The AirTAC GFR60020AJF2WTK AirTAC Filter Regulator NPT3/4 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 GFR60020AJF2WTK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 600-size unit is specified with a 3/4 in NPT port, 5 um filtration (the finer W grade, versus the standard 40 um element), an automatic drain that discharges collected condensate without manual attention, and an embedded square gauge reading in psi. A reverse/check valve is fitted, and the unit is supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). The regulation range is 0.15-0.9 MPa (20-130 psi). Because this is the 600 size, the bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of ports, thread types (PT standard, with G and NPT as order options), drain types, filter grades, gauge styles and scales, and bracket options. Flow is published as curves rather than a single rated figure, so we confirm flow and datasheet figures 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). |
| F | Gauge shape: Square. 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. |
| 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 take-off from a factory compressed-air main to remove water and pipe scale and hold a steady regulated pressure for downstream tool circuits on a 3/4 in line.
Feeding filtered, regulated air to the clamping and tool-change circuits of a CNC machining centre, where the 5 um element helps protect sensitive valves from fine particulate.
Supplying clean, regulated air to cylinders and actuators on a packaging or palletising conveyor line, with the automatic drain handling condensate during continuous shifts.
Choose the 600 size with its 3/4 in NPT port when your line flow and piping call for the largest step in the GFR range; smaller sizes (200/300/400) step down in port and flow. This unit's automatic drain suits unattended duty; a manual-drain variant is available where you prefer periodic draining. The 5 um W-grade element is the right choice when downstream equipment is sensitive to finer particles; the standard grade is 40 um. The embedded square gauge here reads in psi; MPa and bar scales and an external round gauge are alternatives. Thread is NPT on this unit - PT is the standard and G/NPT are order options - and the bracket is omitted (J code). Flow for this family 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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a number here. Contact us and we will confirm the flow curve and sizing against your application from the datasheet before you order.
The A in the code sets the automatic drain, which discharges collected condensate without manual attention - useful on lines that run unattended. The W sets the 5 um filter grade, one step finer than the 40 um standard element, for applications where finer particulate removal is wanted.
