The AirTAC GFR600C20MLF3WTK AirTAC Filter Regulator NPT 3/4 in 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 GFR600C20MLF3WTK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is built for a 3/4 in NPT port, carries the fine 5 um filter element (code W), drains by hand through its manual drain, and is the low-pressure regulator type. It ships as specified with an embedded square gauge reading in bar, a reverse/check valve fitted, an included mounting bracket, and - being a 600-size unit - an aluminium alloy bowl. 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 from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, standard or low-pressure regulation, gauge and thread options, and optional check valves. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing or 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.

Mounted ahead of a directional-valve manifold on a packaging machine, it filters water and chips from the plant air, holds a reduced low-pressure setting for the valve pilots, and its check valve stops downstream air pushing back through the unit.
On a beverage line's conveyor and gating cylinders, the 3/4 in NPT port feeds high-draw sections, the 5 um element protects cylinder seals from particulate, and the manual drain suits a line that is blown down at every shift change.
At a weld cell where fixtures and clamps run at reduced pressure, the low-pressure regulator type sets the circuit below full line pressure, the bar-scale square gauge gives operators a local reading, and the aluminium bowl and bracket suit a fixed panel build.
Step up through sizes 200, 300, 400 and 600 as your port and flow demand grows; this unit is the 600 size with a 3/4 in NPT port, the largest in the family. Choose the 5 um element (as here) when downstream valves or instruments need finer filtration than the 40 um standard. Pick manual drain (as here) when an operator is on site to drain the bowl, or specify automatic or differential-pressure drain where the unit runs unattended. Gauge scale is selectable between MPa, psi and bar - this unit reads bar on the embedded square gauge, with an external round gauge available. Thread is PT as standard with G (BSPP) and NPT as order options; this unit is NPT. A bracket is included, and the fitted reverse/check valve blocks backflow through the unit.
Two honest routings: flow is published only as curves, not a single rated number, so send us your flow requirement and we will confirm this size against the datasheet before you order. This is also the low-pressure regulator type, and its exact regulating range is not published in the catalogue - we will confirm it on request.
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 figure, so we do not quote a l/min or SCFM number. Tell us your operating pressure and required flow and we will confirm from the datasheet curves whether this 600-size, 3/4 in unit is correctly sized before you order.
The 5 um element (code W) is the finer of the two published grades - the standard is 40 um - so it suits circuits with valves, cylinders or instruments that need cleaner air. The manual drain (code M) means an operator drains the aluminium alloy bowl by hand, which fits attended cells; for unattended duty, ask us about the automatic or differential-pressure drain versions of the same unit.
