The AirTAC GFR400C10MJF3TK 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 GFR400C10MJF3TK is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has 3/8 in NPT ports, a manual-drain PC (polycarbonate) bowl, a 40 um standard filter element, an embedded square gauge reading in bar, a reverse/check valve fitted, and no mounting bracket. With manual drainage the regulation range is 0.05-0.9 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 spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options include automatic or differential-pressure drains, a 5 um element (code W), gauge scales in MPa or psi, G (BSPP) or NPT threads, and a mounting bracket. Flow is published as curves rather than a single rated figure, 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.

Point-of-use conditioning for the pneumatic circuits on a CNC machining centre: clean, regulated air to the tool changer, clamps and air-powered ancillaries on the machine.
Feeding regulated air to the cylinders and diverters on a carton packaging line, where a stable set pressure keeps sealing and sorting motions repeatable shift after shift.
Installed at a drop from the factory ring main to condition air before it reaches local valves and actuators, with the fitted check valve holding downstream pressure if supply dips.
Size and port set the air capacity: this unit is size 400 with 3/8 in NPT ports, and the family steps from size 200 to 600 as flow demand grows. Drain choice matters: manual drainage (this unit, carrying the wider 0.05-0.9 MPa / 7-130 psi regulation range) versus automatic or differential-pressure drainage. Filter grade is 40 um standard; choose 5 um (code W) for finer protection. The embedded square gauge here reads in bar; MPa and psi scales and an external round gauge are options. On thread, PT is the AirTAC standard with G (BSPP) and NPT as order options - this unit is NPT. A bracket is optional and this configuration is supplied without one. Flow is published as curves, not a single rating, so ask us to confirm sizing 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 GFR400 as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and other datasheet figures on request before you order.
The M in the code specifies a manual drain: condensate collected in the PC bowl is released by hand, and this drain type carries the 0.05-0.9 MPa (7-130 psi) regulation range. Automatic (code A) and differential-pressure (blank) drains are available on the GFR400 if you would rather not drain the bowl manually.
