The AirTAC GFR400C15MLC2WT AirTAC Filter Regulator NPT1/2 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 AirTAC GFR400C15MLC2WT is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built around a 1/2 in NPT port, the 5 um filter element (code W, against the 40 um standard), a manual drain on the metal bowl, and the low-pressure regulator type (code L). It is fitted with a round pressure gauge reading in psi, includes a mounting bracket, and has no reverse/check valve.
This is a genuine AirTAC part in the GFR400 size class, rated for a maximum inlet pressure of 1.0 MPa (145 psi) and operating at -5 to 70 C in non-freezing conditions. The GFR400 series is offered in a range of ports, drain types, filter grades, gauge styles and thread options; because flow is published as curves rather than a single rating, we confirm figures from the datasheet 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. 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 the clamp cylinders on a CNC fixture line: the 5 um element keeps water and debris out of the clamping valves, and the low-pressure regulator type is chosen where the fixture calls for a low set pressure.
A bench supply for pneumatic test rigs and lab apparatus where a set-and-read regulated pressure and fine 5 um air are required; the round psi gauge gives a direct readout when setting up a test.
Feeding directional valves and small cylinders on a packaging or conveyor line: the manual-drain metal bowl is drained during scheduled line stops, and the included bracket mounts the unit at the line drop.
Size and port are the first decision: the GFR400 size with a 1/2 in NPT port suits lines plumbed at that bore, and stepping up or down in size changes both port and flow capacity - since flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. Filter grade is a real choice: 40 um is the standard element and 5 um (code W) is the finer option fitted here, worth selecting where downstream valves, cylinders or instruments are sensitive to carryover. Drain type is another: manual (fitted here) means draining the bowl by hand on a schedule you control, while automatic and differential-pressure drains are available elsewhere in the range.
Gauge and thread complete the decode: this unit carries a round gauge with a psi scale (an embedded square gauge and MPa or bar scales are the alternatives), the trailing T sets NPT thread, where PT is the AirTAC standard and G (BSPP) is the other order option. The low-pressure regulator type (L) is selected where the application calls for a low-pressure regulated setting; its exact adjustment range is not published in our current data and is confirmed on request. A mounting bracket is included.
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, not as a single rated figure, so we do not quote a number here. Send us your line pressure, port size and downstream demand and we will confirm the flow and sizing from the datasheet on request.
The L code marks the low-pressure regulator variant, selected where the application calls for a low-pressure regulated setting rather than the standard type. The exact adjustment range for this variant is not published in our current data, so we confirm it on request before you order. The rest of the code decodes as: 1/2 in NPT port, 5 um filter element, manual drain, and a round gauge with a psi scale.
