The AirTAC GFR400C10C2WG 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 AirTAC GFR400C10C2WG is a size-400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration has a G3/8 (BSPP) port, a 5 um filter element (the finer W grade, versus the 40 um standard), a differential-pressure drain that bleeds condensate automatically whenever the pressure drop across the element rises, and a round pressure gauge with a psi scale. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl keeps the condensate visible, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600 with a matching port range, and with choices of drain type, filter grade, gauge style and scale, thread (PT standard; G and NPT are order options), and low-pressure or standard regulator type. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Point-of-use preparation for the machine tool's pneumatic clamps and tool-change circuits: the 5 um element protects fine spool valves from particulate and water while the regulator holds a steady setting for repeatable clamping.
Feeding the air cylinders that divert cartons on a bottling or packaging conveyor. The differential-pressure drain keeps condensate out of the valve manifold without daily manual blowing-down, and the psi gauge lets line staff verify the set point at a glance.
Mounted at the drop from the plant air main to a small pneumatic press or forming station: the filter-regulator combination cleans the incoming air and sets the working pressure the tool was designed for, with the included bracket fixing the unit to the machine frame.
Step up or down through the GFR sizes (200/300/400/600) so the port and body match the flow your line needs; this size-400 unit carries a 3/8 in port. Choose the 5 um element (this code, W) when downstream valves, cylinders or instruments need finer air than the 40 um standard grade. Drain choice matters: differential-pressure (this configuration) needs no attention between pressure swings, automatic drains continuously, and manual drain suits supervised points. Gauge options are the embedded square type or an external round gauge, with MPa, psi or bar scales - this unit carries a round psi gauge. Thread is G (BSPP) here; PT is the standard and G/NPT are order options, and a bracket is included.
Because flow is published as curves rather than a single rating, we do not quote one number here. Send us your application details and we will confirm the datasheet and sizing 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 one number here. Tell us your application and we will confirm the datasheet and check the sizing against your required flow on request.
W is the finer 5 um filter element, chosen over the 40 um standard grade when downstream equipment needs cleaner air. C2 in the code specifies the external round gauge with a psi scale; the embedded square gauge with MPa, psi or bar scales is also available across the range.
