The AirTAC GFR600C20MLNWT AirTAC Filter Regulator 3/4 in NPT 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 GFR600C20MLNWT is a size 600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration carries a 3/4 in NPT port, a 5 um filter element (code W, versus the 40 um standard), a manual drain on the bowl, and the low-pressure regulator type. No gauge is fitted on this variant, and no reverse/check valve is included. At size 600 the bowl is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part from the GFR range, which spans sizes 200 to 600 with port sizes from 1/8 in up to 1 in, in PT (standard), G and NPT threads, with a choice of drain type, filter grade, gauge and scale. Flow figures for this series are published as curves rather than a single rated number, so ask us to confirm sizing and datasheet details 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.

Point-of-use preparation for spray booth and air-knife circuits on a paint line, where the 5 um element helps keep water and particulate out of finish-critical air and the low-pressure regulator type suits circuits run at reduced working pressure.
Supplying regulated, filtered air to the clamp and pusher cylinders on a palletising conveyor, with the 3/4 in NPT port feeding a main drop and the manual drain allowing scheduled bowl draining during shift changeover.
Filtering and regulating the air feeding pneumatic valve actuators on a bottling or filling line, where the low-pressure regulator type matches actuator circuits that operate below standard line pressure and the aluminium bowl suits the size 600 frame.
Choose the size and port step against the air demand of the circuit: this unit is size 600 with a 3/4 in NPT port, the largest step in the GFR range. Drain type is a real choice: manual (as here) means an operator drains the bowl, while automatic and differential-pressure variants handle condensate without intervention. Filter grade is 40 um standard or 5 um (code W) where finer particulate removal is needed - this unit carries the 5 um element. A pressure gauge is optional: embedded square or external round, with MPa, psi or bar scales; this variant is supplied without a gauge. Thread is PT as the catalogue standard with G and NPT as order options; this unit is NPT. A bracket is included.
Because flow for the G-series is published as curves and not as a single rated figure, we cannot quote a rated flow here - send us your application details and we will confirm sizing against the datasheet before you order.
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 G-series as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your application details and we will confirm the flow and datasheet figures for this unit on request before you order.
The M in the code specifies a manual drain: condensate collected in the bowl is released by hand, which suits installations with scheduled maintenance rounds; automatic and differential-pressure drain variants are available in the same series. The W in the code specifies the 5 um filter element instead of the 40 um standard, for finer particulate removal. Note this variant is the low-pressure regulator type and is supplied without a gauge, though gauges are optional in the series.
