The AirTAC GFR60020ALJC2W AirTAC Filter Regulator PT3/4, 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 GFR60020ALJC2W 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 a 3/4 in PT port, carries the fine 5 um filter element (code W), drains condensate automatically, and is the low-pressure regulator type. The bowl on this size is aluminium alloy, an external round gauge with a psi scale is fitted, 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 to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge and thread options, and standard or low-pressure regulator types. Flow is published as curves rather than a single rated figure, so 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. |
| (blank) | Pressure gauge fitted (blank). |
| 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. |
| (blank) | PT 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.

Point-of-use conditioning ahead of air-jet nozzles on a weaving line, where the 5 um element protects jet orifices from water and particulate and the low-pressure regulator holds a gentle supply pressure.
Filtered, regulated air feeding clamp cylinders on a CNC fixture line, with the automatic drain keeping condensate out of valves and the psi gauge giving operators a readable setpoint.
Conditioning the air stream that drives low-pressure actuators and air cylinders on a cartoning or wrapping machine, where the 3/4 in port serves a higher-flow branch of the distribution grid.
Step up or down through the GFR sizes (200/300/400/600) to match the port and flow path your line needs; this unit sits at the top of the range with a 3/4 in PT port. Choose the drain to suit access: automatic (as here) where the unit is hard to reach, manual where an operator drains it routinely, or the differential-pressure default. Pick 40 um for general protection or the 5 um element fitted here where finer cleanliness matters. Gauge scale (MPa, psi or bar), thread (PT standard, with G and NPT as order options), bracket and low-pressure versus standard regulator type are all decodable choices.
Because flow is published as curves and not as a single rating, we cannot quote one number here. Send us your application details and we will confirm sizing and the regulator adjustment range for this low-pressure type from 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 there is no one number we can honestly quote. Tell us your inlet pressure and demand and we will confirm the flow curve and sizing from the datasheet on request.
The W in the code selects the fine 5 um filtration grade instead of the 40 um standard, for applications that need cleaner air. The A selects an automatic drain, which expels collected condensate on its own - useful where the unit is mounted in a position that is awkward to drain by hand.
