The AirTAC GFR40010JF2WGK 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 AirTAC GFR40010JF2WGK is a size 400 filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a G3/8 (BSPP) port, a 5 um filter element for finer filtration than the 40 um standard, a differential-pressure drain that bleeds condensate automatically when the pressure drop across the element rises, an embedded square gauge reading in psi, and a built-in reverse/check valve that holds downstream pressure when the supply is removed. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the unit is supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl is standard at this size.
This is a genuine AirTAC part from the GFR400 series. The GFR line is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and can be ordered with G (BSPP) or NPT threads in place of the PT standard, 40 um or 5 um elements, differential-pressure, automatic or manual drains, and MPa, psi or bar gauge scales. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and flow 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.

| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |

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 filtered, regulated air to the tool-change clamps and air-blast nozzles of a CNC machining centre, where the 5 um element protects fine valve spools and the check valve holds clamp pressure if the shop supply drops.
Regulating the air to stopper cylinders, pushers and diverters on a bottling or cartoning conveyor, with the differential-pressure drain keeping condensate out of the actuator valves between scheduled bowl checks.
Supplying steady, filtered air to pneumatic sample presses and purge fittings on a lab bench, where the psi-reading square gauge lets operators set and verify the working pressure at the point of use.
Size 400 with a 3/8 port sits in the middle of the GFR range; step up to 600 or down to 300/200 depending on the flow your line needs, and confirm the sizing against the published curves before ordering. The 5 um element in this model suits points of use that need finer air than the 40 um standard; the coarser grade is available if your application does not require it. The differential-pressure drain suits runs where the unit can be shut down periodically for the bowl to clear; an automatic drain is the choice where the unit runs continuously and manual draining is impractical. The square gauge here reads in psi; MPa and bar scales are order options. This unit carries a G (BSPP) thread; PT is the standard thread and NPT is available to order. Brackets are optional on this configuration. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before you order.
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 rather than a single rated figure, so no single rated flow number is quoted here. Tell us your line pressure and the flow your application needs and we will confirm the figures from the datasheet on request before you order.
The W in the code specifies the 5 um element, one grade finer than the 40 um standard, which suits points of use with sensitive valves or nozzles. The blank drain position is the differential-pressure type, which vents accumulated condensate automatically as the pressure drop across the element rises; automatic and manual drains are available as order options if your duty cycle needs them.
