The AirTAC GFR40015AJC2WTK AirTAC Filter Regulator NPT1/2 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 PT1/2" ports, a automatic 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 GFR40015AJC2WTK is a size 400 GFR filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built with a 1/2 in NPT port, 5 um filtration (the finer W grade, versus the 40 um standard element), an automatic drain that ejects collected condensate without manual attention, a round pressure gauge reading in psi, and a reverse/check valve fitted. The polycarbonate bowl lets you see the condensate level at a glance, and the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi).
This is a genuine AirTAC part from the GFR400 series. The GFR line runs from size 200 through 600, with port sizes from 1/8 in to 1 in, PT/G/NPT thread options, manual or automatic drains, 40 um or 5 um filtration, and MPa/psi/bar gauge scales. We confirm flow and datasheet figures on request, since flow is published as curves rather than a single rating.

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 plant-air drop that runs a pneumatic press: the 5 um element keeps sludge and fine particulate out of the press valve stack while the regulator holds a steady working pressure at the machine.
Conditioning air ahead of a packaging line's cylinder and gripper manifold, where the automatic drain handles condensate on a line that runs unattended across shifts and the check valve holds settings through supply dips.
Supplying clean, regulated air to laboratory automation and sample-handling equipment, where the finer 5 um grade protects sensitive pneumatic components and the psi gauge gives operators a direct local reading.
Size 400 with a 1/2 in port sits in the upper-middle of the GFR range, so step up or down by port size to match the air demand of the line; we will confirm the flow curve against your application before you order. The 5 um element on this unit suits downstream equipment that needs cleaner air than the 40 um standard grade delivers. The automatic drain suits unattended or hard-to-reach installations; choose manual drain only where someone checks the bowl routinely. The round psi gauge is an optional external fitment over the embedded square gauge, and scales are available in MPa, psi or bar. Thread here is NPT; PT is the standard and G is also an order option. This unit ships without a mounting bracket (code J), and the fitted check valve holds downstream pressure if the upstream supply drops. Max inlet pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C, non-freezing.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The reflux valve permits reverse flow 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 we do not quote a figure that could mislead your sizing. Send us your application's air demand and line pressure and we will confirm the flow curve and sizing from the datasheet before you order.
The A in the code selects the automatic drain, which ejects collected condensate on its own instead of waiting for a manual bowl purge, and the W selects the 5 um element rather than the 40 um standard grade. Both are decodable order options on the GFR400 series, so you can specify manual drain or the 40 um grade if your installation prefers them.
