The AirTAC GFR400C10C1WT AirTAC Filter Regulator 3/8 in NPT 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 GFR400C10C1WT 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 the 400 size with a 3/8 in NPT port, the 5 um filtration grade (the finer of the two catalogue options), a differential-pressure drain, and a round pressure gauge scaled in MPa. A mounting bracket is included.
This is a genuine AirTAC part. The GFR400 series is one of four sizes (200/300/400/600), with port options, drain types, filter grades, gauge styles and scales, and G or NPT thread variants available to order. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm the figures from the datasheet 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.

Feeding filtered, regulated air to a bank of directional control valves on an automated line, where the 5 um element helps keep spool and seal contamination down and the MPa gauge gives a local set-pressure check.
Supplying cylinders and grippers on a packaging conveyor, with the regulator set to the pressure the machine builder specifies and the differential-pressure drain keeping the bowl clear without operator attention.
A point-of-use filter regulator at a factory air drop serving air tools, blow-off stations or small machines, holding a steady downstream pressure as main line pressure fluctuates through the shift.
The 400 size with a 3/8 in NPT port is the step up from the 200/300 sizes; match the size to your air demand and we will confirm the flow curve against your application before you order. The 5 um element (code W) is the finer choice over the standard 40 um where downstream valves and cylinders need cleaner air, and the differential-pressure drain bleeds the bowl automatically as air passes, with no daily manual draining. The round MPa gauge is fitted on this unit; psi and bar scales and an embedded square gauge are the other catalogue options. G (BSPP) and NPT threads are order options alongside the PT standard, and the included bracket makes panel or wall mounting straightforward.
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, not a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the relevant flow figures from the datasheet before you order.
The W code sets the 5 um filtration grade, the finer option over the standard 40 um, for cleaner air to sensitive valves and cylinders. The drain is the differential-pressure type: it discharges collected condensate automatically as air flows, so no manual draining is needed in normal operation. Maximum inlet pressure is 1.0 MPa (145 psi) and the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi).
