The AirTAC GFR60020F3WTK AirTAC Filter Regulator 3/4 in NPT 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 PT3/4" 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 GFR60020F3WTK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This 600-size unit is threaded 3/4 in NPT and carries the W filter grade, so it filters to 5 um instead of the standard 40 um - a sensible choice ahead of sensitive valves, cylinders and instruments. The differential-pressure drain bleeds collected condensate automatically whenever the pressure differential across the element is high enough, so no manual draining routine is needed. The bowl on this 600 size is aluminium alloy, the built-in square gauge reads in bar, and the K code means a reverse (check) valve is fitted so downstream pressure is held if the supply drops. A mounting bracket is included.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, square or round gauges with MPa, psi or bar scales, PT, G or NPT threads, and an optional low-pressure regulator type. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi) with this drain type. Flow is published as curves rather than a single rating, so ask us and we will 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.

Filtered and regulated air at each paint-line drop keeps water, particles and pressure swings away from spray guns and air-assisted applicators, protecting finish quality on body and trim panels.
Packaging and case-packing conveyors run on pneumatic diverters, pushers and stopper cylinders; this unit conditions and regulates the supply feeding those valve-and-cylinder groups.
Pneumatic clamps and swing cylinders on machining fixtures need steady, clean air to hold parts consistently through a cutting cycle; a filter regulator at the fixture feed does that job.
Size and port are the first real decision: the GFR family steps through 200, 300, 400 and 600, and the 3/4 in NPT port on this 600 unit should be matched to your line size and the flow your actuators actually need. Because flow is published as curves, not a single rated figure, send us your application and we will confirm sizing against the datasheet before you order. The remaining choices are all decodable from the code: drain type (differential-pressure as here, automatic, or manual - note the manual-drain version has a wider 0.05-0.9 MPa adjustment range), filter grade (40 um standard, 5 um with W as on this unit), gauge style and scale (embedded square is standard, external round is optional, in MPa, psi or bar), thread (PT is the standard; G and NPT are order options), and bracket (included here, or J for none). The K code adds a reverse/check valve, which is worth specifying whenever a load must not creep if supply pressure is lost.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. 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 number, so we do not quote a rated flow, Cv or SCFM figure. Tell us your line pressure and the air your equipment needs, and we will confirm the sizing from the datasheet on request before you order.
The W code selects the 5 um element instead of the 40 um standard grade, which suits downstream valves, cylinders and instruments that need finer filtration. The K code means a reverse (check) valve is fitted, so pressure downstream of the unit is held if the upstream supply is lost. Both are order-time choices - 40 um without W, and no check valve without K.
