The AirTAC GFR40010JF2WT 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 GFR40010JF2WT is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This unit is sized 400 with a 3/8 in NPT port, carries the fine 5 um filter element (code W instead of the standard 40 um), drains condensate by differential pressure, and is fitted with an embedded square gauge scaled in psi. The regulation range is 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl gives a clear view of condensate level, and this configuration is supplied without a mounting bracket.
This is a genuine AirTAC part. The GFR filter-regulator family is available in sizes 200, 300, 400 and 600 with a choice of ports, threads (PT standard; G and NPT as order options), drain types (differential-pressure, automatic or manual), filter grades (40 um standard, 5 um optional) and gauge scales (MPa, psi or bar). Because published flow data appears as curves rather than a single rated figure, we confirm the exact flow and datasheet figures for your application 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.

Feeds filtered, pressure-regulated air to the tool-clamp and actuator circuits of a CNC machining centre, where the 5 um element protects precision valves from particulate carryover.
Serves as the conditioning point for the pneumatic cylinders on a carton-sealing or case-packing conveyor line, giving operators a local psi gauge to set and verify line pressure.
Installed at the drop feeding a small pneumatic press or clamping fixture, combining water and particle removal with a stable regulated setting for repeatable clamping force.
Start by matching the size and port to the air demand of the circuit: the 400 size with a 3/8 in NPT port sits in the middle of the GFR range, and the next step up or down in size changes both the port and the flow capacity shown in the catalogue curves. Choose the filter grade to suit the equipment downstream: this unit carries the 5 um element (code W) for finer protection, while the standard grade is 40 um. Drain type is a real choice: differential-pressure drain (this unit) discharges as flow conditions warrant, automatic drain suits unattended installations, and manual drain suits supervised points. Gauge scale (MPa, psi or bar) should match the instruments your team reads, and the thread must match your piping: PT is the standard, with G (BSPP) and NPT as order options. A mounting bracket is optional (this configuration has none). 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 GFR400 series as curves rather than a single rated figure, so we do not quote one number. Tell us your application and required flow, and we will confirm the sizing against the datasheet curves on request before you order.
The W in the model code specifies the optional 5 um filter grade, which gives finer filtration than the 40 um standard element. It is the right choice when downstream valves, cylinders or instruments need cleaner air; if your line does not require fine filtration, the standard 40 um grade is available in the same series.
