The AirTAC GFR600C20JF3TK 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 GFR600C20JF3TK 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, the standard 40 um filter element, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough. 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), and an embedded square gauge reading in bar is fitted so the set pressure is visible at the unit. A reverse/check valve is included, so downstream pressure is held if the upstream supply drops. Because this is the 600 size, the bowl is aluminium alloy, and the unit is supplied without a mounting bracket. Operating temperature is -5 to 70 C (non-freezing), and the medium is compressed air only.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600, with port options, manual or automatic drains, a 5 um (code W) filter element, gauge scale choices, a low-pressure regulator type, and G (BSPP) or NPT threads in place of the PT standard. 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.

Clean, regulated air for a machining cell's pneumatic clamps, tool changers and chip-ejection cylinders, fed from a 3/4 in shop-air main with the reverse/check valve holding clamp pressure if the supply dips.
Conditioning the air feeding conveyor diverters, case sealers and bagger cylinders on a packaging line, where stable regulated pressure keeps stroke timing consistent across shifts.
Water and particulate removal ahead of bench-mounted test rigs and lab pneumatic circuits, with the bar-scale gauge giving operators a visible set point at each 3/4 in drop.
Start with the port and size: this unit steps up to 3/4 in NPT on the 600 frame, the largest in the GFR range, so match it to your main line diameter and the flow your actuators actually draw. Choose the drain to suit access: this unit uses the differential-pressure drain (default); automatic (code A) or manual (code M) versions exist if you prefer. The 40 um element is standard here; specify 5 um (code W) if downstream equipment needs finer filtration. The fitted square gauge reads in bar; psi and MPa scales and an external round gauge are alternatives. Thread is NPT on this unit (code T); PT is the catalogue standard and G (BSPP) is also available - all are order specifications, not delivery terms. No mounting bracket is included with this configuration (code J). 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 figure here. Send us your line pressure, port size and the equipment you are feeding, and we will confirm the flow figures from the datasheet for this exact unit before you order.
K means a reverse (check) valve is fitted. It holds pressure on the downstream side if the upstream supply drops, which is useful on circuits where a momentary supply loss would otherwise let a regulated setting or a clamped load release. Units without the K code do not include this valve.
