The AirTAC GR60025LF2GK AirTAC Air Pressure Regulator G1 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 GR60025LF2GK is an AirTAC GR-series air pressure regulator: its single job is to hold a steady downstream pressure from your compressed air supply. This is the 600 size, the largest in the GR range, with a G1 (1 in) female thread. The L in the code marks the low-pressure type, so its adjustment range tops out at 0.4 MPa - the right choice where the process needs fine control at low settings rather than full line pressure. The F2 code gives you the embedded square gauge reading in psi, and the K code means a reverse (check) valve is fitted so downstream pressure is held if the upstream supply drops. A mounting bracket is included, and GR bodies of this size can also be panel-mounted.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, standard or low-pressure types, gauge scales in MPa, psi or bar, and optional G (BSPP) or NPT threads in place of the PT standard. Because published flow data appears as curves rather than a single rated figure, we confirm the datasheet and sizing 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.
| 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. |
| (blank) | Fixing bracket included. |
| (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. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
| 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.

Holds the reduced actuation pressure that pneumatic hold-down clamps need, so panels are pressed firmly without crushing, with the check valve keeping clamp force if supply pressure dips.
Supplies the low, steady control pressure that big diaphragm and gate valve actuators require, with the 1 in port feeding multiple valve positions from one regulating point.
Regulates the gentle, consistent pressure that product-handling gate and diverter cylinders need, so bottles are diverted without jolts or jams at changeover speeds.
Start with the port step: GR comes in 200, 300, 400 and 600 sizes with ports from 1/8 in up to this 1 in G thread, and the larger the size the greater the flow path - match it to the air demand of the circuit rather than the pipe alone. Choose the standard type for adjustment up to 0.9 MPa, or this low-pressure (L) type when the working setting stays at or below 0.4 MPa. Pick the gauge scale you want (MPa, psi or bar) and embedded square versus optional external round. Thread is PT as standard, with G and NPT as orderable options; a bracket is included and the GR600 is also panel-mountable. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 GR flow data as curves rather than a single rated figure, so we do not quote a flow number. Tell us your inlet pressure, set pressure and the air demand of the circuit, and we will confirm the datasheet curves and correct sizing for your application on request.
L marks the low-pressure type of regulator: its adjustment range tops out at 0.4 MPa instead of the standard type's higher range. Choose it when your process runs at low settings and you want finer, more usable adjustment there; choose the standard type if you need to regulate above 0.4 MPa. This unit also carries a square gauge reading in psi and a fitted reverse (check) valve.
