The AirTAC GFR20008LC1WTK AirTAC Filter Regulator 1/4 NPT 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 GFR20008LC1WTK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 200-size unit is threaded 1/4 in NPT and carries a 5 um filter element (code W), a differential-pressure drain, and the low-pressure regulator type (code L). It is supplied with a round MPa gauge fitted, a reverse/check valve (code K) and a mounting bracket. The bowl at this size is polycarbonate (PC); only the 600 size uses aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 to 1 in, and the catalogue offers manual or automatic drains, a 40 um standard element, embedded square or external round gauges with MPa, psi or bar scales, and G (BSPP) or NPT threads as orderable alternatives to the PT standard. Flow is 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

On a machining cell where fixtures hold workpieces with air cylinders, this unit filters water and swarf-carrying particulate from the shop air and sets a regulated supply to the clamp circuit. The 5 um element and the check valve help hold the set condition at the fixture between cycles.
Filling, sealing and carton-forming stations on a packaging line run short-stroke air cylinders that are sensitive to moisture and dirt. A filter regulator at each station's drop keeps the air clean and the operating pressure set where the machine builder specified, with the gauge giving a visible reference.
Spray booths and finishing lines need air that is free of water and fine particulate, delivered at a modest regulated pressure to the gun circuit. The low-pressure regulator type on this unit is intended for such circuits, and the differential-pressure drain clears collected condensate from the bowl during operation.
Size and port: this unit is 200 size with a 1/4 in NPT port; the 300, 400 and 600 sizes step up in port and flow capacity, and we can confirm curve data against your demand before you order. Drain: differential-pressure here (the no-code default), with automatic (A) and manual (M) as the alternatives. Filter grade: 5 um on this unit (code W); the standard element is 40 um - choose 5 um where downstream equipment needs finer filtration. Regulator: the L code marks the low-pressure type; its exact adjustment range is not published in the material we hold, so confirm it with us. Gauge: embedded square or external round, with MPa, psi or bar scales - this unit carries a round MPa gauge. Thread: PT is the standard, with G (BSPP) and NPT as catalogue options; this unit is NPT. A mounting bracket is included (code J deletes it).
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 G-series flow as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure and air demand and we will confirm the datasheet curve and check the sizing of this 200-size, 1/4 in NPT unit for your application before you order.
With no drain letter in the code, the bowl uses a differential-pressure drain: condensate collected in the bowl is discharged when the pressure difference across the filter element reaches the operating point. If you would rather drain the bowl by hand on a schedule, the M version gives a manual drain, and the A version gives a fully automatic drain. The drain applies to the filter bowl only - the regulator function has no bowl.
