The AirTAC GFR60020ALJF2WT AirTAC Filter Regulator NPT3/4 Low-Pressure 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 GFR60020ALJF2WT is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built for 3/4 in NPT ports, carries the 5 um filter element (code W) for finer filtration than the standard 40 um grade, and drains condensate automatically, so the bowl does not depend on someone opening a manual drain. It is the low-pressure regulator type, and the embedded square gauge is fitted with a psi scale for direct local pressure reading. The bowl on this size is aluminium alloy, and no mounting bracket is included.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, standard or low-pressure regulation, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.
| 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). |
| 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. |
| 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.

Feeding filtered, regulated air to case packers, carton sealers and wrapping machines on a packaging line, with automatic condensate draining so the unit keeps working through long unattended shifts.
Conditioning the air supply to a pneumatic press or clamping station, where the 5 um element helps protect directional valves and cylinders from water and fine particulate carryover.
Serving as the filter-regulator stage for a multi-circuit assembly cell, giving each cell a local psi gauge for setting and checking working pressure at the machine.
Size 600 with a 3/4 in NPT port sits at the top of the GFR range, so step up or down (200/300/400/600) according to the air demand of the line rather than the pipe size alone. Choose the 5 um element (this unit) where downstream valves, cylinders or instruments need finer air than the standard 40 um grade; the automatic drain suits unattended or hard-to-reach installations, while manual and differential-pressure drains remain available in the series. The low-pressure regulator type is the right pick when the working pressure sits below the standard regulator's usual span. The fitted square gauge reads in psi; MPa and bar scales and an external round gauge are the other catalogue options. NPT is an order option alongside the PT standard and G (BSPP); brackets are optional on this family and are not fitted here. Because flow is published as curves and not a single rating, send us your air demand and we will confirm sizing against the datasheet before you order.
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 flow for the GFR series as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your air demand and line conditions and we will confirm the sizing against the datasheet on request before you order.
The W code in the model sets the 5 um filter element instead of the standard 40 um grade, giving finer removal of particulate and water for sensitive downstream equipment. The A code sets the automatic drain, which expels collected condensate by itself instead of relying on a manual drain valve being opened.
