The AirTAC GFR20008JF1WTK AirTAC Filter Regulator NPT1/4 5 um is a genuine G-series filter regulator: water separation, 5 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 GFR20008JF1WTK is a size-200 filter regulator: it removes water and particulate from compressed air and sets a stable downstream pressure in one compact body. This configuration carries a 1/4 in NPT port, a fine 5 um filter element, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, an embedded square pressure gauge scaled in MPa, and a built-in reverse (check) valve that holds the downstream setting when upstream supply is lost. It ships without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range is 0.15-0.9 MPa (20-130 psi), the polycarbonate bowl suits non-freezing compressed air from -5 to 70 C.
This is a genuine AirTAC part from the GFR series, published in sizes 200 through 600 with ports from 1/8 to 1 in. Across the series you can order manual or automatic drains instead of the differential-pressure type, a 40 um standard element instead of 5 um, gauge scales in MPa, psi or bar, PT (standard), G or NPT threads, and bracket options. Rated flow is published as curves rather than a single figure, so we confirm the datasheet and sizing figures 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.

Feeds filtered, regulated air to the tool-clamp and tool-change cylinders on a CNC machining center, where the 5 um element protects the clamping valve stack and the check valve holds clamp pressure through a supply dip.
Supplies the stopper, pusher and guide cylinders along a bottling or canning conveyor, keeping the line pressure set steady shift after shift while the differential-pressure drain clears condensate in continuous flow.
Conditions the air feed to pneumatic torque tools and press fittings at an assembly bench, dropping shop air to the tool circuit's working pressure and straining pipe scale and water before it reaches the tools.
Size and port are the first choice: step up from 200 to 300, 400 or 600 when the circuit needs a larger port and more flow, matching the 1/4 in NPT connection here to your piping. Choose the drain to suit attendance: differential-pressure (this unit) needs no attention in steady flow, automatic drains continuously, and manual drain suits intermittent lines with an operator on site. Filter grade is 40 um standard or 5 um fine (this unit, code W) for sensitive valves and cylinders. Gauge scale is MPa, psi or bar, embedded square or optional external round. Thread is PT as standard with G and NPT as order options, and a bracket can be added where this no-bracket unit needs panel fixing. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering.
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 the flow your circuit needs, and we will confirm the sizing from the datasheet curves on request before you order.
The W in the code selects the optional 5 um fine element in place of the 40 um standard. Choose 5 um where downstream pilot valves, precision cylinders or instruments are sensitive to fine particulate; 40 um is sufficient for general plant air. Both grades are available across the GFR series, and the differential-pressure drain works with either.
