The AirTAC GR20006JF1TK AirTAC Air Pressure Regulator NPT1/8 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 PT1/8" 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 GR20006JF1TK is an AirTAC GR-series air pressure regulator for compressed air only. It does one job: it holds a stable downstream pressure set anywhere in its 0.05-0.9 MPa (7-130 psi) adjustment range, with a maximum inlet pressure of 1.0 MPa (145 psi). This unit is the size 200 body with a 1/8 in NPT port, and the code tells you exactly how it is built: a square pressure gauge scaled in MPa is fitted as standard, a reverse/check valve is fitted so downstream pressure is held if the supply drops, and no mounting bracket is included - the GR body is also panel-mountable. It contains no filter and no bowl; it is regulation only.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, in PT (standard), G and NPT threads, with optional low-pressure type, gauge scale in MPa, psi or bar, and reverse/check valve. Operating temperature is -20 to 70 C, wider than the rest of the G-series. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application.

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.

A dedicated regulator on the clamp circuit of a CNC fixture holds a fixed clamping pressure independent of shop-air swings, so every part is gripped at the same set point. The check valve keeps the clamps from relaxing if the main supply dips mid-cycle.
Compact grippers and small cylinders on an assembly cell need a gentle, stable supply pressure to avoid slamming parts. A 1/8 in regulator set low in its range gives that fine control at the point of use, right at the cell drop.
Lab rigs and test benches often run instruments and small air actuators at pressures well below the main line. A panel-mounted GR regulator lets the operator dial in and hold the exact test pressure, with the MPa gauge giving a direct readout.
Start with the port: this unit is 1/8 in NPT. If your line runs larger, step up to a GR300, GR400 or GR600 - bigger size means bigger port and more flow capacity, so match the size to the flow your circuit needs rather than to the pipe alone. Set-point range is 0.05-0.9 MPa (7-130 psi) on this standard type; if your working pressure stays below 0.4 MPa, the GR low-pressure type (code L) gives finer control at the bottom of the range. Choose the gauge scale you read in - MPa (this unit), psi or bar - and decide whether you want the reverse/check valve (fitted here) to hold downstream pressure on supply loss.
Thread is a real order decision: PT is the AirTAC standard, while G (BSPP) and NPT (this unit) are catalogue options you select in the code. Brackets are optional on GR (this unit ships without one) and the body can be panel-mounted instead. One honest note on sizing: flow data is published as pressure-loss curves, not a single rated number, so send us your flow and pressure targets and we will confirm the right size 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 pressure-loss curves rather than a single rated figure, so we do not quote a Cv, l/min or SCFM number. Send us your required flow and upstream/downstream pressures and we will confirm the correct size and the datasheet figures for your application on request.
F is the square embedded pressure gauge and the 1 sets its scale to MPa (psi and bar scales are available as options). K means a reverse/check valve is fitted, which holds downstream pressure if the upstream supply is lost. The J earlier in the code means no mounting bracket is included; the GR body can also be panel-mounted.
