The AirTAC GFR600C20LC2WG 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 GFR600C20LC2WG is an AirTAC GFR-series filter regulator: water and particulate removal plus pressure regulation combined in a single size-600 body with a G3/4 (3/4 in) female thread. This configuration carries the 5 um filter element (code W) for finer air cleaning than the standard 40 um grade, a differential-pressure drain that bleeds accumulated condensate whenever the pressure drop across the element rises, and the low-pressure regulator type for circuits that run below standard line pressures. An external round gauge scaled in psi is fitted so the outlet setting can be read at a glance, and the size-600 bowl is aluminium alloy. 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 options include the 40 um standard element, manual or automatic drains, embedded square or external round gauges scaled in MPa, psi or bar, G or NPT threads in place of the PT standard, and a reverse/check valve. Flow for this series is published as curves rather than a single rating, so ask us to confirm the sizing and 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.

On a weaving shed's ring main, the G3/4 filter regulator conditions the air feeding loom jets and clamp cylinders, with the 5 um element keeping fine lint-laden moisture out of the mechanism at the reduced pressure the looms require.
Mounted at the drop feeding a carton-sealing conveyor, the unit filters the shop air to 5 um and holds the low working pressure that the sealer's flap-fold cylinders need, with the psi gauge letting line staff verify the setting.
On a lab pneumatic test bench supplied from a 3/4 in line, the low-pressure regulator type sets the reduced test pressure while the 5 um element protects sensitive instrumentation from water and particulate carryover.
Start with the port step: size 600 with its G3/4 connection sits at the top of the GFR range, so match it against the pipe bore and the air demand of the circuit - the smaller 200/300/400 bodies cover lighter duty at lower cost. Choose the element grade: 40 um is the standard element, while this unit's 5 um (W) element suits finer protection downstream. Choose the drain: differential-pressure (as fitted here) needs no operator, automatic drains continuously, and manual drain suits infrequently attended points. Pick the gauge and its scale - this unit carries an external round gauge in psi, and square embedded gauges in MPa, psi or bar are available. Thread is G here; PT is the standard and G/NPT are order options. A mounting bracket is included. Because flow is published as curves rather than one rated figure, 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 GFR series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure, working pressure and expected air demand, and we will confirm the sizing against the datasheet on request before you order.
The W code in the model number selects the optional 5 um element, which removes finer particulate and water carryover than the 40 um standard grade. It is the right choice where downstream valves, cylinders or instruments need cleaner air; if your application tolerates coarser filtration, the 40 um version of the same size-600 regulator is available.
