The AirTAC GFR60020ALJC2WG AirTAC Filter Regulator G3/4, 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 AirTAC GFR600 series combines water and particulate filtration with pressure regulation in a single body, so one component both cleans the compressed air and sets the downstream pressure. This configuration is the size 600 unit in G3/4 (BSPP) thread, fitted with a 5 um filter element (code W) for finer particle capture than the standard 40 um grade, an automatic drain that expels collected condensate without manual attention, the low-pressure regulator type, and an external round gauge reading in psi. The bowl on this size 600 unit is aluminium alloy, and the unit is ordered without a mounting bracket. 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 filter-regulator family spans sizes 200, 300, 400 and 600, with port options from 1/8 to 1 inch, PT as the standard thread and G or NPT available as order options, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, standard or low-pressure regulation, and gauge or no-gauge variants. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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. |

| C | Gauge shape: Round. 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. |
| G | G (BSPP) 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.

Mounted at the drop of a bottling hall's main air ring, the unit filters water and fine particles from the supply and holds a steady reduced pressure to the wrapper and capper cylinders, while the automatic drain clears condensate on a line that runs unattended between shifts.
On weaving and spinning machines fed from a plant ring main, the 5 um element protects sensitive jet and valve components from particulates carried in the compressed air, and the low-pressure regulator type sets the moderate circuit pressure the machine's pneumatics are designed around.
On a laboratory or QC test rig supplied from the workshop compressor, the unit cleans the air to 5 um and regulates it to the pressure the bench instruments expect, with the round psi gauge giving a direct local reading and the automatic drain keeping the aluminium bowl clear.
Start with the port step: size 600 in G3/4 suits lines where larger supply piping is already in place, and the right size depends on the flow your circuit needs rather than the pipe alone. Choose the drain to match maintenance reality: automatic drain (this unit) suits points that are hard to reach or run unattended, manual drain suits attended stations, and differential-pressure drain is the catalogue default. Choose the 5 um element (this unit) when downstream valves or instruments need finer filtration than the standard 40 um grade. The external round gauge in psi (this unit) is an alternative to the embedded square gauge, which is also available in MPa or bar scales. Thread is G (BSPP) here, with PT standard and NPT orderable; brackets are optional and not included on this code. Because flow for this series is published as curves and not as a single rated figure, send us your application details 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 number. Tell us your application and required flow, and we will confirm the sizing against the datasheet on request before you order.
The automatic drain expels collected condensate by itself, which suits installations that are awkward to reach or left running without an operator, unlike the manual or differential-pressure drain options. The 5 um element (code W) filters more finely than the standard 40 um grade, which is the better choice when protecting sensitive downstream valves or instruments.
