The AirTAC GR60025LF3T AirTAC Air Pressure Regulator 1 in NPT 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 GR60025LF3T is an AirTAC GR-series air pressure regulator in the size 600 frame, the largest in the G-series line, fitted with a 1 in NPT port. This is a low-pressure (L) type: its set point can be adjusted up to 0.4 MPa, making it the right choice where the process needs a gentle, stable supply pressure rather than full line pressure. The embedded square gauge reads in bar, so the set point can be checked and adjusted at a glance, and an external round gauge is available as a catalogue option. As a pure regulator it does one job only - holding downstream pressure steady - with no filter element and no bowl to maintain.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, in standard and low-pressure types, with PT as the standard thread and G (BSPP) and NPT available as ordering options. GR units work in compressed air from -20 to 70 C, the widest temperature window in the G-series, mount with the included bracket or panel-mount, and can be ordered with a reverse/check valve where needed. Flow 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. |

| F | Gauge shape: Square. C is round, F is square. |
| 3 | Gauge scale: bar. 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.

On a carton-sealing or wrapping line where delicate pneumatic actuators and glue heads are rated well below full line pressure, this low-pressure regulator holds a gentle, steady set point on a 1 in NPT supply header, with the bar-scale square gauge making the setting easy to verify during changeover.
Wide air knives and jet nozzles on weaving, drying or web-cleaning stations need a modest, even pressure rather than a hard blast. This size 600 regulator on the 1 in NPT branch feed lets operators dial the jet pressure in bar and keep it stable as the header pressure wanders.
In a plant air distribution panel feeding valve manifolds and positioners, this regulator on the 1 in NPT control-air branch holds a low set point for pressure-sensitive pilot circuits, panel-mounted beside the gauges so technicians can read and trim the setting without shutting the line down.
Start with the port and flow path: this unit steps up to the size 600 frame with a 1 in NPT connection, so match it to lines where the pipe run and expected air demand justify the larger port. Because flow is published as curves rather than a single rating, send us your application details and we will confirm sizing against the datasheet before you order. The L code here is decisive: this is the low-pressure type, adjustable up to 0.4 MPa - if your process needs to set above that, the standard GR type is the correct pick instead. The gauge on this code is the embedded square type reading in bar; MPa and psi scales and an external round gauge are the other catalogue choices. Thread is NPT on this code, with PT standard and G (BSPP) as options; the mounting bracket is included, and GR also panel-mounts.
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 performance curves, not as a single rated number, so there is no one figure we can honestly quote. Tell us your upstream pressure, set point and air demand, and we will confirm the sizing from the datasheet curves on request before you order.
L marks the low-pressure type of the GR family: its adjustment range tops out at 0.4 MPa instead of the standard type's range. Everything else about the code decodes as size 600, 1 in NPT thread, embedded square gauge reading in bar, bracket included, and no reverse/check valve fitted.
