The AirTAC GFR400C10MJF2WK AirTAC Filter Regulator 3/8 PT 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 GFR400C10MJF2WK is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is a 3/8 in PT port unit with a manual drain bowl, a 5 um filter element (the finer of the two published grades), an embedded square gauge reading in psi, and a built-in reverse/check valve that helps hold downstream pressure if the upstream supply drops. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range for a manual-drain unit is 0.05-0.9 MPa (7-130 psi), and the operating temperature range is -5 to 70 C, non-freezing. The bowl on size 400 units is polycarbonate, and no mounting bracket is included in this configuration.
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 each size can be ordered with manual, automatic or differential-pressure draining, a 40 um standard or 5 um fine element, a square gauge in MPa, psi or bar scale (an external round gauge is optional), with or without a reverse/check valve, and in PT, G (BSPP) or NPT thread. Flow for this family is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures 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.

Feeding filtered, regulated air to tool-clamp cylinders and pallet-actuator circuits on a CNC machining center, where the 5 um element protects precision directional valves and the regulator holds a set clamp pressure.
Supplying air to grip, lift and divert cylinders on a bottling or packaging line, with the manual-drain bowl serviced during scheduled changeovers and the check valve holding the circuit if plant supply dips.
Regulating air to pick-and-place grippers and clamp modules at a robotic assembly station, where stable downstream pressure keeps repeat cycles consistent and the psi gauge lets technicians verify the setpoint at a glance.
Size 400 with a 3/8 in PT port sits in the upper-middle of the GFR range; step between sizes 200, 300, 400 and 600 to match the flow your line needs, since port size tracks flow capacity. Drain choice matters: this unit drains manually, which suits installations where an operator checks the bowl routinely and which carries the widest 0.05-0.9 MPa (7-130 psi) regulation range; automatic or differential-pressure draining suits unattended duty but regulates 0.15-0.9 MPa (20-130 psi). The fitted 5 um element (code W) is the finer grade for sensitive downstream equipment; 40 um is the standard alternative. The embedded square gauge reads psi; MPa and bar scales are alternatives. PT is the standard thread, with G (BSPP) and NPT as order options, and a mounting bracket is available if you need one. Flow is published as curves, not a single rating - 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 GFR family as curves rather than a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm from the datasheet whether this size 400, 3/8 in PT unit suits your application before you order.
A manual drain suits attended installations where an operator can bleed the bowl during routine checks, and it carries the widest regulation range of 0.05-0.9 MPa (7-130 psi). If the unit will run unattended, automatic or differential-pressure draining is available in the same family, with a 0.15-0.9 MPa (20-130 psi) range.
