The AirTAC GFR400C15MLC2WG AirTAC Filter Regulator G1/2, 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 GFR400C15MLC2WG is an AirTAC GFR400 filter regulator: a 1/2 in (G1/2) unit that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries the 5 um filter element (code W), a manual drain, the low-pressure regulator type, an external round gauge scaled in psi, and the included mounting bracket; no reverse/check valve is fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The bowl on this size is polycarbonate (PC).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of differential-pressure (default), automatic or manual drain, 40 um standard or 5 um (W) filtration, gauge and scale options, and PT (standard), G or NPT threads to order. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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 air prep feeding pneumatic cylinders on a carton-forming conveyor, where the 5 um element keeps water and grit out of seals and valves and the low-pressure regulator holds a gentle set pressure for delicate product handling.
Conditioning compressed air for lab benches, sample-handling actuators and analytical instruments that need particulate- and water-filtered air regulated to a low, stable setting, with the round psi gauge giving a direct local readout.
A compact air-prep station for a small assembly cell: the manual drain suits a shift pattern where an operator bleeds the bowl at start-up or shutdown, and the included bracket mounts the unit neatly to the cell panel.
Size and port step up with air demand: this unit is size 400 with G1/2 ports; size 600 gives a larger port and more flow, while 200 and 300 suit lighter duty. Drain choice matters: manual drain (this unit) is emptied by hand at intervals, automatic drain handles condensate by itself, and the differential-pressure default drains on a pressure drop. Filter grade is 5 um here (code W); the 40 um standard element is the choice when finer filtration is not required. The gauge on this unit is the external round type scaled in psi; an embedded square gauge and MPa or bar scales are the alternatives. Thread is G (BSPP); PT is the standard thread and G and NPT are catalogue order options. A low-pressure regulator type is fitted, and its set-pressure range is confirmed from the datasheet on request. Because flow for this series is published as curves, not a single rating, ask us to check sizing against your application before ordering.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. 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 GFR400 series as curves rather than a single rated number, so there is no one figure we can quote. Tell us your working pressure and air demand and we will confirm the flow from the datasheet for this exact configuration before you order.
This unit has a manual drain: an operator opens it periodically to expel collected condensate, which suits lines with regular shutdowns. If you prefer hands-off condensate removal, the same GFR400 size is available with an automatic drain or the differential-pressure default - ask us for that variant.
