The AirTAC GFR600C20MLJF2WK AirTAC Filter Regulator 3/4 in PT 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 GFR600C20MLJF2WK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This size 600 unit carries a PT3/4 port, a 5 um filter element (code W), a manual drain, and a metal bowl - aluminium alloy at size 600. It is the low-pressure (L) type, has an embedded square gauge reading in psi, includes a reverse (check) valve, and is supplied without a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, plus options for drain type, 40 um or 5 um filtration, gauge scale, G or NPT thread, and bracket. Flow is published as curves rather than a single rating, so ask us to confirm figures against your application and we will send the datasheet on request. Operating limits: max inlet pressure 1.0 MPa (145 psi); temperature -5 to 70 C (non-freezing).

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.

Clean, regulated air feeding pneumatic clamps and fastening drivers along a final-assembly line, with the check valve holding downstream pressure if supply dips.
Point-of-use filtration and regulation for tool-change actuators, clamping fixtures and blow-off nozzles on a machining centre, with 5 um filtration protecting fine valve spools.
Conditioned air for sealing jaws, diverters and gripper cylinders on a packaging conveyor, with the manual drain emptied during scheduled changeovers.
The real, decodable choices on this family: step through sizes 200/300/400/600 to match your port and the flow your line needs (flow is published as curves, not a single rating - we confirm sizing on request); drain type, where differential-pressure is the default and automatic or manual are the options (this unit is manual, so condensate is drained by hand); filter grade 40 um standard or 5 um with code W (this unit is 5 um for finer particulate); gauge scale MPa, psi or bar (this unit: square gauge, psi); thread PT as standard with G and NPT as order options; bracket included or omitted (this unit: no bracket). This is the low-pressure (L) type, so tell us your working pressure and we will confirm suitability 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 as curves, not a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow from the GFR600 datasheet on request, including the curve relevant to this low-pressure type.
The L marks the low-pressure regulator variant, intended for circuits working below the standard regulator's range; the exact adjustment range for this variant is not published in the sheet we transcribe, so ask us to confirm it against your set pressure before ordering. Separately, the M in the code means the bowl has a manual drain: condensate is drained by hand during maintenance rather than automatically.
