The AirTAC GR60020LF2GK 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 GR60020LF2GK is an AirTAC GR-series air pressure regulator: it does one job only, holding a stable downstream pressure from your compressed-air supply. This is the size-600 unit, 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 is built for circuits that never need more than that. The embedded square gauge (psi scale) is fitted as standard, a reverse/check valve is fitted, and the mounting bracket is included; the GR body is also panel-mountable.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, standard or low-pressure regulation, gauge and scale choices, an optional reverse/check valve, and G (BSPP) or NPT threads as order options alongside the PT standard. Max 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-series. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application.

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 carton-sealing or wrapping line where actuated cylinders and clamps run at gentle setpoints, this size-600 regulator holds the downstream pressure steady at the header, with the psi gauge giving operators a direct local readout.
For a broad conveyor installation using air bearings, blow-off nozzles or pneumatic tensioners fed from a large-diameter main, the G3/4 ports and size-600 body match the line, and the check valve keeps downstream pressure from back-feeding.
Bench rigs, environmental chambers and pilot-plant skids that specify a low setpoint ceiling benefit from the 0.4 MPa low-pressure adjustment range, with the fitted gauge letting technicians verify the setting at the point of use.
Start with the port and size step: this unit is size 600 with G3/4 ports, the top of the GR range, so step down to GR200/GR300/GR400 if your line is smaller - size up when flow demand across the circuit calls for it, and we will confirm the flow curves against your application before you order. Next, confirm the regulation ceiling: this is the L low-pressure type, adjustable up to 0.4 MPa; if your process needs up to 0.9 MPa, choose the standard GR type instead. The fitted square gauge reads in psi; MPa and bar scales and an external round gauge are the other catalogue choices. The K in the code means a reverse/check valve is fitted, and the bracket is included. Thread is G (BSPP) here; PT is the standard and NPT is available to 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 flow as curves, not as a single rated number, so we do not quote a Cv, l/min or SCFM figure. Tell us your inlet pressure, setpoint and the flow your circuit needs, and we will confirm the sizing from the datasheet curves before you order.
The L in the code marks the low-pressure type, whose adjustment range goes up to 0.4 MPa rather than the standard type's higher ceiling - correct for circuits that must never see more. This unit also carries a fitted embedded square gauge reading in psi, a reverse/check valve (code K), and an included mounting bracket; the body is panel-mountable as well. Temperature range is -20 to 70 C and max inlet pressure is 1.0 MPa (145 psi).
