The AirTAC GR20008F1TK AirTAC Air Pressure Regulator 1/4 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 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 GR20008F1TK is a genuine AirTAC GR-series air pressure regulator in the compact size 200 body, built for 1/4 in NPT ports and used to hold a steady downstream pressure from a compressed-air supply. It regulates from 0.05 to 0.9 MPa (7-130 psi), carries a maximum inlet pressure of 1.0 MPa (145 psi), and operates from -20 to 70 C - the widest temperature window in the G family. This configuration comes with an embedded square gauge scaled in MPa, a built-in reverse (check) valve so downstream pressure is held if the upstream supply drops, and a mounting bracket fitted as standard.
GR200 is the smallest step in the GR range, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in and PT, G or NPT threads. This unit is regulation only: it contains no filter, no bowl and no drain, so pair it with a GF filter upstream if the line needs water and particulate removal. Because AirTAC publishes regulator flow as curves rather than a single rated figure, we confirm the flow and datasheet details 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.

Set a stable clamping pressure on a workholding fixture or small pneumatic press fed from a 1/4 in NPT drop, with the check valve holding the set pressure if the main supply dips mid-cycle.
Regulate the air to diverters, pushers and seal cylinders on a packaging conveyor branch, keeping setpoint steady at the machine even as upstream demand fluctuates.
Give a bench-top test rig or laboratory apparatus a repeatable, manually adjustable supply pressure from a 1/4 in NPT line, with the -20 to 70 C range suiting unheated rooms and cold stores.
Start with the port and flow demand: size 200 with 1/4 in NPT ports suits compact branch lines and individual actuators; step up to GR300, GR400 or GR600 as required flow and pipe size grow. Set the working band against the 0.05-0.9 MPa (7-130 psi) adjustment range and the 1.0 MPa (145 psi) maximum inlet. This code carries a square gauge scaled in MPa; psi or bar scales and an external round gauge are order options if you prefer a different readout. The trailing T fixes NPT threads, while PT (standard) and G are available to order, and the K in the code means a reverse/check valve is already fitted - useful where a held downstream pressure matters. GR is also panel-mountable, and a bracket is included here. For sizing, ask us to confirm flow against the published curves before ordering, since no single rated flow figure applies.
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 performance curves rather than a single rated figure, so no one number applies. Send us your line pressure, set pressure and expected air demand, and we will confirm the flow from the datasheet curves for this exact model before you order.
K means a reverse (check) valve is fitted. If upstream pressure falls or is shut off, the valve helps hold the regulated downstream pressure instead of letting it bleed back through the regulator - useful on clamp circuits or any actuator that must not lose its setpoint mid-cycle.
