The AirTAC GR60025LC2GK 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 GR60025LC2GK is an AirTAC GR-series air pressure regulator: it does one job, holding a steady downstream pressure from a compressed-air supply, and it carries no filter, no bowl and no lubricator. This is the size 600 unit with a G1 (1 in) G-thread port, built as the low-pressure type with an adjustment range up to 0.4 MPa, so it suits lines that must run well below normal main pressure. It ships from the factory with a round external gauge scaled in psi, a reverse/check valve fitted to hold the downstream setting if upstream pressure is lost, and a mounting bracket included; the GR body is also panel-mountable. 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.
This is a genuine AirTAC part. The GR line spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, standard or low-pressure regulation, a choice of embedded square or external round gauge in MPa, psi or bar scales, an optional reverse/check valve, and PT (standard), G or NPT threads to order. Flow is published as curves rather than a single rated figure, 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. |
| (blank) | Fixing bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. 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.

Feeding air knives that dry or cool product on a conveyor, where the jets must run at a gentle, stable pressure well below the main header - the low-pressure range up to 0.4 MPa and the check valve keep the setting steady.
Regulating the motive air for a dilute-phase conveying line at reduced pressure, with the 1 in G-thread port matching the main supply and the psi gauge letting operators read the setpoint directly.
Supplying the porous cushion deck of a handling conveyor with low, even pressure so cartons glide without marking, with the round psi gauge giving a clear setpoint and the bracket allowing panel or frame mounting.
Start with the port step: size 600 with a G1 (1 in) port is the largest GR frame, so match it to your main line size and required air demand rather than stepping down at the regulator. This code is the low-pressure type, regulated up to 0.4 MPa - if your process needs the standard range up to 0.9 MPa, choose a GR without the L code. The round gauge here reads in psi; MPa and bar scales are also available, and the embedded square gauge is the standard alternative. The trailing G sets the G (BSPP) thread; PT is the catalogue standard and NPT is orderable. A reverse/check valve (K) is fitted, and the mounting bracket is included. Flow is published as curves, not a single rating, so send us your demand figures 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 GR flow as curves against inlet and outlet pressure, not as a single rated figure, so we do not quote a number here. Tell us your line pressure, set pressure and air demand, and we will confirm the flow from the GR600 datasheet and check the sizing for your application before you order.
L marks the low-pressure regulator type: its adjustment range tops out at 0.4 MPa instead of the standard GR range up to 0.9 MPa. It is the right choice for processes that run gently - blow-off, cushioning, conveying - and it still accepts up to 1.0 MPa (145 psi) at the inlet. This unit also carries a round psi gauge, a reverse/check valve (K) and a G (BSPP) thread; PT is the catalogue standard and NPT can be ordered.
