The AirTAC GFR60020LF2TK AirTAC Low-Pressure Filter Regulator NPT3/4 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 GFR60020LF2TK is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This size 600 unit carries a 3/4 in NPT port and the low-pressure regulator type for circuits that run at reduced settings. Filtration is the 40 um standard element, the drain is the differential-pressure type, and the embedded square gauge is fitted and reads in psi. A reverse (check) valve is built in, the aluminium alloy bowl suits this largest frame, a mounting bracket is included, maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 to 1 in, drain choices (differential-pressure, automatic or manual), an optional 5 um element (code W), gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures for your application on request.

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.

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.

Conditioning the supply to the gun and actuation circuits of a paint or powder-coating line, where the low-pressure type holds reduced settings, the 40 um element screens particles ahead of the equipment, and the psi gauge gives operators a direct line-side reading.
Feeding the cylinder and air-mover circuits on a packaging conveyor, with the built-in check valve helping hold the downstream circuit if upstream supply dips and the square gauge letting staff verify set pressure at a glance.
Serving as the conditioning stage of a pneumatic control panel: filtering plant air and regulating it down to the reduced pressure the panel valves need, with the included bracket fixing the 3/4 in unit to the backplate.
Match the 3/4 in NPT port to your piping; sizes 200 to 600 step up in port and flow capacity, and the published flow curves - not a single rated figure - are the reference, so send us your demand and we will confirm sizing before you order. This code fixes the real choices for you: the low-pressure regulator type, the 40 um standard element, the differential-pressure drain, the square gauge on the psi scale and the built-in check valve. PT is the standard thread and G or NPT are catalogue options, with NPT already selected here; a mounting bracket is included.
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 GFR flow as curves, not a single rated figure, so we do not quote a number here. Send us your line pressure and air demand and we will confirm sizing for this unit from the datasheet on request.
K means a reverse (check) valve is fitted: air passes one way through the unit and the valve helps hold the downstream circuit if upstream supply drops. The rest of the code decodes as size 600, 3/4 in NPT port, low-pressure regulator type, square gauge on the psi scale, differential-pressure drain and 40 um filter element.
