The AirTAC GFR600C20JC3TK AirTAC Filter Regulator 3/4 in NPT 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 GFR600C20JC3TK is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady between 0.15 and 0.9 MPa (20-130 psi). This size-600 unit is specified with a 3/4 in NPT port, the standard 40 um filter element, a differential-pressure drain, an aluminium alloy bowl, a round pressure gauge reading in bar, and a built-in reverse (check) valve; no mounting bracket is fitted. It handles a maximum inlet pressure of 1.0 MPa (145 psi) at -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR range, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, optional 5 um filtration (code W), automatic or manual drains, G and NPT thread options, and a choice of gauge scales. Flow for this unit is published as a curve rather than a single rating, so ask us to confirm sizing figures from the datasheet 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.

Point-of-use conditioning on assembly-line air drops: water and pipe scale are stripped out at the station while the regulator holds tool supply pressure steady through the shift.
Feeding clean, regulated air to pneumatic clamps and tool-change cylinders on a machining centre, with the built-in check valve holding the downstream circuit if supply pressure dips.
Conditioning air to carton-sealing and labelling cylinders on a packaging conveyor, where a stable regulated pressure keeps stroke timing consistent from station to station.
Within GFR600 the real, decodable choices are the port step (3/4 in here, with other sizes elsewhere in the range), the filter grade (40 um standard, 5 um with code W), the drain type (differential-pressure as fitted here, or automatic or manual), the gauge (embedded square standard, external round optional, in MPa, psi or bar scales) and the thread (PT is the catalogue standard; G and NPT are order options). Bracket inclusion is also a code choice, and this unit omits it. Flow is published as curves, not a single rated figure, so send us your application parameters 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 GFR flow as performance curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure, downstream set pressure and required air consumption, and we will confirm the sizing from the datasheet on request.
The C3 code on this model specifies the optional external round gauge with a bar scale (MPa and psi scales are also available), and the T code specifies NPT threads; PT is the catalogue standard thread, with G and NPT available as order options. Both are specification choices you select when ordering.
