The AirTAC AirTAC GFR400C10F2WT Filter Regulator NPT 3/8 in 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 GFR400C10F2WT is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body with one drain bowl. This configuration is a size-400 unit with a 3/8 in NPT port, a 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain, and a standard regulator adjustable from 0.15 to 0.9 MPa (20 to 130 psi). An embedded square gauge reading in psi is fitted, the maximum inlet pressure is 1.0 MPa (145 psi), the operating temperature range is -5 to 70 C (non-freezing), the bowl on this size is polycarbonate (PC), and 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 to 1 in, and can be ordered with manual or automatic drains instead of the differential-pressure drain, a 40 um standard element instead of 5 um, gauge scales in MPa, psi or bar, PT (standard), G (BSPP) or NPT threads, and with or without a bracket. Flow for this series is published as curves rather than a single figure, so ask us to confirm the datasheet and sizing for your application before ordering.

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 clean, regulated air to the tool-clamp and pallet-clamping circuits of a CNC machining centre. The 5 um element strips water and particles before the directional valves, while the regulator holds the clamping circuit at its set pressure and the psi gauge lets setters verify it at a glance.
Supplying regulated air to the pusher and divert cylinders on a carton-sealing conveyor line. The combined filter-regulator body saves a panel slot, and the differential-pressure drain bleeds collected condensate out of the bowl as air flows through, without a routine manual drain stop.
Point-of-use regulation at an assembly-plant air drop that feeds hand tools and small actuators. The unit filters the drop supply down to 5 um, holds the branch at the pressure the station was set up for, and the embedded square psi gauge gives operators a permanent readout of the working line pressure.
Choose the size and port by the air consumption of the downstream circuit: this unit is size 400 with a 3/8 in NPT port, above the size-300 class and below size 600. The 5 um element (code W) suits circuits with sensitive valves, cylinders or instrumentation, while the 40 um standard element is the economical choice for general service. Drain options are differential-pressure (fitted here), automatic, or manual; the differential-pressure and automatic drains correspond to the 0.15-0.9 MPa (20-130 psi) adjustment range, while a manual-drain variant widens it to 0.05-0.9 MPa (7-130 psi).
The gauge scale on this unit is psi; MPa and bar scales are order options, and an external round gauge can be fitted instead of the embedded square gauge. Thread is NPT here; PT is the standard thread and G (BSPP) is also a catalogue option. A mounting bracket is included. Flow for the GFR series is published as curves, not a single rating, so send us your flow requirement 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 rather than a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm the sizing against the datasheet on request.
The W code fits the finer 5 um element, which suits circuits with sensitive valves, instrumentation or precision actuators; the 40 um element is the standard choice for general service. Both grades are catalogue options across the GFR filter-regulator range, and the choice does not change the 3/8 in NPT port or the 0.15-0.9 MPa (20-130 psi) adjustment range of this differential-pressure-drain unit.
