The AirTAC GFR60020ALJNWTK 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 GFR60020ALJNWTK is an AirTAC GFR600 filter regulator: filtration and pressure regulation combined in a single body. It removes water and particulate down to 5 um (the fine W grade, versus the standard 40 um) and regulates downstream pressure as a low-pressure type. This configuration has a 3/4 in NPT port, an automatic drain that expels collected condensate without manual attention, a reverse/check valve fitted, no gauge supplied, and no mounting bracket. The size-600 bowl is aluminium alloy. 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. GFR filter regulators are published in sizes 200, 300, 400 and 600 with a choice of ports, drain types, filter grades, gauges and threads, so a variant can be matched to your line. Flow is published as curves rather than a single rated figure; 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. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 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. |
| K | Reverse-flow (reflux) valve fitted. |
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, regulated air for the wrapper and cartoner cylinders on a packaging line: the 5 um element protects valve seals from particulate and the automatic drain keeps condensate out of the supply without operator rounds.
A low-pressure regulated air drop feeding bench-top actuators and test rigs in a pilot plant, where the fine 5 um grade and stable reduced pressure matter and the aluminium bowl with auto drain suits an unattended setup.
Supply point for air-driven diverters, gates and stoppers along a conveyor system: the 3/4 in port serves a main drop, the reverse/check valve holds the circuit against backflow, and the automatic drain protects downstream valves.
Size 600 with a 3/4 in port is the largest GFR step, so start there when your line's flow demand sits above what a 1/2 in unit can pass - then verify against the published flow curves, which we will confirm on request, since no single rated figure is stated. The 5 um W element suits actuation and instrumentation that needs finer air than the standard 40 um grade; both grades are available in this family. The automatic drain on this unit handles condensate removal unattended, where a manual-drain unit needs periodic attention and the default differential-pressure drain responds to pressure build-up. No gauge is fitted; a square or round gauge with MPa, psi or bar scale can be ordered. The NPT thread is an order option alongside the PT standard and G (BSPP). No mounting bracket is included with this code, and the low-pressure regulator type means the adjustment range differs from the standard type - confirm the exact range with us before ordering.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR600 series as curves, not as a single rated figure, so we do not state a number here. Tell us your line's flow demand and we will confirm the datasheet curve figures for this exact configuration on request before you order.
The A in the code selects the automatic drain: collected condensate is expelled without manual attention, versus the manual-drain or default differential-pressure drain options. The N selects no gauge, so no pressure gauge is supplied; a square or round gauge with an MPa, psi or bar scale can be ordered as an option. Both are decodable choices, not fixed family traits.
