The AirTAC GFR60020ALC2WTK 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 GFR60020ALC2WTK is an AirTAC GFR600 filter regulator: water and particulate filtration plus pressure regulation in a single body. This size-600 unit is fitted with a 3/4 in NPT port, a 5 um filter element (the fine grade, in place of the standard 40 um), an automatic drain that expels collected condensate without manual attention, and a reverse/check valve. It is the low-pressure regulator type, and the fitted round gauge reads in psi. The aluminium alloy bowl suits this largest frame, and a mounting bracket is included.
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, drain, filter-grade, gauge and thread options to order. Published flow data appears as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. 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. |
| 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.

Feeding filtered, regulated air to case packers and wrapping machines on a packaging line, where the 5 um element protects sealing and actuation circuits and the automatic drain keeps condensate off the machine floor.
Conditioning the air supply to a pneumatic press or forming station that runs at low regulated pressure, with the round psi gauge giving operators a clear local setpoint reading.
Serving as the point-of-use filter regulator on a 3/4 in air drop feeding an assembly cell, with the reverse/check valve holding downstream conditions and the automatic drain suiting an unattended drop location.
Choose the GFR600 frame when your line needs the largest port step in the family: this unit carries a 3/4 in NPT thread (PT is the standard thread; G and NPT are order options, and this code is the NPT version). The 5 um element (code W) suits downstream equipment sensitive to finer particulate; the standard grade is 40 um. The automatic drain (code A) suits unattended or hard-to-reach installations; manual and differential-pressure drains are the alternatives in the family. This is the low-pressure regulator type, so confirm its adjustment range against your setpoint with us before ordering. The fitted round gauge reads in psi; embedded square gauges with MPa, psi or bar scales are the standard alternative. A mounting bracket is included.
Because flow for this family is published as curves rather than a single rating, ask us to confirm sizing against your required flow 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 family as curves, not as a single rated figure, so we do not quote a number here. Tell us your required flow and line conditions and we will confirm the sizing from the datasheet on request before you order.
In the code GFR60020ALC2WTK, the A position selects the automatic drain, which expels collected condensate on its own instead of waiting for a manual or differential-pressure drain cycle, and the W position selects the 5 um filter element instead of the standard 40 um grade. Both are catalogue options; other drain types and grades are available in the family.
