The AirTAC GFR60020ALF2WTK AirTAC Filter Regulator NPT3/4 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 GFR60020ALF2WTK is a size-600 filter regulator: it removes water and particulate from compressed air and reduces pressure to the working level in a single body. This configuration is built for a 3/4 in NPT port, carries the fine 5 um filter element (code W), and drains condensate automatically, so the bowl empties itself during operation without manual attention. It is the low-pressure type for circuits that run at reduced settings, and the fitted square gauge reads in psi so operators can see and set the downstream pressure at a glance. A reverse/check valve is fitted, and the size-600 bowl is aluminium alloy with a mounting bracket included.
This is a genuine AirTAC part in the largest of the G-series filter-regulator sizes (200, 300, 400 and 600), each available with a choice of drain type, filter grade, gauge scale and thread. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm the 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.

|---|---|
| 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). |
| 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. |
| 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.

Feeds filtered, reduced-pressure air to spray guns in a finishing booth, with the 5 um element helping keep water and grit out of the finish and the automatic drain clearing condensate between shifts.
Sits at the drop point of a bottling-hall air ring, filtering the supply and holding a steady reduced pressure to the conveyor's pneumatic cylinders and stop-gate actuators.
Conditions the house-air feed to a lab bench skid: particulate and moisture removed at 5 um, downstream pressure set from the psi gauge, and condensate handled automatically without operator attention.
Step up through the G-series sizes (200, 300, 400, 600) as your port and air demand grow; this unit is the 600 size with a 3/4 in NPT port, the largest step in the range. Choose the drain to match maintenance reality: automatic (this unit) empties the bowl on its own, manual suits attended installations, and differential-pressure drain is the catalogue default. Pick the 5 um element (code W, as here) when downstream equipment needs finer filtration than the 40 um standard. The embedded square gauge is standard and this one reads psi; external round gauges and MPa or bar scales are options. Thread is NPT here, with G (BSPP) and PT available to order, and a mounting bracket is included. Because flow is published as curves rather than a single rated figure, send us your application details 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, not as a single rated number, so we do not quote a figure here. Send us your line pressure and air demand and we will confirm the datasheet flow curve and sizing for this 3/4 in unit on request.
The W code fits the fine 5 um element instead of the 40 um standard, which suits downstream equipment that is sensitive to water and fine particulate. The A code selects the automatic drain, so condensate is expelled from the aluminium bowl during operation rather than waiting for someone to bleed it manually.
