The AirTAC GR60020LC3T 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 AirTAC GR60020LC3T is a size 600 air pressure regulator that does one job only: it reduces and holds a stable downstream pressure from your compressed-air supply. This configuration is the low-pressure type, so the setting range tops out at 0.4 MPa, and it carries a round external gauge scaled in bar so operators can read and adjust the set point directly at the unit. The 3/4 inch NPT ports suit larger main lines, a mounting bracket is included, and the GR body is also panel-mountable. As a pure regulator it contains no filter and no bowl, so it should sit downstream of filtration where clean air is needed.
This is a genuine AirTAC part from the GR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch and standard or low-pressure regulation. Flow figures for GR regulators are published as curves rather than a single rated number, so ask us and we will confirm the datasheet figures for 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.

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 case-packing line, pneumatic clamps and pushers often work best at a gentle, steady pressure well below main-line pressure. This low-pressure GR60020LC3T sits in the 3/4 inch drop to that clamp manifold and lets a technician dial in and hold the set point, reading it on the bar gauge.
Spray guns, air-assisted atomizers and blow-off nozzles need a calm, low regulated pressure to keep the pattern consistent. Fed from a filtered main, this size 600 regulator holds the low set point on a 3/4 inch feed line, with the round bar gauge giving the operator a direct visual reference during changeover.
Air flotation tables, air bearings under moving webs and low-pressure curtain jets on conveyor lines are easily disturbed by pressure swings. Mounted on the 3/4 inch branch feeding that section, this regulator keeps the cushion pressure steady, and the included bracket lets it be fixed beside the line controls.
Start with the port step: size 600 with 3/4 inch NPT threads is the largest GR frame, so match it to your main line diameter and required air demand; smaller sizes 200 to 400 cover lighter circuits. Decide between the standard type and this low-pressure type (L): if your process never needs more than 0.4 MPa downstream, the L version is the correct pick, while standard GR units set up to 0.9 MPa. Choose the gauge you want - this unit ships with a round bar-scale gauge, and square embedded gauges with MPa, psi or bar scales are available in the series. Thread is PT as the catalogue standard, with G (BSPP) and NPT as order options - this code specifies NPT. A mounting bracket is included as standard, and the body can also be panel-mounted. 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 GR regulator flow as performance curves rather than a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Tell us your line pressure, set pressure and expected air demand, and we will confirm the sizing from the datasheet curves before you order.
L marks the low-pressure type of the GR series. Where a standard GR sets up to 0.9 MPa, this low-pressure version regulates up to 0.4 MPa, which suits circuits that run at gentle pressures. Everything else decodes normally: size 600, 3/4 inch NPT ports, a round bar-scale gauge, and a mounting bracket included.
