The AirTAC GFR600C20MLJC1TK 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 AirTAC GFR600C20MLJC1TK is a filter regulator: one body that removes water and particulate from compressed air and regulates the downstream pressure. This size 600 unit carries a 3/4 in NPT port, the standard 40 um filter element, a manual drain on the aluminium alloy bowl, and a low-pressure type regulator, so it is aimed at circuits that run at a reduced set pressure. A round gauge with an MPa scale is fitted, a reverse/check valve is built in, and no mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and the option list includes manual, automatic or differential-pressure drains, a finer 5 um element (code W), embedded square or external round gauges with MPa, psi or bar scales, and G (BSPP) or NPT threads in place of the PT standard. Flow for this series is published as curves rather than a single rating; ask us to confirm sizing and any datasheet figure 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.

Feeding the air supply to a bottling line's valve manifold: water and particulate collect in the manual-drain bowl to be emptied on a routine, while the low-pressure regulator and its MPa gauge let the setter hold a reduced, repeatable set pressure for the valve actuators.
Air preparation for clamping fixtures on a CNC machining cell: the 40 um element screens particulate ahead of the clamping cylinders, and the built-in reverse/check valve helps hold the downstream side of the circuit between cycles.
Supplying diverter and stopper cylinders on a parcel-sortation conveyor: the aluminium alloy bowl with manual drain suits a hub where bowls are checked during scheduled line walks, and the 3/4 in NPT port ties into the main drop leg.
Start with the port step: this unit is the largest GFR size, 600, with a 3/4 in NPT port, while sizes 200/300/400 step down through 1/8 to 1/2 in - match the size to the air demand of the circuit rather than oversizing on guesswork. Drain type is a real operating choice: this configuration uses a manual drain, so the bowl is emptied by hand on a routine; automatic and differential-pressure drain variants exist if manual access is impractical. The 40 um element is the standard grade; specify code W for the 5 um grade where finer particulate protection is wanted. The fitted round gauge reads in MPa, with psi or bar scales available as alternatives. Thread: PT is the AirTAC standard, with G (BSPP) and NPT as orderable options - this code carries NPT. No mounting bracket is fitted on this code.
Because flow for this series is published as curves and not as a single rated figure, we do not quote a number here. Send us your supply pressure, target set pressure and air demand, 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 GFR-series flow as curves rather than as a single rated figure, so we do not quote a number here. Tell us your supply pressure, target set pressure and air demand, and we will confirm the sizing from the datasheet on request.
The M in this code means a manual drain: the aluminium alloy bowl is emptied by hand on a routine. If the unit will be mounted where regular access is difficult, order the automatic or differential-pressure drain variant instead. Note also that this is the low-pressure type of regulator, so confirm the set-pressure range with us before ordering.
