The AirTAC GR60020LJF2G AirTAC Air 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 GR60020LJF2G is an AirTAC GR-series air pressure regulator: it does one job, holding a steady downstream air pressure, and nothing else. This is the 600 size with 3/4 in ports in G (BSPP) thread, built as the low-pressure type with an adjustment range up to 0.4 MPa, so it suits circuits that must never be driven to full line pressure. A square pressure gauge reading in psi is fitted so the setting can be read directly at the unit, and no mounting bracket is included, though the GR body is also panel-mountable. As a pure regulator it has no filter bowl and no drain.
This is a genuine AirTAC part. The GR family spans the 200, 300, 400 and 600 sizes with port sizes from 1/8 in to 1 in, in standard and low-pressure types, with gauge scale and thread options to order. Flow figures for the GR600 are published as curves rather than a single rating, 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.

On a bottling or canning line, the pneumatic capping and clamping cylinders are often specified to run well below main header pressure. This low-pressure GR600 regulator holds their supply at a safe setting up to 0.4 MPa, with the fitted psi gauge letting a line technician read and lock the setting at the machine.
Air knives and blow-off nozzles that clear crumbs, dust or rinse water from a food-grade conveyor need steady, gentle air rather than full line pressure. This 3/4 in low-pressure regulator keeps their feed within the 0.4 MPa ceiling, and its larger ports suit the higher air draw of wide air-knife manifolds.
A lab drying rack that pushes air through beakers and flasks needs a mild, consistent supply so delicate glassware is not blasted. Fed from the compressed-air header through this GR600 regulator, the rack runs at a controlled low pressure, with the square psi gauge making the setting visible and repeatable.
Start with the port step: the 600 size carries 3/4 in ports, the largest in the GR range, so pick it when the circuit's pipe and expected air demand sit at that level; the smaller 200/300/400 sizes cover lighter duties. Choose the low-pressure (L) type only when the downstream equipment must be limited to 0.4 MPa or less; the standard type covers the full 0.05-0.9 MPa range. This unit ships with a square gauge reading psi; MPa and bar scales are available as codes. Thread is G (BSPP) here, while PT is the catalogue standard and NPT is an order option - match it to your fittings. No mounting bracket is fitted (J code); order a bracketed variant if you need one. Flow for the GR600 is published as curves, not a single rating, so send us your application details and we will confirm sizing from 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 GR600 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 the air demand of your equipment, and we will confirm the sizing against the datasheet curves for you before you order.
The L in the code marks the low-pressure type: its adjustment range tops out at 0.4 MPa, instead of the 0.05-0.9 MPa of the standard GR. That protects downstream equipment that must not see full line pressure. The F2 code means a square pressure gauge is fitted with a psi scale; MPa and bar scales are available as alternative codes, and an external round gauge is an option.
