The AirTAC GFR600C20MLF2WK 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 GFR600C20MLF2WK is an AirTAC GFR-series filter regulator: water and particulate separation and pressure regulation combined in one body. This size 600 unit is built around a 3/4 in PT port and carries the W 5 um filter element in place of the standard 40 um, a manual drain on the aluminium alloy bowl, the L low-pressure regulator type, an embedded square gauge scaled in psi, a reverse/check valve, and a mounting bracket.
It is a genuine AirTAC part for compressed air, rated at up to 1.0 MPa (145 psi) inlet and -5 to 70 C (non-freezing). The GFR family spans sizes 200 to 600 with ports from 1/8 to 1 in, and choices of drain type, filter grade, gauge scale and G or NPT thread. AirTAC publishes flow as curves rather than a single rating; ask us and we will 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.

Point-of-use conditioning for a 3/4 in drop feeding carton-sealing and case-erector cylinders: water and 5 um particulate removed, with pressure set at the low level the machine was commissioned for and read directly off the psi gauge.
Clean, low-pressure regulated air for a leak-test or calibration bench, with the check valve holding the circuit steady if shop supply dips and the manual drain emptied as part of the bench start-up routine.
Conditioned supply to air-cylinder operated diverters, gates and stops on a conveyor line, with the 5 um element protecting the valve stack and the manual drain clearing collected water at shift start.
The real choices in this family are all decodable from the code. Step through sizes 200/300/400/600 to match the port your line needs - here 3/4 in PT, with G and NPT threads available as order options. Pick the drain: differential-pressure (default), automatic (A), or manual (M, as fitted here) where draining the bowl is part of a routine. Pick the element: 40 um standard or 5 um (W) for finer protection of downstream equipment. Choose the gauge scale - MPa, psi or bar - and keep or omit the bracket. This unit is the L low-pressure regulator type; its exact adjustment range is not published in the material we hold, so confirm it with us. Flow is published as curves, not a single rating, so ask us to check 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 this family as curves, not as a single rated figure, so we do not quote a number. Send us your application details and we will confirm the datasheet flow figures so you can size the unit against your demand before ordering.
The M in the code means the aluminium alloy bowl is drained by hand rather than automatically. It suits lines where someone is already on site each shift; if the unit sits unattended, the automatic (A) or differential-pressure (default) drain variants empty the bowl without operator action.
