The AirTAC GFR400C10MJNWT AirTAC Filter Regulator NPT 3/8 in, 5 um 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 GFR400C10MJNWT is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single 400-size body. This configuration is threaded NPT 3/8 in, carries a 5 um filter element, drains by hand through its manual drain, and has no gauge, no reverse valve and no mounting bracket fitted. The polycarbonate bowl suits this 400 size (only size 600 uses an aluminium alloy bowl), maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator covers 0.05-0.9 MPa (7-130 psi) with manual drain, and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the GFR range, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, PT as the standard thread and G or NPT as order options, plus automatic, manual or differential-pressure drains and 40 um or 5 um elements. AirTAC publishes flow as curves rather than a single rating, so ask us to confirm the 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.

Filter and regulate the shop-air drop feeding a CNC machining center's pneumatic clamps and chip-clearing jets, with the 5 um element guarding fine spool valves.
Set a stable pressure for carton-sealing and case-packing cylinders on a packaging conveyor, where the manual drain suits a supervised daily-check routine.
Condition the air feeding spray guns in a finish booth, using the 5 um element and steady regulated pressure as part of a clean, dry finish-air setup.
Step through sizes 200, 300, 400 and 600 to match the port and flow your line needs; this 400-size unit takes a 3/8 in NPT connection. Choose the drain to suit access: manual as fitted here (which also widens the regulation range to 0.05-0.9 MPa), automatic for hands-off condensate removal, or differential-pressure as the range default. Pick the 40 um standard element for general air or the 5 um W element for finer protection downstream. Gauge type and scale (MPa, psi or bar), reverse valve and bracket are decodable choices across the range; this unit has none of them fitted. Thread is NPT here, with PT as the standard and G (BSPP) available to order. Because AirTAC publishes flow only as curves, not a single rating, ask us to confirm sizing against your application 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 GFR400 as curves rather than a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the datasheet flow curve and sizing on request before you order.
This unit drains collected condensate by hand, which suits installations checked on a regular maintenance round. If the point is unattended, the GFR400 range also offers automatic and differential-pressure drains. Note the regulation range differs by drain type: 0.05-0.9 MPa (7-130 psi) with the manual drain fitted here.
