The AirTAC GFR600C20MLF2G AirTAC Filter Regulator G3/4 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 GFR600C20MLF2G is a size 600 filter regulator: water and particulate removal plus pressure regulation combined in one body. This configuration carries a G3/4 thread, a 40 um standard filter element, a manual drain on the bowl, and a low-pressure regulator type. The bowl on size 600 units is aluminium alloy, a mounting bracket is included, and the fitted embedded square gauge reads in psi. 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. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and is ordered with choices of drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um with code W), gauge scale (MPa, psi or bar) and thread (PT standard, with G and NPT as catalogue options). Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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.

Mounted at the drop of a packaging line's air header, this unit filters condensed water and swarf from the shop supply and holds a reduced, low-pressure setting for wrapper cylinders and sealing jaws that cannot see full line pressure.
On a bottling or carton conveyor, the G3/4 connection feeds a bank of stopper and pusher cylinders, with the 40 um element protecting valve seals and the low-pressure regulator keeping gentle, repeatable actuation at the guide rails.
On a water-treatment or chemical dosing skid, this unit conditions the instrument-air feed to pneumatically actuated diaphragm valves, filtering particulate and regulating the actuator pressure to the low setting the valve maker specifies.
Start with the size and port step: 600 is the largest G-series size, and the G3/4 thread here suits lines with higher air demand - match the port against the flow your circuit needs. Because this is the low-pressure regulator type, confirm its regulation range against your set pressure before ordering; the exact range for the low-pressure type is not published in the sheet we carry, and we will confirm it on request. Drain type is a real choice: manual (as here) means someone opens the drain, while automatic and differential-pressure drains discharge condensate without attention. Filter grade is 40 um standard or 5 um with code W if downstream equipment needs finer filtration. Gauge scale is selectable (MPa, psi or bar) and this unit ships with the square gauge reading psi. Thread is PT as standard with G and NPT as order options; a mounting bracket is included.
One honest note on sizing: flow for this family is published as curves, not a single rated figure, so send us your application details and we will confirm the 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 GFR family as curves, not as a single rated number, so we do not quote a l/min, m3/h or SCFM figure. Send us your line pressure, set pressure and expected air demand, and we will confirm the sizing from the datasheet on request.
The M in the code specifies a manual drain: condensate collects in the aluminium alloy bowl and is released by opening the drain fitting. If you cannot rely on routine drain checks, the same size 600 GFR unit can be ordered with an automatic drain (code A) or a differential-pressure drain (blank), which discharge condensate without operator attention.
