The AirTAC GFR60020ALC2WGK AirTAC Filter Regulator G3/4, 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 GFR60020ALC2WGK is an AirTAC GFR600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built around a G3/4 port, a 5 um filter element (code W), an automatic drain that ejects collected condensate without manual attention, and the low-pressure regulator type. It includes a round psi gauge, a reverse/check valve, a mounting bracket, and the size-600 bowl in aluminium alloy. Operating temperature is -5 to 70 C (non-freezing), with a maximum inlet pressure of 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GFR family covers sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, drain choices of differential-pressure, automatic or manual, 40 um standard or 5 um filtration, gauge and thread options, and standard or low-pressure regulation. Rated flow is published as curves rather than a single figure, so ask us to confirm the datasheet and sizing 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. |
| (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. |
| G | G (BSPP) 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.

Feeding a pneumatic press or clamping fixture on a production line: the 5 um element protects directional valves and cylinders from water and particulate while the regulator holds a steady low-pressure setting.
Supplying air to conveyor stopper cylinders and gating actuators on a packaging line, where the automatic drain keeps condensate out of the circuit during continuous shifts.
Point-of-use preparation at a CNC machine tool or assembly cell, combining filtration and regulation in one body ahead of solenoid valves and air motors.
Choose the size by port and flow: sizes 200 through 600 step up from 1/8 to 1 inch, and size 600 here gives a 3/4-inch G thread. Drain type is a real choice: automatic (this unit) needs no manual draining, manual suits supervised installations, and differential-pressure is the default. Filter grade is 40 um standard or 5 um (code W) for finer protection of downstream components. Gauge options are an embedded square gauge or an external round gauge, scaled in MPa, psi or bar - this unit carries a round psi gauge. Thread is PT as standard with G and NPT as order options, and a mounting bracket is included unless code J is specified. 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
Flow for the GFR600 series is published as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the datasheet figures and check the sizing for you before you order.
The L in the code marks the low-pressure regulator type. The exact adjustment range for this type is not published in the sheet we work from, so we confirm it on request; the standard type's published range does not apply here. The unit still accepts up to 1.0 MPa (145 psi) inlet, operates from -5 to 70 C, and carries a 5 um element, automatic drain, round psi gauge and reverse/check valve.
