The AirTAC GFR60020AJC1WTK AirTAC Filter Regulator 3/4 in NPT is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/4" ports, a automatic 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 GFR60020AJC1WTK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is fitted with a 5 um filter element (the finer of the two catalogue grades), an automatic drain that discharges collected condensate without manual attention, a round pressure gauge with an MPa scale, and a reverse (check) valve. The port is 3/4 in NPT thread, and the aluminium alloy bowl suits this largest size in the range. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range with automatic drain is 0.15-0.9 MPa (20-130 psi), and the operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600, with port sizes from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, square or round gauges with MPa, psi or bar scales, and an optional low-pressure regulator type. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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.

Drops a 3/4 in branch off the plant air ring to feed a CNC machining cell, drying and cleaning the air and holding a set regulator pressure for the cell's pneumatic valves and clamps. The automatic drain keeps condensate off the floor in an unsupervised corner of the shop.
Feeds the cylinder and gripper manifold on a carton packaging line, where the 5 um element protects fine control valves from particulate and the regulator holds a steady pressure so case-ejector strokes stay repeatable through the shift.
Serves the 3/4 in drop feeding air hose reels in a truck or bus maintenance bay, giving technicians filtered, regulated air for impact wrenches and inflation, with the check valve holding the downstream setting while the compressor cycles.
Start with the port step: this unit is the size 600 body with 3/4 in NPT thread, the largest size in the GFR range, so match it to your line size and the flow your application needs. Choose the drain type for your duty: automatic drain (fitted here) suits unattended or hard-to-reach installations, manual drain suits supervised points, and differential-pressure drain is the catalogue default. Choose the filter grade: 40 um is standard for general protection, 5 um (fitted here) for finer downstream protection. Gauge and scale are selectable (square embedded or round external; MPa, psi or bar), and a reverse/check valve can be ordered where the downstream circuit needs it. Thread is PT as standard with G and NPT as order options, and a mounting bracket is optional (this code omits it). Because flow is published as curves rather than a single rating, 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR flow as curves rather than a single rated figure, so we do not quote a rated l/min, m3/h or SCFM number. Send us your inlet pressure, set pressure and required flow, and we will confirm the sizing against the datasheet curves on request before you order.
The code decodes A as an automatic drain (it discharges condensate without manual attention, where manual and differential-pressure drains are the other catalogue choices), K as a fitted reverse/check valve, W as the 5 um filter element, C1 as a round gauge with an MPa scale, and J as no mounting bracket. All of these are orderable options, so a differently coded GFR600-20 can be supplied with a manual drain, no check valve, the 40 um element, a psi or bar scale, or a bracket included.
