The AirTAC GFR600C20AJC3WTK 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 GFR600C20AJC3WTK is an AirTAC GFR600 filter regulator: water and particulate filtration plus pressure regulation combined in a single 600-size body. This configuration is threaded NPT3/4, carries a 5 um filter element (grade code W) for finer particle removal than the 40 um standard element, and drains condensate automatically from the bowl, which at size 600 is aluminium alloy. The standard-type regulator adjusts from 0.15-0.9 MPa (20-130 psi), a round pressure gauge reading in bar is fitted, and a reverse/check valve (code K) is built in. No mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR filter-regulator line runs from size 200 through 600, with a choice of port size, drain type (differential-pressure, automatic or manual), filter grade (40 um standard or 5 um), gauge style and scale, thread form (PT standard, G or NPT to order) and bracket option. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application.

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.

Installed at the take-off from a packaging plant's compressed-air main, it strips water and fine particles from the supply and holds a steady regulated pressure to the hall's pneumatic circuits.
Feeding the air cylinders that index and stop bottles on a bottling-line conveyor, the 5 um element protects the cylinders from fine debris while the regulator keeps cylinder speed consistent.
Mounted ahead of a bank of directional control valves on an assembly line, it delivers clean, regulated air so the valves shift reliably shift after shift; the fitted check valve holds the setting against supply dips.
Step up through sizes 200, 300, 400 and 600 to match the port and the flow your line needs; this 600-size unit sits at the top of the range with a 3/4 in port. Choose the drain to suit maintenance access: automatic drains condensate on its own, manual needs a routine visit, and the differential-pressure default drains only when the pressure differential calls for it. Pick the element grade for the downstream tolerance: 40 um standard or 5 um (W) where finer protection matters. Gauge style and scale (MPa, psi or bar) and thread form (PT standard, G or NPT as order options) are specified in the code, as is the bracket choice; this code omits the bracket.
Because flow is published as curves and not as a single rated figure, 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 as curves rather than a single rated figure, so there is no one number we can honestly quote. Tell us your operating pressure and air demand and we will confirm the flow from the datasheet curves on request before you order.
In the code GFR600C20AJC3WTK, the W sets the 5 um filter grade instead of the 40 um standard element, and the A sets an automatic drain instead of the differential-pressure default. The C3 gives a round gauge reading in bar, T sets the NPT thread instead of the PT standard, J omits the bracket, and K fits a reverse/check valve.
