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 manual drain and regulates 0.05 - 0.9 MPa (7 - 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 is a filter regulator: one body that removes water and particulate from compressed air and holds the downstream pressure steady. This GFR600-20T is the size 600 unit with 3/4 in NPT threads, a 5 um filter element, manual drain and a built-in reverse (check) valve. No gauge is fitted and no mounting bracket is supplied, so plan for a separate gauge and bracket if you need them.
It is a genuine AirTAC part. Size 600 is the largest G-series filter regulator, with an aluminium alloy bowl, a maximum inlet pressure of 1.0 MPa (145 psi) and a working temperature of -5 to 70 C (non-freezing). With the manual drain, the regulated outlet can be set anywhere from 0.05 to 0.9 MPa (7-130 psi). AirTAC publishes flow 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. Standard type, regulating 0.05 - 0.9 MPa (7 - 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". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 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.

Mounted at the machine's air drop, it strips water and 5 um particles and holds a steady regulated pressure to clamps and tool changers, while the built-in check valve holds the downstream setting if the upstream supply dips.
A 5 um element gives finishing air a cleaner supply ahead of point-of-use filtration, and the regulator lets the booth operator set gun pressure by hand; the manual drain is bled as part of the shift-start routine.
Feeding carton sealers and case erectors, the unit regulates pressure to the cylinders, and the check valve keeps the downstream circuit charged through brief compressor unload cycles.
Size 600 with 3/4 in ports is the largest step in the G series, so start there when line flow demand is at the top of the range; smaller 200/300/400 bodies with 1/8 to 1/2 in ports cover lighter duty. Thread is NPT on this unit, with G (BSPP) and PT as the other catalogue options, so match the thread to your fittings rather than adapting down. The 5 um element (code W) suits points of use that need cleaner air than the standard 40 um grade, and the manual drain (code M) needs an operator to bleed the bowl, unlike the automatic or differential-pressure drain options. Note that no gauge is fitted (code N) and no mounting bracket is included (code J). Because AirTAC publishes flow as curves rather than a single rating, ask us to confirm sizing against your required flow and pressure before ordering.
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 GFR600 as curves rather than a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm sizing against the datasheet on request.
Code M specifies a manual drain that an operator opens by hand to release collected water, and code W specifies the optional 5 um element instead of the standard 40 um grade. Both are factory build choices on this exact model; if you prefer automatic or differential-pressure draining, or the standard 40 um grade, those are separate order codes in the same series.
