The AirTAC GFR60020LJF2K AirTAC Filter Regulator PT3/4 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 GFR60020LJF2K is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This 600-size unit is fitted with a 3/4 in PT port, the low-pressure regulator type, a 40 um standard filter element, and a differential-pressure drain that bleeds accumulated condensate automatically as the pressure differential across the element builds. The embedded square gauge reads in psi, a reverse/check valve is fitted to hold downstream pressure, and no mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with a choice of ports, drain types, 40 um or 5 um filtration, gauge scale and thread options, so a configuration can be matched to most supply lines. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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.

| (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. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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.

Mounted at the drop feeding a fixture-clamping circuit, the unit strips water and chips-laden condensate from the shop air and holds the clamping pressure steady through the cycle, with the check valve holding the circuit if supply dips.
Installed on the 3/4 in branch line serving a packaging line's air cylinders and sealers, it conditions the supply and regulates it to the level the machine's valve train expects, with the psi gauge giving operators a local reading.
Used ahead of a manifold feeding low-pressure actuators or air-driven controls, the low-pressure regulator type lets the panel run at a gentler setting than a standard unit is tuned for, while the 40 um element protects the downstream components.
Size 600 with a 3/4 in PT port is the largest step in the GFR range, so start there when the line serves high-demand actuators or several branches, and step down to 300/400 where demand is lighter. The low-pressure regulator type in this code suits circuits held below standard regulating ranges; confirm the working band you need with us before ordering, since the exact range for the low-pressure type is not published on the datasheet summary. Filtration is the 40 um standard element; choose the W-code 5 um element only where downstream valves demand finer air. The differential-pressure drain is hands-off; a manual-drain code suits lines that are shut down regularly, and an automatic drain suits continuously running plant. This unit carries a square gauge reading psi (MPa and bar scales are alternatives), a fitted reverse/check valve, no bracket, and PT thread as standard with G and NPT available as order options. Flow is published as curves, not a single rating, so send us your demand figures and we will confirm sizing 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 series as curves, not as a single rated number, so we do not quote a figure here. Tell us your line pressure and the air demand of the equipment you are feeding, and we will confirm the sizing from the datasheet curves before you order.
The L in the code marks the low-pressure regulator type, intended for circuits held below the standard regulating band; the exact range for this type is not published in the summary sheet, so confirm your working pressure with us. The K marks a reverse/check valve fitted in the body, which holds downstream pressure if the upstream supply is lost.
