The AirTAC GFR20006C2WTK AirTAC Filter Regulator NPT1/8 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 PT1/8" 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 GFR20006C2WTK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single compact body. This 200-size unit is threaded NPT1/8, carries a fine 5 um filter element (the tighter of the two catalogue grades), drains condensate automatically via the differential-pressure principle, and is fitted with an external round gauge scaled in psi plus a reverse/check valve that holds downstream pressure if the upstream supply drops.
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, a choice of drain type, 40 um or 5 um filtration, gauge style and scale, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application before ordering.

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 pneumatic tool-change and clamping circuits, where the 5 um element protects precision valves and the check valve holds pressure if the shop supply dips.
Conditioning the air feeding conveyor stopper and diverting cylinders on a packaging line, with the psi gauge letting operators set and verify the working pressure at the machine.
Supplying filtered, regulated air to lab analysers or test rigs, where the fine 5 um grade and compact 1/8-inch port suit small point-of-use instruments.
Sizing starts with the port: this unit is NPT1/8 on the 200-size body, so step up to a 300/400/600 GFR if your line needs a larger port and more flow. The 5 um element here suits air tools, instrumentation and valves that want cleaner air than the standard 40 um grade; choose 40 um where coarser protection is enough. Drain choice matters: differential-pressure (as coded here) drains only when the pressure differential allows it, automatic drains unattended, and manual drains need a routine bleed. The round psi gauge matches US-style reading; square gauges and MPa or bar scales are alternatives. PT is the standard thread and G or NPT are ordered options - this unit is the NPT version. A bracket is included for panel or wall fixing.
Because flow is published as curves and not a single rated figure, send us your application details and we will confirm the right size 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 number, so we do not quote a figure that could mislead. Send us your application details and we will confirm the flow and datasheet figures for this exact 200-size, NPT1/8 unit on request before you order.
K means a reverse (check) valve is fitted, so downstream pressure is held if the upstream supply is lost. This unit's drain is the differential-pressure type (no drain letter in the code): condensate is discharged automatically when the pressure differential allows it. Automatic (A) and manual (M) drains are catalogue alternatives if you prefer a different drain behaviour.
