The AirTAC GFR20008F3TK AirTAC Filter Regulator NPT1/4 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 AirTAC GFR20008F3TK is a GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in one compact body. This size 200 unit is threaded NPT1/4 (1/4 in), carries the standard 40 um filter element, and uses a differential-pressure drain that bleeds accumulated condensate automatically whenever the pressure differential across the element is high enough - no daily manual draining on lightly loaded lines. The embedded square gauge is scaled in bar, and a reverse (check) valve is fitted so downstream pressure is held if the upstream supply is lost. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjustment range with this drain type is 0.15-0.9 MPa (20-130 psi), and the operating temperature is -5 to 70 C, non-freezing. The polycarbonate bowl suits the 200 frame; only the 600 size uses an aluminium alloy bowl.
This is a genuine AirTAC part. The GFR range spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, PT as the standard thread and G or NPT as order options, plus choices of drain type, 5 um filtration (code W), gauge scale and check valve. Flow for this series is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application on request.

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 clean, regulated air to a machining centre's tool-changer and clamping circuits: the 40 um element stops scale and pipe debris reaching the valves, the regulator holds a steady setpoint, and the check valve holds downstream pressure through brief supply dips.
A drop from the plant ring main to the pneumatic cylinders on a carton-forming conveyor: the differential-pressure drain keeps condensate moving out without operator attention, and the bar-scaled square gauge lets the line tech verify setpoint at a glance.
A 1/4 in bench drop at an assembly cell where operators run air tools and small actuators: one body filters the compressed air and regulates it to the working pressure, with the included bracket mounting the unit neatly on the station frame.
Start with the port step: this unit is NPT1/4 on the size 200 frame, the smallest GFR frame - step up to 300, 400 or 600 if your line needs more flow capacity. The differential-pressure drain fitted here suits steady duty; choose automatic drain (code A) for unattended or intermittent duty, or manual drain (code M) where you want positive control of blowdown - note the manual-drain variant also widens the regulation range down to 0.05 MPa. The standard element is 40 um; specify code W for 5 um if downstream equipment needs finer filtration. The square gauge here reads in bar; MPa and psi scales are available, and an external round gauge is an option. PT is the standard thread, with G (BSPP) and NPT orderable - this unit is the NPT version. A mounting bracket is included.
One honest note before you order: AirTAC publishes flow for this series as curves, not a single rated number, so send us your flow and pressure requirements and we will confirm sizing against the datasheet before you commit.
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 performance curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure, set pressure and air demand, and we will confirm the flow from the datasheet on request before you order.
The differential-pressure drain (the default) discharges condensate automatically when the pressure drop across the 40 um element rises, so it suits steady-running lines with no operator attention. If the unit sits on an intermittent or lightly loaded line where that differential rarely occurs, choose the automatic-drain version (code A); choose manual drain (code M) if you want controlled blowdown - the manual variant also extends the regulation range down to 0.05 MPa (7 psi).
