The AirTAC GFR400C15MJF2WT AirTAC Filter Regulator NPT1/2 5um 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 GFR400C15MJF2WT is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and holds a regulated downstream pressure in a single body. This configuration is built for a 1/2 in NPT port, runs the finer 5 um filter element (code W against the 40 um standard), drains the bowl manually, and carries the embedded square gauge scaled in psi. The standard regulator covers a setting range of 0.05-0.9 MPa (7-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the 400 frame uses a metal bowl. Operating temperature is -5 to 70 C, non-freezing. No reverse/check valve is fitted and the unit is supplied without a mounting bracket.
This is a genuine AirTAC part. The GFR filter-regulator line spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options include automatic or differential-pressure draining, the 40 um standard element, external round gauges with MPa, psi or bar scales, G (BSPP) or NPT threads in place of the PT standard, and a mounting bracket. Flow 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 for a bench or pneumatic press: the 5 um element keeps water and swarf out of the valve and cylinder, while the regulator holds a steady downstream setting read directly on the psi-scaled square gauge.
Filtered, regulated air for actuated diverters, pushers and sealing jaws along a packaging conveyor; manual drain suits a line that is blown down at the start and end of each shift.
Clean, set-and-read air for a laboratory or test-rig skid: 5 um filtration protects sensitive instruments and fittings, and the psi gauge lets technicians verify the regulated setting at a glance.
Size and port come first: the 400 frame with a 1/2 in port sits in the upper-middle of the GFR range (200, 300, 400, 600), and the right step depends on the air your line consumes - we confirm sizing from the published flow curves before you order. Drain type matters: this unit is manual drain, which suits attended installations where an operator blows the bowl down on a routine; choose automatic or differential-pressure draining for unattended duty. The 5 um element (W) is the finer option against the 40 um standard - pick 5 um where downstream valves and instruments need cleaner air. The embedded square gauge on this unit reads in psi; external round gauges with MPa, psi or bar scales are optional. Thread here is NPT (PT is the standard; G/BSPP and NPT are order options), and no mounting bracket is included - add one if you panel- or wall-mount the unit.
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 as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure, downstream setting and air demand, and we will confirm the flow and sizing from the datasheet before you order.
Manual drain means an operator opens the drain to expel the water collected in the bowl, which suits attended installations on a regular blow-down routine. If the unit will run unattended, ask us about the automatic or differential-pressure drain versions of the same GFR400 frame.
