The AirTAC GR20006LF2K AirTAC Low-Pressure Regulator, PT1/8 is a genuine G-series air pressure regulator. It holds a stable downstream pressure over the range 0.05 - 0.4 MPa (7 - 58 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 GR20006LF2K is an AirTAC GR-series air pressure regulator: it does one job, holding a stable downstream pressure from your compressed-air supply. This is the low-pressure (L) type, so the outlet pressure is adjustable up to 0.4 MPa, and it is built in the compact GR200 size with a PT1/8 (1/8 in) port. The code also tells you it ships as a regulator only - there is no filter, no bowl and no drain on this unit - with a square pressure gauge fitted on a psi scale and a reverse (check) valve (K) so downstream air cannot push back through the regulator when the supply drops. A mounting bracket is included, and the GR body also accepts panel mounting. Operating temperature is -20 to 70 C, wider than the rest of the G family, with a maximum inlet pressure of 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GR line runs from size 200 up to 600, with larger port sizes, standard or low-pressure regulation, square or round gauges in MPa, psi or bar scales, an optional reverse valve, and PT, G or NPT threads. Flow for this regulator is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures against your application before you order.

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.

On a packaging or assembly machine, feed the pilot ports of directional valves from a branch set well below main line pressure. The low-pressure type caps the setting at 0.4 MPa, and the check valve holds the pilot signal if supply pressure dips.
On a bench rig or small test station, use the psi-scaled square gauge to set a repeatable low outlet pressure for instruments, small actuators or air bearings, with the reverse valve protecting the bench circuit from backflow.
Tap a 1/8 in take-off from the main FRL set to feed sensors, air jets or small cylinders that need their own gentler setting, panel- or bracket-mounted right at the point of use.
Pick the GR size by the port and flow step you need - this GR200 takes a 1/8 in port, and the range steps up through 300, 400 and 600 for larger ports and higher flow demand. Choose the low-pressure (L) type only when your setting must stay at or below 0.4 MPa; the standard GR covers 0.05-0.9 MPa. This unit has the square gauge on a psi scale (code F2); round gauges and MPa or bar scales are the other catalogue options. The K code means a reverse (check) valve is fitted - drop it from the code if you do not want backflow protection. Thread is PT as the standard; order G (BSPP) or NPT instead if your piping needs it, and a bracket is included (J removes it). One honest note: AirTAC publishes flow as curves, not a single rated number, so send us your line conditions and we will confirm sizing from 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 regulator flow as curves rather than a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Tell us your inlet pressure, set pressure and expected consumption, and we will confirm the flow from the GR200 datasheet for your exact condition before you order.
The L in the code makes this the low-pressure type: the outlet pressure is adjustable up to 0.4 MPa instead of the standard GR range of 0.05-0.9 MPa, so it suits circuits that must never see full line pressure. The trailing K means a reverse (check) valve is fitted, so downstream air cannot flow back through the regulator when the upstream supply is lost. Both are catalogue options - order the plain code for standard range without the valve.
