The AirTAC GR60020LF2G AirTAC Air Pressure 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 GR60020LF2G is an AirTAC GR-series air pressure regulator in the largest GR600 size, built for one job only: holding a steady downstream air pressure. This is the low-pressure (L) type, so its regulation range goes up to 0.4 MPa, with a maximum working (inlet) pressure of 1.0 MPa (145 psi). The port is G3/4 (3/4 in) with G (BSPP) threads, and the unit carries an embedded square pressure gauge reading in psi; an external round gauge is available as an option. As a pure regulator it has no filter, no bowl and no drain, and it operates in ambient temperatures from -20 to 70 C - a wider range than the rest of the G-series. A mounting bracket is included, and the GR600 can also be panel-mounted.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with matching ports, and each size can be ordered with PT (standard), G or NPT threads, different gauge scales, a reverse/check valve (K), the low-pressure type (L), or no gauge (N). Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet 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.

| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |

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.

Feeding baggers, carton sealers or wrapping heads that run on gentle, stable air: the low-pressure type holds the line at or below 0.4 MPa downstream of the main plant regulator.
Setting a fixed, repeatable clamping pressure for fixtures and workholding on a machining cell, where over-pressure would mark or crush the part and the psi gauge makes setpoint checks quick.
Trimming atomising and conveying air on a paint or coating booth to a controlled low pressure, with the 3/4 in port serving the larger supply line to the booth.
Start with the port step: GR600 takes a 3/4 in line, the largest in the GR range (200/300/400/600), so match the size to the air demand of the circuit - flow is published as curves, not a single rating, so let us confirm sizing against your application before you order. Because this code is the low-pressure (L) type, choose it where the set pressure must stay at or below 0.4 MPa; for higher setpoints use the standard GR version. The embedded square gauge here reads in psi, and MPa or bar scales are order options if you prefer. Thread is G (BSPP) on this unit, with PT (the standard) and NPT available to order. A reverse/check valve (K) can be added if you need to hold downstream pressure on supply failure, and a bracket is included with panel mounting also possible on GR.
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 GR flow as curves, not as a single rated figure, so we do not quote a number here. Tell us your line size and air demand and we will confirm the flow figures from the datasheet for this exact model on request before you order.
The L in the code marks the low-pressure version: its regulation range goes up to 0.4 MPa instead of the standard GR range. Maximum inlet pressure is still 1.0 MPa (145 psi). Choose this code when your process setpoint sits in the low band; use a standard GR600 code for higher setpoints.
