The AirTAC GR60020LJC2 AirTAC Air Pressure Regulator 3/4 in PT 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 GR60020LJC2 is a genuine AirTAC GR-series air pressure regulator: it does one job, holding downstream pressure steady, and it does nothing else - no filter, no bowl, no lubrication. This is the 600 size, the largest in the GR range, with a 3/4 in PT port, and it is the low-pressure (L) type, so its adjustment range tops out at 0.4 MPa instead of the standard 0.9 MPa - the right choice for circuits that must never see high pressure. A round pressure gauge reading in psi is fitted, and the unit ships without a mounting bracket, though the GR body is also panel-mountable.
The GR family spans sizes 200 to 600, so you can step port size up or down as your flow demand changes, with standard or low-pressure regulation, gauge or no gauge, and PT, G (BSPP) or NPT threads as order options. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures against 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. |

| (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.

Packaging machinery with grippers and light-duty pneumatic actuators often needs a deliberately capped supply pressure. This low-pressure GR regulator, set up to 0.4 MPa, holds a gentle, steady downstream pressure so delicate product-handling motions stay consistent through the shift.
Web-handling equipment - textile frames, film converters, printing auxiliaries - uses low-pressure air to float or guide material without marking it. A dedicated 3/4 in low-pressure regulator branch keeps that circuit separate from the main high-pressure plant air and holds it stable.
Cooling, drying and debris-blowing stations on production lines run best at a fixed, modest pressure rather than full line pressure. This regulator lets the station be tuned to the job, and the fitted round psi gauge gives operators a direct reading of the set point.
Start with the port: this unit is 3/4 in PT, and the 600 size is where the GR range carries the largest ports - match the port step to the flow your line needs and step up or down a size if it does not. Then choose the regulation type: this is the low-pressure (L) version, adjusting up to 0.4 MPa; if your circuit needs up to 0.9 MPa, the standard type is the correct pick instead. Gauge scale (MPa, psi or bar), thread (PT standard, G or NPT to order) and bracket or no bracket are the remaining decodable choices. One honest note on sizing: flow for the GR series is published as curves, not a single rated number, so send us your application and we will confirm the right size before you order.
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 on the datasheet rather than as a single rated number, so we do not quote a l/min, m3/h or SCFM figure. Tell us your application and we will confirm the flow figures from the datasheet against your requirement before you order.
The L in the code marks the low-pressure regulator type: its adjustment range tops out at 0.4 MPa, instead of the standard GR type's 0.9 MPa. It is chosen for circuits that must be capped well below normal plant air pressure. Maximum inlet pressure is still 1.0 MPa (145 psi), and service temperature is -20 to 70 C.
