The AirTAC GFR600C20LF1WTK AirTAC Filter Regulator NPT3/4 5um is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet 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 GFR600C20LF1WTK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 5 um filter element (code W), a differential-pressure drain, a low-pressure regulator type, an embedded square gauge with MPa scale, and a reverse/check valve, all on a 3/4 in NPT port. The metal bowl on this 600 size is aluminium alloy, and the unit is supplied with a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of 40 um standard or 5 um fine filtration, differential-pressure, automatic or manual drains, PT, G or NPT threads, and gauge or no-gauge builds. Flow figures are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details 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 clamp cylinders on a milling or drilling fixture, this unit filters the shop air to 5 um and holds the circuit at a reduced, repeatable pressure so delicate workpieces are held without over-clamping.
Mounted ahead of the air line to spray guns in a paint booth, the 5 um element strips water and particulate that would otherwise cause fisheyes and defects, while the regulator steadies gun supply pressure.
On a packaging line with low-pressure air actuators for flaps, pushers and bag clamps, this filter regulator cleans the supply and keeps actuator pressure stable across the shift, with the check valve holding the setting if upstream air dips.
Size 600 with a 3/4 in port sits at the top of the GFR range, so step up or down (200/300/400/600) according to the air demand of the circuit rather than the pipe alone. This unit is already specified with the 5 um element (W); the standard grade is 40 um if finer filtration is not required. The differential-pressure drain bleeds the bowl automatically as pressure drops, with no operator action, while automatic (A) and manual (M) drains are alternative builds. The low-pressure regulator type suits circuits held well below full line pressure; its exact adjustment range is not published, so confirm it with us. Thread is NPT here; PT is the standard and G is also a catalogue option. A bracket is included, and the embedded square gauge reads MPa (psi and bar scales and an external round gauge are alternatives).
Because flow is published as curves rather than a single rated figure, ask us to confirm sizing against your application before ordering.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back 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 l/min or SCFM figure. Send us your application details and we will confirm the flow curve and sizing from the datasheet on request.
The W in the code GFR600C20LF1WTK specifies the optional 5 um filter grade, which removes finer water and particulate than the 40 um standard element. It suits applications such as spraying or instrumentation; if your circuit does not need fine filtration, the 40 um standard grade is the usual choice.
