The AirTAC GFR600C20MLJF2K AirTAC 3/4" Filter Regulator, 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 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 GFR600C20MLJF2K is an AirTAC GFR filter regulator: a 3/4 in PT unit that removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 configuration has a manual drain, a 40 um standard filter element, an aluminium alloy bowl, the low-pressure regulator type, an embedded square gauge reading in psi, and a built-in check valve (code K); it is supplied without a mounting bracket.
It is a genuine AirTAC part, one of the GFR sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in. Family options include a 5 um element (code W), automatic or differential-pressure drain, G or NPT thread, alternative gauge scales, and a mounting bracket. 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.

| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 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.

Filtered, pressure-controlled 3/4 in air to an air-over-oil stamping press, with the built-in check valve fitted for circuits that need to hold their regulated side.
A conditioned drop on a lab air main feeding actuators and air benches, where the 40 um element, psi gauge and manual drain suit a supervised indoor installation.
Filtering and regulating air to carton-sealing and case-packing cylinders on a packaging conveyor, with the embedded square gauge giving operators a local setpoint readout.
Within GFR you step through sizes 200, 300, 400 and 600 - larger size, larger port and more flow - so match the 3/4 in PT porting here to your line size and air demand. Choose the drain: manual (this unit, code M), automatic (A) or differential-pressure (blank); manual means the bowl is drained by hand on a routine you set. The 40 um element is standard and a 5 um grade (W) is available where finer filtration is needed. Gauge scale (MPa, psi or bar), G or NPT thread in place of the PT standard, and a mounting bracket are all orderable options. This is the low-pressure regulator type; its exact adjustment range is not published in the catalogue, so confirm it with us against your set pressure before ordering. Flow is published as curves, not a single rating - ask us to confirm sizing from the datasheet.
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 GFR flow as curves rather than a single rated figure, so no rated flow, Cv or SCFM number is quoted here. Tell us your application and we will confirm the flow figures from the datasheet on request.
Code M means the bowl is drained by hand on a routine you set. The GFR family also offers automatic (A) and differential-pressure (blank) drains, so you can specify an unattended drain in the same size if the installation suits it.
