The AirTAC GFR600-20ALC2G AirTAC Filter Regulator G3/4 Low-Pressure is a genuine G-series filter regulator: water separation, 40 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 GFR600-20ALC2G is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a G3/4 (3/4 in) G-thread port, a 40 um standard filter element, an automatic drain that expels collected condensate without manual attention, and a fitted round gauge reading in psi. It is the low-pressure type, intended for circuits where regulated pressure sits below the standard regulator band; the exact adjustment range for the low-pressure type is not published in the catalogue and we confirm it on request. The aluminium alloy bowl reflects the size-600 construction, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and can be ordered with manual or differential-pressure drains, a 5 um (code W) element, square or round gauges in MPa, psi or bar scales, PT or NPT threads, and with or without a bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm flow and datasheet figures for your application before ordering.

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. |
| (blank) | Filtering grade 40 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.

Feeds and regulates air to a light-duty pneumatic press or clamping fixture that operates at reduced pressure, with the automatic drain keeping condensate out of the valve stack between shifts.
Mounted at the drop of a packaging or cartoning line, it filters water and debris from the plant air supply and holds a steady reduced pressure to the line's cylinder-driven sealing and forming stations.
Installed at the air inlet of textile or weaving machinery, it conditions the supply with 40 um filtration and low-pressure regulation, and the psi round gauge lets operators verify setting at a glance.
Choose the size-600 / G3/4 step when your line's flow demand calls for the largest GFR frame; smaller sizes 200-400 step down in port and flow capacity. Drain choice matters: the automatic drain here suits unattended or hard-to-reach installations, while manual and differential-pressure drains are orderable alternatives. The 40 um element is the standard grade; specify code W for the 5 um fine grade if downstream components need finer filtration. The fitted round gauge reads psi; square embedded gauges and MPa or bar scales are available. G thread is as coded here, with PT and NPT offered as order options, and the included bracket simplifies panel or wall mounting. Because flow is published as curves and the low-pressure type's adjustment range is not stated as a single figure, ask us to confirm sizing and the regulated range against your application 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 flow for the GFR series as curves, not as a single rated number, so we do not quote a figure here. Tell us your application and we will confirm the flow from the datasheet curves on request before you order.
The A in the code sets the automatic drain, which ejects collected condensate on its own instead of waiting for a manual or differential-pressure drain cycle, and C2 sets the optional external round gauge with a psi scale. The embedded square gauge remains the standard fitting, and MPa or bar scales are orderable alternatives.
