The AirTAC GFR Filter Regulator GFR400C10MF1K 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 GFR400C10MF1K is an AirTAC G-series filter regulator with a built-in reverse (check) valve: water and particulate filtration plus pressure regulation in one body, with backflow through the unit prevented. This configuration is the 400 size with a 3/8 in PT port, a 40 um standard filter element, and a manual drain you open by hand to empty the bowl. An embedded square gauge on an MPa scale shows the regulated pressure, the adjustment range is 0.05-0.9 MPa (7-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the working range is -5 to 70 C, non-freezing. The 400-size bowl is polycarbonate (PC).
This is a genuine AirTAC part from the G-series 200/300/400/600 size range, with catalogue options across port sizes, thread types (PT standard, with G and NPT as orderable variants), drain types, filter grades, gauges and the K check-valve code. Series flow is published as performance curves rather than a single rated figure, so we confirm sizing and full datasheet figures on request.

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.

Filter and regulate the air feeding the pick-and-place cylinders of an assembly cell, with the check valve holding the downstream setpoint if the main supply dips.
Feed the divertor and stopper cylinders along a packaging conveyor with filtered, regulated air, protecting the actuators from water and debris in the shop line.
Set a stable, filtered supply for blow-off nozzle stations at a workbench, adjusting pressure at the MPa gauge and draining the bowl by hand during clean-down.
Size the unit on the 200/300/400/600 ladder and matching port; this 400 body takes a 3/8 in PT port. The K code is the decodable difference here: it fits a reverse/check valve, so specify it wherever downstream pressure must be held if the upstream supply is interrupted. Drain is manual (M); automatic and differential-pressure versions exist, and manual drain gives the wider 0.05-0.9 MPa (7-130 psi) adjustment range. Element grade is 40 um standard, or 5 um with the W code. The square gauge reads in MPa, with psi/bar scales and an external round gauge as options. Thread is PT standard, G (BSPP) and NPT orderable; J omits the bracket. Flow is published as curves, not a single rating - ask us to confirm sizing 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 G-series capacity as performance curves rather than one rated-flow number, so we do not state a figure here. Share your application's pressure and demand and we will confirm sizing and the curve figures from the datasheet on request.
K specifies a built-in reverse (check) valve. It blocks backflow through the unit, helping hold the regulated downstream pressure when the upstream supply drops or is shut off. The same body is available without the valve by dropping the K from the code.
