The AirTAC GFR600C20MLJC2WK 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 GFR600C20MLJC2WK is a filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This size 600 unit is built around a 3/4 in PT port and carries a 5 um filter element (the finer of the two published grades), a manual drain on its aluminium alloy bowl, and a low-pressure regulator fitted with an external round gauge reading in psi. A reverse/check valve is fitted and the unit is supplied without a mounting bracket.
This is a genuine AirTAC part from the GFR series, which spans sizes 200 to 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, standard or low-pressure regulation, and G or NPT thread options to order. 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 rating, so ask us to confirm 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.

Feeding atomizing air to spray guns in a paint or powder-coating booth: the 5 um element strips water and grit that would fish-eye a finish, while the low-pressure regulator holds a gentle, repeatable gun pressure.
Supplying the 3/4 in air drop that runs cylinders and vacuum generators on a packaging conveyor; filtered, regulated air keeps stroke timing consistent through a full shift.
Conditioning the pilot supply to quarter-turn actuators and solenoid valves in a water-treatment or process plant, where the fitted check valve holds the circuit and the 5 um element protects sensitive pilots.
Choose GFR when one body must both filter and regulate. Step up through sizes 200, 300, 400 and 600 as your flow demand and port size grow - this unit is the 600 size with a 3/4 in PT thread (G or NPT threads are order options). Pick the drain to match your maintenance habits: manual (as here) needs someone to open the bowl drain, automatic empties itself, and the default differential-pressure drain dumps when the pressure drop rises. Choose the 5 um element (code W) when downstream equipment needs finer air than the 40 um standard. Gauge style and scale (MPa, psi or bar) are selectable, and a bracket can be added if you would rather not order the J (no-bracket) build. Because flow is published as curves rather than a single rating, send us your application details and we will confirm sizing against 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 series as curves rather than a single rated figure, so we do not quote a number here. Tell us your inlet pressure and the flow your application needs and we will confirm the sizing from the datasheet on request.
This unit is ordered with a manual drain: someone opens the bowl drain to discharge collected water. If the unit is mounted where regular draining is awkward, the same GFR600 filter regulator can be ordered with an automatic drain or the default differential-pressure drain - just ask and we will quote the variant.
