The AirTAC GFR60020LJC3WTK AirTAC Filter Regulator NPT3/4 5um 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 GFR60020LJC3WTK 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 3/4 in NPT ports, carries the fine 5 um filter element (code W), drains condensate automatically by differential pressure, and is the low-pressure regulator type. It comes fitted with an external round gauge scaled in bar and a reverse/check valve, and has an aluminium alloy bowl. No mounting bracket is included, so plan to mount it on the connected pipework or a customer-supplied bracket.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in and a choice of PT, G (BSPP) or NPT threads. Drain types, filter grades, gauges and regulator options are selectable per code. Rated flow for this family is published as curves rather than a single figure, so ask us to confirm the datasheet and sizing for 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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| (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. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT 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.

Feeds cylinders and air actuators on a machine that runs at reduced regulated pressure, with the 5 um element protecting directional valves and the check valve holding the downstream circuit on supply loss.
Installed at the 3/4 in drop feeding a packaging line, cleaning water and particles from the shop air and holding a steady low regulated pressure to the machine's air valves.
Mounted in a control panel air supply where a fine 5 um grade and a local bar-scaled gauge are wanted, with the differential-pressure drain removing accumulated condensate during operation.
Choose the GFR600 size when your line runs 3/4 in piping and you want filter and regulator in one body instead of two separate components. Within the family you can step down to sizes 200/300/400 for smaller ports, select the 40 um standard element or the 5 um fine element (W) for this unit it is the 5 um grade, pick differential-pressure, automatic or manual draining, and specify the gauge: an embedded square gauge is standard and an external round gauge is optional, with MPa, psi or bar scales. Thread is PT as standard, with G (BSPP) and NPT as order options; bracket inclusion is also a code choice. One honest note on sizing: AirTAC publishes flow for this family as curves, not a single rated number, so send us your application details and we will confirm the right size against 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 GFR family as performance curves rather than a single rated figure, so we do not quote a number here. Tell us your inlet pressure and the flow your application needs, and we will confirm the datasheet curve and check the sizing for you before you order.
The L in the code marks the low-pressure regulator type, intended for applications regulated below the standard type's range. The exact regulation range for this low-pressure variant is not published in our sheet, so please ask us to confirm it against the datasheet. Everything else in the code is standard decode: 3/4 in NPT ports, 5 um element, differential-pressure drain, round bar gauge and a fitted check valve.
