The AirTAC GFR600C20MLF2WG AirTAC Filter Regulator G3/4, 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 AirTAC GFR600C20MLF2WG is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is built for a G3/4 (BSPP) port, carries the fine 5 um filter element (code W) instead of the standard 40 um, and uses a manual drain, so an operator opens the drain at the bowl to discharge collected condensate. It is the low-pressure regulator type, comes with the embedded square gauge scaled in psi, has no reverse/check valve fitted, and includes a mounting bracket. At size 600 the bowl is aluminium alloy. Max 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 ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, standard or low-pressure regulation, square or round gauges with MPa, psi or bar scales, PT, G or NPT threads, and bracket options. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

On a textile weaving line, this unit filters the mill air to 5 um and holds a low, stable supply pressure to the jet nozzles, with the psi gauge letting operators check the setting at a glance.
Feeding the seal and clamp cylinders of a case-packing conveyor, it strips water and fine particles before they reach the valves and holds the gentle pressure those low-pressure actuators need.
In a spray-finishing cell, the 5 um element keeps oil-free, dry atomizing air clean while the low-pressure regulator sets the fine supply pressure the spray guns require.
Step up or down through sizes 200, 300, 400 and 600 to match the port and the air demand of the circuit; this unit sits at the top of the range on a 3/4 in G thread. Choose the drain to suit maintenance routines: differential-pressure (default), automatic, or manual as coded here. Pick 40 um for general protection or 5 um (this unit) where downstream equipment needs finer filtration. Gauges are available in square (embedded) or round (external) form with MPa, psi or bar scales; this unit carries the square psi gauge. PT is the standard thread, with G and NPT as order options, and the bracket is included.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated number, so send us your application details and we will confirm the right size from 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 series as performance curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure and air demand and we will confirm the correct size from the datasheet on request.
The M in the code means condensate is released by opening the bowl drain by hand, which suits lines checked on a regular maintenance round. If the unit sits where nobody drains it routinely, choose the automatic-drain version of the same GFR600 configuration instead.
