The AirTAC GFR60020ALF3WTK AirTAC Filter Regulator 3/4in NPT 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 GFR60020ALF3WTK is an AirTAC GFR600 filter regulator: it removes water and particulate from compressed air and holds a set downstream pressure in a single body. This configuration is built for 3/4 in NPT ports, filters to 5 um, and drains condensate automatically, so the bowl does not need manual attention. It is the low-pressure regulator type and carries a reverse/check valve. The embedded square gauge reads in bar (an external round gauge is available as an option), the aluminium alloy bowl suits the 600 size, and the 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 in to 1 in, and options for drain type, 40 um or 5 um filtration, gauge scale, G or NPT thread, and bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm flow and 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

|---|---|
| 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)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. 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. |
| 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.

On assembly fixtures with air-operated clamps, this unit filters the supply to 5 um and holds a low regulated set pressure, with the check valve holding the circuit if upstream air is interrupted.
A spray booth air drop uses this unit to strip water and particulate ahead of guns and to set a stable, lower working pressure, while the automatic drain clears condensate through the shift.
Diverters, pushers and stop cylinders on a packaging conveyor run on air regulated downstream of this unit, with the 3/4 in NPT connection feeding a main branch header.
Pick the size by port and required flow: 600 is the largest step in the family, here with 3/4 in NPT ports. The A code selects the automatic drain; manual and differential-pressure drains are the alternatives. The W code selects 5 um filtration instead of the 40 um standard. The F3 code gives the square gauge with a bar scale (MPa and psi scales are options), and the L code makes this the low-pressure regulator type - confirm its exact set range with us before ordering. The thread here is NPT; PT is the standard and G is orderable as a specification option. The mounting bracket is included. Because flow is published as curves, 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 this family as curves, not as a single rated figure, so no flow number is stated here. Tell us your line pressure, set pressure and expected air demand, and we will confirm the flow from the datasheet on request.
L marks the low-pressure regulator type, as opposed to the standard type. The exact adjustment range for the low-pressure type is not published in the material we hold, so confirm the set range with us on request. The rest of the code decodes as: 600 size, 3/4 in NPT port, automatic drain, square bar gauge, 5 um filter grade, and a fitted reverse/check valve.
