The AirTAC GFR600C20LJF2WGK AirTAC Filter Regulator G3/4, 5 um 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 GFR600C20LJF2WGK is an AirTAC GFR600 filter regulator: a 3/4-inch (G3/4, BSPP) unit that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 5 um filter element (code W), a differential-pressure drain, a low-pressure type regulator, an embedded square gauge with a psi scale, and a built-in reverse (check) valve; no mounting bracket is included. At size 600 the bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 to 1 inch, drain choices (differential-pressure, automatic, manual), 40 um standard or 5 um filtration, gauge scales in MPa, psi or bar, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm figures from the 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.

Filtered, regulated air to pneumatic clamps and swing cylinders on a machining cell, with the 5 um element protecting valve and seal surfaces and the built-in check valve blocking reverse flow.
Point-of-use air preparation for the sealing, tucking and diverting cylinders on a carton or bag line, giving the machine its own local filter, regulator and psi gauge at the drop.
A filter regulator at each workbench drop on an assembly floor, so operators get clean air and can set tool supply pressure locally on the square psi gauge.
Size 600 with a G3/4 port is the largest step in the GFR range; step up or down (200/300/400/600) to match your piping and the flow your line needs. This code fixes the real choices: a 5 um element instead of the 40 um standard, differential-pressure drain, low-pressure type regulator, square gauge on the psi scale, G (BSPP) thread instead of the PT standard (NPT is also an order option), check valve fitted, and no bracket. AirTAC publishes flow as curves rather than a single rated figure, so send us your application details and we will confirm sizing from the datasheet before you order. The exact adjustment range of the low-pressure type is not published in the catalogue; we can confirm it on request.
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, not as a single rated figure, so we do not quote a number here. Send us your line pressure, port size and air demand and we will confirm the flow from the datasheet on request.
L marks the low-pressure type regulator. The catalogue does not publish an exact adjustment range for this variant, so we confirm it on request rather than quoting the standard GFR range for this code.
