The AirTAC GFR60020ALC2WG AirTAC Low-Pressure Filter Regulator G3/4 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 GFR60020ALC2WG is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and regulates the downstream pressure. This configuration is the 600 size with a G3/4 (BSPP) port, a 5 um filter element (code W), an automatic drain, the low-pressure regulator type, and a round pressure gauge reading in psi. The bowl at this size is aluminium alloy, maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and a mounting bracket is included.
This is a genuine AirTAC part. The GFR series is offered in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and with manual, automatic or differential-pressure drains, 40 um standard or 5 um elements, embedded square or external round gauges in MPa, psi or bar scales, and PT, G (BSPP) or NPT threads. Rated flow is published only as curves rather than a single figure, so ask us and we will confirm the datasheet figures 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.

|---|---|
| 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. |
| (blank) | Mounting bracket included. |
| (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. |
| G | G (BSPP) 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.

At a refinish shop's booth drop, the unit strips water and 5 um particulate from shop air and holds the low regulated pressure spray guns need, while the automatic drain clears condensate through the shift without anyone opening the bowl.
On a lab bench that cycles instruments and fixtures at low regulated pressure, the low-pressure regulator type and psi-reading round gauge let technicians set and read the supply directly, with the 5 um element protecting sensitive test gear.
In a treatment plant's actuated valve manifold, the unit filters the plant air supply and regulates it down to the low pressure the diaphragm actuators are specified for, with the automatic drain handling condensate in a room that is not visited daily.
Start with the size and port step - 200, 300, 400 or 600, from 1/8 to 1 inch - matched to the air demand of the line. Drain type is a real choice: automatic drains discharge condensate without attention, manual drains are emptied by hand, and the differential-pressure default drains on a pressure drop. Filter grade is 40 um standard or 5 um (this unit, code W) where finer protection is needed. Gauges are an embedded square gauge as standard with an external round gauge optional, in MPa, psi or bar scales; thread is PT as standard with G (BSPP) and NPT as order options, and a bracket is included unless code J is specified. Because rated flow is published as curves rather than a single number, send us your application 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 GFR flow as curves rather than a single rated figure, so we do not quote a number on the page. Tell us your line's air demand and working pressure and we will confirm the datasheet curve and the correct size before you order.
The GFR series offers manual, automatic and differential-pressure drains. The automatic drain (code A on this model) discharges collected condensate without anyone opening the bowl, which suits unattended plant rooms; a manual drain is emptied by hand and the differential-pressure default drains on a pressure drop.
