The AirTAC GFR600C20AJF2GK AirTAC Filter Regulator G3/4 Auto Drain 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 GFR600C20AJF2GK is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure at your setpoint. This size 600 unit has a G3/4 (BSPP) port, an automatic drain that discharges collected condensate without manual attention, a 40 um standard filter element, an embedded square gauge reading in psi, and a built-in check valve that helps hold downstream pressure when upstream supply drops. The bowl on the 600 frame is aluminium alloy, maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). No mounting bracket is fitted with this code.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600, with manual and differential-pressure drain alternatives, a 5 um element (code W), gauge scales in MPa, psi or bar, an external round gauge option, PT standard or G/NPT threads, and bracket choices. 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.

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 filtered, regulated air for the pneumatic clamps and tool-change cylinders on a CNC machining centre, with the automatic drain clearing condensate at the machine without operator rounds.
Clean, pressure-stable supply to spray guns in an automotive refinish booth; the 40 um element knocks out water and pipe scale that would otherwise spoil a finish, while the regulator holds gun pressure steady.
Regulated supply to the diverter and gate cylinders on a packaging conveyor, with the fitted check valve helping hold downstream pressure through upstream dips so divert strokes stay consistent.
Choose the size and port against the air your line actually uses: 600 is the largest step in the GFR range, and this code carries it at G3/4 with G (BSPP) thread - PT is the standard thread and NPT is also orderable. Drain type matters: automatic (this unit) needs no routine draining, while manual and differential-pressure versions exist; note that automatic and differential-pressure drain units adjust 0.15-0.9 MPa (20-130 psi) while manual-drain units reach down to 0.05 MPa (7 psi). The 40 um element is standard; specify code W for 5 um where finer particulate removal is needed. The square psi gauge is fitted here, and MPa or bar scales, or an external round gauge, can be ordered instead. Flow is published as curves, not a single rating, so send us your flow and pressure requirements 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 flow for the GFR series as curves rather than a single rated figure, so we do not quote one number. Tell us your required flow and working pressure and we will confirm the sizing from the datasheet on request.
The automatic drain ejects collected condensate on its own, so the bowl does not need routine manual draining. Drain type also sets the regulator span: automatic and differential-pressure drain units adjust 0.15-0.9 MPa (20-130 psi), while manual-drain units adjust 0.05-0.9 MPa (7-130 psi).
