The AirTAC GFR60020AC2WTK AirTAC Filter Regulator NPT3/4, 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 GFR600-20 (full code GFR60020AC2WTK) is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This size 600 unit is threaded 3/4 in NPT and carries the 5 um filter element (code W) plus an automatic drain that expels collected condensate without manual attention. The round pressure gauge reads in psi, the aluminium alloy bowl suits the larger 600 frame, and the built-in standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi). Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), a reverse/check valve is fitted, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options include manual or differential-pressure drains, a 40 um standard element, an embedded square gauge or an external round gauge in MPa, psi or bar scales, G (BSPP) or NPT threads, and low-pressure or check-valve variants. Flow is published as curves rather than a single rated figure, so ask us to confirm flow and datasheet details 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.

| 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. |

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.

Filtered, regulated air for the tool changer, clamps and actuator circuits on a CNC machining centre, with the 5 um element guarding against fine particle carryover into precision components.
Steady regulated pressure for stopper cylinders and diverter gates on a bottling or packaging conveyor, with the automatic drain clearing condensate through long production shifts.
Clean, stable air to spray guns in an automotive paint booth, where the 5 um element and steady downstream regulation help protect finish quality from water and particulate.
Choose the size by the port and air demand of your line: sizes 200 to 600 step up from 1/8 to 1 inch, and this 600 unit lands at 3/4 in NPT. Pick the drain: automatic (this unit) for unattended condensate removal, manual for periodic draining, or the differential-pressure default. Pick the element: 40 um standard or 5 um (code W) for finer protection - this unit carries the 5 um element. Gauges come as the embedded square type or an external round gauge, scaled in MPa, psi or bar; this unit has a round psi gauge. Thread is PT as standard with G (BSPP) and NPT as order options - this unit is NPT - and a mounting bracket is included. 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR600 flow as curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure and air demand and we will confirm the flow from the datasheet for your application before you order.
This configuration carries code A, the automatic drain, which expels collected condensate on its own - useful where the unit is not checked daily. The GFR family also offers a manual drain and a differential-pressure drain as the default; with the automatic drain the regulator range is 0.15-0.9 MPa (20-130 psi).
