The AirTAC GFR60020ALC3T AirTAC Filter Regulator NPT3/4, 3/4 in 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 GFR60020ALC3T is a GFR-series filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This size-600 unit has 3/4 in NPT ports, an automatic drain that expels collected condensate without manual attention, and the standard 40 um filter element. It is the low-pressure regulator type and includes an external round gauge scaled in bar; the aluminium alloy bowl suits this larger frame. 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, and options including manual or differential-pressure drains, a 5 um element (code W), square embedded or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm 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.

| C | Gauge shape: Round. C is round, F is square. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |

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.

Regulating filtered supply air to hot-melt glue pumps or low-pressure coating heads on a packaging line, where the 40 um element keeps scale and pipe debris out of metering valves and the automatic drain handles condensate unattended.
Feeding filtered, regulated air to clamp cylinders on a CNC fixture, holding the set working pressure through the cycle while the automatic drain keeps moisture out of the valve stack.
Supplying air knives that clean film or paper web on a converting line, where the filter protects nozzle orifices from particulate and the regulator sets the line's working pressure.
Pick the size step (200/300/400/600) and port against your line's air demand - this code is the 600 size with 3/4 in NPT ports for larger circuits. Drain choices are differential-pressure (default), automatic (this code, A) or manual (M); automatic suits unattended installations. The element here is the standard 40 um; specify W for 5 um where finer filtration is needed. This is the low-pressure regulator type, and the C3 suffix fits an external round gauge with a bar scale - the embedded square gauge and MPa or psi scales are the alternatives. Threads come as PT (standard), G or NPT; order the variant your piping uses, and a bracket is included for mounting. Flow is published as curves, not a single rating, so ask us to confirm sizing 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 GFR flow as curves rather than a single rated figure, so we do not quote one number. Send us your line pressure and air demand and we will confirm the flow from the datasheet for this size-600, 3/4 in unit on request.
The code decodes as: 600 size with 3/4 in ports, T for NPT threads, A for the automatic drain, L for the low-pressure regulator type, and C3 for an external round gauge scaled in bar. The embedded square gauge is standard, and MPa or psi scales can be ordered instead.
