The AirTAC GFR600-20T AirTAC Filter Regulator 3/4 in NPT 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 differential-pressure 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 GFR600-20T is a size 600 filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has 3/4 in NPT ports, the standard 40 um filter element, a differential-pressure drain on the bowl, standard regulation over 0.15-0.9 MPa (20-130 psi), and a round MPa gauge fitted. The size 600 bowl is aluminium alloy, and maximum inlet pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port options from 1/8 to 1 inch, PT, G and NPT threads, automatic, manual or differential-pressure drains, a 5 um optional element (code W), and gauge or bracket choices. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard 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. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT 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.

Installed at the 3/4 in main air drop feeding a packaging line, it cleans water and scale out of the supply and holds a steady regulated pressure to the line's pneumatic valves and actuators.
Mounted ahead of the air cylinders and control valves on a conveyor or sorting system, it keeps grit and condensate out of the actuators while the regulator holds the setting the drive was set up for.
Fitted on the air inlet of a CNC machine tool or press auxiliary circuit, it delivers filtered air to clamps, tool changers and purge points at the fixed pressure the machine builder specifies.
Choose the size and port step against the air demand of the circuit: this unit is size 600 with 3/4 in NPT ports, the largest step in the GFR range. The drain here is differential-pressure, which bleeds the bowl automatically as pressure drops; automatic (code A) and manual (code M) drains are the other decodable choices. The standard element is 40 um, with a 5 um element available as code W when finer filtration is needed. Thread is NPT on this model; PT is the standard series thread and G is also an order option. A bracket can be added, and gauge scale can be specified as MPa, psi or bar. Flow for the GFR series is published as curves, not a single rating, so please 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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a rated flow number. Send us your application details and we will confirm the flow and sizing from the datasheet on request.
The differential-pressure drain on this unit bleeds collected condensate from the bowl automatically as the pressure across it changes, with no operator action. If you prefer a set-and-forget float action or a hands-on drain, automatic (code A) or manual (code M) versions can be ordered instead.
