The AirTAC GFR60020ALC3WTK AirTAC Filter Regulator 3/4 in NPT 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 GFR60020ALC3WTK is an AirTAC GFR-series filter regulator: water-and-particulate filtration and pressure regulation combined in one body. This size-600 unit carries a 3/4 in NPT port, a 5 um filter element (code W), an automatic drain and an aluminium alloy bowl. The regulator is the low-pressure type, a round gauge scaled in bar is fitted, and a reverse/check valve is built in. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and can be ordered with manual or differential-pressure drains, the 40 um standard element, square or round gauges in MPa, psi or bar scales, G, NPT or PT threads, and with or without a bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.
| 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)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (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. |
| 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.

Feeding spray guns and air-assisted applicators on a paint line, where the 5 um element and low-pressure regulation keep moisture, particles and pressure swings out of the finishing air.
Filtering and regulating the air that drives stoppers, pushers and gripper cylinders along a packaging conveyor, with the automatic drain clearing condensate through long shifts.
Conditioning a compressed-air drop serving bench instruments and pneumatic test rigs, where the bar-scaled gauge gives a clear local setpoint and the check valve holds the line against backflow.
The real choices in this family are the size and port step, the drain type, the filter grade, the gauge and its scale, the thread and the bracket. Step up from size 200 through 600 as your line needs a larger port and more flow; this unit sits at the 3/4 in NPT size-600 level. The 5 um element (W) suits air feeding sensitive components, while the 40 um standard element covers general shop air. An automatic drain, fitted here, empties the bowl without attention; manual and differential-pressure drains are the alternatives. Gauges come as an embedded square gauge or an external round gauge in MPa, psi or bar - this unit has a round, bar-scaled gauge. Thread is PT as standard with G and NPT as order options, and a bracket is included. Flow is published as curves, not a single rating, so send us your flow and pressure requirements and we will confirm sizing against the datasheet before you order.
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 rather than a single rated figure, so we do not quote a number here. Tell us your required flow and working pressure and we will confirm the sizing from the datasheet on request.
The L in the code marks the low-pressure regulator variant, intended for circuits set below the standard type's range. The exact adjustment range for this variant is not published on our sheet, so ask us to confirm it against the datasheet before ordering. Everything else decodes normally: 3/4 in NPT port, 5 um element, automatic drain, aluminium bowl and a bar-scaled round gauge.
