The AirTAC GFR600C20ALJF2W AirTAC Filter Regulator 3/4 in PT 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 GFR600C20ALJF2W is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This configuration is the size-600 body with a 3/4 in PT port, a 5 um filter element (code W), an automatic drain that clears collected condensate without a manual round, and a low-pressure regulator fitted with an embedded square gauge scaled in psi. At size 600 the bowl is aluminium alloy, and this unit omits the mounting bracket and carries no reverse (check) valve.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, drain choices (differential-pressure, automatic or manual), 40 um standard or 5 um filtration, gauge scale options and G (BSPP) or NPT thread variants to order. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, 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 air prep ahead of a machining centre's valve stack: the 5 um element strips water and particulate before it reaches directional valves, while the low-pressure regulator holds a steady setting for clamps and tool-change cylinders.
Filtered, regulated air for case-packing and carton-sealing cylinders along a packaging conveyor. The automatic drain keeps condensate out of the supply during continuous runs, so no operator has to bleed the bowl mid-shift.
Conditioning the air feeding spray guns in a finishing booth: the 5 um grade limits water and dirt that would spoil the finish, and the low-pressure regulator holds the gun supply at the steady reduced pressure the process calls for.
Step the size and port to the air demand of the circuit: this is the size-600 body with a 3/4 in PT port, the largest step in the GFR range, for lines feeding larger actuators or multiple downstream drops. Drain type is a real choice - the automatic drain fitted here removes condensate unattended, while manual and differential-pressure drains are the alternatives. Filtration is 5 um on this unit (40 um is the standard grade); the gauge is the embedded square type scaled in psi, with MPa or bar scales and an external round gauge available. Thread is PT as standard with G (BSPP) and NPT as order options, and a mounting bracket can be added. Because flow is published as curves and not a single rating, send us your air demand and we will confirm sizing against 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 GFR-series flow as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure and air demand and we will confirm the flow curve and full datasheet for this unit on request.
W is the filter-grade code: 5 um filtration instead of the 40 um standard element. A is the drain code: an automatic drain that ejects collected condensate on its own, instead of the manual or differential-pressure drain options. The L code marks the low-pressure regulator type, and J means no mounting bracket is fitted.
