The AirTAC GFR60020ALC2WT AirTAC Filter Regulator 3/4 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 AirTAC GFR60020ALC2WT is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built with a 3/4 in NPT port, a fine 5 um filtering element (code W), an automatic drain that expels collected condensate without manual attention, and the low-pressure regulator type. It carries a round pressure gauge reading in psi, and the aluminium alloy bowl suits the larger size-600 flow path. No reverse/check valve is fitted, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600, with port options from 1/8 to 1 inch, PT as the standard thread and G or NPT as order options, a choice of 40 um standard or 5 um fine filtration, differential-pressure, automatic or manual drains, standard or low-pressure regulation, and square or round gauges in MPa, psi or bar scales. Flow is published as curves rather than a single rating, so ask us to confirm the figures for your application 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. 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). |
| 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. |
| (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.

On a packaging line where sealing or forming stations run at reduced pressure, this filter regulator cleans the shop air with its 5 um element and holds the lowered setting, with the automatic drain keeping condensate off the station.
Pneumatically actuated butterfly and ball valves need clean, steady, reduced-pressure air to their positioners and actuators. This 3/4 in unit conditions the branch feeding the valve cluster, with the psi gauge giving operators a local reading.
Air cylinders that push bottles between conveyor lanes run continuously and are sensitive to water carryover. This filter regulator conditions the branch serving the divertors, and the automatic drain suits a line that runs unattended between shifts.
Start with the port step: size 600 with a 3/4 in NPT port is the largest GFR frame, chosen when the line diameter and air demand point to the top of the range. The 5 um element (code W) is the finer choice over the 40 um standard where downstream valves or instruments need cleaner air. The automatic drain suits unattended installations; manual and differential-pressure drains are the alternatives on other configurations. The round psi gauge is fitted here; square embedded gauges and MPa or bar scales are options. NPT is an order option against the PT standard, and G (BSPP) is also available. A bracket is included on this code. Because flow is published as curves rather than 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR flow as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure, downstream setting and air demand, and we will confirm the sizing from the datasheet on request.
The L code selects the low-pressure regulator variant, intended for reduced downstream settings rather than the standard range. The exact adjustment range for this variant is not published in our sheet, so ask us to confirm it on request. Everything else on this code decodes as: 3/4 in NPT port, 5 um element, automatic drain, round psi gauge, aluminium bowl and included bracket.
