The AirTAC GFR400C10MF1T 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 GFR400C10MF1T is a filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body, with a drain bowl but no lubricator. This size 400 unit carries a 3/8 in NPT port, a 40 um standard filter element, and a manual drain you open by hand to expel collected condensate. The standard regulator covers 0.05-0.9 MPa (7-130 psi) with this manual-drain configuration, an embedded square gauge reading in MPa is fitted, a mounting bracket is included, and no reverse/check valve is fitted. Maximum working (inlet) pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the GFR400 series. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options include automatic, manual or differential-pressure drains, a 5 um element (code W), gauge scales in MPa, psi or bar, and G (BSPP) or NPT threads in place of the PT standard. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details for your application before ordering.

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.

Filtered, regulated air feeding the clamping fixtures and tool-change cylinders on a machining centre, with the operator setting line pressure at the square gauge and draining the bowl during shift checks.
Conditioning the air that drives conveyor diverters, seal bars and carton-closing cylinders on a packaging line, where the 40 um element keeps debris out of valves and the manual drain is emptied at scheduled stops.
Mounted at a drop leg serving a work cell or assembly station, giving that station its own filtered and regulated supply instead of relying on a single header-wide setting.
Start with the port step: this unit is 3/8 in NPT on the size 400 body, and moving up or down a size changes both the port and the flow capacity of the family. Drain type is a real choice: manual (this unit, and it widens the regulation range to 0.05-0.9 MPa), automatic for hands-off condensate removal, or the differential-pressure default. Filter grade is 40 um standard; choose the W code for 5 um where finer particulate capture matters. Gauge scale is selectable (MPa, psi or bar) and an external round gauge is optional alongside the embedded square gauge. Thread is PT as the standard, with G (BSPP) and NPT as order options; a bracket is included on this unit. Because flow is published as curves rather than a single rated figure, send us your application details and we will confirm sizing against the datasheet before you order.
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 l/min, m3/h or SCFM figure. Send us your application details and we will confirm the flow and full datasheet figures for this 3/8 in NPT, size 400 unit on request.
The M in the code selects a manual drain: you open it by hand to expel collected water, which suits installations drained at regular intervals. It also gives a wider regulation range of 0.05-0.9 MPa (7-130 psi), compared with 0.15-0.9 MPa (20-130 psi) for automatic or differential-pressure drain versions.
