The AirTAC GFR600C20ALJF2K 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 AirTAC GFR600C20ALJF2K is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 600-size unit is built with a 3/4 in PT port, an automatic drain that discharges collected condensate from the aluminium alloy bowl without operator attention, a 40 um standard filter element, and the low-pressure regulator type. An embedded square gauge scaled in psi is fitted, a reverse (check) valve is built in, and no mounting bracket is included.
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, and options for manual or differential-pressure drains, a 5 um element (code W), alternative gauge scales, G or NPT threads, and brackets. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing. Flow for this family is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application on request.

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.

A 3/4 in filter regulator sits on the main air drop feeding a production hall, cleaning the compressed supply and holding a steady low-pressure setting on the distribution ring.
On a carton-sealing or wrapping line, the unit conditions the air feeding cylinders and grippers, while the automatic drain keeps condensate out of the valves across long shifts.
Feeding a pneumatic clamping fixture, the regulator holds the set pressure while the 40 um element and built-in check valve protect the directional valve from water, debris and backflow.
The real choices within GFR are the size and port step, the drain type, the filter grade, the gauge and its scale, the thread, and the bracket. This unit is already fixed at 600 size with a 3/4 in PT port, an automatic drain, a 40 um element, a square psi gauge, a reverse valve and no bracket; the same series can be ordered in smaller sizes, with manual or differential-pressure drains, a 5 um element, MPa or bar gauge scales, G or NPT threads, and with a bracket. Step size up or down against the flow your line needs - larger sizes carry larger ports and more flow. Because AirTAC publishes flow as curves rather than a single rated number, send us your application details 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 flow for the GFR series as curves rather than a single rated figure, so we do not quote a number here. Send us your operating pressure and air demand and we will confirm the datasheet curve figures for this exact unit on request.
This unit carries code A: an automatic drain that discharges condensate from the aluminium alloy bowl without operator attention. The same GFR600 3/4 in configuration can be ordered with a manual or differential-pressure drain instead, and with a 5 um element (code W) if finer filtration is needed.
