The AirTAC GFR400C10JF2WT AirTAC Filter Regulator NPT3/8 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 GFR400C10JF2WT is an AirTAC GFR400 filter regulator: filtration and pressure regulation combined in one body. It removes water and particulate from compressed air through a 5 um element (the fine grade, code W, versus the 40 um standard) and holds downstream pressure within a 0.15-0.9 MPa (20-130 psi) adjustment range. This configuration has a 3/8 in NPT port, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, an embedded square gauge reading in psi, a standard (not low-pressure) regulator, and no reverse/check valve fitted. The polycarbonate bowl suits non-freezing compressed-air service from -5 to 70 C, with maximum inlet pressure of 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options include manual or automatic drains, the 40 um or 5 um element, gauges with MPa, psi or bar scales, G (BSPP) or NPT threads in place of the PT standard, a bracket, and a reverse/check valve. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures on request.

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 a pneumatic press cylinder, the GFR400C10JF2WT strips water and fine particulate before the valve stack and holds a steady set pressure so the press stroke repeats consistently shift after shift. The psi square gauge lets the setter read the setting directly.
On a lab test bench supplied from a shop-air ring main, the 5 um element protects sensitive instrumentation and pneumatic controls from fine particles, while the regulator gives the technician an independent, adjustable supply pressure at the bench.
Supplying the pick-and-place and clamp cylinders on a packaging conveyor line, the unit conditions the air before the directional valves and keeps actuation pressure stable as multiple machines draw from the same header. The differential-pressure drain handles condensate during normal production flow.
Size and port set the capacity: this unit is size 400 with a 3/8 in NPT port, one step up from size 300 (1/4 in) and one below size 600 (3/4 in), so step up or down as your air demand requires. Drain choice matters: the differential-pressure drain fitted here needs a minimum flow to purge, so pick an automatic drain for low or intermittent flow, or a manual drain where an operator drains the bowl routinely. The 5 um element fitted here is the finer option versus the 40 um standard - choose 5 um where downstream equipment is sensitive to fine particulate. Gauge scale (MPa, psi or bar - psi here) and thread (PT standard, G or NPT to order) are decodable choices, and the bracket is optional. 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 GFR series as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your application and operating pressure and we will confirm the sizing from the datasheet on request before you order.
The W in the code GFR400C10JF2WT selects the 5 um filter grade, the finer of the two catalogue options (40 um is the standard). Choose 5 um where downstream valves, instruments or processes are sensitive to fine particulate; the 40 um grade suits general shop-air protection. Both grades are available across the GFR sizes.
