The AirTAC GFR600C20NWT AirTAC Filter Regulator NPT3/4 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 GFR600C20NWT is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This size-600 unit is fitted with NPT3/4 ports, 5 um filtration (the finer W-grade element, versus the 40 um standard), a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and an aluminium alloy bowl suited to the larger frame. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi), and operating temperature is -5 to 70 C (non-freezing). No gauge is fitted on this variant; a gauge can be specified on other codes in the series.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600, with port options from 1/8" to 1", a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, gauge and thread options, and PC or aluminium alloy bowls depending on size. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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-inch drop from a factory compressed-air ring main, the unit cleans water and scale out of the supply and holds a steady regulated pressure to the machines fed from that drop, with the differential-pressure drain shedding collected condensate as air passes through.
A CNC machining centre's pneumatic valves and tool-change cylinders behave best on clean, stable air; the 5 um element strips fine particulate ahead of the machine while the regulator holds the supply pressure the machine builder specifies.
On a packaging line branch serving carton sealers, case erectors and actuator manifolds, the filter regulator protects downstream components from moisture and dirt and keeps branch pressure constant as other machines on the header cycle on and off.
Size 600 with NPT3/4 ports sits at the top of the GFR range - step up or down through 200/300/400/600 to match the pipe size and flow demand of your line, since larger sizes carry larger ports and more flow. This unit pairs the finer 5 um element (code W) with a differential-pressure drain; choose automatic drain if you want timed condensate removal, or manual drain for infrequently attended points. Regulation adjustment is 0.15-0.9 MPa (20-130 psi) with the differential-pressure drain, and no gauge is fitted on this code - other GFR codes add an embedded square gauge or an external round gauge with MPa, psi or bar scale. Thread is NPT here; PT is the standard thread and G (BSPP) is also a catalogue option. A mounting bracket is included. Flow is published as curves, not a single rating, so have us 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 there is no one flow number we can quote for this unit. Tell us your line pressure, set pressure and expected air demand, and we will confirm the flow from the datasheet curves on request before you order.
The W in the code GFR600C20NWT selects the finer 5 um filtration element instead of the 40 um standard, which suits applications feeding sensitive pneumatic components. The N selects no gauge, so the regulator is set against your own downstream gauge; other GFR codes add an embedded square gauge or an external round gauge in MPa, psi or bar scale if you prefer a fitted indication.
