The AirTAC GFR60020ALJC1WT 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 GFR60020ALJC1WT is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration carries a 3/4 in NPT port, a 5 um filter element (code W) for finer protection than the standard 40 um grade, and an automatic drain that expels collected condensate without anyone opening a valve. The regulator is the low-pressure type (code L), a round pressure gauge scaled in MPa is fitted, and as a size 600 unit the 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. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of 40 um standard or 5 um filtration, differential-pressure, automatic or manual drains, gauge and thread options, and standard or low-pressure regulation. AirTAC publishes flow 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.
| 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. |
| 1 | Gauge scale: MPa. 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, pressure-reduced air to pneumatic clamps and vises on a machining centre: the 5 um element protects directional valves and the automatic drain keeps condensate out of the clamp circuit during long runs.
Supplying clean, regulated air to pick-and-place cylinders and grippers on a packaging conveyor, where the automatic drain suits unattended shifts and the low-pressure type matches circuits run below standard line pressure.
Providing filtered, reduced-pressure air to actuate pneumatic control valves on a chemical or water-treatment skid, with the 5 um grade guarding pilot valves and the MPa gauge giving operators a local pressure readout.
Size and port: GFR600 is the largest G-series size with a 3/4 in NPT port; smaller sizes 200/300/400 step down in port and flow, so match the published flow curves to your demand - ask us to check sizing before ordering. Drain: this unit has the automatic drain; manual and differential-pressure drains are the alternatives on the family. Filtration: the 5 um element here (code W) suits finer downstream components; 40 um is the standard grade. Gauge: a round gauge scaled in MPa is fitted; the embedded square gauge and psi or bar scales are options. Thread: NPT is ordered as an option - PT is the standard thread and G (BSPP) is also available. This unit is ordered without a mounting bracket (code J); brackets are optional. Regulation: this is the low-pressure type (L); its exact adjustment range is not published in our data, so confirm it with us before ordering.
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 rather than a single rated figure, so we do not quote a number here. Send us your downstream demand and working pressure and we will confirm the flow and datasheet figures for this unit on request.
The automatic drain on this unit expels collected condensate on its own, which suits unattended lines and multi-shift operation. The GFR family also offers a manual drain for points someone checks daily, and a differential-pressure drain as the default; all three are order-time choices, not site modifications.
