The AirTAC GR60025LJF2K AirTAC Air Pressure Regulator 1 in PT 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 GR60025LJF2K is an AirTAC GR-series air pressure regulator: it does one job, holding a steady downstream pressure from your compressed-air supply. This is the low-pressure type (code L), so its adjustment range tops out at 0.4 MPa, and it is built in the largest GR600 size with a 1 in PT port. The embedded square gauge is fitted with a psi scale so operators can read and set pressure directly, and the K code means a reverse (check) valve is fitted so downstream pressure is held if the upstream supply drops. The J code means no mounting bracket is supplied; the GR body is also panel-mountable.
This is a genuine AirTAC part. The GR600 line is the largest of the four GR sizes (200/300/400/600), with G (BSPP) and NPT thread versions available to order alongside the standard PT. 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. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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.
| GR600 | G-series pressure regulator, 600 body — sets the port range. |
|---|---|
| 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. |

| K | Reverse-flow (reflux) valve fitted. |
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 machining fixture or jig line running air clamps at low setpoints, this low-pressure GR regulator holds the clamp pressure steady at or below 0.4 MPa, with the fitted check valve holding the clamp if supply pressure drops.
At the 1 in drop from a plant air main feeding a packaging or bottling line, this GR600 regulator gives operators a local psi-gauge setpoint for the whole downstream circuit without adding filtration or lubrication where it is not wanted.
For process or lab equipment that needs a gentle, stable low-pressure air feed, this regulator trims the supply down to the required low setpoint and the psi-scale square gauge lets technicians verify the setting at a glance.
Start with the port step: GR600 with a 1 in PT port suits lines where the main supply is 1 in and you want the regulator to match it without reducers. Choose the low-pressure L type only when your setpoint stays at or below 0.4 MPa; if you need the full 0.05-0.9 MPa range, the standard GR type is the right pick. The embedded square gauge is standard here with a psi scale, and MPa or bar scales plus an external round gauge are the other catalogue options. Thread is PT as standard, with G (BSPP) and NPT as orderable options, and brackets are optional (this code omits one). Flow is published as curves, not a single rated figure, so send us your flow and pressure requirements and we will confirm sizing against the datasheet before you order.
Quick checklist
The reflux valve lets air flow back through the regulator, which is useful when downstream volume must vent quickly. A regulator does not remove water or particulate; that is the filter's job.
AirTAC publishes regulator flow as curves rather than a single rated number, so there is no one figure we can honestly quote. Tell us your upstream pressure, setpoint and required flow, and we will confirm the sizing against the GR600 datasheet on request before you order.
L is the low-pressure type: the adjustment range tops out at 0.4 MPa instead of the standard GR range, which suits circuits with low setpoints. And no - the GR family is regulation only. It has no filter, no bowl and no drain; if you need filtration, look at the GF or GFR families instead.
