The AirTAC GR20008F2TK 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 AirTAC GR20008F2TK is a GR-series air pressure regulator: it does one job, holding a steady downstream pressure from a compressed-air supply, and it carries no filter, no bowl and no lubricator. This 200-size unit is threaded NPT1/4 (1/4 in), is the standard (not low-pressure) type, and adjusts from 0.05 to 0.9 MPa (7-130 psi). The embedded square gauge reads in psi, an external round gauge is available as an option, and a reverse/check valve is fitted so downstream pressure is held if the upstream supply drops. A mounting bracket is included, and the GR body is also panel-mountable.
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 (BSPP) or NPT thread, with gauge scale, low-pressure type, check valve and bracket as orderable options. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -20 to 70 C, wider than the rest of the G family. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures 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.

Set and hold a repeatable downstream pressure for a small pneumatic press or clamping fixture, with the square psi gauge giving a direct readout at the setpoint.
Regulate the supply pressure feeding cylinders and actuators on a packaging line, with the fitted check valve holding the setting if the main supply dips.
Trim the pressure to conveyor stoppers and diverters so actuator speed and impact stay consistent along the line, using the included bracket for local mounting.
Pick the GR size by the port and flow step you need: 200 with a 1/4 in port sits at the compact end of the 200/300/400/600 range, and larger sizes carry larger ports and more flow. Decide the gauge scale you want to read - MPa, psi (this unit) or bar - and whether the embedded square gauge or the optional external round gauge suits your panel. Choose the thread for your piping: PT is the standard, with G (BSPP) and NPT (this unit) as catalogue options to order. Add the K option if you want the reverse/check valve fitted, the L suffix only if your circuit runs at low pressure (up to 0.4 MPa), and specify J if you do not want the bracket. Flow for this family is published as curves, not a single rated figure, so send us your application details 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 regulator flow as curves, not as a single rated number, so we do not quote a flow figure. Tell us your application and we will confirm the datasheet flow curve and sizing for this 200-size, 1/4 in unit on request.
The K means a reverse/check valve is fitted, so downstream pressure is held if the upstream supply is lost. The T means the port is NPT 1/4 in; PT is the standard thread for the GR series, with G (BSPP) and NPT available as order options.
