The AirTAC GFR600-20 AirTAC Filter Regulator G3/4 Auto Drain 40 um 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 GFR600-20 is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit carries a G3/4 (BSPP) port, a 40 um standard filter element, an automatic drain that expels collected condensate without manual attention, and a fitted reverse/check valve that holds downstream settings when upstream pressure is lost. The aluminium alloy bowl suits this largest frame, and the round external gauge reads in psi. No mounting bracket is included with this configuration.
This is a genuine AirTAC part in the GFR600 series, the largest of the G-series filter regulator frames (sizes 200, 300, 400 and 600). Other options in the range include manual or differential-pressure drains, a 5 um element (code W), square embedded gauges, and MPa or bar scales. Flow is published as curves rather than a single rated figure, so we confirm the datasheet figures for your application on request.

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. |
| (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. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) 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.

Installed at the drop from a large plant air header to condition the supply feeding a production hall, cleaning the air and holding a set downstream pressure for the whole cell.
Mounted ahead of the air distribution on a packaging or conveyor line, delivering filtered, regulated air to the cylinders and actuators that drive the transport and wrapping stations.
Fitted at a maintenance or assembly station serving high-demand pneumatic tools, where the 3/4 in port, automatic drain and check valve keep the supply clean, set and held through the shift.
Choose the size and port step against the air demand of the circuit: size 600 with a G3/4 port is the largest GFR frame, so step down to GFR300 or GFR400 if the line is smaller. Pick the drain to match site practice: automatic (this unit) drains itself, manual needs operator attention, and the default differential-pressure drain works off the pressure drop across the element. The 40 um element is standard; order the W variant if the application needs 5 um filtration. Gauge scale (psi on this unit, or MPa/bar) and thread form (G as fitted here, with PT standard and NPT orderable) are selected at ordering, as is the bracket option.
Because flow is published as curves and not a single rating, 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR600 series as curves rather than a single rated figure, so we do not quote a number. Send us your application details and we will confirm the relevant flow and datasheet figures on request before you order.
The A in the code GFR60020AJC2GK specifies an automatic drain, which expels collected condensate from the aluminium bowl without operator attention. The range also offers manual drain (code M) and the differential-pressure drain (blank) as alternatives, and the 5 um element (code W) can be chosen instead of the standard 40 um.
