The AirTAC GFR400C15MC2T AirTAC Filter Regulator 1/2 in NPT 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 GFR400C15MC2T is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in a single body. This 400-size unit has a 1/2 in NPT port, a manual drain on the polycarbonate bowl, a 40 um standard filter element, and a round pressure gauge reading in psi. The standard regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). A mounting bracket is included.
This is a genuine AirTAC part from the GFR series, which spans sizes 200 to 600 with ports from 1/8 to 1 in, and options including automatic or differential-pressure drains, a 5 um (W) filter element, G (BSPP) or NPT threads, and square or round gauges in MPa, psi or bar scales. Flow for this model is published as a curve 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.

Installed at the drop to a CNC machining cell, it filters condensed water and particulate from shop air and holds a steady setpoint for the machine's pneumatic valves and clamps.
Mounted on the supply line feeding carton-sealing and case-packing cylinders, it keeps actuator pressure consistent through the shift while the manual drain lets maintenance bleed accumulated water at planned stops.
Fitted at workshop bench drops, it delivers filtered, regulated air to impact wrenches, blow guns and paint guns, with the psi gauge giving technicians a visible setting for each bay.
Choose the size and port against the air your application consumes: 400 size carries a 1/2 in port, and larger sizes move more air - we can confirm the flow curve against your demand before you order. This unit has a manual drain, so the bowl is bled by hand; automatic and differential-pressure drain variants exist in the same series if you prefer unattended draining. The 40 um element is standard; specify code W for a 5 um element where downstream equipment needs finer filtration. The fitted round gauge reads in psi; embedded square gauges and MPa or bar scales are alternatives. PT is the standard thread for this series, with G (BSPP) and NPT as orderable options - this unit is specified with NPT. 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 GFR series as curves rather than a single rated figure, so we do not quote a number here. Tell us your application and required flow and we will confirm the datasheet curve and correct sizing on request.
The M in the code specifies a manual drain: the bowl is bled by hand, which suits lines with regular maintenance stops. The same GFR400 series is also available with automatic or differential-pressure drains - ask us and we will decode the right variant for you.
