The AirTAC GFR400C15JF2WK AirTAC Filter Regulator PT1/2, 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 GFR400C15JF2WK is a size-400 filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This configuration is a 1/2 in PT-threaded unit with a fine 5 um filter element (the 40 um standard element is also available in the series), a differential-pressure drain on the bowl, an embedded square gauge reading in psi, and a reverse/check valve fitted so downstream pressure is held if the upstream supply drops. The polycarbonate bowl suits this size, and maximum working (inlet) pressure is 1.0 MPa (145 psi) with an operating temperature range of -5 to 70 C, non-freezing. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi). No mounting bracket is included in this variant.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and can be ordered with manual or automatic drains, a 5 um element, different gauge scales, G (BSPP) or NPT threads, and with or without a bracket and check valve. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet and sizing 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, regulated air to the tool-change cylinders, clamps and air-blast nozzles on a CNC machining centre, with the 5 um element protecting tight-tolerance valves and the check valve holding the circuit if the shop supply dips.
Supplies clean, regulated air to the diverters, seal bars and pick-and-place cylinders on a carton or bagging conveyor line, where the 1/2 in port serves the larger header feeding several drop points.
Conditions the air feeding a lab automation or sample-handling rig, where the fine 5 um grade and a psi-referenced square gauge let technicians set and verify the regulated pressure for sensitive pneumatic stages.
Start with the port and size step: this unit is size 400 with a 1/2 in PT port; step up or down (200/300/400/600, 1/8 in to 1 in) to match the air consumption of the machines downstream. Choose the drain: differential-pressure (as here, drains on a set pressure drop), automatic, or manual. Choose the element: 40 um standard for general protection, 5 um (code W, as here) where finer dirt and water carryover control matters. Choose the gauge scale (MPa, psi or bar) and whether you want the embedded square gauge or the optional external round gauge. Thread is PT as standard, with G (BSPP) and NPT as order options; a bracket can be added, and the K option adds the reverse/check valve fitted here.
Because flow is published as curves and not as a single rated number, we do not quote a rated flow for this unit. Send us your application details and we will confirm the datasheet curves and check the sizing against your required flow 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 GFR series as curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number for this unit. Send us your application details and we will confirm the datasheet curves on request and check the sizing of this 1/2 in, size-400 unit against your required flow before you order.
The W in the code GFR400C15JF2WK selects the optional 5 um filter element in place of the 40 um standard element. The 40 um grade suits general protection of cylinders and valves; the 5 um grade is chosen where finer particulate and water carryover control matters, such as instrument air or precision valve stacks. Both grades are available across the GFR filter-regulator series, and the drain on this unit is the differential-pressure type.
