The AirTAC GFR60020ALJC2WGK 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 GFR60020ALJC2WGK is a GFR-series filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This size-600 unit has a G3/4 (BSPP) port, a 5 um filter element, an automatic drain, and the low-pressure regulator type. A round gauge scaled in psi is fitted, a reverse/check valve is included in the code, and the unit is supplied without a mounting bracket. 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 line spans sizes 200 to 600 with ports from 1/8 to 1 inch, drain choices (differential-pressure, automatic or manual), 40 um standard or 5 um (W) filtration, gauge and thread options, and an aluminium-alloy bowl at size 600. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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. |
| J | Supplied without bracket. |
| (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.

Point-of-use filter regulator on the air drop feeding capping and labeling heads on a beverage bottling line, keeping water and debris out of the valves while holding a steady low-pressure setting for the machine's actuators.
Supply unit for a machining-cell clamping fixture: the 5 um element protects the directional valves and clamp cylinders, the low-pressure regulator holds the fixture setting, and the round psi gauge gives the operator a local reading.
Air preparation for diverter and stopper cylinders on a parcel-sort conveyor, where the automatic drain handles condensate from a long supply run and the G3/4 port serves the larger cylinder volume at the line drop.
Step up through sizes 200 to 600 as your flow demand grows; this code is the size-600 step with a G3/4 port. Choose the drain - differential-pressure (default), automatic (as here) or manual. Filtration is 40 um standard or 5 um with the W code, fitted on this unit. Gauges are offered with MPa, psi or bar scales, and threads can be ordered in PT (standard), G or NPT; brackets are optional. Maximum inlet pressure is 1.0 MPa (145 psi) and working temperature is -5 to 70 C, non-freezing. Flow is published as curves, not a single rating, so 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.
AirTAC publishes GFR flow 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 flow curve and sizing for the GFR600 at G3/4 before you order.
The W code in GFR60020ALJC2WGK selects the 5 um element instead of the 40 um standard, for finer protection of downstream valves and cylinders. The A code selects the automatic drain, which discharges condensate without manual attention; differential-pressure and manual drains are available on other codes in the series.
