The AirTAC GFR60020ALJF2WG 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 AirTAC GFR60020ALJF2WG is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built for a G3/4 (3/4 in) G-thread port, carries a 5 um filter element for finer filtration than the 40 um standard, and drains condensate automatically, so the bowl does not depend on an operator or on a pressure drop to empty. The regulator is the low-pressure type, and the embedded square gauge reads in psi. Because it is a size-600 unit, the bowl is aluminium alloy. No mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and can be ordered with manual or differential-pressure draining, a 40 um or 5 um element, a square or external round gauge in MPa, psi or bar scales, a reverse/check valve, a mounting bracket, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application 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.

|---|---|
| 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. |
| (blank) | No reverse-flow valve (the default). |
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, regulated air to the heat-seal and clamp cylinders on a packaging machine, with the 5 um element protecting valve seats and the automatic drain clearing condensate through long shifts without operator attention.
Supplies the low-pressure air feed to air knives that blow moisture off bottles or parts moving down a conveyor, with the square psi gauge giving operators a direct local reading of the setting.
Mounted at the inlet of a machine's air-preparation panel, it filters and regulates the supply feeding clamps and grippers on an assembly fixture, with the G3/4 port matching the main drop leg into the panel.
Start with the port step: this unit is the size-600, G3/4 (3/4 in) frame, the largest in the GFR range - step down to 200/300/400 if your line runs smaller ports and lower air demand. Choose the drain to match how the unit will be tended: automatic (this code) empties the bowl without operator action, manual requires someone to open the drain, and the differential-pressure default drains on a set pressure drop. This code carries the 5 um element (code W) instead of the 40 um standard - pick 5 um where downstream equipment needs finer air. The square gauge here reads in psi; MPa and bar scales and an external round gauge are alternatives. Thread: PT is the standard on this family, while G (this code) and NPT are order options - specify the one that matches your piping. Brackets are optional; this code ships without one. Flow for this family 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.
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 flow for the GFR series as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your line pressure and air demand and we will confirm the datasheet curve figures for this exact model on request.
The A in the code means the bowl drains condensate automatically, so collected water is expelled without an operator or a pressure drop having to trigger it - useful where the unit is not checked daily. The W in the code selects the 5 um filter element instead of the 40 um standard, for finer removal of particulate ahead of sensitive downstream components.
