The AirTAC AirTAC GFR60020JC2WTK Filter Regulator NPT3/4 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 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 GFR60020JC2WTK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit is specified with a 3/4 in NPT port, a 5 um filter element (the finer of the two available grades), a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough, and a round pressure gauge reading in psi. A reverse/check valve is fitted, and the unit is supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the regulation range is 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C (non-freezing). The bowl on this size 600 unit is aluminium alloy.
This is a genuine AirTAC part. The GFR filter-regulator family is available in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um fine filtration, embedded square or external round gauges with MPa, psi or bar scales, an optional low-pressure regulator type, an optional reverse/check valve, and PT (standard), G or NPT threads. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Feeding clean, regulated air to the wrapper and case-sealer cylinders on a carton packaging line, with the 5 um element protecting valve spools and the psi gauge giving operators a visible setpoint.
Conditioning the supply to a machining centre's pneumatic clamping circuit, where the regulator holds steady clamp pressure and the check valve keeps clamps engaged if upstream air drops.
Supplying the diverters, stops and pusher cylinders along a distribution conveyor, with the differential-pressure drain keeping condensate out of the actuators without daily manual draining.
Size 600 with a 3/4 in NPT port is the largest step in the GFR range; step up or down through sizes 200/300/400/600 according to the flow your line needs, and confirm the match against the published flow curves before ordering. Drain choice here is the differential-pressure type (the default), which needs no manual attention but only purges when the element differential is sufficient; automatic (code A) and manual (code M) drains are available if your duty calls for them. The 5 um element (code W) suits downstream equipment that needs finer filtration than the 40 um standard grade. The fitted round gauge reads in psi; embedded square gauges and MPa or bar scales are the other gauge options. PT is the standard thread, with G and NPT as orderable options - this unit is built with NPT. A bracket can be added if you need panel or wall mounting (this configuration omits it), and the reverse/check valve fitted here holds downstream pressure on upstream supply loss.
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 flow for the GFR series as curves, not as a single rated number, so there is no one figure we can quote honestly. Tell us your operating pressure and the flow your application needs, and we will confirm the sizing against the datasheet curves on request before you order.
This configuration uses the differential-pressure drain (the default), which discharges collected condensate automatically when the pressure drop across the 5 um element rises - no operator action needed, but it only purges under sufficient differential. If you want continuous automatic purging regardless of differential, choose the automatic drain (code A); if you prefer a simple, operator-drained bowl, choose manual (code M).
