The AirTAC GFR600C20MLC2W AirTAC Filter Regulator 3/4 in PT, 5 um 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 GFR600C20MLC2W is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This size-600 unit carries a 3/4 in PT port, a 5 um filter element (the finer of the two published grades), a manual drain for the bowl, and a low-pressure regulator type. It is fitted with an external round pressure gauge scaled in psi, and no reverse/check valve is fitted. The metal bowl on this 600 size is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of drain type, 40 um or 5 um filtration, gauge style and scale, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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 air preparation on a packaging or assembly line: this unit filters water and particulate from the 3/4 in supply and lets a technician set and read the working pressure in psi at the machine.
Supplying pneumatic actuators and cylinders on conveyor and material-handling systems, where the 5 um element helps protect valves and cylinders from finer contamination and the regulator holds a stable set pressure.
A maintenance or plant-air drop feeding air tools and clamping fixtures, with the manual drain serviced during routine checks and the mounting bracket used to secure the unit at the drop point.
Size and port set the capacity envelope: this is the largest GFR size (600) with a 3/4 in PT port, suited to lines where higher flow demand is expected - match the size step to your required flow. The 5 um element (code W) suits downstream equipment that needs finer particulate removal than the 40 um standard. The manual drain means an operator opens the drain periodically; choose automatic or differential-pressure drain codes if unattended water removal is needed. Note this is the low-pressure regulator type, so confirm the working band suits your circuit. The round gauge is scaled in psi; square embedded gauges and MPa or bar scales are available. PT is the standard thread with G (BSPP) and NPT as orderable options, and a mounting bracket is included. 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 curves, not as a single rated figure, so we do not quote a flow number. Tell us your line pressure and required flow and we will confirm the sizing from the datasheet curves on request before you order.
The M in the code sets a manual drain: collected condensate is emptied by opening the drain by hand on a scheduled basis, rather than automatically. The W sets the 5 um filter element, one grade finer than the 40 um standard, for applications that need cleaner air downstream. If unattended drainage is preferred, other GFR codes offer automatic or differential-pressure drains.
