The AirTAC GFR400C10MF1TK 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 AirTAC GFR400C10MF1TK is a size-400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a 3/8 in NPT port, a 40 um standard filter element, a manual drain bowl in polycarbonate, an embedded square pressure gauge scaled in MPa, a built-in reverse/check valve, and a mounting bracket. With manual drainage, the regulation range is 0.05-0.9 MPa (7-130 psi), and maximum inlet pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, optional 5 um filtration (code W), automatic or differential-pressure drainage, alternate gauge scales in psi or bar, and G (BSPP) or NPT threads as order options. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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 air feed to a bench or pneumatic press station, where the check valve holds set pressure if the upstream supply dips and the manual drain is bled at shift start.
Point-of-use conditioning on a packaging line drop, filtering condensed water and pipe scale out of the air before it reaches cylinders and sealing jaws at a stable set pressure.
Conditioned air to a plant air manifold serving gauges and small actuators, with the MPa-scaled square gauge giving operators a local reading of the regulated line pressure.
Size 400 with a 3/8 in port sits in the upper-middle of the GFR range; step up to size 600 or down to size 300 depending on the flow your line needs - we can confirm against the published flow curves before you order. Drainage here is manual, so plan a routine bleed of the bowl; automatic or differential-pressure drainage is available on other variants if you prefer not to rely on operator attention. The 40 um element is the standard grade; specify 5 um (code W) where finer particulate removal matters. The embedded square gauge reads in MPa; psi or bar scales and an external round gauge are order options. Thread is NPT on this unit, with G (BSPP) available to order; PT is the catalogue standard. A mounting bracket is included.
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 number, so we do not quote a figure that could mislead your sizing. Tell us your line pressure and the flow your application needs, and we will confirm the sizing against the datasheet curves on request before you order.
The M in the code sets manual drainage: collected water is released by operating the drain by hand, so the bowl should be bled as part of a routine check. If you would rather not rely on operator attention, GFR variants with automatic or differential-pressure drainage are available - ask us to quote the equivalent configuration.
