The AirTAC GR60020LF2 AirTAC Low-Pressure Regulator PT3/4 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 GR60020LF2 is an AirTAC GR600 low-pressure air pressure regulator with a PT3/4 (3/4 in) PT port. It is a regulation-only unit: it reduces and holds downstream pressure anywhere in its adjustment range up to 0.4 MPa, with a maximum inlet pressure of 1.0 MPa (145 psi). The embedded square gauge fitted as standard is scaled in psi, and an external round gauge is available as an option. A mounting bracket is included, and the GR600 can also be panel-mounted. There is no filter, no bowl and no drain on this model - it does one job, which is holding a steady, lower pressure downstream. It operates in ambient and medium temperatures from -20 to 70 C (non-freezing), a wider window than the rest of the G-series family.
This is a genuine AirTAC part. The GR series spans sizes 200, 300, 400 and 600, covering ports from 1/8 in to 1 in, with PT thread as standard and G (BSPP) or NPT available as order options. Flow figures for this series are published as curves rather than a single rated number, so we confirm the datasheet and sizing 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.

Holds a steady low pressure to spray guns and atomising air on a paint or coating line, where the 3/4 in port feeds a manifold serving multiple guns.
Regulates the low-pressure air feeding baggers, carton sealers and other pneumatic actuators on a packaging line, keeping cylinder action consistent as upstream pressure wanders.
Sets a repeatable low supply pressure on a lab or QC test bench, with the psi-scaled square gauge giving operators a direct local readout of the set point.
Choose the GR size by port and flow demand: this 600 size carries a 3/4 in PT port at the top of the range for higher-flow lines. The L in the code marks the low-pressure type, adjustable up to 0.4 MPa - pick the standard GR type instead if you need regulation up to 0.9 MPa. The F2 suffix gives you the embedded square gauge with a psi scale; MPa or bar scales and an external round gauge are alternatives. Thread is PT as standard on this code, with G (BSPP) and NPT as order options, and the mounting bracket is included (order the J variant if you do not want it). AirTAC publishes flow for the GR series as curves, not a single rating, so ask us to confirm sizing against 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 flow for the GR series as curves rather than a single rated figure, so there is no honest one-number answer. Tell us your inlet pressure, set pressure and the equipment downstream, and we will confirm the flow and sizing from the datasheet on request before you order.
L marks the low-pressure type: this regulator adjusts up to 0.4 MPa instead of the standard GR range up to 0.9 MPa. F2 means the embedded square gauge is fitted with a psi scale; MPa or bar scales and an external round gauge are available as options.
