The AirTAC GFR600C20ALJF2 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 GFR600C20ALJF2 is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single 600-size body with a 3/4 in PT port. This configuration is fitted with an automatic drain, so collected condensate is discharged without manual attention; the 40 um standard filter element handles general-purpose air preparation; and the embedded square gauge reads outlet pressure in psi. The regulator is the low-pressure type, and the bowl on this 600-size unit is aluminium alloy. Maximum working (inlet) pressure is 1.0 MPa (145 psi), with an operating temperature range of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is published in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, and options include manual or differential-pressure drains, a 5 um (W) filter element, alternative gauge scales (MPa/psi/bar), G or NPT thread variants and a mounting bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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 a 3/4 in branch take-off from the main header, it filters line water and particulate and holds a steady low-pressure supply to a row of case packers, with the automatic drain clearing condensate between shifts.
Mounted ahead of the solenoid valves on a conveyor system's pneumatic drives, it removes moisture from the shop air and regulates the supply to the low operating pressure the valve stack requires, with the psi gauge giving operators a local reading.
Used as the first stage in a machine's air preparation panel, it conditions the incoming 3/4 in supply and sets the low-pressure regime for downstream pilot circuits, while the automatic drain keeps the aluminium bowl free of accumulated water.
Start with the port step: this unit is 600 size with a 3/4 in PT port, and larger sizes carry larger ports and more flow capacity, so match the size to the air demand of the downstream circuit. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. The automatic drain on this unit suits unattended installations; manual and differential-pressure drain options exist if you prefer operator-controlled or pressure-differential discharge. The 40 um element is the standard grade; specify the W variant for 5 um filtration. The embedded square gauge here reads in psi, with MPa and bar scales and an external round gauge available as options. PT is the standard thread; G (BSPP) and NPT are catalogue order options. This unit ships without a mounting bracket; a bracket is available. The low-pressure regulator type is chosen where the controlled pressure sits below the standard range - confirm the exact adjustment range with us, as it is not published as a single figure for this type.
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 performance curves rather than a single rated figure, so no one flow number can be quoted here. Tell us your line pressure and the air demand of your equipment and we will confirm the correct size and flow figures from the datasheet on request.
The L in the code marks the low-pressure regulator type, intended where the controlled outlet pressure sits below the standard type's range; the exact adjustment range for this type is not published as a single figure, so confirm it with us before ordering. The A marks the automatic drain, which discharges collected condensate from the aluminium bowl on its own instead of waiting for a manual drain operation.
