The AirTAC GFR600C20AJC2WTK 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 AirTAC GFR600C20AJC2WTK is a GFR-series filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This 600-size unit is built with 3/4 in NPT ports, a 5 um filter element (the finer of the two catalogue grades), an automatic drain that ejects collected condensate without daily attention, a round external gauge reading in psi, and a built-in check valve that helps hold downstream pressure if the upstream supply dips. It is supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the regulating range is 0.15-0.9 MPa (20-130 psi), the working temperature span is -5 to 70 C (non-freezing), and the 600-size bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and can be ordered with manual or differential-pressure drains, the 40 um standard element, an embedded square gauge or an external round gauge in MPa, psi or bar scales, G (BSPP) or NPT threads in place of the PT standard, and with or without a bracket. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet 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.

Filters and regulates the supply feeding spray guns and air balances in a paint booth, with the automatic drain clearing accumulated condensate between shifts so no one has to bleed the bowl by hand.
Sits upstream of the cylinders and flap tuckers on a packaging conveyor, holding a steady set pressure so case-erecting and sealing cycles stay repeatable across the whole line.
Supplies filtered, regulated air to the clamping cylinders on a machining-centre fixture, with the fitted check valve helping hold clamp pressure if the shop main supply dips mid-cycle.
Work through the decodable choices in order. Size and port: this is the largest GFR step, size 600 with a 3/4 in port; if your line's air demand is modest, a 300 or 400 in a smaller port may suit better - match the size step to required flow, which we confirm from the catalogue curves rather than a single rating. Drain: this unit is automatic, the right choice where the bowl cannot be checked daily; manual drain suits attended installations and differential-pressure drain triggers service off element loading. Filter grade: 5 um here against the 40 um standard - choose 5 um for instruments and finer pneumatic equipment. Gauge: an external round gauge on a psi scale; the embedded square gauge and MPa or bar scales are the alternatives. Thread: NPT on this code, with G (BSPP) or the PT standard available to order. A mounting bracket is omitted on this code, so plan your own panel or frame fixing.
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 curves rather than a single rated figure, so we do not quote a number here. Tell us your inlet pressure, set pressure and air demand and we will confirm the flow from the datasheet on request.
The A in the code selects the automatic drain, which ejects condensate without daily manual bleeding, and W selects the 5 um element instead of the 40 um standard - a pairing suited to unattended lines running instruments or finer pneumatic equipment. Manual-drain and 40 um versions are available in the same size.
