The AirTAC AirTAC GR60025LC2TK Regulator NPT1 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 AirTAC GR60025LC2TK is a pure air pressure regulator: it controls downstream pressure only, with no filter, no bowl and no lubrication function. This 600-size unit is the low-pressure type, so its setting range tops out at 0.4 MPa, and it is fitted with a round pressure gauge reading in psi plus a reverse (check) valve that holds the set pressure if the upstream supply is lost. The 1 in NPT port suits larger supply mains, and the mounting bracket is included; the GR body is also panel-mountable.
This is a genuine AirTAC part from the GR series, which spans sizes 200 to 600 with port options from 1/8 in up to 1 in, standard or low-pressure regulation, gauge choices and scale options, and PT, G or NPT threads. Flow figures for the GR series are published as curves rather than a single rating, so we confirm the datasheet and sizing on request before you order.

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. |
| T | NPT 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.

On a process line where diaphragm or piston valves are specified for actuation pressures at or below 0.4 MPa, this regulator sets and holds the supply pressure to the valve pilot network, with the check valve holding the setting through upstream dips.
On a CNC fixture line using low-pressure pneumatic clamps, the GR60025LC2TK regulates the clamp circuit at a gentle set point so delicate workpieces are held without over-clamping, and the psi gauge lets operators verify the setting at the machine.
On a packaging line where sealing bars, hold-downs or product-transfer actuators run at reduced pressure, this 1 in regulator conditions the machine's air supply branch, and the reverse valve prevents the set pressure from bleeding back if the main drops.
Choose the GR size by the port step and the flow your line needs: this GR600 is the largest, with a 1 in NPT port. Pick the low-pressure type (L) only when your set point stays at or below 0.4 MPa; for higher settings use the standard GR. Select the gauge style and scale you want - this unit ships with a round gauge in psi - and add the K reverse valve if the downstream pressure must be held through supply dips. Thread is your order choice: PT is the catalogue standard, with G and NPT as options; this code specifies NPT. Bracket is included on GR units.
Flow for the GR series is published as curves, not a single rated number, so send us your application details 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-series flow as curves rather than a single rated figure, so there is no one rated flow number we can quote. Send us your inlet pressure, set point and expected air demand, and we will confirm the sizing from the datasheet on request before you order.
The L in the code marks the low-pressure type: its adjustment range tops out at 0.4 MPa. It is intended for circuits that must never see a high setting. If your process needs settings above 0.4 MPa, order the standard GR version of the same size instead. This unit also carries a round psi gauge and a K reverse (check) valve, and the maximum inlet pressure remains 1.0 MPa (145 psi).
