The AirTAC GFR400C10C2W AirTAC Filter Regulator PT3/8 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 GFR400C10C2W is an AirTAC GFR400 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. It filters compressed air down to 5 um (the fine W grade, versus the standard 40 um element) while regulating downstream pressure across 0.15-0.9 MPa (20-130 psi). This configuration is PT3/8 ported with PT thread as standard, uses the differential-pressure drain, and is fitted with a round external gauge reading in psi. Maximum inlet pressure is 1.0 MPa (145 psi), working temperature is -5 to 70 C (non-freezing), and the bowl on this 400 size is polycarbonate. A mounting bracket is included.
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, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, embedded square or external round gauges with MPa, psi or bar scales, and PT, G or NPT thread options. Flow is published as curves rather than a single rating, so we confirm datasheet figures 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 air preparation for the clamping fixtures and tool-change cylinders on a machining centre: the 5 um element protects fine valve seats while the regulator holds a steady set pressure to the actuators.
A filter regulator at each work-station drop on an assembly line, giving operators clean air and a locally adjustable pressure for air tools and small pneumatic presses fed from a 3/8 in branch.
Conditioning the supply to sorting gates, pushers and stopper cylinders on a packaging conveyor, where the differential-pressure drain keeps condensate off the cylinders without daily manual blowdown.
Size up through the GFR range (200, 300, 400, 600) so the port step matches the air demand of the circuit; this unit sits at the 400 size with a 3/8 in PT port. Choose the drain to suit access: differential-pressure (as fitted here) drains automatically under flow, automatic suits intermittent-flow lines, and manual suits attended installations - note the manual-drain version widens the regulation range down to 0.05 MPa. The 5 um W element fitted here is the right pick where finer air quality matters; the standard grade is 40 um. Gauge scale (MPa, psi or bar - psi here) and thread (PT standard, G or NPT to order) are decodable choices.
Flow for this family is published as curves, not a single rated figure, so ask us to confirm sizing against your application and the datasheet 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 this family as curves rather than a single rated figure, so we do not quote a number. Tell us your application and required flow, and we will confirm the sizing against the datasheet on request before you order.
The W in the code GFR400C10C2W selects the optional 5 um filtration grade; the catalogue standard is 40 um. Choose 5 um where downstream valves, cylinders or instruments need finer protection, and note the differential-pressure drain on this configuration discharges collected condensate automatically under flow.
