The AirTAC GR60020JF3T 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 - 0.9 MPa (7 - 130 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 GR60020JF3T is an AirTAC GR-series air pressure regulator: it does one job, holding your downstream pressure steady at the value you set, and it carries no filter, no bowl and no lubricator. This is the size-600 unit, the largest in the GR range, with a 3/4 in NPT port for high-flow compressed-air lines. The standard regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi), and it is rated for -20 to 70 C, the widest temperature window in the G family. The F3 suffix means a square pressure gauge is fitted, reading in bar, embedded in the body; an external round gauge is available as an option. No mounting bracket is supplied with this code, and no reverse/check valve is fitted.
This is a genuine AirTAC part. The GR series spans sizes 200 to 600 with ports from 1/8 in to 1 in, and options include G (BSPP) or NPT threads, a low-pressure type limited to 0.4 MPa, a reverse/check valve, and panel mounting. We do not publish a single rated-flow figure because AirTAC publishes flow as curves; ask us and we will confirm the flow and datasheet figures for your application on request.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.

Dropping the 3/4 in distribution header down to a controlled working pressure so every drop and branch on the shop floor sees a stable, repeatable supply.
Setting and holding the clamping or forming pressure on a pneumatic press cell, where a steady setpoint keeps part hold-down force consistent across shifts.
Feeding cylinders, grippers and diverters on a packaging or bottling conveyor line from a regulated branch, so actuator speed and seating stay predictable.
Start with the port step: GR sizes run 200 to 600 with ports from 1/8 in up to 1 in, and this GR600 unit sits at the top with a 3/4 in NPT port, so size up to it when your line flow demand is at the high end. Set the gauge to match your team: this code carries the square gauge with a bar scale, and MPa or psi scales can be ordered instead. Choose the thread deliberately: PT is the standard, while G (BSPP) and NPT are catalogue options you specify at ordering - this code is the NPT version. Decide on the extras: the J code here means no mounting bracket (a bracket is optional, and GR is also panel-mountable), the low-pressure L type caps adjustment at 0.4 MPa if your process needs it, and a K suffix adds a reverse/check valve. One honest routing note: AirTAC publishes regulator flow as curves, not a single rating, so send us your line pressure, set pressure and demand 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 curves rather than a single rated number, so we do not quote a flow figure here. Send us your inlet pressure, set pressure and air demand, and we will confirm the flow from the datasheet for your application on request.
The F3 code on GR60020JF3T means an embedded square gauge with a bar scale is fitted as standard. MPa and psi scales are catalogue options, and an external round gauge is available instead of the embedded square gauge if you prefer - just specify the scale when ordering.
