The AirTAC GFR600C20ALJF2WTK AirTAC Filter Regulator NPT3/4 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 GFR600C20ALJF2WTK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit is threaded NPT3/4, carries a 5 um filter element (code W), and drains condensate automatically. It is the low-pressure regulator type, a square pressure gauge scaled in psi is fitted, and a reverse/check valve is included; no mounting bracket is supplied with this configuration.
It is a genuine AirTAC part from the GFR range, which spans sizes 200 to 600 with ports from 1/8 to 1 in, drain choices (differential-pressure, automatic or manual), 40 um standard or 5 um filtration, and MPa, psi or bar gauge scales. The metal bowl on size 600 units is aluminium alloy. Max working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing. Flow is published only as curves, so ask us to confirm sizing and the datasheet 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.

Filtered, low-pressure-regulated air for actuating capping and filling heads on a beverage bottling line, with the automatic drain keeping condensate away from the downstream valves.
Supplies clean, regulated air to diverter gates and stoppers along a parcel-sort conveyor, with the reverse/check valve holding downstream pressure if the supply dips.
Filtered and pressure-regulated air for spray guns and air-assist nozzles in a paint finishing booth, with 5 um filtration helping protect finish quality from water and particulate carryover.
Size 600 with a 3/4 in port is the largest step in the GFR range; step up or down (200/300/400/600) according to the flow your line needs, and we will confirm the flow curve against your demand. This unit is the low-pressure type (L), so confirm your set pressure with us and we will verify the adjustment range from the datasheet. The 5 um element (W) gives finer filtration than the 40 um standard, and the automatic drain (A) handles condensate without manual attention. Thread here is NPT; PT is the standard build and G (BSPP) is available to order. A square psi gauge is fitted; MPa or bar scales and an external round gauge are options. No bracket is included with this code (J).
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.
Flow for the GFR600 series is published as curves, not as a single rated figure, so we do not quote a number here. Send us your demand (port size, downstream consumption and working pressure) and we will confirm the flow curve and the datasheet for this exact model before you order.
This GFR600 unit is the L version, intended for circuits regulated below the standard type's range. The exact adjustment range for the low-pressure build is not published in our sheet, so confirm your set pressure with us and we will verify suitability from the datasheet.
