The AirTAC GFR60020LJF2G AirTAC Filter Regulator G3/4 Low-Pressure is a genuine G-series filter regulator: water separation, 40 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 GFR60020LJF2G is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size-600 unit has a G3/4 port with G (BSPP) thread, a 40 um standard filter element, and the differential-pressure drain that is the default for this family. It is the low-pressure regulator type, fitted with an embedded square gauge scaled in psi, and no mounting bracket is included (code J). Because it is size 600, the bowl is aluminium alloy. 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 to 1 inch, and is available with automatic (code A) or manual (code M) drains, a finer 5 um element (code W), alternative gauge scales, G or NPT thread as order options, and an optional bracket. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

| 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). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 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.

Feeding filtered, regulated air to spray guns and air-assisted applicators in a paint or coating booth, where the low-pressure regulator type holds a gentle set point downstream of the compressor ring main.
Supplying clean, regulated air to laboratory and workshop test stands that run pneumatic fixtures at reduced pressure, with the square psi gauge giving a direct local readout of the set point.
Point-of-use preparation for cylinders and air grippers on a carton-sealing or labelling conveyor, combining water and particulate removal with pressure regulation in one G3/4 drop from the main.
Choose the size by port and required flow: this unit is size 600 with a 3/4 in G-thread port, the largest step in the range. Drain options are differential-pressure (this unit), automatic (code A) and manual (code M). The filter element is 40 um as standard; specify code W for 5 um where finer filtration is needed. The gauge here is the embedded square type scaled in psi; an external round gauge and MPa or bar scales are the other catalogue choices. Thread is G (BSPP); PT is the standard thread and NPT can be ordered as an option. This is the low-pressure regulator type and its exact regulating range is not published, so confirm your set pressure with us before ordering. Flow is published as curves, not a single rating - ask us to confirm sizing against the application 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 number here. Tell us your line pressure and air demand and we will confirm the sizing from the datasheet on request.
The L in GFR60020LJF2G marks the low-pressure regulator variant of the GFR family, intended for circuits set below the standard type's range. Its exact regulating range is not published in the catalogue, so confirm your set pressure with us before ordering. Everything else decodes normally: G3/4 port, G thread, 40 um element, differential-pressure drain, square psi gauge, no bracket.
