The AirTAC GR60025LJF2 AirTAC Regulator PT1 1 in Low-Pressure Type 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 GR60025LJF2 is an AirTAC GR-series air pressure regulator for compressed air, built on the size-600 body with a 1 in PT port. This is the low-pressure type, holding downstream pressure anywhere up to 0.4 MPa, and it is supplied with the embedded square gauge scaled in psi. Maximum inlet pressure is 1.0 MPa (145 psi) and the unit operates from -20 to 70 C. No mounting bracket is fitted; the GR body is also panel-mountable.
This is a genuine AirTAC part. The GR family spans sizes 200 to 600 with ports from 1/8 to 1 in, in standard and low-pressure types, with G (BSPP) or NPT thread options to order and a bracket available where wall mounting suits better. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application.

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. |

| 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.

Set a gentle, stable supply pressure for air knives and blow-off nozzles that clear dust and droplets from cartons and trays before labelling, without overdriving the nozzles.
Hold the low, steady jet pressure that air-jet weaving machines need for consistent weft insertion, trimmed at the loom supply rather than at the main header.
Feed positioners and pilot-operated actuators on plant valves from a dedicated low-pressure branch, keeping the pilot circuit isolated from swings on the main air line.
Choose the size by the port and flow step: size 600 carries the 1 in PT connection here, and larger sizes move more air - we can confirm the flow curve against your demand before you order. Pick the regulator type to match the circuit: this L-code unit is the low-pressure type, adjustable up to 0.4 MPa, while the standard GR covers 0.05-0.9 MPa. The gauge is the embedded square type scaled in psi; MPa or bar scales and an external round gauge are the other catalogue choices. Thread is PT as standard, with G (BSPP) and NPT as order options, and a bracket can be specified if panel mounting does not suit. Because flow is published as curves, not a single rating, ask us to confirm sizing against the 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 GR flow as curves, not a single rated figure, so we do not quote a number here. Tell us your line size and demand and we will confirm the flow curve and sizing from the datasheet on request.
It marks the low-pressure regulator type: output is adjustable up to 0.4 MPa. If your circuit needs the full 0.05-0.9 MPa range, order the standard GR600-25 variant instead; the rest of the decode stays the same.
