The AirTAC GFR600C20MLC2TK AirTAC Filter Regulator NPT3/4 Low-Pressure 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 GFR600C20MLC2TK is an AirTAC GFR600 filter regulator: a single body that removes water and particulate from compressed air and regulates downstream pressure. This size 600 configuration carries a 3/4 in NPT port, the low-pressure regulator type, a manual drain on the bowl, the standard 40 um filter element, and a metal bowl (size 600 is aluminium alloy). It is supplied with a round external gauge scaled in psi, a reverse/check valve fitted, and a mounting bracket.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with a choice of port, thread (PT standard; G and NPT as order options), drain type, filter grade, gauge style and scale, and low-pressure or standard regulator type. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application on request.

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.

Feeds filtered, regulated air to the low-pressure actuation circuit of a carton-sealing or wrapping machine, where the line runs below standard shop-air pressure and a manual-drain bowl suits a supervised daily check.
Conditions the air feeding rollers, cylinders and low-pressure controls on printing or textile machinery, with the 40 um element catching water and particulate before it reaches sensitive components.
Supplies regulated low-pressure air to nozzles or air knives that clear dust and debris from products moving along a conveyor, with the reverse/check valve holding the downstream setting.
Size 600 with a 3/4 in port is the largest step in the GFR range, so start by matching the port and size step to the pipe and the air demand of the circuit. This unit is the low-pressure regulator type, intended for circuits that run below standard line pressure; ask us to confirm the exact adjustment range from the datasheet. The manual drain means someone bleeds the bowl by hand on a routine, so choose it where a drain point is easily reached; automatic or differential-pressure drains suit less accessible installs. The 40 um element is the standard grade; specify 5 um (code W) only where finer filtration is required. The round gauge fitted here reads in psi; square embedded gauges and MPa or bar scales are the alternatives. Thread is NPT on this code; PT is the catalogue standard and G is also orderable. A bracket is included. Because flow is published as curves rather than a single rating, 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 G-series flow as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure, downstream setting and air demand, and we will confirm the flow from the datasheet curves for this exact configuration on request.
The M in the code selects a manual drain: accumulated water is bled from the bowl by hand, which suits installations that are checked regularly. The L selects the low-pressure regulator type, for circuits that run below standard line pressure; the exact adjustment range for this type is not published in the summary data, so we confirm it from the datasheet on request.
