The AirTAC GFR600C20AJF1WTK 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 AirTAC GFR600C20AJF1WTK is a 600-size filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is threaded NPT3/4 (3/4 in), carries the fine 5 um filter element (the 40 um standard element is the alternative), and has an automatic drain that bleeds collected condensate from the bowl without manual attention. The 600-size bowl is aluminium alloy. A square pressure gauge (MPa scale) is fitted so the set pressure is visible, and a reverse/check valve is fitted to hold downstream pressure if the supply drops. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range for this automatic-drain version is 0.15-0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). No mounting bracket is included in this version.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with matching port sizes, and is available with manual, automatic or differential-pressure drains, 40 um or 5 um filtration, PT, G or NPT threads, with or without gauge, bracket or check valve. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and flow 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.

Installed at the take-off from a factory compressed-air ring main, it cleans the supply of water and scale and holds a steady regulated pressure for the downstream drop.
Feeding cylinders and air actuators on a packaging or conveyor line, it keeps moisture and fine particles out of the valves while holding the working pressure the actuators were set up for.
On a test bench or pilot rig supplied from a shared compressor, the 5 um element and fitted MPa gauge give visibly set, filtered air for instruments and test fixtures.
Size and port are the first choice: 600 is the largest GFR size, with a 3/4 in port here, and the right step depends on the air demand of the line it feeds. Drain type matters in practice: automatic drain (this unit) suits unattended or hard-to-reach installations, manual drain suits stations visited routinely, and differential-pressure drain is the catalogue default. The 5 um element (code W) is the finer choice over the 40 um standard when downstream equipment needs cleaner air. The fitted square gauge reads in MPa; psi and bar scales and an external round gauge are the other gauge options. Thread is NPT here, with PT as the standard and G (BSPP) as the alternative order option. A check valve is fitted in this code, and no bracket is included, though brackets are optional across the family.
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated number, so we do not quote a flow figure here. Send us your application's air demand and we will confirm the correct size and the datasheet figures 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 figure, so we do not quote a number here. Tell us your application's air demand and we will confirm the datasheet and flow-curve figures for this 600-size, 3/4 in unit before you order.
The W in the code selects the finer 5 um filter element instead of the 40 um standard, and A selects the automatic drain, which ejects collected condensate on its own instead of waiting for a manual bowl drain. Both are catalogue options on the GFR family; the 40 um element and manual or differential-pressure drains are available if your station suits them better.
