The AirTAC GFR600C20AF2WK AirTAC Filter Regulator PT3/4, 5 um 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 GFR600C20AF2WK 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 3/4 in PT port, a 5 um filter element (the finer of the two published grades), an automatic drain that discharges collected condensate without manual attention, and an aluminium alloy bowl, which is the bowl material used at size 600. The built-in standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), the fitted square gauge reads in psi, and a reverse/check valve is fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. A mounting bracket is included.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with matching port sizes, a choice of 40 um standard or 5 um (W) filtration, differential-pressure, automatic or manual drains, gauge and scale options, and G or NPT thread variants to order. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application before you order.

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.

On a spray-booth air drop, the 5 um element and automatic drain keep water and fine particulate out of the supply while the regulator holds a steady set pressure to the spray guns, with the psi gauge giving operators a local reading.
Feeding the pneumatic cylinders and stopper gates on a bottling conveyor, this unit filters the shop air, regulates it to the pressure the actuator circuit was designed around, and its check valve holds the downstream circuit if supply pressure dips.
Supplying positioner air to diaphragm-actuated control valves in a treatment plant, the GFR600C20AF2WK cleans and regulates the instrument air feed, and the automatic drain copes with condensate in an outdoor or unattended valve manifold.
Size 600 with a 3/4 in PT port is the largest step in the GFR range, so start there when the line demand sits above what a 1/2 in unit can carry, then verify against the flow curve for your actual pressure and required downstream pressure. Drain choice matters: the automatic drain on this model suits unattended or hard-to-reach installations, while manual and differential-pressure drains are the other published options. This unit carries the 5 um element; 40 um is the standard grade if finer filtration is not required. The square gauge here reads in psi; MPa and bar scales and an external round gauge are alternatives. Thread is PT as standard, with G (BSPP) and NPT available as order options, and a bracket is included.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated number, so we do not quote a flow figure here. Send us your line pressure, set pressure and air demand and we will confirm the correct size from the datasheet 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 family as curves rather than a single rated figure, so we do not quote a flow number here. Tell us your inlet pressure, set pressure and air demand, and we will confirm the flow from the datasheet for this exact 3/4 in size 600 unit before you order.
The A in the code sets the automatic drain: collected condensate is discharged without anyone opening the bowl, which suits unattended or hard-to-reach installations. The published alternatives are a manual drain (opened by hand) and the differential-pressure drain, which is the default when no drain letter is specified. Drain choice also affects the published regulation range, so it is worth confirming before ordering.
