The AirTAC GFR30010F3WT AirTAC Filter Regulator 3/8 in NPT 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 GFR30010F3WT is a GFR-series filter regulator: it removes water and particulate from compressed air and sets downstream pressure in a single compact body. This 300-size unit has a 3/8 in NPT port, a differential-pressure drain that bleeds condensate automatically as flow passes through, and the W-grade 5 um element for finer filtration than the standard 40 um element. The fitted embedded square gauge reads in bar, and the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi) with this drain type. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is published in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um (W) filtration, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Feeds clean, regulated air to the tool-change and clamping circuits of a CNC machining centre, where the 5 um element protects precision valves from fine particulate and the bar gauge lets setters verify set pressure at a glance.
Installed at the air drop feeding conveyor diverters and case-packing cylinders on a packaging line, combining water removal and pressure setting in one body so each station holds a consistent setpoint through the shift.
Mounted at a maintenance-bay bench for air impact wrenches and riveters, where the differential-pressure drain keeps condensate moving out during continuous tool use and the regulator is backed off between jobs to protect hoses and tools.
Size and port set the capacity: the 300 size with its 3/8 in port is the middle step of the range, so step up to 400 or 600 if your line draws more air, or down to 200 for lighter duty. This unit carries the 5 um (W) element - choose it when downstream valves, cylinders or instruments need finer protection than the 40 um standard element. The differential-pressure drain is the default and suits steady flow; pick automatic drain for intermittent duty or manual drain where you want controlled purging. The square gauge here reads in bar; MPa and psi scales and an external round gauge are alternatives. PT is the standard thread, with G and NPT as order options, and a mounting bracket is included.
Because AirTAC publishes flow for this series only as curves, not a single rated number, we cannot quote a flow figure here - 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 GFR series only as performance curves, not as a single rated figure, so we do not quote a flow number here. Tell us your application and required flow and we will confirm the correct size against the datasheet on request before you order.
The W in the code GFR30010F3WT selects the optional 5 um filtration grade. The 40 um element is the GFR standard and suits general plant air, while the 5 um element is chosen when downstream components need finer protection. Both grades are available across the GFR range, so you can pick the grade that matches each application.
