The AirTAC GR60020LJC2K AirTAC Air Pressure Regulator PT3/4 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 GR60020LJC2K is an AirTAC GR-series air pressure regulator: it does one job, holding a steady downstream air pressure from a compressed-air supply. This is the size-600 body, the largest in the GR range, with a 3/4 in PT thread. The L in the code marks the low-pressure type, so its adjustment range tops out at 0.4 MPa - the right choice for circuits that run well below standard line pressure. It is supplied with an external round gauge scaled in psi and a built-in reverse (check) valve that lets downstream pressure hold when the upstream supply is cut. No bracket is fitted; as a GR unit it can also be panel-mounted.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, standard or low-pressure regulation, gauge and scale choices, and an optional reverse valve. 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.

|---|---|
| 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. |

| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |

| 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 an assembly press that clamps or forming tool that must not exceed a modest setpoint, this low-pressure GR600 regulator holds the working pressure steady at the 3/4 in drop from the main header, with the psi gauge giving the operator a direct read of the set pressure.
Spray guns and booth atomising air run at reduced pressure, and this size-600 regulator on the booth's 3/4 in supply line lets the finisher dial in and hold a repeatable low setpoint, with the check valve keeping the line from dumping back when the upstream supply is shut off.
Looms and textile air-jet equipment often run sensitive low-pressure circuits off a shared compressor. A GR600 low-pressure regulator on the 3/4 in branch keeps that circuit isolated from header pressure swings, with the round psi gauge letting maintenance verify the setting at a glance.
Start with the port step: size 600 carries a 3/4 in PT thread, and the larger the size the greater the flow path - match the size to the air demand of the circuit rather than to the pipe alone. This unit is the low-pressure (L) type, adjusting up to 0.4 MPa; if your setpoint sits near standard line pressure, the standard GR type with its wider range is the correct pick instead. The gauge here is the external round type scaled in psi; embedded square gauges and MPa or bar scales are the other catalogue options. The K code adds a reverse (check) valve, and J means no mounting bracket is supplied - order a bracket variant if you want one. Thread is PT as standard, with G (BSPP) and NPT available as order options. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing from 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 regulator flow as curves, not as a single rated number, so we do not quote a l/min or SCFM figure. Tell us your upstream pressure, set pressure and the air demand of the circuit, and we will confirm the sizing against the GR600 datasheet flow curve on request before you order.
L marks the low-pressure type: its adjustment range tops out at 0.4 MPa, versus the wider range of the standard GR. Choose L when the circuit must run at a modest setpoint; choose the standard type when you need regulation up toward full line pressure. Both share the same size-600 body and 3/4 in PT port.
