The AirTAC AirTAC GFR600C20AC2WK Filter Regulator 3/4 in PT, 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 GFR600C20AC2WK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This size-600 unit is specified with a 3/4 in PT port, the 5 um filter element (the finer of the two catalogue grades), an automatic drain and an aluminium alloy bowl. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi); maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). A round psi gauge and a reverse/check valve are fitted, and the mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and can be ordered with manual or differential-pressure drains, the 40 um standard element, embedded square or external round gauges in MPa, psi or bar scales, G (BSPP) or NPT threads, and with or without a bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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, regulated air for the pallet-clamp and tool-changer circuits of a CNC machining center; the 5 um element and automatic drain help keep condensate and debris out of the clamping valves.
Regulated supply to the cylinders and grippers on a carton-erector and sealing conveyor; the automatic drain handles condensate at the drop without daily manual attention.
Clean, pressure-stabilised air to the spray-gun drops and air-assisted applicators in a paint booth; the 5 um grade and metal bowl suit a line that runs unattended between shifts.
Size steps through 200, 300, 400 and 600 with growing ports (1/8 in to 1 in); pick the size whose flow curve covers your demand at your working pressure - we can check the curve with you. This unit already carries the 5 um element (code W); the standard grade is 40 um if finer filtration is not required. Drain choices are differential-pressure (default), automatic (as fitted here) and manual; note the regulator adjustment range depends on drain type: 0.15-0.9 MPa (20-130 psi) with automatic or differential-pressure drain, 0.05-0.9 MPa (7-130 psi) with manual drain. Gauges are embedded square as standard, with an optional external round gauge in MPa, psi or bar scales; this unit carries the round psi gauge. Thread is PT as standard, with G (BSPP) and NPT as order options, and the bracket is included. Because flow is published as curves rather than a single rating, 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 series as curves, not as a single rated figure, so we do not quote a number here. Tell us your working pressure and air demand and we will confirm the flow from the datasheet for this 3/4 in, size-600 unit before you order.
This unit is fitted with the automatic drain (code A), which discharges collected condensate without manual attention. The catalogue also offers manual and differential-pressure drains; note the regulator adjustment range is 0.15-0.9 MPa (20-130 psi) with the automatic drain, while a manual-drain unit widens the range to 0.05-0.9 MPa (7-130 psi).
