The AirTAC GFR400C10F2W AirTAC Filter Regulator 3/8 in PT, 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 GFR400C10F2W 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 3/8 in PT port, a 5 um filter element (the finer of the two published grades), a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element rises, a standard regulator with a 0.15-0.9 MPa (20-130 psi) setting range, and an embedded square gauge reading in psi. A mounting bracket is included.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, MPa, psi or bar gauge scales, and PT, G or NPT threads. Flow figures for this series are published as curves rather than a single rating, 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.

Feeds filtered, regulated air to the tool-clamp and chuck-actuation circuits of a CNC machining centre, where the 5 um element protects the clamping valve stack from water and swarf carried in shop air.
Sits upstream of the cylinders and flap actuators on a carton-sealing machine, holding a steady working pressure so the taping head and box clamps cycle consistently through every shift.
Conditions the air feeding the fill-valve and capper actuators on a bottling line, keeping moisture and fine particulate out of the valve seats while the regulator pins the pressure the filler controls were set around.
Size and port set the capacity envelope: GFR400 takes a 3/8 in port and sits above the 200/300 sizes and below the 600 in the published flow curves, so step up or down according to the air demand of the circuit rather than the port alone. The drain choice matters: differential-pressure (this unit) needs no operator attention but only purges when the element loads up, automatic drains on a cycle, and manual drains suit intermittent-duty installations where someone checks the bowl. Filtration is 40 um standard or 5 um with the W code - this unit is the 5 um version, the right call for directional valves, cylinders and instrumentation that tolerate less particulate. The gauge is the embedded square type; psi scale here, with MPa and bar scales available, and an external round gauge is an option. Thread is PT as standard with G and NPT as orderable options, and a bracket is included.
Because flow for the G-series is published only as curves and not as a single rated figure, we do not quote a number here - 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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a number on the page. Tell us your line pressure, set pressure and air demand, and we will confirm the flow figures from the datasheet for this 3/8 in size-400 unit on request.
The W in the model code selects the 5 um filter grade; without it, GFR units ship with the 40 um standard element. The 5 um grade suits downstream directional valves, cylinders and instrumentation that need finer particulate removal, while 40 um remains the economical choice for general plant air.
