The AirTAC GR20008F3TK AirTAC Air Pressure Regulator NPT1/4 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 PT1/4" 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 GR20008F3TK is an AirTAC GR-series air pressure regulator for compressed air, and this configuration is a size 200 unit with a 1/4 in NPT port. It is the standard (non low-pressure) type with an adjustment range of 0.05-0.9 MPa (7-130 psi), a maximum inlet pressure of 1.0 MPa (145 psi), and an operating temperature range of -20 to 70 C. The embedded square pressure gauge with bar scale is fitted as coded, a reverse/check valve is fitted (code K), and a mounting bracket is included; the GR family is also panel-mountable.
This is a genuine AirTAC part. The GR line spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options include G (BSPP) or NPT threads in place of the PT standard, MPa, psi or bar gauge scales, an external round gauge, a low-pressure type limited to 0.4 MPa, and a reverse/check valve. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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.

| (blank) | Standard type — 0.05 - 0.9 MPa (7 - 130 psi). Blank is standard, L is the low-pressure type. |

| F | Gauge shape: Square. C is round, F is square. |
| 3 | Gauge scale: bar. 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.

Set and hold the downstream pressure feeding clamp cylinders on a milling or drilling fixture, with the check valve helping hold the set circuit condition if upstream supply dips.
Regulate the pressure feeding pick-and-place and sealing cylinders on a packaging line, with the bar-scale gauge letting an operator read the setpoint at the machine.
Supply divertors, stoppers and pushers along a conveyor line at a stable, adjustable pressure, using the included bracket to mount the regulator beside the manifold.
Pick the GR size by the port and flow your line needs: size 200 with a 1/4 in port suits compact circuits, while sizes 300, 400 and 600 step up in port and flow capacity. Choose the gauge scale you read in - MPa, psi or bar - and the square embedded gauge is standard, with an external round gauge available. Set downstream pressure anywhere in the 0.05-0.9 MPa (7-130 psi) range; if your circuit runs at low pressure only, the L-type variant is limited to 0.4 MPa. Thread is PT as standard, with G (BSPP) and NPT as orderable options - this model is coded NPT. The K code adds a reverse/check valve, and a mounting bracket is included.
Because AirTAC publishes regulator flow as curves rather than a single rated number, ask us to confirm sizing against your application before ordering.
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 rather than a single rated figure, so no rated flow number is stated here. Ask us and we will confirm the datasheet flow curve and sizing for the GR200 at your operating conditions before you order.
K means a reverse/check valve is fitted on this unit. The F3 code means the embedded square gauge with a bar scale is included; MPa and psi scales and an external round gauge are available as orderable options, and the pressure adjustment range is 0.05-0.9 MPa (7-130 psi).
