The AirTAC GFR600C20MLJC3WTK AirTAC Filter Regulator NPT3/4 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 GFR600C20MLJC3WTK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and regulates the downstream pressure. This 600-size unit is threaded NPT3/4 (3/4 in), carries a 5 um filter element (code W), a manual drain on the aluminium alloy bowl, and the low-pressure regulator type. A round pressure gauge with a bar scale is fitted, a reverse/check valve is included, and the unit is supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
It is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and options for drain type (differential-pressure, automatic or manual), 40 um or 5 um filtration, gauge style and scale, PT, G or NPT thread, bracket, and reverse/check valve. 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.

Conditions the air feeding cylinder and valve manifolds at a filling or capping station where the circuit is set to a reduced pressure and the low-pressure regulator type is the right match.
The 5 um element with water removal helps protect spray-gun atomising air and solenoid valves from particulate and moisture carryover in a finishing booth.
Installed at the machine drop to filter and regulate the supply to a case packer, with the fitted reverse/check valve and round bar gauge giving local setting and indication.
Choose the size by port and air demand: this is the 600 size with a 3/4 in NPT thread, the largest step in the GFR range, so match it against your consumption before ordering. This code fixes several real choices: 5 um filtration instead of the standard 40 um, a manual drain (the bowl is drained by hand at intervals; automatic and differential-pressure drains are alternative codes), the low-pressure regulator type, a round gauge reading in bar, a reverse/check valve, and no mounting bracket. Thread is NPT here; PT is the standard and G (BSPP) is also an order option. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing against the datasheet.
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 operating pressure and air consumption and we will confirm the flow from the datasheet for this exact 3/4 in configuration before you order.
This model has a manual drain: condensate collected in the aluminium alloy bowl is released by operating the drain by hand as part of routine checks. If you prefer unsupervised condensate removal, the GFR600 is also available with an automatic or a differential-pressure drain under a different code - ask us for the alternative model.
