The AirTAC GFR40010JC1WT AirTAC Filter Regulator NPT3/8 5um 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 GFR40010JC1WT is an AirTAC GFR400 filter regulator: a single body that removes water and particulate from compressed air and sets downstream pressure, in one 400-size unit with NPT3/8 (3/8 in) ports. This configuration carries the 5 um filter element (code W) for finer filtration than the standard 40 um grade, a differential-pressure drain that bleeds collected condensate automatically whenever the pressure drop across the element rises, and a round pressure gauge with an MPa scale so the outlet setting can be read at a glance. It is a filter regulator only - it does not lubricate the air; add a separate lubricator if oil mist is needed downstream.
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600 with a choice of port, thread (PT standard, G and NPT as order options), drain type, filter grade and gauge, with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing). Flow is published 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.

Feeding clean, pressure-set air to the tool-change clamps and pneumatic actuators on a CNC machining centre, where the 5 um element protects spool valves from fine particulate and the regulator holds a steady clamp pressure.
Conditioning the air that drives diverter gates, pushers and bag-seal cylinders on a packaging conveyor line, with the differential-pressure drain clearing condensate as the element loads through multi-shift running.
Supplying filtered, regulated air to sample-handling actuators and purge lines on a laboratory automation skid, where the 5 um grade and the MPa round gauge give the operator a visible, repeatable setting.
Step through the decodable choices in order. Size 400 with 3/8 in ports sits in the middle of the GFR range - step up to 600 or down to 300/200 according to the flow your line needs, and confirm that flow against the published curves with us rather than assuming a single rated figure. The 5 um element (this unit, code W) suits instruments, valves and actuators that tolerate less particulate than the 40 um standard; note the finer element loads faster, which matters for drain choice. The differential-pressure drain here discharges condensate automatically as the element loads - choose a manual-drain variant only where you want drain events tied to operator rounds, or an automatic drain for continuous unattended duty. The regulator sets 0.15-0.9 MPa (20-130 psi) on this standard type. This unit has a round MPa-scale gauge (the embedded square gauge is the standard alternative, with psi and bar scales available), no reverse/check valve, and no mounting bracket. Thread is NPT here; PT is the standard thread and G is the other order option.
Because flow is published as curves and not a single rating, send us your application's flow and pressure requirements 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 flow for the GFR400 series as curves, not as a single rated number, so there is no one l/min or SCFM figure we can honestly quote. Send us your required flow and working pressure and we will confirm the sizing from the datasheet before you order.
The W code in GFR40010JC1WT selects the optional 5 um filter grade, which removes finer particulate than the 40 um standard - useful for precision valves, instruments and actuators. The trade-off is that the finer element loads faster, which is why this unit pairs it with a differential-pressure drain that discharges condensate automatically as the pressure drop builds.
