The AirTAC GFR400C15MLJC1TK 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 GFR400C15MLJC1TK is a filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This size 400 unit comes with 1/2 in NPT ports, a manual-drain metal bowl, the standard 40 um filter element and the low-pressure regulator type. A round MPa gauge is fitted, a reverse (check) valve is built in, and the unit is supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR range spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and can be ordered with manual, automatic or differential-pressure drains, 40 um or 5 um (W) elements, embedded square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application 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.

| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |

| (blank) | Pressure gauge fitted (blank). |
| (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. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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.

A filtered, regulated supply for clamp cylinders and vises on a CNC machining line, with the built-in check valve fitted in the circuit and the 40 um element keeping water and swarf-borne particulate out of the valves.
Conditioning the air feed to spray equipment on a paint or coating line, where the low-pressure regulator type and a manual-drain bowl suit a booth that is checked as part of a supervised routine.
Filtering and regulating air for the cylinders that divert, push and seal packs on a packaging conveyor, with the 1/2 in NPT connection tying straight into the machine's main air drop.
Every choice in this range is decodable from the code. Step across sizes 200/300/400/600 and ports 1/8 to 1 in to match your pipework and the flow your line needs. Drains: manual (this unit - the bowl is drained by hand), automatic, or differential-pressure. Filter grade: 40 um standard, 5 um with code W. Gauges: embedded square as standard or external round, scaled in MPa, psi or bar. Thread: PT is the standard, with G (BSPP) and NPT as order options, and brackets are optional. Flow is published as curves, not a single rating, so send us your flow and pressure requirements and we will confirm sizing against the datasheet before you order.
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 GFR range as curves rather than a single rated figure, so we do not quote a number here. Send us your flow and upstream/downstream pressure requirements and we will confirm the datasheet figures for this size 400, 1/2 in NPT unit on request.
The M in the code sets a manual drain: the bowl is drained by hand as part of routine checks. The same GFR400 size can be ordered with an automatic (A) or differential-pressure drain instead, with a 5 um element (W) for finer filtration, and with psi or bar gauge scales in place of the MPa scale fitted here.
