The AirTAC GR60020LC2GK AirTAC Air 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 GR60020LC2GK is an AirTAC GR-series air pressure regulator: its single job is to hold a steady, reduced downstream air pressure from a higher supply line. This is the 600 size, the largest in the GR range, with G3/4 (BSPP) female ports. It is the low-pressure type, so its adjustment range tops out at 0.4 MPa, and it carries a built-in reverse/check valve (code K) plus a round pressure gauge reading in psi. 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 family.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and options for thread type (PT standard, G and NPT to order), gauge scale (MPa, psi or bar), low-pressure type, reverse/check valve and mounting bracket. Because AirTAC publishes flow as curves rather than a single rated figure, we confirm flow and other datasheet values on request before you order.

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.

On a process line where large pneumatic actuators and diaphragm valves are deliberately run at gentle set-points, this low-pressure GR regulator holds the supply below 0.4 MPa while the round psi gauge gives operators a direct local reading at the 3/4-inch take-off.
At the 3/4-inch branch feeding a wrapping or cartoning machine's air manifold, the regulator sets a stable working pressure for the whole bay, and the built-in check valve keeps downstream pressure from back-feeding the header when the supply is shut off.
Where instrument and pilot-air circuits need a soft, carefully limited supply, the low-pressure adjustment range lets technicians dial in low set-points precisely, with the psi-scaled gauge mounted right on the unit for verification during commissioning.
Start with the port and size: this unit is the 600 frame with G3/4 ports, the step to take when your line is 3/4 inch and your air demand is at the top of the GR range. Because it is the low-pressure (L) type, choose it where the working pressure you need to hold is within 0.4 MPa; for higher set-points, the standard GR type adjusts up to 0.9 MPa. The fitted round gauge reads in psi, which suits US-market panels; MPa and bar scales are the other order options. The G thread here is BSPP; PT is the catalogue standard and NPT is available to order. A mounting bracket is included, and GR is also panel-mountable.
One honest note on sizing: AirTAC publishes regulator flow as curves, not as a single rated number, so we do not quote a flow figure here. Ask us to confirm the curve and check this 600-size unit against your actual air consumption before ordering.
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 regulator flow as performance curves rather than a single rated figure, so we do not state a flow number on the page. Send us your line pressure, set-point and air consumption, and we will confirm the curve data from the datasheet and check that this 600-size unit is correctly sized before you order.
The L in the code marks the low-pressure type, whose adjustment range tops out at 0.4 MPa. It is chosen for circuits that must run at gentle set-points. If you need to regulate up to 0.9 MPa, the standard GR type in the same 600 size and G3/4 port is the correct selection - ask us for that variant.
