The AirTAC GFR60020AJC3WT AirTAC Filter Regulator NPT3/4 5um 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 GFR60020AJC3WT is a size-600 filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body. This configuration carries a 3/4 in NPT port, a fine 5 um filter element (the W grade, against the 40 um standard), an automatic drain that expels collected condensate without manual attention, and an external round pressure gauge scaled in bar. The size-600 bowl is aluminium alloy, the regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, and no mounting bracket or reverse/check valve is fitted.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and can be ordered with manual or differential-pressure drains, a 40 um standard element, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, 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.
| 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. |
| 3 | Gauge scale: bar. 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. |
| (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.

Filtering and regulating the plant air feeding spray guns and air-assisted applicators, with the 5 um element helping protect finish quality and the automatic drain handling condensate on a continuously running line.
Supplying clean, regulated air to the pneumatic cylinders that press and seal cartons on a packaging conveyor, with the bar-scaled gauge giving operators a local setpoint reference at the machine.
Conditioning the air feeding directional control valves on a bottling line fill-and-capper section, combining water and particulate removal with a stable regulated pressure in one 3/4 in body.
Size up by port and required flow: the GFR600 step with its 3/4 in port suits the larger end of the range, and stepping to 300 or 400 reduces both port and flow capacity. Choose the drain to match the installation: automatic (this unit) suits unattended duty, manual suits periodic checks, and the differential-pressure default drains on load. Pick the filter grade for the duty: 40 um is the standard element, 5 um (this unit's W code) for finer protection of downstream components. Select the gauge scale (MPa, psi or bar) and thread (PT standard, G or NPT to order); brackets are optional on this 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. Tell us your application and we will confirm the flow and datasheet figures for this 3/4 in, size-600 unit on request before you order.
The A in the code gives an automatic drain, which expels collected condensate from the aluminium bowl without an operator opening it. The alternatives are manual drain (you drain it yourself on a schedule) and the differential-pressure default (drains on load); automatic suits installations that run unattended.
