The AirTAC AirTAC GR60020F3TK Air Pressure Regulator 3/4 in NPT 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 GR60020F3TK is an AirTAC GR-series air pressure regulator: it does one job, holding downstream pressure steady at the value you set. This 600-size unit is the largest step in the GR range and is decoded with a 3/4 in NPT port, a setpoint range of 0.05-0.9 MPa (7-130 psi), and a maximum inlet pressure of 1.0 MPa (145 psi). The F3 suffix means a square pressure gauge is fitted and scaled in bar, the K suffix adds a reverse (check) valve so downstream pressure is held if the supply is lost, and the bracket is included for wall or machine mounting; GR bodies are also panel-mountable.
This is a genuine AirTAC part, sold by an authorised distributor for the US market. GR regulators are available in four sizes (200, 300, 400, 600) with ports from 1/8 in to 1 in, PT as the standard thread and G (BSPP) or NPT as order options, a low-pressure type (L) limited to 0.4 MPa, gauge scales in MPa, psi or bar, and an optional check valve. Flow is published as curves rather than a single rating, so ask us to confirm the 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.
| GR600 | G-series pressure regulator, 600 body — sets the port range. |

| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| (blank) | Standard type — 0.05 - 0.9 MPa (7 - 130 psi). Blank is standard, L is the low-pressure type. |
| (blank) | Fixing bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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 bench or C-frame pneumatic press, the GR60020F3TK sets and holds the working pressure that determines forming force, with the bar-scaled gauge giving the operator a direct setpoint readout and the check valve holding the setting if the shop air drops.
At a 3/4 in take-off from the main header in a plant compressor room, this 600-size regulator steps header pressure down to the level a downstream zone needs, protecting tools and actuators from full line pressure.
Feeding cylinders and air cylinders on a carton sealing or case-packing conveyor, the regulator keeps actuator speed consistent by holding a fixed downstream pressure, while the check valve prevents backflow surprises during supply dips.
Start with the port step: 600 is the largest GR size and takes a 3/4 in port, so size up from a 300 or 400 only where your line genuinely needs the larger flow path - we can check the published flow curves against your demand. The setpoint range here is 0.05-0.9 MPa (7-130 psi); if you need to regulate below that, ask about the low-pressure L type (up to 0.4 MPa). This unit ships as decoded with a bar-scaled square gauge, a reverse/check valve (K) and the mounting bracket; a no-gauge (N) version or an external round gauge are alternatives in the range. Thread is NPT on this code; PT is the catalogue standard and G (BSPP) can be ordered instead. Because flow is published as curves, not a single rating, send us your required flow and pressure 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 GR regulator flow as curves, not as a single rated number, so we do not quote a figure. Send us your inlet pressure, set pressure and required flow and we will confirm sizing against the datasheet curves on request before you order.
F3 means a square pressure gauge is fitted with its scale in bar (MPa and psi scales are available as other codes). K means a reverse/check valve is fitted, which holds downstream pressure if the upstream supply is interrupted. The bracket is included as standard on this code.
