The AirTAC GFR Filter Regulator GFR400C10AC1W 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 GFR400C10AC1W is an AirTAC G-series filter regulator fitted with the fine 5 um filter element: it removes water and finer particulate from compressed air and holds downstream pressure at your setpoint in a single body. This configuration is the size 400 unit with a 3/8 in PT port, an automatic drain that purges condensate from the polycarbonate bowl, and an external round pressure gauge reading in MPa. With the automatic drain, the regulation range is 0.15-0.9 MPa (20-130 psi); maximum inlet pressure is 1.0 MPa (145 psi) and operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The W suffix selects the 5 um element over the standard 40 um one in the same body. The G-series filter regulator also comes in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options including manual or automatic drains, G (BSPP) or NPT threads, no-bracket (J), no-gauge (N), square gauges with psi or bar scales, and a check-valve (K) variant. Flow is published as performance curves rather than a single rated figure, so ask us and we will confirm the datasheet numbers for your application.

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.

Clean, regulated supply for flow controllers, transducers and small pilot valves on a pneumatic test bench, where the 5 um element screens finer particles than the standard element.
Prep air for HVLP guns in an automotive or woodwork finishing booth - water removed into the auto-drain bowl and finer particulate caught by the 5 um element before the gun.
Regulated air for pick-and-place and small actuation stations on an SMT or electronics line, where the finer element helps protect sensitive pneumatic components.
Pick the W suffix when the equipment downstream needs finer filtration than the standard 40 um element provides - the 5 um element fits the same size 400 body with the same 3/8 in PT port. Step the size (200/300/400/600) to match required flow. Drain: automatic (this code), manual (M), or the default differential-pressure type. Gauge: external round, MPa scale (C1); embedded square gauges and psi/bar scales are available. Thread: PT is the standard, with G (BSPP) and NPT as catalogue options, and the bracket is included (J deletes it). Flow is published as curves, not a single rating - send us your flow and pressure requirement and we will confirm sizing against the application 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 G-series flow as performance curves rather than a single rated figure, so we do not state one here. Give us your required flow and working pressure and we will confirm the datasheet curve data for this model on request.
Choose W (5 um) when downstream equipment - spray guns, instrumentation, precision valves - needs finer particulate removal; keep the 40 um standard element for general cylinder and tool supply. Both fit the same size 400 body with the same port, drain and gauge options.
