The AirTAC GFR30010JF2WG AirTAC Filter Regulator G3/8, 5 um, psi gauge 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 GFR30010JF2WG is an AirTAC GFR300 filter regulator: water and particulate filtration plus pressure regulation combined in a single body, with a 3/8 in (G3/8) G-thread port. This configuration carries the finer 5 um filter element (code W) instead of the 40 um standard, a differential-pressure drain, and an embedded square gauge reading in psi. The standard regulator covers a set-pressure range of 0.15-0.9 MPa (20-130 psi), with a maximum inlet (working) pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing).
It is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of drain (differential-pressure, automatic or manual), 40 um or 5 um filtration, gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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.

Point-of-use cleanup and pressure setting on the air drop feeding a CNC machining center: water and particles are stripped from the compressed air before it reaches tool-clamping and tool-change circuits, and the regulator holds the set pressure those circuits were designed around.
Supplying cleaned, regulated air to the pneumatic cylinders on a carton case-sealing station of a packaging conveyor, so the seal and flap-fold actuators see steady pressure and the 5 um element helps protect the cylinder seals from particulate carryover.
Feeding the air supply of a laboratory autosampler or robotic sample handler, where the 5 um filtration grade and a stable regulated set pressure support consistent actuator movement and help keep sensitive pneumatic components free of water and debris.
Size 300 with a G3/8 (3/8 in) port suits circuits plumbed at 3/8 in; step up to size 400 or 600 where higher flow is needed - send us your demand and line pressure and we will check the published flow curves with you before you order. The 5 um element (code W) is the finer of the two grades (40 um is standard); choose it where downstream equipment needs cleaner air. Drain on this unit is differential-pressure, which vents the bowl as inlet pressure falls; automatic (A) or manual (M) codes are available if you prefer a different drain style. The embedded square gauge reads psi; MPa and bar scales, and an external round gauge, are alternatives. Thread is G (BSPP); PT is the standard thread and NPT is an order option. This J-coded unit comes without a mounting bracket.
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 this family as curves rather than a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Send us your line pressure and the air demand of your equipment and we will confirm the sizing against the datasheet curves on request before you order.
The W in the code GFR30010JF2WG selects the optional 5 um element; the catalogue standard for GFR units is 40 um. The 5 um grade is the right choice when downstream valves, cylinders or instruments need finer particle removal. If your application is happy with general-purpose filtration, the 40 um version of the same size is available.
