The AirTAC GFR60020ALJF2WGK AirTAC Filter Regulator G3/4 Low-Pressure 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 GFR600 series combines water-and-particulate filtration with pressure regulation in a single body, and this configuration, GFR60020ALJF2WGK, is the size 600 unit with a G3/4 (BSPP) port. It carries a 5 um filter element (code W, versus the 40 um standard), an automatic drain that bleeds collected condensate from the bowl without manual attention, and a low-pressure regulator type. The embedded square gauge is fitted and reads in psi, and a reverse/check valve is built in. The size 600 bowl is aluminium alloy, and the maximum working (inlet) pressure is 1.0 MPa (145 psi) with an operating temperature of -5 to 70 C, non-freezing. No mounting bracket is included (code J).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and options include drain type, filter grade, gauge style and scale, thread form and bracket choice. Because flow is published as curves rather than a single rated figure, we confirm the datasheet and flow figures for this exact model 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.
| 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. |
| J | Supplied without bracket. |
| (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. |
| 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 filtered, regulated air to a stamping or forming press station on a 3/4 inch ring main, where the 5 um element protects directional valves and cylinders from particulate carryover.
Conditioning supply air at the drop point of a cartoning or filling line, with the automatic drain handling condensate on a line that runs unattended across shifts.
Regulating supply to air tables, clamping fixtures or low-pressure actuators that operate below standard line pressure, with the built-in check valve holding the set circuit against backflow.
Start with size and port: the 600 size with a G3/4 port is the largest step in the GFR range, so match it to the pipe diameter and the air demand of the circuit downstream. Then set the drain: automatic (this unit) suits installations that are not visited daily, manual drain suits attended stations, and differential-pressure drain is the catalogue default. This unit carries the 5 um element (W) rather than the 40 um standard - choose 5 um where downstream equipment needs finer particulate removal. The low-pressure type (L) is intended for circuits regulated below the standard range; the exact adjustment range for the low-pressure type is not published in our sheet, so confirm it with us before ordering. The fitted square gauge reads in psi; MPa and bar scales and an external round gauge are alternatives. Thread is G (BSPP); PT is the standard thread form and NPT is available to order. No bracket is fitted (J); a bracket is optional on this family.
One honest note on sizing: flow for the GFR600 is published as curves, not a single rated number, so we do not quote a flow figure here. Ask us to confirm the curve data against your application 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 GFR600 as performance curves, not as a single rated figure, so we do not quote a flow number for this model. Tell us your application and we will confirm the curve data and sizing from the datasheet on request before you order.
This unit carries the L code, meaning it is the low-pressure regulator type rather than the standard type, intended for circuits regulated below the standard adjustment band. The exact adjustment range for the low-pressure type is not published in our sheet, so please confirm the range with us on request. The maximum working (inlet) pressure remains 1.0 MPa (145 psi).
