The AirTAC GFR60020ALJC2WT AirTAC Filter Regulator NPT3/4, 5 um is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/4" ports, a automatic 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 GFR60020ALJC2WT is a size 600 filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This configuration carries a 3/4 in NPT port, a fine 5 um filter element (the 40 um standard element is the alternative), an automatic drain that expels collected condensate without manual attention, and the low-pressure regulator type. It is fitted with an external round gauge scaled in psi, and the size 600 bowl is aluminium alloy. No mounting bracket is included with this code. 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. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, in PT (standard), G and NPT threads, with a choice of drain type, filter grade, gauge style and scale, low-pressure or standard regulator, and optional reverse/check valve. Flow 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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.

Feeds cleaned, regulated air to the solenoid valve manifold of a carton-forming or wrapping machine, with the 5 um element protecting spool clearances and the automatic drain keeping the bowl clear through long shifts.
Serves as the single filter-regulator point ahead of a multi-cylinder pick-and-place station, setting one stable supply pressure for grippers and slides while the round psi gauge gives operators a direct read.
Regulates the air feeding diverters, stoppers and lifters along a conveyor line, where the low-pressure regulator type and automatic drain suit lines run at reduced pressure around the clock.
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 air demand of the line, and ask us to check the published flow curve against your consumption before ordering. Drain type is a real choice: automatic (this code) empties the bowl on its own, while manual and differential-pressure drains suit other service routines. Filter grade is 5 um here versus the 40 um standard element - choose 5 um where downstream valves and instruments need finer protection. The gauge is external round, psi scale; embedded square gauges and MPa or bar scales are the other options. Thread is NPT; PT is the catalogue standard and G is also orderable. This code omits the mounting bracket and the reverse/check valve; both are available in sibling codes.
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 flow as curves, not as a single rated number, so we do not quote a l/min or SCFM figure. Send us your line pressure and air consumption and we will confirm the datasheet curve and sizing for this 3/4 in, size 600 unit on request.
Both are decoded from the code: A is the automatic drain, which expels condensate by itself instead of waiting for a manual or differential-pressure drain cycle, and W is the 5 um filter grade, one step finer than the 40 um standard element. Manual-drain and 40 um versions of the same size 600 unit exist if your service routine differs.
