The AirTAC GR60020LJC1TK AirTAC Air Regulator 3/4in NPT 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 PT3/4" 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 GR60020LJC1TK is a genuine AirTAC GR600 air pressure regulator in the 600 size with a 3/4 in NPT port. It is the low-pressure (L) type, so its setting range tops out at 0.4 MPa, and it carries no filter, bowl or lubricator - its single job is holding downstream pressure steady on a compressed-air line. This configuration is fitted with a round external gauge scaled in MPa and a reverse (check) valve, and it ships without a mounting bracket; the GR body is also panel-mountable.
The GR600 series is the largest step in AirTAC's G-series regulator range, which spans the 200, 300, 400 and 600 sizes with a choice of PT, G or NPT threads, standard or low-pressure regulation, gauge style and scale, and bracket options. Maximum working (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 family. Flow is published as curves rather than a single rating, so ask us to confirm the sizing figures against 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.
| GR600 | G-series pressure regulator, 600 body — sets the port range. |
|---|---|
| 20 | Port size PT3/4". 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). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 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.

Holds a gentle, steady supply pressure to air cylinders and clamps on carton-forming or wrapping stations where the process calls for a low setpoint, with the check valve keeping the setting stable if the main supply dips.
Regulates the compressed air feeding looms, winders and fabric-handling jets, where delicate pneumatic functions need a stable low-pressure setting maintained across a long production shift.
Provides a trimmed low-pressure air supply to valve positioners, pilot actuators and pneumatic control panels in a plant, with the MPa gauge giving the operator a clear local reading at the panel.
Start with the port step: this unit is the 600 size at 3/4 in NPT, the largest port in the GR range, so match it to your line size and the flow your circuit needs - we can confirm the flow curve for the GR600 on request, since AirTAC publishes flow as curves rather than one rated number. Choose the low-pressure (L) type only when your setpoint stays at or below 0.4 MPa; for higher setpoints up to 0.9 MPa, the standard GR type is the correct pick. This code comes with a round gauge scaled in MPa (square-gauge and psi/bar scale options exist in the series), a built-in reverse/check valve to hold downstream pressure on supply loss, no mounting bracket, and an NPT thread - PT is the standard thread, with G and NPT as orderable options.
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 regulator flow as characteristic curves rather than a single rated figure, so we do not quote a rated flow number. Tell us your inlet pressure, setpoint and expected air demand, and we will confirm the sizing from the GR600 datasheet on request before you order.
L marks the low-pressure type: its adjustment range tops out at 0.4 MPa instead of the standard regulator's higher range, so pick it only for genuinely low setpoints. The K in the code means a reverse (check) valve is fitted, which holds downstream pressure if the upstream supply is lost. This unit also carries a round gauge scaled in MPa.
