The AirTAC GFR400C10AF2TK AirTAC Filter Regulator NPT3/8 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 GFR400C10AF2TK is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This configuration carries a 3/8 in NPT port, 40 um standard filtration, an automatic drain, and a standard regulator adjustable from 0.15-0.9 MPa (20-130 psi). A square psi gauge is fitted, a reverse/check valve is included, and the mounting bracket comes with the unit. The polycarbonate bowl suits non-freezing compressed air from -5 to 70 C, with a maximum inlet pressure of 1.0 MPa (145 psi).
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, and options include 5 um (W) filtration, manual or differential-pressure drains, MPa/psi/bar gauge scales, and G or NPT threads in place of the PT standard. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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 clean, regulated air to a machining center's pneumatic clamps and tool-change actuators, with the automatic drain keeping condensate out of the spindle-area circuit.
Holding steady pressure to carton-sealer and case-packer cylinders so jaw timing stays consistent through the shift, while the 40 um element stops pipe scale reaching the valves.
Regulating supply air to a small pneumatic press or riveting station, with the check valve holding downstream pressure when the main supply is vented.
Pick the size by the port and flow step: 200, 300, 400 and 600 move up through 1/8 in to 1 in ports, so step up a size when the line draws more air - we can check the flow curve against your demand before you order. Drain type is a real choice: automatic (as fitted here) clears condensate without attention, manual needs an operator, and differential-pressure drain is the catalogue default. Filtration is 40 um standard or 5 um with code W; gauge scales are MPa, psi or bar; threads can be ordered as PT (standard), G or NPT; and a bracket can be included or omitted (code J).
Flow for this family is published as curves, not a single rating, so ask us to confirm sizing against 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, not a single rated figure, so we do not quote one number. Send us your air demand and port size and we will confirm sizing against the datasheet before you order.
This configuration carries code A, the automatic drain, which removes collected condensate without operator attention. The catalogue alternatives are manual drain (code M) and the differential-pressure drain, which is the default when no drain code is given. All three are available across the GFR sizes.
