The AirTAC GFR20006F2WTK 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 GFR20006F2WTK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one compact body. This size 200 unit has a 1/8 in NPT port, a 5 um filter element for finer filtration than the standard 40 um grade, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, a built-in reverse/check valve that holds downstream pressure when the supply is lost, and an embedded square gauge reading in psi. Outlet pressure is adjustable from 0.15 to 0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature range of -5 to 70 C (non-freezing). The polycarbonate bowl is standard at this size.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and with options including manual or automatic drains, a 5 um element, different gauge scales, G (BSPP) or NPT threads and bracket variations. Flow is published as curves rather than a single rated figure, so we 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.

Supplying clean, regulated air to pneumatic clamps on a machining-centre fixture, where the 5 um element protects the clamp valve and the check valve holds clamping pressure if shop air drops.
Feeding diverters, stop gates and pusher cylinders on a packaging conveyor, with the regulator set to the cylinder rating and the differential-pressure drain keeping condensate off the valves during continuous runs.
Providing filtered, pressure-controlled air to a pneumatic actuator on a process line, where the square psi gauge gives operators a direct local reading and the check valve maintains actuator position on air failure.
Start with the port and size step: GFR200 with a 1/8 in NPT port suits compact circuits, while GFR300/400/600 cover larger ports and higher air demand - match the step to the flow your line needs, and we will confirm sizing against the published flow curves before you order. Choose the drain: differential-pressure (this unit) bleeds condensate as air flows, automatic drains on a timer-independent basis, and manual drains for periodic emptying. Choose the element grade: 40 um standard or 5 um (code W, as fitted here) where finer protection matters. Gauge scale is selectable (MPa, psi or bar; this unit is square, psi), and the check valve (code K) is worth specifying wherever downstream pressure must be held on supply loss. Thread is PT as standard with G and NPT as orderable options - this unit is NPT. Bracket options apply per code.
Because flow is published as curves and not a single rating, ask us to confirm the 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 curves rather than a single rated figure, so we do not quote a number on the page. Send us your line pressure, downstream pressure setting and expected air demand, and we will confirm the flow figures from the datasheet for this exact model before you order.
The W in the code GFR20006F2WTK specifies the optional 5 um filter element instead of the standard 40 um grade, giving finer protection for downstream valves and cylinders. The K specifies a built-in reverse/check valve, which holds downstream pressure if the upstream supply is interrupted. Both are decodable order options on the GFR series, alongside drain type, gauge scale and thread.
