The AirTAC GFR60020ALJF3WTK AirTAC Filter Regulator NPT 3/4 in 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 GFR60020ALJF3WTK is a size-600 filter regulator: water and particulate removal plus downstream pressure regulation in a single body. This configuration is fitted with NPT 3/4 in ports, a 5 um filter element (code W, against the 40 um standard), an automatic drain that expels collected condensate without manual attention, and a reverse/check valve. It is the low-pressure regulator type with an embedded square gauge reading in bar, and it is supplied without a mounting bracket. The size-600 bowl is aluminium alloy, and the maximum working (inlet) pressure is 1.0 MPa (145 psi) with an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. GFR filter regulators are available in sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, PT (standard), G or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um filtration, standard or low-pressure regulator types, gauge choices and scale options. Flow is published by AirTAC as curves rather than a single rated figure, so we confirm the datasheet and flow 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.

|---|---|
| 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. |
| 3 | Gauge scale: bar. 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.

Mounted at the drop to a carton-sealing or case-packing section, this unit filters condensed water and fine particles from the shop air, holds a steady low regulated pressure to the sealer cylinders, and its automatic drain keeps condensate off the line without an operator visiting the bowl.
A plasma cutter needs clean, dry, pressure-stable air at the torch. This filter regulator conditions the compressor feed ahead of the machine, the 5 um element protecting torch consumables, while the bar-scale square gauge gives the operator a direct reading of the set pressure.
On a workholding clamp or light pneumatic press circuit, the low-pressure regulator type lets the circuit run at reduced clamping pressure, the reverse/check valve helps hold the downstream side, and the 3/4 in NPT port suits the larger cylinder feeds typical of these machines.
Size 600 is the largest step in the GFR range, pairing the 3/4 in port with the highest flow capacity in the family - size up if your line demand sits near the top of a smaller unit's curve. This model carries the 5 um element (W); choose it where downstream valves and cylinders need finer protection than the 40 um standard, noting finer filtration costs more differential pressure. The automatic drain suits unattended or hard-to-reach installations; manual or differential-pressure drains remain available on other codes. The low-pressure regulator type is intended where setpoints below the standard type's range are needed - the exact adjustment range for this low-pressure variant is not published in our sheet, so confirm it with us against your setpoint before ordering.
Other decodable choices: the embedded square gauge here reads in bar, with MPa or psi scales and an external round gauge available as options; the thread is NPT on this code, with PT (standard) and G offered across the range; and the J code means no mounting bracket is supplied, so plan your own bracket if panel or wall fixing is required. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application 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 GFR series as curves, not as a single rated number, so we do not quote a l/min or SCFM figure for this unit. Send us your line pressure, set pressure and expected air demand, and we will confirm the sizing against the datasheet curves on request before you order.
On the GFR series only the size-600 units use an aluminium alloy bowl; the 200, 300 and 400 sizes use polycarbonate. The A code in this model fits the automatic drain, which discharges collected condensate by itself, so the bowl does not need periodic manual draining - useful where the unit is mounted out of easy reach.
