The AirTAC GR600-25LJF2G AirTAC Air Pressure Regulator, G1 Port 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 GR600-25LJF2G is an AirTAC GR-series air pressure regulator: it does one job, holding a steady downstream air pressure from a compressed-air supply, and it carries no filter, bowl or lubricator. This is the 600 size with a 1 in (G1) female port in G (BSPP) thread, built as the low-pressure type, so its adjustment range tops out at 0.4 MPa - the right choice where downstream equipment must never see full line pressure. Maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -20 to 70 C, wider than the rest of the G-series family. A square pressure gauge scaled in psi is included, and this configuration is supplied without a mounting bracket (the GR can also be panel-mounted).
This is a genuine AirTAC part. The GR family spans four sizes (200, 300, 400, 600) with ports from 1/8 in to 1 in, standard and low-pressure types, gauge or no gauge, MPa/psi/bar scales, optional reverse/check valve, and G, NPT or PT threads. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing for your application before ordering.

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. |
| (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. |
| (blank) | No reverse-flow valve (the default). |
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.

Feeding sealing or folding cylinders on a packaging line that must run at a reduced, stable pressure below 0.4 MPa, with the psi gauge letting operators set and check the value at the machine.
Supplying gentle, steady air to tension rollers, low-pressure actuators or hold-down devices on converting machinery, where the low-pressure type prevents over-pressurising delicate mechanisms.
Installed on a 1 in branch off the main header to drop pressure for a workshop zone, with the wide -20 to 70 C temperature range suiting unheated plant areas.
Start with the port step: the 600 size carries the largest ports in the GR range (up to 1 in), so it suits the highest-air-demand drops; smaller 200/300/400 sizes cover lighter lines. Then set the type: this unit is the low-pressure (L) version, adjustable up to 0.4 MPa - pick the standard GR if you need settings above that. Choose the gauge scale you want (this one is square, psi; MPa and bar scales exist), the thread (PT is the standard; G and NPT are order options), and whether you want a bracket (this code is J, no bracket) or panel mounting. We do not quote a single rated flow figure because AirTAC publishes flow as curves - send us your application and we will confirm sizing 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 curves, not as a single rated number, so we do not quote a l/min, m3/h or SCFM figure here. Ask us and we will confirm the flow curve and datasheet for this 600-size, 1 in port unit against your application before you order.
The L in the code marks the low-pressure type, whose adjustment range tops out at 0.4 MPa. If your application needs settings above that, order the standard GR600 in the same size and port instead - both share the 1.0 MPa (145 psi) maximum inlet pressure.
