The AirTAC GFR600C20ALC2WGK AirTAC Filter Regulator G3/4, 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 GFR600C20ALC2WGK is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size 600 unit carries a G3/4 (BSPP) port, a 5 um filter element (the W code, against the 40 um standard), and an automatic drain that discharges collected condensate without manual attention. The bowl is aluminium alloy, as is standard at size 600. The regulator is the low-pressure type, and this configuration is fitted with an external round gauge reading in psi, a reverse/check valve, and a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, plus drain, filter-grade, gauge, thread and bracket options to suit the installation. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application.

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.

Prepares the air feeding spray guns and atomising stations on a paint line, removing water and fine particulate and holding a steady, lower regulated pressure so finish quality does not wander between booths.
Conditions and regulates the supply to pneumatic clamps and workholding fixtures on a machining centre, where clean air and a stable setpoint keep parts seated consistently through the cycle.
Sits upstream of the cylinders and air actuators that divert, push and stop cartons on a packaging conveyor, filtering condensate out of the supply and regulating it to the pressure the divert mechanism was set up for.
Size the unit against the air demand of the line: this is size 600 with a G3/4 port, the largest step in the GFR family. Drain type is a real choice - differential-pressure (the default), automatic (fitted here) or manual. Filter grade is 40 um standard or 5 um with the W code (fitted here) where finer particulate removal is needed. On gauges, the embedded square gauge is standard and the external round gauge is optional, with MPa, psi or bar scales; this unit carries a round gauge reading in psi. Thread is PT as the standard, with G (BSPP) and NPT as order options - this unit is G. A mounting bracket is included unless the J code removes it. 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 series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line's air demand and working pressure and we will confirm the correct size from the datasheet on request.
The W code selects the 5 um filter element instead of the 40 um standard, for finer particulate removal upstream of sensitive equipment. The L code makes the regulator a low-pressure type; its exact adjustment range is not published in the catalogue, so we confirm it on request. Everything else on the code is standard decode: automatic drain, round psi gauge, reverse/check valve fitted, bracket included.
