The AirTAC AirTAC GFR600-20MLC2WK Filter Regulator 3/4in PT 5um 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 GFR600-20MLC2WK is a filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This size-600 unit is fitted with a 3/4in PT port, a 5 um filter element (the finer of the two published grades), a manual drain for controlled bowl evacuation, and a low-pressure regulator type. An external round gauge with a psi scale is included, a reverse/check valve is fitted, and the mounting bracket is supplied. At size 600 the bowl is aluminium alloy, and the maximum working pressure is 1.0 MPa (145 psi) with an operating temperature of -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600, with port sizes from 1/8in to 1in, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filtration, standard or low-pressure regulation, gauge and scale options, PT, G or NPT threads, and optional reverse/check valves. Flow figures for this family are published as curves rather than a single rating, so we confirm the exact 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.

On a production press line, this unit cleans the shop air to 5 um and holds a low, stable working pressure to the clamping cylinders, with the psi gauge giving operators a direct reading at the station.
Packaging machines with sensitive valves benefit from the 5 um element and regulated low-pressure supply, while the manual drain lets maintenance staff evacuate the aluminium bowl during scheduled washdown and changeover.
Wide machines with many air-driven actuators use a single 3/4in feed; this filter regulator conditions and sets the pressure for the whole control circuit, and the fitted check valve holds the setting if the main supply dips.
Start with the port step: GFR comes in sizes 200, 300, 400 and 600, stepping up from 1/8in to 1in ports, so match the size to the air demand of the circuit. This unit is already the 3/4in PT-threaded size-600 version. Then pick the drain: manual (as here) gives you deliberate, controlled draining, while automatic and differential-pressure drains handle condensate without operator action. Choose the element grade: 40 um is standard for general protection, 5 um (code W, fitted here) for finer downstream cleanliness. Gauge scale (MPa, psi or bar), the low-pressure regulator type, the reverse/check valve and the bracket are the remaining decodable options. Because flow is published as curves rather than a single rated figure, 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 flow for the GFR series as performance curves, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the relevant flow and datasheet figures for this exact model on request before you order.
Manual drain means condensate is emptied from the aluminium bowl by operating the drain by hand, which suits duties with regular maintenance rounds. The L in the code marks the low-pressure regulator type, intended for lower working pressures than the standard version; its exact adjustment range is not published in the catalogue, so we confirm it on request. The C2 also gives you an external round gauge with a psi scale.
