The AirTAC GFR40010JF2WG AirTAC Filter Regulator G3/8, 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 GFR40010JF2WG is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a 3/8 inch (G3/8) G-thread port, a 5 um filter element for finer filtration than the standard 40 um grade, a differential-pressure drain that bleeds collected condensate automatically when flow runs, and an embedded square gauge reading in psi. The standard regulator covers 0.15-0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi), and the polycarbonate bowl suits ambient temperatures from -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR400 series, one of four sizes (200/300/400/600) spanning 1/8 to 1 inch ports. Options across the series include manual or automatic drains, the 40 um standard element, gauge scale choices of MPa, psi or bar, a reverse/check valve, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing or any datasheet figure 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.

Filtering and regulating the shop-air feed to a CNC machining centre, where the 5 um element protects spindle and tool-change components from water and fine particulate while the regulator holds a steady setting on the machine's actuator circuits.
Conditioning the air feeding cylinders and grippers on a packaging conveyor line, with the differential-pressure drain handling condensate during continuous running and the psi gauge letting operators verify the set pressure at a glance.
Serving a dedicated air drop at a paint spray booth, where the finer 5 um grade reduces water carry-over to the spray gun and the regulator keeps atomising pressure consistent across a shift.
Choose the GFR400 size by matching the 3/8 inch port step to your line size and required flow; larger sizes carry more flow. This unit already carries the finer 5 um element (code W) - step down to the standard 40 um grade if your application does not need fine filtration. The differential-pressure drain is the default and suits continuously flowing lines; specify an automatic drain for intermittent flow or a manual drain where an operator attends the unit. The square gauge here reads psi; MPa and bar scales are available, and an external round gauge is an option. Thread is G (BSPP) in this configuration, with PT and NPT offered as order options; no mounting bracket is included on this code. Because flow is published as curves rather than a single rating, send us your application details 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 figure, so we do not quote a number here. Send us your line size and application and we will confirm the flow from the datasheet on request before you order.
The W in the code specifies the optional 5 um element instead of the standard 40 um grade, giving finer filtration for sensitive downstream equipment. The blank drain position is the differential-pressure type, which discharges collected condensate automatically as flow passes through, with automatic and manual drains available as alternatives.
