The AirTAC GFR20008F1WTK 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 GFR20008F1WTK 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 is fitted with a 5 um filter element (the finer of the two grades), a differential-pressure drain that bleeds collected condensate automatically when the pressure differential across the element rises, an embedded square pressure gauge scaled in MPa, a reverse/check valve that holds downstream pressure when the upstream supply is lost, and a mounting bracket. The port is 1/4 in with NPT thread, and the polycarbonate bowl suits non-freezing installations from -5 to 70 C.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi). Flow is published as curves rather than a single rated figure, so ask us to confirm sizing or any datasheet figure 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 filtered, regulated air to the tool-clamp and tool-change circuits of a CNC machining centre, where the 5 um element protects the clamping valve and the check valve holds clamp pressure during a supply dip.
Supplying the pneumatic diverters, pushers and sealing jaws on a packaging conveyor line, with the square MPa gauge giving operators a clear set-point and the 5 um grade keeping fine air-motor components clean.
Preparing air for the doffing and jet actuator circuits on a textile spinning line, where a compact 1/4 in filter regulator mounted on its bracket sits close to the machine and the differential-pressure drain keeps condensate in check.
Start with the size and port: the 200 series with a 1/4 in NPT port suits compact supply drops, while larger GFR sizes (300/400/600) carry higher flow on bigger ports - match the step to your demand rather than oversizing on guesswork. This unit already carries the finer 5 um element (code W); the standard grade is 40 um, so choose 5 um where downstream valves and cylinders need cleaner air. Drain is differential-pressure as standard; automatic (A) and manual (M) drains are available if your duty or maintenance routine calls for them. The embedded square gauge here reads in MPa; psi and bar scales and an external round gauge are options. Thread is NPT on this code - PT is the AirTAC standard and G (BSPP) is also catalogued, so order the suffix that matches your piping. A bracket is included; J codes omit it. Because flow is published as curves and not a single rating, 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. 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 characteristic curves, not as a single rated number, so we do not quote a figure here. Tell us your line pressure, set pressure and air demand and we will confirm the sizing against the datasheet curves on request before you order.
The W in the code selects the finer 5 um filter grade instead of the standard 40 um element, and the K selects a reverse/check valve that holds downstream pressure if the upstream supply drops. Both are catalogue options on the GFR series; the drain on this code is the standard differential-pressure type, with automatic and manual drains available as alternatives.
