The AirTAC GFR400C10JF2WG AirTAC Filter Regulator G3/8, 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 GFR400C10JF2WG is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in a single body. This configuration is built around a G3/8 (3/8 in) port with G (BSPP) thread, a 5 um filter element for finer filtration than the standard 40 um grade, and a differential-pressure drain that bleeds collected condensate automatically as the pressure differential across the element builds. Output pressure is set anywhere in the 0.15-0.9 MPa (20-130 psi) range with the standard regulator and read on the fitted embedded square gauge scaled in psi. This version carries a metal bowl and is supplied without a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options including automatic or manual drains, a 40 um standard or 5 um fine element, gauges in MPa, psi or bar scales, an optional reverse/check valve, and PT, G or NPT threads. We confirm flow and other datasheet figures on request, because AirTAC publishes flow as curves rather than a single rated number.

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 filtered, regulated air to pneumatic clamps and tool-change cylinders on a machining centre, holding a steady set pressure through every clamp-cut-release cycle.
Supplying clean, regulated air to carton-forming and sealing cylinders on a packaging conveyor, where the 5 um element helps protect sensitive directional valves from fine contamination.
A filter regulator at branch take-offs on a factory air main, giving each work cell its own locally set downstream pressure and its own condensate handling.
Choose the size by port and flow: size 400 sits above 300 and below 600 in both port and flow capacity, so step up or down if your line needs more or less air. This unit is already set for G3/8 with G thread; PT is the standard thread and NPT can be ordered instead if your piping is imperial. The 5 um element here is the finer option - pick 40 um where coarse protection is enough. Drain choice matters: differential-pressure (this unit) needs no routine attention, automatic drains continuously, and manual suits dry, low-condensate installations. Gauge scale (MPa, psi or bar) and bracket are also selectable. Because AirTAC publishes flow as curves rather than a single rating, ask us to confirm sizing against your application before ordering.
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 rather than a single rated figure, so we do not quote a number. Send us your required flow and working pressure and we will confirm sizing from the datasheet on request.
The W code on this model orders the optional 5 um grade, which captures finer particles than the standard 40 um element - useful upstream of precision valves and other sensitive components. Both grades are available across the GFR range if you want to standardise differently.
