The AirTAC GFR600C20AF2WTK 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 AirTAC GFR600C20AF2WTK is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This size 600 unit is fitted with a 3/4 in NPT port, a 5 um filter element, an automatic drain that ejects collected condensate without manual attention, and an embedded square pressure gauge reading in psi. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and a reverse/check valve is fitted. At size 600 the bowl is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR filter-regulator family 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 standard or 5 um (W) elements, gauge 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 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.

Installed at the drop to a CNC machining centre, it removes water and fine particulate from the shop air and holds a steady regulated pressure to the machine's pneumatic valves and clamps. The automatic drain keeps condensate off the machine without daily attention.
Mounted on the air drop feeding cylinder-driven fill, capping and eject stations on a bottling line, it conditions the supply and keeps actuator pressure constant through shift-long cycling. The 5 um element helps protect sensitive pilot valves.
Fitted upstream of a manifold serving pick-and-place and press-fit stations on an automated assembly cell, it filters the incoming air and regulates it to the pressure the circuit was designed around. The psi gauge and check valve support stable, monitored supply.
Choose the size and port step against the air demand of the circuit: this unit is size 600 with a 3/4 in NPT port, the largest step in the GFR range, suited to lines with higher air consumption. Drain type is a real choice: differential-pressure (default), automatic (this unit) or manual; automatic drain suits points that are hard to reach or run unattended. Filter grade is 40 um standard or 5 um with the W code (this unit) for finer protection of downstream tools and instruments. Gauge scale is selectable (MPa, psi or bar) and the square gauge is embedded as standard with an external round gauge optional. Thread is PT as standard with G and NPT as order options; a bracket is included unless the J code is specified.
Flow for this family is published as curves, not a single rated number, so we cannot quote a rated flow here. Send us your application details and we will confirm the sizing against the datasheet curves before you order.
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 figure, so we do not quote a rated flow, Cv or SCFM number here. Tell us your application and air demand and we will confirm the sizing against the datasheet curves on request before you order.
The A code in this model specifies an automatic drain, which ejects collected condensate on its own so the bowl does not need regular manual draining. The GFR family also offers the differential-pressure drain (the default) and a manual drain (M), so you can match the drain to how accessible the installation point is.
