The AirTAC GR60020LC1T AirTAC Air Regulator NPT3/4 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 AirTAC GR60020LC1T is a low-pressure air pressure regulator in the GR600 size, with a 3/4 in NPT port. As an L-type unit it holds downstream pressure anywhere in its setting range up to 0.4 MPa, making it the right choice for circuits that run well below standard line pressure. It handles a maximum inlet pressure of 1.0 MPa (145 psi) and operates from -20 to 70 C, the widest temperature window in the G-series. This configuration ships with an external round pressure gauge scaled in MPa and includes a mounting bracket; 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 to 1 in, standard or low-pressure regulation, gauge scale options in MPa, psi or bar, and PT, G or NPT threads to order. Flow is published in the catalogue 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.

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 machining or assembly line where fixtures clamp with air held well below standard line pressure, this low-pressure GR600 regulator holds the downstream setting up to 0.4 MPa at a 3/4 in supply, with the MPa gauge letting operators verify the clamp circuit at a glance.
Bench-scale reactors, agitated vessels and pneumatic dosing stations in a pilot plant often need gentle, stable air at reduced pressure. The GR60020LC1T steps the 3/4 in plant air down into the low-pressure band, and its -20 to 70 C window suits unheated service rooms.
A packaging line's air header feeding actuators, vacuum generators and sealing cylinders can be regulated zone by zone. Mounted on the 3/4 in drop with its included bracket, this regulator gives one zone its own low-pressure setting independent of the main header.
Start with the port step: this GR600 is the largest GR size with a 3/4 in NPT port, the natural pick when your line runs 3/4 in piping and you want the regulator body sized generously for the circuit. The L code is the decisive decode here: this is the low-pressure type, limited to settings up to 0.4 MPa, so choose it only if your downstream target pressure sits in that band; for higher settings pick the standard GR type. The C1 suffix gives you an external round gauge scaled in MPa; psi (scale 2) or bar (scale 3) are available if your team reads in those units. Thread is NPT on this code, with PT (the standard) and G as orderable alternatives. A mounting bracket is included, and the GR can also be panel-mounted. Because AirTAC publishes regulator flow as curves rather than one rated number, send us your flow and pressure targets 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 in the catalogue, not as a single rated number, so we do not quote a flow figure here. Tell us your upstream pressure, set pressure and air demand, and we will confirm the sizing from the datasheet on request before you order.
L marks the low-pressure type: the adjustment range tops out at 0.4 MPa instead of the standard GR range. It is intended for circuits that run at reduced pressure. The rest of the decode is unchanged - 3/4 in NPT port, 1.0 MPa maximum inlet, -20 to 70 C operation, round MPa gauge fitted and bracket included.
