The AirTAC GFR600-20T AirTAC Filter Regulator NPT 3/4 in, 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 GFR600-20T is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit is specified with a 3/4 in NPT port, a 5 um filter element (the finer of the two catalogue grades), an automatic drain that expels collected condensate without manual attention, and a round pressure gauge reading in psi. A reverse/check valve is fitted, and the unit is supplied without a mounting bracket. The maximum working (inlet) pressure is 1.0 MPa (145 psi) and the regulator adjustment range is 0.15-0.9 MPa (20-130 psi). At size 600 the bowl is aluminium alloy, and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to 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. 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.

|---|---|
| 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)). |
| (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. |
| 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. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Feeding clean, regulated air to the tool-change and clamping circuits of a machining center, where the 5 um element protects precision valves from particulate and the automatic drain keeps condensate out of the supply.
Supplying regulated air to carton-forming and sealing cylinders on a packaging line, with the reverse/check valve holding the downstream circuit and the psi gauge letting operators verify set pressure at a glance.
Conditioning air at the drop feeding a robotic assembly cell: filtration plus regulation in one body saves panel space at the 3/4 in main feed, and the automatic drain suits an unattended cell.
Size 600 with a 3/4 in NPT port is the largest step in the GFR range, so start by matching the port and size step against the flow your line needs - we can confirm the published flow curves against your demand before you order. This unit is already configured with the finer 5 um element, the automatic drain, a psi round gauge and a reverse/check valve, so the remaining decodable choices are thread style: NPT is fitted here, while PT (standard) and G are catalogue options to order. Note that no mounting bracket is included with this code.
If your application can tolerate coarser 40 um filtration, or you prefer a manual or differential-pressure drain, those variants exist in the same family - tell us the duty and we will confirm the right configuration.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow 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 number here. Send us your flow demand and line pressure and we will confirm the datasheet curve figures for this 3/4 in size 600 unit before you order.
The code suffixes set both: W selects the finer 5 um element instead of the 40 um standard, and A selects the automatic drain, which discharges collected condensate by itself instead of relying on the differential-pressure drain of the default configuration. A 40 um or manual-drain variant can be ordered if your application prefers it.
