The AirTAC GFR60020ALF2WG AirTAC Filter Regulator G3/4 5 um Auto Drain 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 GFR60020ALF2WG is an AirTAC GFR600 filter regulator: a single body that removes water and particulate from compressed air and regulates downstream pressure. This 600-size unit is ported G3/4 and carries the W filter grade, a 5 um element for finer filtration than the 40 um standard. It is the low-pressure regulator type, fitted with an automatic drain that expels collected condensate without manual intervention, an embedded square gauge reading in psi, and an aluminium alloy bowl. 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 sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and is available with manual, automatic or differential-pressure drains, 40 um or 5 um filtration, standard or low-pressure regulation, square or round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow for this series is published 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.

|---|---|
| 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. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |

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 spray guns on a finishing line with filtered, regulated low-pressure air: the 5 um element and automatic drain keep water and particulate out of the finish work while the psi gauge gives operators a local setpoint reading.
Regulating the supply to pneumatic actuators on a packaging conveyor. The automatic drain handles condensate on a line that is not checked every shift, and the G3/4 port suits the header feeding several machines.
Supplying quarter-turn actuators in a water treatment or process plant: the low-pressure regulator type sets the actuator supply pressure, the 5 um grade protects the actuator internals, and the aluminium alloy bowl suits the plant environment.
Size drives port and flow capacity: the GFR family steps through 200, 300, 400 and 600, and this unit sits at the top with a G3/4 port, so match the size to the air demand of the line rather than to the pipe alone. Drain choice matters: automatic (this unit) suits installations that are not checked daily, manual suits attended plants, and differential-pressure is the catalogue default. Filtration is 5 um here (code W) against the 40 um standard - choose 5 um where downstream equipment needs finer air. The gauge is the embedded square type reading psi; an external round gauge and MPa or bar scales are options. Thread is G (BSPP); PT is the standard thread and NPT is an order option, so confirm which your pipework needs. A mounting bracket is included.
Because AirTAC publishes flow only as curves and not as a single rated figure, we do not quote a flow number here. Send us your application's air demand 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR-series flow as curves rather than as a single rated figure, so we do not quote a number here. Tell us your line's air demand and we will confirm the flow curve and sizing for the GFR60020ALF2WG from the datasheet on request.
This unit's code carries A for automatic drain, meaning condensate collected in the bowl is expelled without an operator opening a valve - useful where the unit is not checked daily. Manual drain suits attended plants, and differential-pressure is the catalogue default; all three are orderable in the GFR family.
