The AirTAC GR60025LF2G 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 GR60025LF2G is an AirTAC GR-series air pressure regulator: it does one job, holding downstream pressure steady, and carries no filter, no bowl and no lubricator. This is the 600 size with a G1 (1 in) G-thread port, built as the low-pressure type with an adjustment range up to 0.4 MPa. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -20 to 70 C (wider than the rest of the G family), and the embedded square gauge fitted to this code reads in psi. A mounting bracket is included, and the body is also panel-mountable.
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, gauge scales in MPa, psi or bar, an optional reverse/check valve, and PT as the standard thread with G and NPT available as order options. 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. |
| 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.

Spray booths and finishing lines run atomising air at modest, tightly held pressures. A low-pressure GR600 regulator on the 1 in supply header keeps the gun-feed pressure steady so finish quality does not drift as demand along the header changes.
Test rigs and pilot lines often need a gentle, stable supply pressure well below normal line pressure. This low-pressure type, set under 0.4 MPa with its psi gauge in view, gives technicians a clear, repeatable setting on a 1 in drop from the building main.
Workshops testing pneumatic brake and suspension components need a controlled low-pressure feed from the shop compressor. The 1 in port suits a bench supply line, and the included bracket lets the regulator be fixed at eye level next to the gauge.
Start with the port step: the 600 size takes a 1 in connection, so match it to your line size and the flow your circuit needs - moving up a size lowers pressure loss at a given demand. This code is the L low-pressure type, correct where the controlled pressure must stay at or below 0.4 MPa; if your process needs the full 0.05-0.9 MPa range, choose a standard GR instead. The fitted square gauge reads in psi; MPa and bar scales are available. Thread is G (BSPP) on this code, with PT standard and NPT offered - pick the one your pipework uses. A bracket is included and the unit can also be panel-mounted.
One honest note on sizing: AirTAC publishes regulator flow as curves, not as a single rated number, so we do not quote a flow figure here. Tell us your line pressure, set pressure and expected air demand, and we will confirm the right size against the datasheet before you order.
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 figure, so we do not quote a number here. Send us your inlet pressure, set pressure and expected air consumption, and we will confirm the flow data from the datasheet for this exact 600-size, 1 in unit on request.
The L in the code marks the low-pressure type, whose adjustment range tops out at 0.4 MPa - useful where the process must never see high pressure. If your application needs settings up to the full 0.05-0.9 MPa range, order a standard GR600 in the same size and port instead; the low-pressure limit is a decode choice, not a fault.
