The AirTAC GFR600C20MLC3WT 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 AirTAC GFR600C20MLC3WT is a filter regulator: one body that removes water and particulate from compressed air and then regulates the downstream pressure. This size 600 unit has a 3/4 in NPT port, a manual-drain bowl in aluminium alloy, and the 5 um filter element (code W), the finer of the two published grades. The regulator is the low-pressure type (code L); its exact adjustment range is not published, so confirm it against your set pressure with us before ordering. It is fitted with an external round gauge scaled in bar and includes a mounting bracket.
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of manual, automatic or differential-pressure drain, 40 um or 5 um filtration, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rated figure, so ask us to confirm the sizing numbers from the datasheet for your application.

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 spray guns in a paint booth: the 5 um element strips water and pipe scale that would fisheye a finish, and the regulator holds the atomizing pressure the gun setup calls for, with a direct bar readout on the round gauge.
Supplying clamp and hold-down cylinders on a carton-sealing line, where filtered air protects valve seats and cylinders, and the low-pressure regulator type is chosen for circuits whose set point sits at the low end - we confirm the exact range before you order.
Providing clean, regulated air to pneumatic test rigs and instrument panels in a workshop lab, where the 5 um grade protects sensitive gauges and instrumentation and the round bar gauge gives the operator a direct pressure readout.
Size and port step up together across 200, 300, 400 and 600; this unit is size 600 on a 3/4 in NPT port. Pick the size whose flow curve covers your demand with margin, and ask us to check it against the datasheet. Drain type is a real choice: manual (this unit) means periodic bowl draining by hand, automatic drains continuously, and the differential-pressure default drains on a pressure drop. Filter grade is 5 um here against the 40 um standard - choose 5 um where finer downstream cleanliness matters. Gauge options are the embedded square gauge or an external round gauge, scaled in MPa, psi or bar; this unit carries a round gauge in bar. Thread is NPT here; PT is the standard and G is also an order option. Because this is the low-pressure regulator type, confirm its adjustment range against your set point 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 curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure, set pressure and air demand, and we will confirm the flow figures from the datasheet for this exact model before you order.
The code M means a manual drain: someone opens the bowl drain periodically to remove collected water, which suits installations that are easy to reach and checked regularly. If the bowl sits where draining by hand is impractical, the same size 600 filter regulator can be ordered with an automatic drain (code A) or the differential-pressure default - ask us for the alternative model code.
