The AirTAC GFR600C20AJF2WTK 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 GFR600C20AJF2WTK is a size-600 filter regulator: water and particulate filtration plus pressure regulation combined in one body, with a 3/4 in NPT port. This configuration is fitted with the 5 um filter element (code W) for finer air cleaning than the standard 40 um grade, an automatic drain that expels collected condensate without manual attention, and an embedded square gauge reading in psi. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), a reverse/check valve is fitted, and no mounting bracket is included. At size 600 the bowl is aluminium alloy, and the maximum working (inlet) pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge and scale options, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application 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.

Feeding a 3/4 in distribution manifold that serves directional control valves on an automated assembly line, keeping filtered air at a set pressure while the automatic drain clears condensate between shifts.
Supplying cleaned, regulated air to the cylinder-driven clamps and pushers on a carton packaging conveyor, where the 5 um element helps protect valve and cylinder seals from fine particulate.
Installed as the point-of-use filter regulator on a production-cell air drop, holding a stable downstream pressure for air tools and fixtures while the check valve holds the setting if supply dips.
The GFR family steps through sizes 200, 300, 400 and 600, each with its own port range, so match the size and port to the air consumption of the line rather than oversizing on guesswork - this unit is the largest step, with a 3/4 in NPT port. Drain choice matters: automatic drain suits unattended or hard-to-reach installations, manual drain suits supervised points, and the differential-pressure default suits standard duty; this unit carries the automatic drain. Filter grade is 40 um standard or 5 um with code W - this unit has the 5 um element, the right choice where finer particulate removal is wanted downstream. Gauge scale can be MPa, psi or bar, and thread can be PT (standard), G or NPT at order time. 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 the GFR family as curves, not as a single rated figure, so we do not quote a rated flow number. Tell us your application and we will confirm the flow and sizing from the datasheet on request.
In the GFR code, A is the automatic drain, which expels collected condensate on its own instead of waiting for a manual or differential-pressure drain, and W selects the 5 um filter element instead of the 40 um standard grade. This unit carries both, plus a square psi gauge, a reverse/check valve, and no mounting bracket.
