The AirTAC GFR40010JC2WT AirTAC Filter Regulator NPT3/8 5 um is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/8" 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 GFR40010JC2WT is an AirTAC GFR400 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This unit is built in size 400 with a 3/8 in NPT port, carries a 5 um filter element (code W) for finer filtration than the standard 40 um grade, and drains condensate by differential pressure, so the bowl self-drains as flow passes through it. The fitted round gauge reads in psi, the regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and maximum inlet pressure is 1.0 MPa (145 psi). The polycarbonate bowl suits the -5 to 70 C (non-freezing) operating range, and this configuration comes without a mounting bracket.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, gauge style and scale options, and PT, G or NPT threads. Flow figures for the series are published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application before you order.

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, pressure-stabilised air to clamping and pressing cylinders on a production line, where the 5 um element protects valve spools from particulate and the regulator holds a consistent clamp force setpoint.
Supplying filtered and regulated air to diverters, stoppers and carton-forming cylinders on a packaging conveyor, with the differential-pressure drain clearing condensate through continuous-shift running.
A wall-drop filter regulator at a maintenance bench, giving technicians dry, fine-filtered air at a set pressure for air tools, blow-off guns and small test rigs, with the psi gauge read at a glance.
Size 400 with a 3/8 in NPT port is the mid-to-large step in the GFR range; step up or down (200/300/400/600) to match the flow your line needs, and confirm the fit against the published flow curves with us before ordering. The 5 um element (code W) is the right choice when downstream valves, cylinders or instruments need finer air than the standard 40 um grade. The differential-pressure drain works automatically as air flows through, so no daily manual draining is needed; if the unit will sit at low or intermittent flow, ask about automatic or manual drain versions. The round psi gauge suits US practice; square gauges and MPa or bar scales are also available. NPT is the thread fitted here - PT is standard and G (BSPP) can be ordered. A mounting bracket can be added if this no-bracket configuration needs panel fixing.
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 GFR flow as curves rather than a single rated figure, so we do not quote a rated l/min or SCFM number. Tell us your inlet pressure, set pressure and the flow your application needs, and we will confirm the datasheet curve figures and check the sizing for you before you order.
The standard GFR element is 40 um, which suits general plant air. This unit carries the 5 um option, which removes finer particulate and is the better choice upstream of precision valves, air bearings, spray equipment or instrumentation. The finer grade is a decodable order option - if your line only needs general protection, the 40 um version of the same size is available.
