The AirTAC GFR20008JC1WT 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 GFR20008JC1WT is a size-200 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 1/4 in NPT port, a 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and a round pressure gauge scaled in MPa. The polycarbonate bowl lets you see the condensate level at a glance, and the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, thread options PT, G and NPT, manual, automatic or differential-pressure drains, 40 um or 5 um elements, and gauge choices. Flow figures for this model are published as curves rather than a single rating, so ask us to confirm the datasheet figures 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.

Feeds filtered, regulated air to a machining-centre clamping circuit, where the 5 um element protects the clamp cylinders and the round gauge lets the setter verify clamping pressure at a glance.
Sits upstream of conveyor stopper and pusher cylinders on a packaging line, cleaning the air supply and holding a steady working pressure so divert operations stay repeatable through the shift.
Conditions the compressed air feeding bench-top lab equipment and pneumatic sample-handling fixtures, where the 5 um grade and visible condensate bowl suit a clean, low-duty environment.
Size and port step up together: 200 is the compact end of the GFR range with a 1/4 in port here, so match the size to the air demand of the circuit rather than oversizing on instinct. This unit is ordered with a 5 um element (code W) instead of the standard 40 um - choose 5 um where downstream valves, cylinders or instruments need cleaner air, and 40 um where general water and chip removal is enough. The differential-pressure drain (the default) needs no timer or operator attention, but a manual or automatic drain can be specified instead. The round MPa gauge fitted here can alternatively be ordered as the embedded square gauge, or with psi or bar scales. Thread is NPT on this code; PT and G are catalogue options. No mounting bracket is included with the J code.
Flow for the GFR series is published as curves, not a single rated figure, so we do not quote a number here. 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves rather than a single rated figure, so we do not quote a number here. Tell us your application and air demand and we will confirm the sizing against the datasheet on request before you order.
The W in the code GFR20008JC1WT selects the optional 5 um filter grade; the catalogue standard is 40 um. Choose 5 um when downstream valves, cylinders or instruments need finer filtration, and 40 um for general water and particulate removal. Both grades are available across the GFR range.
