The AirTAC GFR60020ALJF2W AirTAC Filter Regulator 3/4 in PT 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 GFR60020ALJF2W is an AirTAC GFR600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure at a set point, in a single body. This unit is built on the 600 size with a 3/4 in PT port, and it carries the 5 um filter element (code W) instead of the standard 40 um, an automatic drain that ejects collected condensate without manual attention, the low-pressure regulator type, and a fitted square gauge scaled in psi. At size 600 the bowl is aluminium alloy, and this configuration comes without a mounting bracket.
It 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), filter grades of 40 um standard or 5 um optional, standard or low-pressure regulation, an embedded square gauge (MPa, psi or bar scales) with an optional external round gauge, and PT, G or NPT threads. 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 figures 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. 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.

|---|---|
| 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). |
| F | Gauge shape: Square. 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. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |

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.

On a bottling plant's 3/4 in main drop, the GFR60020ALJF2W strips water and fine particles before the air reaches actuated fill and capping valves, and holds a steady set pressure so cylinder strokes stay consistent across the shift.
Where a process circuit - a powder-dosing skid, a coating line's air knife or a vacuum ejector supply - runs below the pressures a standard regulator is set up for, the low-pressure type (L) is the decodable choice, with the psi-scaled square gauge giving operators a direct read of the set point.
In a plant air takeoff nobody drains by hand - a weekend-shift saw cell or an outdoor rig - the automatic drain removes accumulated condensate on its own, while the 5 um element protects downstream valves, cylinders and gauges from fine contamination.
Sizing starts at the 600 size and its 3/4 in PT port: step up or down through the 200/300/400/600 range against the flow your line needs - flow is published as curves rather than one rated figure, so send us your demand and we will confirm the right size before you order. The remaining choices are all decodable from the code: the 5 um element (W) for finer particulate control versus the standard 40 um; the automatic drain, which suits takeoffs nobody drains on a schedule, versus manual or differential-pressure drains; the low-pressure regulator type (L), whose exact adjustment range is not published, versus the standard type; the square gauge scaled in psi (MPa and bar scales are available); the PT thread, with G (BSPP) and NPT as order options; and the mounting bracket, which this code omits (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.
AirTAC publishes filter-regulator flow as curves, not as a single rated number, so we do not quote a figure here. Tell us your operating pressure and air demand and we will confirm the sizing against the datasheet on request.
The A in the code sets the automatic drain: condensate is ejected without manual attention, which suits takeoffs that are not drained on a schedule. The W sets the 5 um element instead of the standard 40 um, for finer particulate removal ahead of sensitive valves and instruments. The same code also decodes the low-pressure regulator type (L) and the psi-scaled square gauge (F2), and the J means no mounting bracket is included.
