The AirTAC GFR60020LJC3WT AirTAC Filter Regulator NPT3/4 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 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 GFR60020LJC3WT is an AirTAC GFR600 filter regulator: a 5 um filter element and a pressure regulator combined in one body, so the compressed air is cleaned of water and particulate and then regulated in a single pass. This unit is built for 3/4 in NPT ports, uses the W-code 5 um element instead of the standard 40 um, drains collected condensate by differential pressure, and is the L-code low-pressure regulator type. It is fitted with a round pressure gauge reading in bar, has an aluminium alloy bowl (the size 600 material), and comes without a mounting bracket or a reverse/check valve. 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 family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options for drain type (differential-pressure, automatic or manual), filter grade (40 um standard or 5 um), gauge style and scale, G/NPT threads and brackets. Flow is published as curves rather than a single rated figure, 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". |
| (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. |
| (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.

Feeding spray guns on an automotive refinish booth: the 5 um element strips water and grit before the gun, and the low-pressure regulator holds a gentle, steady setting for fine finishing work.
Supplying grippers, pushers and stopper cylinders on a bottling conveyor: one unit filters and regulates in a single pass, and the differential-pressure drain bleeds off collected condensate while the line runs.
Driving low-pressure blow-off nozzles that dry cans before labelling: the low-pressure regulator type suits gentle settings, and the 3/4 in NPT ports tie straight into the main drop leg.
Size and port set the air capacity: this is size 600 with 3/4 in NPT threads, the largest GFR frame, so step up or down (200/300/400/600) to match the line size and demand. The real, decodable choices on this family are: drain type (differential-pressure as here, automatic, or manual), filter element (40 um standard or 5 um with the W code), gauge style (embedded square standard, external round optional) and scale (MPa, psi or bar - this unit carries a round gauge reading in bar), thread (PT is the series standard; G and NPT are order options, NPT here), and bracket (included by default, omitted with the J code). The L code makes this the low-pressure regulator type; its exact adjustment range is not published, so confirm it with us. Because flow is published as curves rather than one rated number, ask us to check sizing against your application before ordering.
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 GFR600 as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure and air demand and we will confirm the sizing from the datasheet on request.
Yes. G (BSPP) is a catalogue order option alongside NPT, and PT is the standard thread for the series. This unit is specified with 3/4 in NPT ports; order the G-thread variant if your pipework is BSPP.
