The AirTAC GR60020LC2K AirTAC Pressure Regulator PT3/4 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 GR60020LC2K is an AirTAC GR-series air pressure regulator in the large size 600 frame with 3/4 in PT ports. This is a regulation-only unit: it reduces and holds a stable downstream air pressure, with no filter, no drain bowl and no lubricator. The L in the code marks the low-pressure type, so its adjustment range tops out at 0.4 MPa, making it the right choice for circuits that must not see full-line pressure. It is supplied with an external round pressure gauge scaled in psi, and a reverse (check) valve is fitted so downstream pressure is held if the upstream supply drops.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, gauge and scale options, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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.

| L | Low-pressure type — 0.05 - 0.4 MPa (7 - 58 psi). Blank is standard, L is the low-pressure type. |

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

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.

Feeding the film-sealing and clamp circuits of a horizontal wrap machine where the actuator circuit is rated well below main line pressure. The low-pressure type caps the setpoint at 0.4 MPa, and the round psi gauge lets an operator verify the setting at a glance.
Supplying the hold-down and product-divert jets along a bottling or carton conveyor line. The check valve holds the set pressure if the upstream supply dips, so diverted product is not released mid-run, and the 3/4 in ports suit a main distribution leg.
Trimming the auxiliary air circuit of a weaving shed - selvage blow-off, suction assist and frame cleaning - where a stable, modest pressure matters more than volume. The psi-scaled gauge supports routine shift checks without special tools.
Size 600 with 3/4 in ports is the large-flow end of the GR range; step down to 200/300/400 if your line size and air demand are smaller. The low-pressure (L) type is the key choice here: it regulates up to 0.4 MPa, so confirm your setpoint sits below that before ordering - the standard GR type covers up to 0.9 MPa. The round gauge is scaled in psi; MPa and bar scales are available as order options. Thread is PT as standard, with G (BSPP) and NPT as catalogue options. A mounting bracket is included, and the GR can also be panel-mounted.
One honest note on sizing: AirTAC publishes GR flow as curves, not a single rated number, so we do not quote a flow figure here. Send us your line size and demand and we will confirm the datasheet curve against your application 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 GR regulator flow as curves, not as a single rated figure, so we do not quote a flow number here. Tell us your line size and air demand and we will confirm the datasheet curve for this exact model against your application before you order.
The L in the code identifies the low-pressure type, whose adjustment range tops out at 0.4 MPa. Choose this version when your circuit must be limited to that ceiling; the standard GR type covers the full 0.05-0.9 MPa range. Maximum inlet pressure is 1.0 MPa (145 psi) either way, and the fitted round gauge is scaled in psi so the setting can be read directly.
