The AirTAC GFR60020AJNT AirTAC Filter Regulator NPT3/4 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 GFR60020AJNT is a GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This size 600 unit has a 3/4 in NPT port, an automatic drain that clears collected condensate without manual attention, a 40 um standard filter element, and an aluminium alloy bowl. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and maximum inlet pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C (non-freezing). No pressure gauge is fitted on this variant and no mounting bracket is included.
This is a genuine AirTAC part. The GFR line is available in sizes 200, 300, 400 and 600, with port sizes from 1/8 to 1 in, PT as the standard thread and G or NPT as order options, automatic, manual or differential-pressure drains, and an optional 5 um element (code W). Rated flow is published as curves rather than a single figure, so ask us to confirm sizing 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. 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". |
| 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. |
| 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. |
| (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.

Feeding filtered, regulated air to the clutch-and-brake circuit of a stamping press, where steady downstream pressure keeps stroke timing consistent.
Conditioning shop air for tool-change cylinders and clamping fixtures on a machining centre, with the automatic drain keeping condensate out of the valves.
Supplying regulated air to diverters and stopper cylinders on a bottling or carton line, protected from water and scale by the 40 um element.
Size 600 with a 3/4 in NPT port suits lines with higher air demand; step down to 200, 300 or 400 if your flow and porting allow. Choose the drain to match access: automatic (this unit) for unattended duty, manual where someone checks the bowl, or differential-pressure as the family default. The 40 um element is standard; specify code W for 5 um where finer filtration is needed. Gauge and scale, PT vs G/NPT thread, and bracket options are further decodable choices on the family. 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 flow for the GFR series as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and datasheet figures for this 3/4 in unit on request.
No gauge is fitted - the code N variant omits it, and gauge options can be specified on other variants of the family. This unit has an automatic drain that discharges collected condensate by itself; manual and differential-pressure drains are available on the GFR series.
