The AirTAC GR60020C2TK 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 GR60020C2TK is an AirTAC GR-series air pressure regulator in the largest 600 size, fitted with a 3/4 in NPT port. It does one job only: reducing and holding a stable downstream pressure from a compressed-air supply, adjustable across 0.05-0.9 MPa (7-130 psi). This configuration carries an external round pressure gauge scaled in psi, a built-in reverse (check) valve that lets downstream air hold when upstream pressure is lost, and a mounting bracket; the GR body is also panel-mountable. Maximum working (inlet) pressure is 1.0 MPa (145 psi), and the GR is rated for ambient temperatures from -20 to 70 C, wider than the rest of the G family.
This is a genuine AirTAC part. The GR line spans sizes 200 to 600 with port sizes from 1/8 in to 1 in, in standard and low-pressure types, with gauge, thread and check-valve options to order. Flow for this series is published as curves rather than a single rated figure, so ask us and we will confirm the 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 a 3/4 in plant air header down to a stable working pressure for a production cell, with the psi gauge giving operators a direct local reading and the check valve holding the cell's setting if the main is shut off.
Feeding a bank of air-operated valves or cylinders that need a fixed, repeatable supply pressure; the regulator holds the setpoint across 0.05-0.9 MPa so actuator sequencing stays consistent shift after shift.
A regulation station on a new or retrofitted machine's air preparation panel: bracket or panel mounting, 3/4 in NPT plumbing, and a check valve that keeps the circuit pressurised during brief upstream interruptions.
Sizing a GR60020C2TK starts with the port and flow step: the 600 size with a 3/4 in NPT port is the largest step in the GR range, chosen when the line size and air demand are at the top of the family. Set the working band from the decoded range of 0.05-0.9 MPa (7-130 psi) against what your downstream equipment actually needs. The gauge here is the external round type scaled in psi; MPa or bar scales and the embedded square gauge are the other decodable choices. The trailing K confirms a reverse (check) valve is fitted, and the bracket is included, with panel mounting also possible on GR. Thread is NPT on this code; PT is the standard thread and G (BSPP) is the alternative order option. One honest note before you order: flow for this series is published as curves, not a single rating, so send us your application and we will confirm sizing against the datasheet before you commit.
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 GR-series flow as curves, not as a single rated number, so there is no one figure we can honestly quote. Send us your line conditions and required downstream pressure and we will confirm the relevant datasheet flow figures for this 3/4 in, 600-size regulator on request.
K is the reverse (check) valve option, and on GR60020C2TK it is fitted. It allows air to flow back from the downstream side, so the regulated circuit holds its pressure if the upstream supply drops or is isolated. The same regulator without K blocks reverse flow; it is a real decode choice when you order.
