The AirTAC GFR600C20LF1WT AirTAC Filter Regulator 3/4 in NPT 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 GFR600C20LF1WT is a 600-size filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration carries a 3/4 in NPT port, the finer 5 um filter element, a differential-pressure drain on the aluminium alloy bowl, and an embedded square pressure gauge scaled in MPa. It is built as the low-pressure regulator type, so its adjustment range differs from the standard unit - the exact range is not published, and we will confirm it for your line on request.
This is a genuine AirTAC part. The GFR family runs from size 200 to 600 with ports from 1/8 to 1 in, and the catalogue offers manual or automatic drains, a 40 um standard element, psi or bar gauge scales, an external round gauge, a reverse/check valve, and G or NPT threads alongside the PT standard. Rated flow appears only as curves, not a single figure, so share your application and we will confirm sizing and datasheet values 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.

Filtering and regulating the main air drop feeding spray guns on an automotive paint line, keeping water carryover and pressure drift out of the finish.
Conditioning the supply to pneumatic clamps on a machining centre, where a clean, regulated feed supports repeatable workholding at the fixture.
Feeding filtered, regulated air to carton-sealer and case-packing cylinders along a packaging conveyor, with the included bracket easing mounting at the drop.
Size and port are the first choices: this unit steps up to the 600 body with a 3/4 in NPT port, so match it against the air demand of the circuit it feeds. Drain type is a real decision - differential-pressure as fitted here, automatic for unattended condensate removal, or manual where you want controlled discharge. The 5 um element (code W) is the finer alternative to the 40 um standard; the gauge scale can be MPa, psi or bar, and an external round gauge is available. Threads are PT as standard with G and NPT as orderable options, and a mounting bracket is included (code J omits it). Max inlet pressure is 1.0 MPa (145 psi) with a -5 to 70 C non-freezing operating range. AirTAC publishes flow as curves rather than a single rating, so 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 GFR-series flow as curves rather than a single rated figure, so no rated number is quoted here. Send us your line pressure and air demand and we will confirm the flow from the datasheet on request before you order.
Code W fits the finer 5 um element in place of the 40 um standard, which suits downstream valves, cylinders and instruments that need cleaner air. This unit keeps the differential-pressure drain for condensate discharge, and the low-pressure regulator type is unchanged.
