The AirTAC GFR60020ALF2WT 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 GFR60020ALF2WT is an AirTAC GFR600 filter regulator: a single body that removes water and particulate from compressed air and holds downstream pressure steady. This configuration is built around 3/4 in NPT ports, a 5 um filter element, an automatic drain that ejects collected condensate without operator attention, and the low-pressure regulator type for circuits that run below standard line pressure. The 600-size bowl is aluminium alloy, a square gauge scaled in psi is fitted so the regulated setting can be read at a glance, and the mounting bracket is included. 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 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, PT as the standard thread and G (BSPP) or NPT as order options, manual and differential-pressure drains as alternatives to the automatic drain fitted here, a 40 um standard element with the 5 um grade optional, and gauge or no-gauge variants. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures 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.

| F | Gauge shape: Square. 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. |

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.

Filtered, low-pressure regulated air to powder spray guns, where the 5 um element helps keep moisture and fine particles out of the finish and the automatic drain copes with condensate through continuous shifts.
Supplying filtered, regulated air to the cylinders and grippers on a packaging conveyor, with the 3/4 in port feeding a main drop and the psi gauge letting line staff verify the setting during changeover.
Providing stable, low-pressure regulated air on a workshop test bench where components are cyclically proof-tested, with the aluminium bowl and automatic drain handling condensate from repeated cycling.
The choices that matter on this family: step up or down in size (200/300/400/600) to match the port and flow path your line needs - this unit sits at the top of the range with 3/4 in NPT ports. The drain fitted here is automatic, which suits unattended or continuous duty; manual (M) and differential-pressure (blank) drains are orderable alternatives. The element is the 5 um option (code W); the 40 um standard element is the choice where only coarse protection is required. The embedded square gauge is scaled in psi, with MPa or bar scales and an external round gauge as alternatives, and the low-pressure (L) regulator type is what separates this code from the standard version. Thread is NPT here; PT is the standard and G (BSPP) is an order option - all are specifications to order, not delivery commitments.
Flow for the GFR series is published as curves, not a single rated figure, so send us your application details and we will confirm sizing against the datasheet before you order. A mounting bracket is included with this code; a no-bracket version (code J) is available if panel or manifold mounting is planned.
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 rather than a single rated figure, so we do not quote a number here. Send us your line pressure, downstream demand and duty profile, and we will confirm the sizing from the datasheet on request before you order.
The A in the code specifies an automatic drain, which ejects collected condensate from the aluminium bowl without operator attention - useful on unattended or continuous-duty installations. Manual (M) and differential-pressure (blank) drains are orderable alternatives on the GFR600 series, as is the 40 um standard element if 5 um filtration is finer than the application needs.
