The AirTAC GFR60020ALNWT 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 GFR60020ALNWT is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size 600 unit is threaded NPT3/4 (3/4 in), carries a 5 um filter element (code W) and drains collected condensate automatically (code A). The regulator is the low-pressure type, and no gauge is fitted (code N). The 600-size bowl is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 to 1 in, and options include manual or differential-pressure drains, the 40 um standard element, fitted gauges, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet numbers 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. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 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. |
| (blank) | No reverse-flow valve (the default). |
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.

Filters and regulates supply air to low-pressure clamping actuators on machining fixtures. The 5 um element protects valve and cylinder seals, and the automatic drain clears condensate from long header runs without operator attention.
Conditions air feeding gate and diverter cylinders on carton and case lines. Filtered, regulated low-pressure air keeps gate timing consistent, while the automatic drain stops accumulated water reaching the valves between shifts.
Serves low-pressure jets and threading air on spinning frames in dusty mill environments. The 5 um element limits carryover of particles, and the included bracket allows clean panel mounting beside the machine.
Size 600 with a 3/4 in port suits circuits with substantial air demand; step down to 200, 300 or 400 for smaller lines, sizing the unit against required flow. This unit carries the 5 um element (code W); the 40 um standard grade is available where finer filtration is not required. The automatic drain ejects condensate without manual attention, while manual and differential-pressure drains are the alternatives. The regulator here is the low-pressure type - confirm your setpoint with us before ordering. No gauge is fitted; gauges with MPa, psi or bar scales can be ordered. NPT is specified on this code; PT and G threads are catalogue options, and a bracket is included. Flow is published as curves, not a single rating, so let us confirm sizing against your application before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back 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 no rated flow number can be quoted here. Send us your air demand and operating pressure and we will confirm the sizing from the datasheet curves on request.
The W in the code specifies the 5 um element instead of the 40 um standard grade, and the A specifies an automatic drain instead of the default differential-pressure type. Manual-drain and 40 um versions are available if you prefer those choices.
