The AirTAC GFR600C20F2WT AirTAC Filter Regulator, NPT3/4, 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 GFR600C20F2WT is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 3/4 in NPT port, a 5 um filter element (the finer of the two published grades), a differential-pressure drain that bleeds collected condensate as pressure differential builds, and a square pressure gauge reading in psi. 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). At size 600 the drain bowl is aluminium alloy, and the unit operates in -5 to 70 C (non-freezing) conditions.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, with a choice of drain type, 40 um or 5 um filtration, gauge scale, PT/G/NPT thread and bracket options. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the 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.

Point-of-use conditioning ahead of a machining centre's pneumatic valve stack: the 5 um element protects directional valves and cylinders from particulate and condensed water while the regulator holds a steady supply pressure to the tool changer and clamps.
Conditioning and regulation on the 3/4 in main feeding a packaging line's carton-forming and sealing cylinders, where the differential-pressure drain keeps condensate off the actuators and the psi gauge lets operators verify set pressure at a glance.
A filtered, regulated drop at the head of an assembly cell's air ring main: the size-600 frame with 3/4 in NPT port sits on the cell's supply drop, delivering clean air at the pressure the cell's fixtures and air tools were set up for.
Size and port set the capacity envelope: the 600 frame with its 3/4 in port is the largest step in the GFR range, so step up or down through 200/300/400/600 against the flow your line needs. Choose the drain to match maintenance practice: differential-pressure (as fitted here) drains automatically in service, automatic (A) drains on a cycle, and manual (M) drains only when opened. Filtration is 40 um standard or 5 um with the W code - this unit carries the 5 um element. Gauge scale is selectable (MPa, psi or bar) and the square gauge is embedded as standard with an external round gauge optional. Thread is PT as the catalogue standard, with G and NPT as order options; a mounting bracket is included with this unit. Because flow is published as curves rather than a single rating, 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 number, so we do not quote a rated flow, Cv or SCFM figure. Send us your application details and we will confirm the datasheet flow curve and help you check the sizing before you order.
The W code in the model number selects the finer 5 um filter grade; the catalogue standard is 40 um. The 5 um element is the right choice where downstream valves, cylinders or instruments are sensitive to finer particulate. If your application tolerates coarser filtration, the 40 um version of the same size is available - ask us and we will confirm the correct code.
