The AirTAC GR60020F2K AirTAC Air Pressure Regulator PT3/4 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 GR60020F2K is an AirTAC GR-series air pressure regulator for compressed air, providing pressure regulation only - no filtration and no lubrication. This 600-size unit has PT3/4 (3/4 in) ports with PT thread as standard, and the K code means a reverse (check) valve is fitted so downstream pressure is held if the upstream supply drops. The F2 code gives the embedded square pressure gauge with a psi scale, and the standard adjustment range is 0.05-0.9 MPa (7-130 psi) against a maximum inlet pressure of 1.0 MPa (145 psi). Operating temperature is -20 to 70 C, wider than the rest of the G family.
This is a genuine AirTAC part. The GR series is available in sizes 200, 300, 400 and 600 with a choice of thread (PT standard, G and NPT to order), gauge scale (MPa, psi or bar), an optional external round gauge, a low-pressure type (L), a reverse/check valve, and bracket or panel mounting. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures for your application before ordering.

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.

Set and hold a stable working pressure to a 3/4-in pneumatic press circuit, with the check valve holding the set pressure at the press if the main supply is interrupted.
Installed at a 3/4-in branch take-off from a factory air main, the regulator drops main-line pressure to the level each downstream cell or machine needs.
Feeds cylinder and actuator circuits on packaging machinery, letting maintenance set the working pressure locally and read it on the psi-scale gauge.
Size and port are the first choice: the 600 size carries the largest ports in the GR range, and this unit is decoded at PT3/4 - match the port step to the pipe size and required flow of the line. Set the outlet pressure within the 0.05-0.9 MPa (7-130 psi) standard range; if your circuit runs below that, ask about the low-pressure (L) type. Choose the gauge scale you want to read: this code carries the embedded square gauge in psi, with MPa or bar scales and an external round gauge available as options. The K code adds a reverse/check valve - useful where downstream pressure must be retained on supply loss; omit it if not needed. Thread is PT as standard with G (BSPP) and NPT as orderable options, and the unit is supplied with a mounting bracket and 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
The reflux valve lets air flow back through the regulator, which is useful when downstream volume must vent quickly. A regulator does not remove water or particulate; that is the filter's job.
AirTAC publishes regulator flow as curves, not as a single rated figure, so we do not quote a number here. Tell us your line size, inlet pressure and set pressure, and we will confirm the flow from the datasheet curves for your application before you order.
K means a reverse (check) valve is fitted, so downstream pressure is retained if upstream supply is lost. F2 means the embedded square gauge is fitted with a psi scale; MPa or bar scales, and an external round gauge, are available as order options.
