The AirTAC GFR600C20ALJF2WK AirTAC Filter Regulator PT3/4, 5 um 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 GFR600C20ALJF2WK is an AirTAC GFR600 filter regulator: filtration and pressure regulation combined in a single body. It removes water and particulate from compressed air through a 5 um element (the W grade; 40 um is the standard alternative) and regulates downstream pressure as a low-pressure type unit. This configuration has PT3/4 ports, an automatic drain that ejects collected condensate without manual attention, an embedded square gauge reading in psi (an external round gauge is optional), a built-in reverse/check valve, and no mounting bracket. The size 600 bowl is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. GFR600 is the largest size in the GFR range, which steps through 200, 300, 400 and 600 with matching port sizes, and is available with manual, automatic or differential-pressure drains, 40 um or 5 um filtration, square or round gauges in MPa, psi or bar scales, G or NPT thread options, and with or without a bracket. Flow is published as curves rather than a single rating, so ask us to confirm the 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.

Points the regulated, water- and particulate-filtered air feeding jet nozzles and pneumatically tensioned guides on a weaving line, where stable low-pressure supply at a 3/4 inch main keeps the loom sequence running.
Conditions and regulates the air driving pushers, diverters and clamp cylinders along a carton packaging conveyor, with the 5 um element protecting valve spools from moisture and fine debris.
Sits ahead of a fill-and-capper valve manifold on a bottling line, filtering the plant air to 5 um and holding the reduced pressure the manifold actuators were set up for, with automatic drain handling condensate.
Start with the port step: GFR600 carries PT3/4 ports, the largest in the range, so size up to 600 when your line runs at 3/4 inch and step down to GFR200/300/400 for smaller ports and lower air demand. Choose the drain to match access: automatic (this unit) suits installations that are not checked daily; manual drain suits attended stations; differential-pressure drain is the default. Choose 5 um filtration (this unit) where downstream valves, cylinders or instruments need finer air than the 40 um standard element provides. This is the low-pressure (L) regulator type; its exact adjustment range is not published on our sheet, so confirm it with us if your set pressure is critical. The square gauge here reads psi; MPa and bar scales and an external round gauge are alternatives. Thread is PT as standard, with G (BSPP) and NPT orderable as catalogue options. A bracket is optional - this configuration omits it.
Because flow is published only as curves and not as a single rated figure, 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 this series as curves, not as a single rated figure, so we do not quote a number. Tell us your application and operating conditions and we will confirm the relevant flow and datasheet figures for you before you order.
The A in the code specifies an automatic drain, which ejects collected condensate from the aluminium alloy bowl without anyone opening it - useful for units mounted high or on lines that run unattended. The GFR600 is also orderable with a manual drain or the default differential-pressure drain if that suits your maintenance routine better.
