The AirTAC GR60020LJF2 AirTAC Air Pressure Regulator 3/4 in PT 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 GR60020LJF2 is a genuine AirTAC GR-series air pressure regulator: it does one job, holding a steady downstream pressure from your compressed-air supply, and it carries no filter element, bowl or lubricator. This unit is the low-pressure (L) type, so its setting range tops out at 0.4 MPa, and it is built in the largest GR size (600) with a 3/4 in PT port. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -20 to 70 C, and a square pressure gauge reading in psi is fitted as standard so operators can read and adjust the set point directly.
This is a genuine AirTAC part. The GR family runs from size 200 to 600 with port sizes from 1/8 in to 1 in, offered as standard or low-pressure types, with or without a gauge (MPa, psi or bar scales), with or without a mounting bracket, and in PT, G or NPT thread. Flow is published by AirTAC as curves rather than a single rated figure, so we confirm the datasheet and flow 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 carton-sealing or case-packing line, soft clamping and hold-down cylinders are run well below main-line pressure. This low-pressure regulator holds a gentle, repeatable set point so the clamp grips without crushing the product.
Bottle-rinsing and drying stations use air knives that need a calm, stable low-pressure supply rather than full line pressure. The regulator keeps the blow-off set point steady across the shift, and the fitted psi gauge lets an operator verify it at a glance.
Stopper gates, pushers and diverters on a conveyor line often run on low-pressure air to keep impacts soft. This 3/4 in regulator sits at the branch take-off and holds the gate circuit at its set point, with the psi gauge making checks part of routine walk-rounds.
Start with the port and size: this 600-size unit takes a 3/4 in PT port, the largest step in the GR range, so size up from 300/400 when the circuit's air demand is high. Then pick the type: this is the low-pressure (L) version, limited to settings up to 0.4 MPa - choose it only if your process never needs more; the standard GR covers 0.05-0.9 MPa. The fitted square gauge reads in psi; MPa and bar scales are alternatives. Thread is PT as standard, with G (BSPP) and NPT available as order options, and this J-coded unit comes without a mounting bracket (GR is also panel-mountable). Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering.
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 curves rather than a single rated number, so there is no one l/min or SCFM figure we can honestly quote. Send us your inlet pressure, set point and expected air demand, and we will confirm the flow figures from the datasheet for this exact model on request.
The L type is limited to settings up to 0.4 MPa, while the standard GR adjusts from 0.05 to 0.9 MPa. If your circuit always runs at or below 0.4 MPa, the low-pressure type suits it; if you may ever need a higher set point, order the standard type instead. Both share the same 1.0 MPa (145 psi) maximum inlet pressure.
