The AirTAC GFR600C20ALC2WK AirTAC Filter Regulator 3/4 in PT 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 GFR600C20ALC2WK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built around a 3/4 in PT port and a 5 um filter element (code W), so it captures finer contamination than the standard 40 um grade. The automatic drain (code A) ejects collected condensate without anyone having to open the bowl, which suits duty where the unit is mounted in a less accessible position. The regulator is the low-pressure type (code L), and the code also specifies a round external pressure gauge reading in psi (C2), a reverse/check valve (K), and the included mounting bracket. At size 600 the bowl is aluminium alloy, and the maximum working (inlet) pressure is 1.0 MPa (145 psi) with an operating temperature range of -5 to 70 C, non-freezing.
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, and is ordered with your choice of drain type, filter grade, gauge style and scale, thread (PT standard, with G and NPT as order options), bracket and check valve. Rated flow for this series is published as curves rather than a single figure, so ask us and we will confirm the flow and datasheet figures for this exact model against 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.

Feeding spray guns and air-assisted applicators on a paint line, where the 5 um element helps keep water and fine contamination out of the finish and the low-pressure regulator holds a gentle, stable supply to the guns.
Conditioning air for carton sealers, case erectors and conveyor diverters on a packaging line, with the automatic drain clearing condensate through long shifts and the check valve holding the circuit if upstream supply dips.
Supplying filtered, regulated air to clamps and fixtures on a CNC or machining cell, where the 3/4 in port serves a larger header and the psi gauge lets setters verify the clamp circuit at a glance.
Size 600 with a 3/4 in PT port sits at the top of the GFR range, so step up or down through the 200/300/400/600 sizes against the flow your line needs - and because flow is published as curves rather than one rated number, ask us to confirm the sizing before ordering. Drain choice matters: this unit has the automatic drain (A), which suits unattended or hard-to-reach installations; manual and differential-pressure drains are available on other codes in the family. The 5 um element (W) is the finer option against the 40 um standard - choose it where downstream valves and instruments are sensitive. The round external gauge here reads in psi; embedded square gauges and MPa or bar scales are the other gauge choices. Thread is PT as standard, with G (BSPP) and NPT available as order options, and the bracket is included with this code. Note that this is the low-pressure regulator type (L); its exact adjustment range is not published in the catalogue, so confirm it with us for your set pressure.
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 number, so we do not quote a figure here. Tell us your line pressure and the flow your application needs and we will confirm the flow from the datasheet for this exact 3/4 in, size 600 model before you order.
Code A in GFR600C20ALC2WK specifies the automatic drain, which expels collected condensate on its own - useful where the unit is mounted high, inside a cabinet or anywhere nobody walks past to bleed it. The GFR family is also available with manual or differential-pressure drains on other codes, and the filter grade can be the 40 um standard instead of the 5 um element fitted here.
