The AirTAC GR60020LC2G 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 GR60020LC2G is an AirTAC GR-series air pressure regulator: it does one job, holding a stable downstream pressure from a compressed-air supply. This is the 600 size with a G3/4 (3/4 in) G-thread port, built as the low-pressure type, so the outlet can be set anywhere up to 0.4 MPa - suited to circuits that must never see full line pressure. The inlet side accepts up to 1.0 MPa (145 psi), and the fitted round gauge reads in psi so the setting is visible at the wall of the unit. As a pure regulator it has no filter bowl, no drain and no lubricator; it operates in -20 to 70 C, the widest temperature window in the G family.
This is a genuine AirTAC part. The GR line runs from size 200 to 600 with port sizes from 1/8 in to 1 in, in standard or low-pressure versions, with a choice of gauge scale (MPa, psi or bar), an optional reverse/check valve, PT as the standard thread and G or NPT as orderable options, and a mounting bracket included - the GR is also panel-mountable. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures against 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.

Vacuum-assisted clamps and hold-downs on carton-sealing or case-packing machinery need a supply that stays well below full line pressure. This low-pressure GR600 regulator caps the setting at 0.4 MPa and holds it steady, with the round psi gauge letting operators verify the clamp setting at a glance.
Air knives that blow droplets off bottles before labelling run on a controlled low-pressure air feed. The 3/4 in G-thread port suits the larger supply lines these stations use, and the regulator keeps the blowing pressure consistent so drying stays even along the conveyor.
Dilute-phase transfer of pellets or regrind from a silo to the process uses a regulated low-pressure air feed at the blower discharge. This GR600 unit on the supply line holds the conveying pressure stable through shift changes, and the -20 to 70 C range covers unheated plant areas.
Start with the port and size: the 600 body takes a 3/4 in connection, and the right step is the one that carries your circuit's air demand without choking it - we can check that against the published flow curves before you order. Then set the control band: this low-pressure (L) version adjusts up to 0.4 MPa, so choose it when the downstream device needs a gentle, capped supply; the standard GR type covers the wider range. The fitted round gauge here reads in psi; MPa and bar scales are the other options. Thread is G (BSPP) on this code, with PT as the catalogue standard and NPT available to order. A bracket is included, and the GR can also be panel-mounted. Because flow is published as curves, not a single rating, send us your air demand and we will confirm the sizing before you commit.
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 we do not quote one number. Tell us your line pressure, set pressure and air demand, and we will confirm the datasheet curves against your application on request before you order.
The L type limits the adjustable outlet to 0.4 MPa, which is the right choice when the downstream equipment must never be exposed to higher pressure - clamping, blowing and conveying circuits are typical. The standard GR type covers the wider adjustment range; both share the same 1.0 MPa maximum inlet and the same 600-size 3/4 in port.
