The AirTAC GFR400C15MF2WG AirTAC Filter Regulator G1/2, 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 AirTAC GFR400C15MF2WG is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a G1/2 (BSPP) port, a 5 um filtration element for finer air quality than the 40 um standard element, a manual drain for emptying the bowl by hand, and an embedded square gauge reading in psi. The standard regulator covers an adjustment range of 0.05-0.9 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, and the polycarbonate bowl suits this size in the G-series range.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8" to 1", and with choices of drain type, filtration grade (40 um standard, 5 um optional), gauge scale (MPa, psi or bar) and thread (PT standard, G or NPT to order). Flow data for the GFR400 is published as curves rather than a single rated figure - 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.

Feeding spray guns and air-assisted applicators at a finishing-line drop, where water and fine particles must be stripped out and the gun supply pressure held steady between operators.
Supplying clean, regulated air to fixture clamps and swing cylinders on a machining cell, where a pressure upset mid-cycle would release a workpiece.
Regulating supply to diverters, pushers and sealing jaws on a packaging conveyor, where consistent actuator pressure keeps timing and seal quality repeatable through the shift.
Size 400 with a G1/2 port sits in the upper half of the GFR range; step up to size 600 or down to 300/200 depending on the flow your line needs - because flow is published as curves, not a single rating, ask us to confirm sizing against your application before ordering. Drain choice matters: this unit has a manual drain, which suits installations where an operator can bleed the bowl on a routine; choose the automatic or differential-pressure drain versions where the unit is inaccessible. The 5 um element (code W) is the right pick when downstream equipment needs cleaner air than the 40 um standard element delivers. The square gauge here reads psi; MPa and bar scales are available. PT is the standard thread and G (BSPP) or NPT are catalogue options to order - specify the thread you need when ordering, and note the bracket is included with this configuration.
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 performance curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your line pressure, downstream pressure target and expected air demand, and we will confirm the sizing from the datasheet curves on request.
The manual drain means the bowl is emptied by hand, which suits units mounted where an operator passes regularly. If the GFR400 will be installed in an inaccessible spot or you want condensate removed without attention, the same family is available with an automatic drain or the differential-pressure drain as the default - specify the drain code you prefer when ordering.
