The AirTAC GFR600C20LJF1T AirTAC Filter Regulator 3/4 in NPT 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 See datasheet 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 GFR600C20LJF1T is a 600-size filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has 3/4 in NPT ports, the standard 40 um filtration grade, a differential-pressure drain on the bowl, and a low-pressure regulator type with an embedded square gauge reading in MPa. The bowl on this 600 size is aluminium alloy, and the unit is supplied without a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, a 40 um standard or 5 um (W) filter grade, MPa, psi or bar gauge scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the figures and datasheet 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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.

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.

Point-of-use preparation ahead of spray booths and air-assisted guns, where water and dirt must be stripped out and the line held at a low, stable working pressure.
Feeding the flap-press and case-clamp cylinders on a packaging conveyor, with the 3/4 in port serving a larger header that supplies several stations.
Filtered, low-pressure regulated air for pneumatic quarter-turn actuators on process valves in a treatment or dosing skid.
Start with the port step: this unit is the 600 size with 3/4 in NPT ports, the largest in the GFR range - step down to 200/300/400 with 1/8 in to 1/2 in ports if your line is smaller, and match the size to the flow your circuit needs. The drain here is differential-pressure (the default); automatic (A) or manual (M) drains are order options if you prefer. The 40 um element is standard; specify code W for the 5 um grade where finer filtration is required. The gauge is the embedded square type with an MPa scale, and psi or bar scales can be ordered instead. Thread is NPT here; PT is the standard thread and G (BSPP) is also a catalogue option. Bracket: this code carries no bracket (J).
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated figure, so send us your application details and we will confirm the flow and datasheet figures 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 family as performance curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure and the flow your circuit needs, and we will confirm the sizing against the datasheet curves before you order.
The L code makes this a low-pressure regulator variant rather than the standard type; the exact adjustment range for the low-pressure version is not published in the sheet, so we confirm it on request. Drainage is the differential-pressure type (the default code), which bleeds the bowl automatically as flow passes; automatic (A) and manual (M) drains are available as order options.
