The AirTAC GFR600-20LJF2WGK 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 differential-pressure 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 GFR60020LJF2WGK is a size-600 GFR filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built for a 3/4 in G (BSPP) port, carries the fine 5 um filter element (code W) instead of the 40 um standard, and is the low-pressure type for circuits that run below standard regulator settings. It ships with the embedded square gauge scaled in psi, a reverse/check valve fitted, and the differential-pressure drain that bleeds collected condensate automatically as flow passes through. At size 600 the bowl is aluminium alloy, and no mounting bracket is included with the J-code build.
This is a genuine AirTAC part from the G-series air-treatment line, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, thread choices of PT (standard), G and NPT, drain types, filter grades and gauge scales. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm sizing or any datasheet figure against 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.

| (blank) | Drain: Differential-pressure 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. |

| 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.

On a beverage bottling line, this 3/4 in filter regulator conditions the air feeding gripper and capping-head actuators, with the 5 um element protecting fine valve spools and the low-pressure type matching gentle clamp circuits.
A machining-centre pallet-clamp circuit that must hold a fixed, moderate pressure benefits from the low-pressure regulator type, while the check valve holds the set pressure if upstream supply dips mid-cycle.
Air-driven diverter and pusher cylinders on a packaging conveyor get clean, regulated air from this unit; the psi-scaled square gauge lets line staff verify set pressure at a glance and the differential-pressure drain keeps condensate off the valves.
Step up or down through the G-series sizes (200/300/400/600) to match the port and the flow your line needs; this unit is the 600 size with a 3/4 in G thread. Choose the drain type where it matters: differential-pressure (fitted here) drains with flow, automatic drains whether or not air flows, and manual needs a operator to bleed the bowl. The 5 um element (code W) suits instruments and finer pneumatic work; the 40 um standard element covers general supply. Gauge scale (MPa, psi or bar - psi here) and the embedded-square versus external-round gauge are decodable choices, as are PT versus G/NPT threads and the bracket option (not fitted on this J-code unit). Because flow is published as curves and not a single rated figure, send us your application details and we will confirm sizing from the datasheet 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 G-series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and the air demand of your equipment and we will confirm sizing for this 3/4 in, size-600 unit from the datasheet on request.
The W in the code selects the 5 um filter element instead of the 40 um standard, which suits circuits with sensitive valves or instruments, and the L selects the low-pressure regulator type for circuits that run below standard settings. The exact low-pressure adjustment range is not published in the catalogue sheet we work from, so we will confirm it on request.
