The AirTAC GFR600C20F2WG 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 GFR600C20F2WG is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This 600-size unit is made for 3/4 in lines with G (BSPP) threads, carries the 5 um filtration element (the W grade, against the 40 um standard), and drains by differential pressure, so condensate is expelled automatically as flow passes through. The standard-type regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), an embedded square gauge reading in psi is fitted, and the bowl on this size 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 from the GFR family, which spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, plus choices of drain type, filter grade, gauge and scale, thread (PT standard, with G and NPT as catalogue options) and bracket. Flow is published by AirTAC as curves rather than a single rated figure, so we confirm the datasheet figures for your application on request.

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 3/4 in machine-shop main, the unit strips water and chips-grade particulate down to 5 um and holds a set pressure for tool changers, clamps and spindle-air seals on the machining centre.
Mounted at the drop to a beverage filler, it gives the filler and capper cylinders clean, moisture-controlled air at a steady regulated pressure so fill volumes and capping torque stay repeatable.
Ahead of spray guns and air-assisted atomisers in a paint booth, the 5 um element and stable regulated pressure support an even, uncontaminated finish on vehicle panels.
Step up to the 600 size with the 3/4 in G-thread port when your main runs are larger and your downstream cylinders, valves or tools need volume; smaller branches can drop to the 300 or 400 sizes on 1/4 to 1/2 in ports. This unit is specified with the 5 um element (code W); the 40 um standard element suits general plant air, while 5 um better protects instrumentation, spray equipment and precision valves. Drain is differential-pressure here; automatic (A) and manual (M) drains are available in the same family. The fitted square gauge reads in psi, with MPa or bar scales and an external round gauge as options. A mounting bracket is included.
AirTAC publishes flow for this series as curves, not a single rating, so 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 GFR600 series as performance curves rather than a single rated figure, so there is no one l/min or SCFM number we can quote. Tell us your line pressure, downstream demand and allowable pressure drop, and we will confirm the curve and correct sizing from the datasheet on request.
The W code in GFR600C20F2WG selects the optional 5 um filtration grade; the GFR family default is 40 um. Choose 5 um when feeding spray equipment, instrumentation or precision valves, and stay with 40 um for general plant air. The same family also offers automatic and manual drains if you prefer those over the differential-pressure drain fitted here.
