-down clamps on a carton-sealing line need a gentle, repeatable holding force. This low-pressure regulator lets the line set a capped downstream pressure so delicate packs are gripped without crushing, while the 1 in port feeds a high-demand clamp manifold.
Weft-clearing air jets on a weaving machine work best at a modest, steady pressure. Mounted in the loom's air preparation line, the GR60025LJF2T holds that setpoint across a shift, and the -20 to 70 C rating suits unheated mill air halls.
Laboratory glassware-drying and purge cabinets need low-pressure air that will not disturb samples. This unit steps the building's 1 in shop-air drop down to a safe low setting, with the psi square gauge giving operators a direct local readout.
Start with the port step: the 600 size takes a 1 in connection, so match it to the largest pipe in the circuit and let the flow curves - not a single number - decide whether one unit carries your demand; we will check the curves with you on request. Because this is the L (low-pressure) type, its regulation ceiling is 0.4 MPa: correct for sensitive low-pressure actuators, wrong if you need to set higher. Choose the gauge scale that suits your team - this unit carries the square gauge in psi, and MPa or bar scales exist in the range. Thread is NPT here; PT is the catalogue standard and G is also orderable. Bracket J means no mounting bracket is fitted - add one if the unit will not 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-series flow as curves, not as a single rated figure, so we do not quote a l/min or SCFM number here. Tell us your line pressure, set pressure and demand, and we will confirm the datasheet curve figures for this 600-size, 1 in unit against your application before you order.
The L in the code means the regulator's adjustment range tops out at 0.4 MPa, which suits circuits that must be held at low pressure. It still tolerates up to 1.0 MPa (145 psi) at the inlet, so it can sit directly on a full-pressure main and protect the downstream side. If your setpoint must go above 0.4 MPa, choose a standard GR type instead.
