The AirTAC GFR600C20AJF2WT AirTAC Filter Regulator NPT 3/4 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 AirTAC GFR600C20AJF2WT is a size-600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in one body. This configuration has 3/4 in NPT ports, a 5 um filter element (the finer of the two published grades), an automatic drain that ejects collected condensate without manual attention, and an embedded square gauge reading in psi. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy, and no mounting bracket is fitted on this variant.
This is a genuine AirTAC part. The GFR filter-regulator line spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and is ordered with your choice of drain type (differential-pressure, automatic or manual), filter grade (40 um standard or 5 um), gauge type and scale, thread form (PT standard, with G and NPT as order options), bracket and reverse/check valve. Flow is published as curves rather than a single rating, so ask us and we will confirm the flow and 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.

Positioned at the drop feeding a CNC machine's pneumatic valves and clamps, this unit strips water and fine particles from the shop air and holds a steady regulated pressure so tool-change and clamping actions stay repeatable through the shift.
On a carton-forming and sealing line, the GFR600C20AJF2WT feeds the cylinders and air-driven sealers with cleaned, regulated air at 3/4 in scale, while the automatic drain keeps condensate out of the circuit without an operator stopping to bleed the bowl.
Ahead of lab automation manifolds and pneumatic sample handlers, the 5 um element removes fine particulate that could disturb sensitive components, and the psi-scaled square gauge gives technicians a direct read of the regulated supply pressure.
Size and port set the capacity of the unit: 600 is the largest GFR frame, and the 3/4 in NPT port here suits lines fed at that scale. Match the frame to your flow demand - but note that AirTAC publishes flow as curves, not a single rated figure, so send us your application details and we will confirm sizing against the datasheet before you order. The remaining choices are all decodable: drain type (automatic here, so condensate is expelled without intervention; manual and differential-pressure drains are alternatives), filter grade (5 um on this unit versus the 40 um standard), gauge (embedded square, psi scale; an external round gauge in MPa, psi or bar is optional), thread form (NPT here; PT is the standard catalogue thread and G is also available), and bracket (not fitted on this variant, available as an option).
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 rather than a single rated figure, so we do not quote a rated flow number. Tell us your application and operating pressure and we will confirm the flow and datasheet figures for this exact model on request.
The code spells it out: W selects the 5 um filter grade instead of the 40 um standard, and A selects the automatic drain, which expels collected condensate on its own instead of relying on a manual or differential-pressure drain. Both choices are order options across the GFR range, so you can specify the combination that suits your line.
