The AirTAC GR60020LJC2TK AirTAC Air Pressure Regulator, NPT3/4 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 GR60020LJC2TK is an AirTAC GR600 series air pressure regulator for compressed air, built for applications that need a limited downstream pressure rather than the full standard range. This is the low-pressure type (code L), with an adjustment range up to 0.4 MPa, in the largest 600 size with a 3/4 in NPT port. The code also specifies an external round pressure gauge with a psi scale (C2) and a built-in reverse/check valve (K), which holds the set pressure downstream if the upstream supply is interrupted. No mounting bracket is fitted (J), and the GR body is also panel-mountable.
This is a genuine AirTAC part. The GR series spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, in standard and low-pressure types, with optional G (BSPP) or NPT threads in place of the PT standard, gauge choices, a reverse/check valve option, and bracket or no-bracket variants. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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.
| 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. |
| 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.

A 3/4 in supply feeding large air cylinders or air bellows on a carton-forming or wrapping machine, where the actuator circuit is designed to run at a reduced setpoint below the main header pressure and a check valve keeps the setting if supply drops.
A main plant air distribution point serving a low-pressure process branch, where the 600-size body and 3/4 in NPT connection sit in the header line and the round psi gauge gives operators a direct local reading of the branch setpoint.
A workholding or clamping circuit on a machining fixture that must be held at a controlled low pressure to avoid distorting the part, with the regulator set well below line pressure and the check valve holding the clamp setting during supply dips.
Start with the port size: this unit is the 600 size with a 3/4 in NPT port, the largest step in the GR range; smaller 200/300/400 sizes with 1/8 to 1/2 in ports exist if your line does not need the 3/4 in connection. Because this is the L (low-pressure) type, it suits circuits set up to 0.4 MPa; if your setpoint must reach 0.9 MPa, choose the standard GR type instead. The C2 code gives you an external round gauge reading in psi; square embedded gauges with MPa, psi or bar scales are the alternative. Thread is NPT here, and PT is the catalogue standard with G (BSPP) available to order. The J code means no mounting bracket is supplied, though the unit is panel-mountable.
One honest note on sizing: AirTAC publishes GR flow as curves, not as a single rated number, so we cannot quote you a flow figure here. Send us your application details and we will confirm the flow and datasheet figures against this exact model 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.
We do not quote a single rated flow figure because AirTAC publishes GR-series flow as performance curves, not as one rated number, and we will not estimate one. Send us your application details and we will confirm the flow and full datasheet figures for this exact model on request before you order.
The L in the code marks this as the low-pressure type of the GR series, whose adjustment range tops out at 0.4 MPa; the standard GR type adjusts up to 0.9 MPa if you need more. The trailing T means this unit has an NPT thread (NPT3/4); PT is the catalogue standard thread, and G (BSPP) is available as an order option.
