The AirTAC GFR600C20AJC2WT 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 GFR600C20AJC2WT is a GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation combined in one body. This size 600 unit is fitted with a 3/4 in NPT port, a 5 um filter element (code W), an automatic drain that ejects collected condensate without manual attention, and an external round gauge reading in psi. 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 the operating temperature range is -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy, and this configuration is supplied without a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options include drain type (differential-pressure, automatic or manual), 40 um or 5 um filtration, gauge style and scale, PT, G or NPT thread, bracket, and a reverse/check valve. Flow is published as curves rather than a single rated figure, 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.

Installed at the drop to a CNC machining cell, this unit removes water and particulate from the shop air line and holds a steady regulated pressure to the machine's pneumatic valves and clamping circuits, with the automatic drain handling condensate between shifts.
Mounted on the air preparation drop feeding a packaging and palletising line, it filters the compressed air before the directional valves and cylinders and keeps actuator pressure stable across the line, protecting the equipment from scale and line rust.
Used on the supply to a laboratory or test-rig pneumatic circuit, the 5 um element gives cleaner air for sensitive instruments and air bearings while the regulator sets the exact test pressure, read directly on the round psi gauge.
Start with the port and size step: this unit is size 600 with a 3/4 in NPT port, the largest step in the GFR range, so match it against the air consumption of the machine or line it will supply. Choose the drain to suit access: automatic (as here) suits installations that are not checked daily, manual suits attended stations, and differential-pressure drain is the catalogue default. Choose the filter grade: 40 um is standard for general plant air, while the 5 um element fitted here suits finer downstream equipment; gauge style and scale (MPa, psi or bar), thread (PT is standard, G and NPT are order options) and bracket are also selectable. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 rather than a single rated figure, so we do not quote one number here. Tell us your application and we will confirm the flow figures from the datasheet on request before you order.
This unit carries drain code A, meaning an automatic drain that discharges collected condensate from the bowl without operator attention - useful for installations that are not checked daily. The catalogue alternatives are manual drain (code M, drained by hand) and differential-pressure drain (blank, the default). The 5 um element (code W) is the other decode choice here, against the 40 um standard element.
