The AirTAC GR60020LJC1T AirTAC Air Pressure Regulator, NPT 3/4 in 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 GR60020LJC1T is an AirTAC GR-series air pressure regulator: it does one job, holding downstream pressure steady on a compressed-air line. This is the 600 size, the largest in the GR range, with a 3/4 in NPT port, and it is the low-pressure type, adjusting outlet pressure up to 0.4 MPa. It is fitted with an external round gauge scaled in MPa so the set point is readable at the unit, and it has no mounting bracket, so it mounts directly on the line or panel.
This is a genuine AirTAC part. The GR series spans sizes 200 to 600 with port sizes from 1/8 in to 1 in, gauge and thread options to order, and the regulator is also panel-mountable. We confirm flow and datasheet figures on request - flow for this series is published as curves rather than a single rated number.

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. |
| (blank) | No reverse-flow valve (the default). |
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.

Drops a plant air main down to a steady low-pressure supply for a department or cell that runs its actuators and air tools below 0.4 MPa, with the MPa gauge letting operators read and hold the set point.
Feeds instrument and pilot-air lines on process skids where a gentle, stable low pressure is required, using the 3/4 in NPT connection to sit inline on the control-air takeoff.
Serves a workshop bench that exercises low-pressure pneumatic circuits on commercial-vehicle equipment, where the technician sets a repeatable test pressure below 0.4 MPa and reads it off the round gauge.
Size the GR series by stepping up the size code (200 to 600) as your port and flow demand grows; this unit is the 600 size with a 3/4 in NPT port. The L in the code marks the low-pressure type, which adjusts up to 0.4 MPa - choose the standard type instead if you need the full 0.05-0.9 MPa range. The C1 in this code gives you an external round gauge scaled in MPa; square embedded gauges and psi or bar scales are alternatives. Thread is NPT here; PT is the standard and G (BSPP) is also an order option. This configuration has no mounting bracket, though GR units are panel-mountable. Flow for the series is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 GR-series flow as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure, set pressure and expected air demand and we will confirm the sizing from the datasheet on request.
The L in the code marks the low-pressure type, which adjusts outlet pressure up to 0.4 MPa. If your application needs the full 0.05-0.9 MPa range, order the standard GR type instead - same sizes and ports, wider adjustment range.
