The AirTAC GFR400C10MC1TK AirTAC Filter Regulator NPT 3/8 in 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 GFR400C10MC1TK is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration has a 3/8 in NPT port, a manual drain bowl in polycarbonate (PC), a standard 40 um filter element, a fitted reverse/check valve, an included mounting bracket, and a round MPa pressure gauge (an embedded square gauge is the standard fitting, with an external round gauge available as the option on this unit). The regulator adjusts from 0.05 to 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. The GFR family is published in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and with choices of drain type, 40 um or 5 um (W) filtration, gauge type and scale, thread (PT standard; G and NPT to order), bracket and reverse valve. Flow is published as curves rather than a single rating, so ask us and we will confirm the flow and datasheet 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.

Feeding clean, regulated air to the cylinders and actuators on a carton-forming and sealing line, with the manual drain serviced during shift changeovers.
Regulating supply pressure to pop-up diverters and stop gates on a distribution conveyor, with the check valve holding the downstream circuit if supply drops.
Conditioning and setting a stable pressure at a test-bench manifold where instruments and air cylinders need filtered air at a fixed setpoint.
Size 400 with a 3/8 in NPT port suits lines where the required flow sits above the 300 frame; step up or down through 200/300/400/600 to match your port and curve. The manual drain on this unit means an operator opens the bowl drain at intervals - choose the automatic (A) or differential-pressure (blank) drain instead if the unit is hard to reach. The 40 um element is the standard grade; specify W for 5 um where finer particulate removal is needed. The fitted round gauge reads in MPa (scales in psi or bar are order options), and the K code means a reverse/check valve is fitted to hold downstream pressure. Thread here is NPT; PT is the catalogue standard with G (BSPP) available to order, and the mounting bracket is included.
Because flow is published as curves and not as 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 G-series flow as curves, not as a single rated number, so we do not quote a l/min, m3/h or SCFM figure. Tell us your application and we will confirm the flow and full datasheet figures for this unit on request.
The M code means the bowl drain is opened by hand at intervals to remove collected condensate - simple and reliable where the unit is accessible. If the unit will be mounted where it cannot easily be reached, order the same GFR400 size with an automatic (A) or differential-pressure (blank) drain instead.
