The AirTAC GR60020LF2T AirTAC Air Pressure Regulator NPT3/4 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 GR60020LF2T is an AirTAC GR-series air pressure regulator: it does one job, holding your downstream pressure steady as upstream supply and air demand fluctuate. This is the 600 size with 3/4 in NPT ports, the low-pressure type regulating up to 0.4 MPa, and it comes with the embedded square gauge scaled in psi so you can set and read your working pressure directly. 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, which suits colder shops and outdoor equipment.
This is a genuine AirTAC part. The GR line spans sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, standard or low-pressure regulation, gauge scale choices, and G or NPT thread variants alongside the PT standard. Flow for this regulator is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures against your application 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.

| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |

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 packaging and assembly machines that run air cylinders at deliberately low working pressures, this regulator holds the circuit steady up to 0.4 MPa, protecting gentle clamping and positioning strokes from supply swings.
Where a 3/4 in main feeds blowoff nozzles or air knives that clear dust and debris from a conveyor line, this regulator sets a stable, low blowing pressure so product is not disturbed and air is not wasted.
At a department-level drop from a factory compressed-air main, this 600-size regulator supplies a production cell with a steady, reduced pressure, with the psi gauge giving operators a clear local setpoint.
Start with the port step: this unit is 3/4 in NPT, the largest standard port in the GR range, so size up to the 600 series when your line runs a large main or serves several downstream take-offs. Because this is the low-pressure (L) type, it regulates up to 0.4 MPa - choose it for circuits that run deliberately low, and pick the standard type instead if you need the full 0.05-0.9 MPa range. The square gauge here reads in psi; MPa and bar scales are orderable alternatives, and an external round gauge is also available. PT is the standard thread; G (BSPP) and NPT are catalogue options to order, as coded by the trailing T here. A mounting bracket is included, and GR also panel-mounts. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing against the datasheet before you order.
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 regulator flow as performance curves rather than a single rated figure, so there is no one Cv or l/min number we can honestly quote. Tell us your line pressure, set pressure and the equipment you are feeding, and we will confirm the flow and sizing from the datasheet on request before you order.
The L in the code marks the low-pressure type, which regulates up to 0.4 MPa. If your circuit needs the standard range of 0.05-0.9 MPa, order the GR600 in the standard type instead - same size and port, different regulation range. Maximum inlet pressure is 1.0 MPa (145 psi) either way.
