The AirTAC GR60020F2TK AirTAC Air Pressure Regulator NPT 3/4 in 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 GR60020F2TK is an AirTAC GR-series air pressure regulator for compressed air only. It does one job - holding a steady downstream pressure - and contains no filter, no bowl and no drain. This 600-size unit is decodes to a 3/4 in NPT port, the largest port step in the G series, and carries the standard regulation range of 0.05-0.9 MPa (7-130 psi). The F2 code means an embedded square pressure gauge scaled in psi is fitted, and the K code adds a reverse (check) valve so downstream pressure cannot push back through the regulator.
This is a genuine AirTAC part. The GR family spans 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, optional G (BSPP) or NPT threads in place of the PT standard, low-pressure variants, gauge scale choices and a check-valve option. Flow 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.

| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |

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.

Size the GR by port step against the air demand of the circuit: 200 through 600 cover 1/8 in to 1 in, and the 600 size with its 3/4 in port suits the heavier end of that range. Because flow is published as curves and not a single rating, ask us to confirm sizing against your application before ordering. Other real choices on this family: gauge scale (MPa, psi or bar - this unit ships with a square psi gauge, and an external round gauge is available), thread (PT is the standard; G/BSPP and NPT are order options, and this unit is NPT), the reverse/check valve (fitted here, code K), and the mounting bracket, which is included on GR units - the GR is also panel-mountable. Temperature range for GR is -20 to 70 C, wider than the rest of the G family.
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 flow as curves rather than a single rated figure, so there is no one number we can honestly quote. Tell us your supply pressure and the air demand of the circuit, and we will confirm the datasheet flow curve figures for this 600-size, 3/4 in NPT unit on request before you order.
F means the embedded square pressure gauge is fitted, 2 means that gauge is scaled in psi (MPa and bar scales are also available), T means the port thread is NPT rather than the PT standard, and K means a reverse (check) valve is fitted so downstream pressure cannot back-feed through the regulator.
