The AirTAC GR60020LJC2G AirTAC Air Pressure Regulator G3/4 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 GR60020LJC2G is an AirTAC GR-series air pressure regulator: it does one job, holding downstream pressure steady, and carries no filter, bowl, drain or lubricator. This 600-size unit is the low-pressure type, so its regulation range tops out at 0.4 MPa, and it is built around G3/4 (BSPP) ports with the G thread option specified. A round external gauge scaled in psi is fitted so the set pressure is visible at the panel, and the J code means no mounting bracket is supplied - the GR body is also panel-mountable. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature span is -20 to 70 C, wider than the rest of the G family.
This is a genuine AirTAC part. The GR line spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options include PT (standard), G or NPT threads, standard or low-pressure regulation, embedded square or external round gauges in MPa, psi or bar scales, a reverse/check valve, and bracket or no-bracket mounting. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application on request.

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.

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.

Jig and clamp cylinders on carton-sealing or case-packing lines often run at gentle setpoints well below a standard regulator's range. This low-pressure GR holds the holding force steady at the 3/4 in supply take-off, with the psi gauge letting an operator read the setting without tools.
Blow-off and air-knife manifolds that strip rinse water from bottles are usually run at low, carefully set pressures to avoid disturbing labels. A 3/4 in low-pressure regulator at the manifold inlet keeps that setting constant across a shift, and the round psi gauge makes the setpoint visible to line staff.
Atomizing and shaping air to spray nozzles in a coating booth needs a stable, low setpoint or the film build changes between panels. This regulator, plumbed into the 3/4 in drop to the booth, holds that pressure steady while the psi gauge documents the setting for process records.
Start with the port step: 3/4 in on this 600-size body suits lines where larger supply piping is already in place, and the size you pick should be stepped up if the circuit needs more flow - we confirm sizing against the published flow curves before you order. Because this is the L (low-pressure) type, its adjustment tops out at 0.4 MPa; if your setpoint can go higher, choose a standard GR instead. Then settle the decode choices: gauge style and scale (this unit carries an external round gauge in psi; embedded square gauges and MPa/bar scales are alternatives), thread (PT is the standard, G and NPT are order options), and bracket or no-bracket mounting. Note that flow is published as curves, not a single rating, so ask us to confirm the figure for 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 regulator flow as curves rather than a single rated figure, so we do not quote one number. Tell us your inlet pressure, setpoint and expected demand, and we will confirm the flow from the datasheet curves for this exact model on request before you order.
The L in GR60020LJC2G marks the low-pressure regulator type, whose adjustment range tops out at 0.4 MPa - choose a standard GR if you need to set higher. C2 means an external round gauge is fitted, scaled in psi; an embedded square gauge and MPa or bar scales are the other catalogue choices. The J means no mounting bracket is supplied, though the body is panel-mountable.
