The AirTAC GFR600C20MLC1TK 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 GFR series combines water and particulate filtration with pressure regulation in a single body, so one unit cleans the air and holds a steady downstream pressure. This GFR600C20MLC1TK is the size 600 configuration with NPT3/4 ports, a 40 um standard filter element, a manual drain on the bowl, and a low-pressure type regulator. The metal bowl on this size 600 unit is aluminium alloy, drained by hand via the manual drain. A round pressure gauge scaled in MPa is fitted, a reverse (check) valve is built in to hold downstream pressure if the supply drops, and a mounting bracket is included.
This 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 that include automatic or differential-pressure drains, a 5 um element (code W), square or round gauges with MPa, psi or bar scales, and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, so ask us and we will 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.

At a 3/4 inch take-off from a factory air ring main, this filter regulator cleans the supply of water and pipe scale and holds a steady, reduced pressure to the downstream drop, with the check valve helping to hold that setting if the main fluctuates.
Packaging and conveyor lines run many cylinders and actuators off one branch. Feeding that branch through this unit removes condensate and particles and gives the line a single, stable regulated pressure set on the fitted MPa gauge.
Process skids and test benches that need air regulated to a low setpoint suit the low-pressure type regulator here, with the 40 um element protecting downstream instruments and the manual drain suiting a supervised bench environment.
Start with the port step: size 600 with 3/4 inch NPT ports is the largest GFR frame, so match it to the line size and the flow your circuit needs - and because flow is published as curves rather than one rated number, send us your application and we will confirm sizing from the datasheet before you order. This unit carries the 40 um standard element; if the application needs finer filtration, the 5 um W-grade element is the alternative to discuss. The manual drain on this configuration means someone drains the bowl by hand on a schedule - if that does not suit the installation, the automatic or differential-pressure drain options are worth considering. The fitted round gauge reads in MPa; psi and bar scales are available, and an embedded square gauge is the standard alternative. NPT is the thread on this unit; PT is the catalogue standard and G (BSPP) is also an order option. A mounting bracket is included.
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, not as a single rated number, so we do not quote a figure that could mislead your sizing. Tell us your operating pressure and the flow your circuit needs, and we will confirm the datasheet curve figures for this size 600 unit on request before you order.
The M in the code selects a manual drain: the aluminium alloy bowl is emptied by hand, which suits installations that are checked regularly. AirTAC also offers an automatic drain (code A) and a differential-pressure drain (the default, no code letter) on GFR units, so if unattended drainage matters at this 3/4 inch size, ask us about those variants.
