The AirTAC GR60020LJC2T 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 GR60020LJC2T is an AirTAC GR600 air pressure regulator in the 600 size, built for regulation only: it holds a steady downstream pressure from a compressed-air supply, with no filter element, no bowl and no lubricator in the body. This configuration carries an NPT3/4 (3/4 in NPT) port, the low-pressure type with a setting range up to 0.4 MPa, a round external gauge reading in psi, and no mounting bracket - the GR body is also panel-mountable. Maximum 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-series families.
This is a genuine AirTAC part. The GR line runs from size 200 through 600 with port sizes from 1/8 in to 1 in, and options include standard or low-pressure regulation, an embedded square gauge or an external round gauge in MPa, psi or bar scales, a reverse/check valve, and PT, G or NPT threads to order. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application.

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. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |

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 the reduced, stable air pressure that spray guns and atomising lines need, with the low-pressure type keeping settings within a 0.4 MPa ceiling and the psi gauge letting operators check at a glance.
Regulates supply pressure to clamp cylinders on a CNC fixture so holding force stays consistent part after part, with the 3/4 in NPT port feeding a high-consumption clamping manifold.
Sits upstream of valve-and-cylinder circuits on a packaging line, trimming plant supply down to the pressure the machine's actuators were designed for and holding it steady through the shift.
Size the GR600 by the port and the flow your line needs: 600 is the largest G-series size, with a 3/4 in port here in NPT. Because flow is published as curves, not a single rating, send us your required flow and upstream pressure and we will confirm the sizing against the datasheet before you order. This unit is the low-pressure type, so it suits circuits that must be held at or below 0.4 MPa; if your setting range runs higher, the standard GR type (0.05-0.9 MPa) is the alternative. The round gauge on this code reads in psi; square embedded gauges and MPa or bar scales are order options. Thread is NPT here, with PT (standard) and G available to order, and this code omits the mounting bracket - add it back if you need panel or surface mounting.
Quick checklist
Without a reflux valve, air cannot flow back through the regulator — order the K option if reverse flow is required. 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 there is no one flow figure we can honestly quote. Tell us your required flow and upstream pressure and we will confirm the sizing against the datasheet before you order.
The L in the model code marks the low-pressure type, whose setting range tops out at 0.4 MPa - the right choice for circuits that must never see full line pressure. The C2 marks an external round gauge with a psi scale; square embedded gauges and MPa or bar scales are order options.
