The AirTAC GFR400C15MLC2T AirTAC Filter Regulator NPT1/2 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 AirTAC GFR400C15MLC2T is a GFR-series filter regulator: water and particulate filtration plus pressure regulation in a single body, sized 400 with 1/2 in NPT ports. This configuration carries the standard 40 um filter element, a manual drain on the bowl, the low-pressure regulator type, and a round external gauge reading in psi. A mounting bracket is included. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600, with port options from 1/8 to 1 in, PT as the standard thread and G (BSPP) or NPT as order options, a choice of 40 um or 5 um (W) filtration, manual, automatic or differential-pressure drains, and gauge or no-gauge builds. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

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.

Fixture clamps and swing cylinders that must run at a reduced, stable setting take filtered air from the 40 um element and a set pressure from the low-pressure regulator, with the round psi gauge giving the operator a direct reading at the cell.
Blow-off nozzles and air knives on packaging lines need clean, moisture-reduced air held at a gentle setting; the GFR400 body does both jobs in one footprint, and the manual drain suits a line that is blown down at shift end.
Machine-tool and CNC peripheral panels fed at 1/2 in take this unit ahead of directional valves and cylinders, removing water and pipe scale with the 40 um element while the low-pressure regulator holds the circuit at its working setting.
Step up or down through the GFR sizes (200 / 300 / 400 / 600) to match the port and flow band your line needs; this unit is size 400 with 1/2 in NPT threads. Choose the drain to suit maintenance habits: manual drain (this model) means an operator drains the bowl on a schedule, while automatic and differential-pressure drains look after themselves. The 40 um element is the standard grade; specify W for the 5 um grade where finer filtration is required. Gauge scale is selectable (MPa, psi or bar) and this build ships with the round external gauge in psi. Thread is NPT here; PT is the catalogue standard and G (BSPP) is also available to order. Because flow is published as curves and not a single rating, send us your application details 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 GFR performance as flow curves rather than a single rated figure, so we do not quote a l/min, m3/h or SCFM number for this unit. Tell us your application and we will confirm the flow curve and datasheet figures for the GFR400 size on request, and help you check whether size 400 at 1/2 in NPT is the right step for your demand.
In the code GFR400C15MLC2T, M selects the manual drain (you drain the bowl yourself on a schedule, instead of the automatic or differential-pressure drain options), and C2 selects the optional external round gauge with a psi scale; the embedded square gauge is the standard build and MPa or bar scales are also available. The L sets the low-pressure regulator type, whose exact adjustment range is not published - we will confirm it on request.
