The AirTAC GFR600C20JF2GK AirTAC Filter Regulator G3/4 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 GFR series combines filtration and pressure regulation in a single body: it strips water and particulate from compressed air and holds downstream pressure at a set value. This GFR600C20JF2GK is the size 600 unit with a G3/4 (3/4 in) G-thread port, the standard 40 um element, a differential-pressure drain that bleeds collected water as air passes through, an embedded square gauge reading in psi, and a reverse/check valve fitted so downstream pressure is held if the supply drops. The bowl on this largest frame is aluminium alloy, inlet pressure is rated to 1.0 MPa (145 psi), operating temperature is -5 to 70 C non-freezing, and the unit is supplied without a mounting bracket.
This is a genuine AirTAC part. The GFR range spans sizes 200 to 600 with ports from 1/8 in to 1 in, and options include manual or automatic drains, a 5 um element (code W), MPa or bar gauge scales, an external round gauge, NPT thread and a mounting bracket. Flow is published as curves rather than a single rating, so ask us to confirm the sizing figures from the datasheet for your application.

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 spray-booth and air-balance circuits on an automotive paint line, where the 40 um element strips water and pipe scale and the regulator holds a steady setting so spray pressure does not drift through a shift.
Supplying the gripper and clamp cylinders on a carton-forming conveyor, where the reverse/check valve holds the downstream circuit if plant air dips and the psi gauge lets operators verify setpoints at a glance.
Conditioning the supply to a CNC machining centre's tool-change and clamping circuits, where stable regulated pressure supports consistent clamp force and the differential-pressure drain carries condensate away without daily manual draining.
Choose the size by port and flow: this size 600 unit carries a G3/4 (3/4 in) G-thread port, the largest step in the range, for lines where smaller ports would restrict flow. The standard 40 um element suits general plant air; specify the W code for 5 um when finer protection is needed. The differential-pressure drain is the no-settings default, with automatic and manual drains as orderable alternatives. Regulation spans 0.15-0.9 MPa (20-130 psi) with this drain type, and the fitted square gauge reads psi; MPa and bar scales and an external round gauge are options. Thread is G here, with PT and NPT orderable, and a bracket can be added. Flow is published as curves, not a single rating, so send us your flow and pressure requirement and we will confirm sizing from 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 GFR600 flow as performance curves rather than a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm the sizing from the datasheet on request.
The K in GFR600C20JF2GK means a reverse/check valve is fitted, so air does not flow back through the unit if upstream pressure is lost. It is a decodable option on GFR units; models without the K code do not include it. Ask us if you would prefer the version without it.
