The AirTAC GFR20008F2TK AirTAC Filter Regulator NPT1/4 with Gauge is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1/4" ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR20008F2TK is an AirTAC GFR200 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in one compact body. This configuration has a 1/4 in NPT port, a 40 um standard filter element, a differential-pressure drain (the standard drain type for the series), a built-in reverse (check) valve, and an embedded square gauge reading in psi. The polycarbonate bowl lets you see the condensate level, the regulator adjusts across 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and with options for manual or automatic drains, a 5 um filter element (code W), MPa, psi or bar gauge scales, an external round gauge, and G (BSPP) or NPT threads in place of the PT standard. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet numbers for your application.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). Air must not freeze in the unit. 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, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no 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. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Feeding directional control valves on a packaging or assembly machine: the 40 um element strips water and swarf before they reach the valve seats, while the regulator holds a steady supply pressure so valve shift behaviour stays repeatable through the shift.
Supplying power clamps and fixture cylinders on a CNC cell: the regulator pins the clamping pressure at the setpoint, the check valve holds the downstream circuit if upstream pressure dips, and the psi gauge gives the operator a direct readout at the machine.
Feeding air cylinders and gripper actuators along a conveyor line: filtered, regulated air at the point of use protects the actuators from condensate carryover, and the differential-pressure drain keeps the bowl cleared without a manual drain routine at each drop.
Size the unit by port and flow: GFR200 carries a 1/4 in port and sits at the smaller end of the range, stepping up through GFR300 (3/8-1/2 in), GFR400 (3/4 in) and GFR600 (1 in) as air demand grows. Choose the drain: differential-pressure (this unit, the standard), automatic (code A) or manual (code M). Filter grade is 40 um standard; specify W for 5 um where finer filtration is needed. The square gauge on this unit reads psi; MPa and bar scales are catalogue options, and an external round gauge is also available. Thread here is NPT; PT is the standard and G (BSPP) is orderable. A mounting bracket is included with this size. Flow for the series is published as curves, not a single rating, so send us your application details and we will confirm sizing against the datasheet before you order.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves, not as a single rated figure, so we do not quote a l/min or SCFM number. Tell us your application and required downstream pressure and we will confirm the sizing against the datasheet curves before you order.
F2 means this unit carries the embedded square gauge with a psi scale. The catalogue also offers MPa (code 1) and bar (code 3) scales, and an external round gauge is available as an option if you prefer that style at the panel.
