The AirTAC GFR600C20JF1WTK AirTAC Filter Regulator NPT3/4 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 GFR600C20JF1WTK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and then regulates the downstream pressure. This size 600 unit is built around a 3/4 in NPT port and carries the W-grade 5 um filter element (40 um is the standard grade). The differential-pressure drain uses the pressure differential across the element to eject collected condensate, the embedded square gauge reads outlet pressure in MPa, and the fitted reverse (check) valve holds the downstream setting if inlet pressure dips. Maximum inlet pressure is 1.0 MPa (145 psi), the regulation range is 0.15-0.9 MPa (20-130 psi), the working temperature is -5 to 70 C (non-freezing), and at size 600 the bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um (W) filtration, embedded square gauges or an optional external round gauge with MPa, psi or bar scales, PT, G or NPT threads, and bracket or no-bracket mounting. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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.

Filtered and regulated supply air for a machining center's tool changer, clamps and pilot valves, with the 5 um element protecting fine control components upstream of the machine.
Point-of-use preparation for pneumatic cylinders on a bottling or packaging conveyor, where the regulator holds a fixed downstream setting and the check valve guards it against inlet dips.
A 3/4 in filter regulator feeding a distribution header at an automotive assembly station, conditioning the air before it reaches impact wrenches, air ratchets and clamping fixtures.
Size and port set the capacity: within GFR, the 200/300/400/600 sizes step up in port and flow, and this unit sits at the top of the range with a 3/4 in NPT port. The drain on this code is differential-pressure (automatic and manual are order options); the element is the finer 5 um W grade where 40 um is standard; the gauge is the embedded square type on an MPa scale, with psi and bar scales and an external round gauge available. The thread here is NPT, with PT as the standard and G (BSPP) also orderable, and the J code means no mounting bracket is fitted. Flow is published as curves, not 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 flow for this family as curves, not as a single rated figure, so there is no one l/min or SCFM number we can quote. Tell us your working pressure and demand and we will confirm the flow from the datasheet for your application on request.
The differential-pressure drain on this unit ejects collected condensate using the pressure differential across the filter element, with no extra operator attention. If your duty cycle suits it, automatic (A) or manual (M) drain versions of the same GFR600 unit can be ordered instead.
