The AirTAC GFR400C15MF2WGK AirTAC Filter Regulator 1/2 in 5 um 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 GFR400C15MF2WGK is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and holds a set downstream pressure in one body. This configuration has a G1/2 (BSPP) port, a 5 um filter element, a manual drain on the polycarbonate bowl, a fitted reverse (check) valve, and an embedded square gauge reading in psi. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and a mounting bracket is included. Medium is compressed air only, with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options include manual, automatic or differential-pressure drains, 40 um or 5 um elements, gauge scale choices, and G or NPT threads. Flow for this series is published as curves rather than a single rated figure, so ask us and we will 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.

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 for pneumatic clamps and tool-change cylinders on a machining centre, with the 5 um element protecting downstream valves from fine particulate.
Steady set pressure for diverters, sealers and pusher cylinders on a packaging conveyor, with the fitted check valve holding the circuit against backflow.
Clean, repeatable air supply for a lab or QC bench where the operator sets pressure on the psi gauge and drains the bowl manually after each run.
Size 400 with a 1/2 in port sits in the upper half of the GFR range; step down to size 300 or up to size 600 depending on the air demand of your line - because flow is published as curves, send us your requirement and we will confirm sizing before you order. This unit is manual-drain, so plan a routine bowl-drain check; automatic and differential-pressure drain versions are available if you would rather not drain by hand. The 5 um element (code W) suits points of use that need cleaner air than the 40 um standard. The square gauge reads in psi; MPa and bar scales are options. The thread here is G (BSPP) - PT is the standard thread and NPT can be ordered as a specification option. 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, not as a single rated number, so we do not quote a figure here. Tell us your inlet pressure, set pressure and expected air demand, and we will confirm the sizing from the datasheet on request.
Manual drain means someone opens the bowl drain periodically to remove collected water. Choose it where the unit is easy to reach and condensate is moderate; choose the automatic or differential-pressure drain option where the bowl is hard to access or the air carries a heavier water load.
