The AirTAC GFR400C10MC3T 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 GFR400C10MC3T is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 400 unit carries a 3/8 in NPT port, a 40 um standard filter element, and a manual drain, so condensate is released only when an operator opens the drain. It is fitted with an external round gauge reading in bar, and the regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi). Maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl suits general indoor compressed-air service, and a mounting bracket is included.
This is a genuine AirTAC part from the GFR filter-regulator line, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, thread choices of PT (standard), G and NPT, drain types (differential-pressure, automatic or manual), a 5 um optional filter grade (code W), and gauge or no-gauge variants. Flow for this series is published as curves rather than a single rated figure, so contact us and we will confirm the datasheet and sizing figures for your application 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.

Installed on the air feed to a workshop pneumatic press, this unit filters water and swarf from the shop supply and holds a steady regulated pressure so the press cylinder cycles consistently through the shift.
Mounted at the drop of a packaging-machine air ring main, it cleans the supply feeding gripper and clamp cylinders and lets the line setter set the working pressure with the round bar gauge.
Fitted inside a machine builder's pneumatic cabinet ahead of direction valves and air cylinders, the filter regulator protects downstream components from condensate and particulate while providing an adjustable set pressure.
Size 400 with a 3/8 in NPT port sits in the middle of the GFR range: step up or down (200/300/400/600) according to the pipe size and flow demand of the line. This unit has a manual drain, which suits installations where an operator can bleed condensate regularly; choose automatic or differential-pressure drain codes where the unit is hard to reach. The 40 um element is the standard grade; specify the W code for 5 um when finer particulate removal is needed. The fitted round gauge reads in bar; square embedded gauges and MPa/psi scales are available as alternatives. NPT is the thread on this code; PT is the catalogue standard and G is also orderable. A mounting bracket is included.
Because flow for the GFR series is published as curves and not as a single rated number, we do not quote a rated flow figure here. Ask us to confirm the datasheet and check the sizing of this GFR400C10MC3T against your application 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 the GFR series as curves, not as a single rated figure, so we do not state a rated flow, Cv or SCFM number. Contact us and we will confirm the datasheet and check the flow of this size 400, 3/8 in unit against your application on request.
This unit has a manual drain, so condensate collected in the polycarbonate bowl must be released by opening the drain by hand at suitable intervals. With a manual drain the regulator adjustment range is 0.05-0.9 MPa (7-130 psi). If the unit will be mounted where regular draining is impractical, ask us about automatic or differential-pressure drain variants.
