The AirTAC GR60020LJF2GK AirTAC Low-Pressure Regulator G3/4 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 GR60020LJF2GK is an AirTAC GR-series air pressure regulator: it does one job, holding downstream pressure steady, and it does nothing else - no filter, no bowl, no drain, no lubrication. This is the low-pressure type (code L), with an adjustment range of up to 0.4 MPa, sized 600 with a G3/4 (3/4 in) BSPP parallel port. The trailing G sets the thread to G; PT is the standard thread and G or NPT are catalogue options to order. It ships configured with an embedded square gauge reading in psi (an external round gauge is optional), a built-in reverse/check valve (code K), and no mounting bracket (code J) - the GR body is also panel-mountable. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the working temperature range is -20 to 70 C, wider than the rest of the G family.
This is a genuine AirTAC part. The GR series is available in sizes 200, 300, 400 and 600 with matching ports, in standard and low-pressure types, with or without bracket, gauge and check valve. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and flow 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.
| 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). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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 carton-sealing or wrapping line where delicate actuators and grippers run at reduced pressure, the GR60020LJF2GK holds a steady low setpoint on a 3/4 in supply leg, with the psi gauge giving operators a direct readout at the machine.
Workholding clamps and swing cylinders on a CNC fixture table need consistent, moderate pressure to avoid distorting the part. This low-pressure regulator sits in the 3/4 in branch feeding the fixture manifold, and the check valve holds the clamp circuit if upstream air drops.
Pneumatic gate and diverter cylinders on a bottle-filling conveyor run best at a gentle, stable pressure to prevent product damage. The GR60020LJF2GK regulates that 3/4 in branch, and its -20 to 70 C range suits chilled production areas.
Start with the port step: GR comes in sizes 200 through 600, and the 600 size with its 3/4 in port is the step to choose when the line and the connected cylinders or actuators demand the larger bore - match the size to the required flow, which we confirm against the published curves before you order. This unit is the low-pressure type, so it is the right pick only where the setpoint stays within its up-to-0.4 MPa range; for higher setpoints choose a standard GR. Decide the gauge scale (MPa, psi or bar) - this one reads psi - and whether you want the embedded square gauge or an external round one. Choose the thread: PT is standard, G and NPT are order options. The check valve (code K) lets downstream pressure hold when upstream supply is removed; leave it off if you do not need that. Bracket J means no bracket is fitted, but the GR is panel-mountable either way.
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 curves, not as a single rated number, so there is no one flow figure we can honestly quote. Tell us your line pressure, setpoint and the air demand of the connected equipment, and we will confirm the correct sizing against the datasheet curves on request before you order.
The L in the code marks the low-pressure regulator type: its adjustment range goes up to 0.4 MPa, instead of the standard GR range, so use it where the setpoint is low. The embedded square gauge on this unit reads in psi; gauge scale (MPa, psi or bar) and an external round gauge are order options. Thread is G on this model, with PT standard and G or NPT available to order.
