The AirTAC GFR30010F2WT AirTAC Filter Regulator NPT3/8 | 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 GFR30010F2WT is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure in one compact body. This configuration carries a 3/8 in NPT port, a 5 um filter element for finer filtration than the standard 40 um grade, a differential-pressure drain that bleeds condensate automatically as air passes through, and an embedded square gauge scaled in psi. The regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), the polycarbonate bowl suits the 300 size, and a mounting bracket is included.
This is a genuine AirTAC part from the GFR300 series. The GFR line spans sizes 200 to 600 with ports from 1/8 to 1 in, PT as the standard thread and G or NPT as order options, filter grades of 40 um standard or 5 um (code W), and manual, automatic or differential-pressure drains. Rated inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm datasheet figures for your application.

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 fine valve spools from particulate and the regulator holds a steady clamp pressure.
Conditions the air feeding pipettes, valves and actuated manifolds on a lab automation skid, where the psi-scaled square gauge gives operators a direct reading and the differential drain keeps the bowl clear without daily attention.
Supplies filtered, regulated air to the diverter gates, seal bars and vacuum-assist cylinders on a packaging conveyor line, keeping actuator speed consistent through a full shift.
Size and port are the first choice: the 300 series with a 3/8 in NPT port sits mid-range in the GFR line, and the right size depends on the flow your line needs - which is published as curves, not a single rating, so let us check the curve against your demand before you order. This unit already locks in the finer 5 um element (choose 40 um where only coarse water and pipe scale are the concern) and the differential-pressure drain, which needs no operator attention; a manual drain suits intermittent duty and an automatic drain suits unattended lines. The embedded square gauge here is scaled in psi; MPa and bar scales are available, and an external round gauge is an option. NPT is ordered as this code's thread option - PT is the catalogue standard and G (BSPP) is also available. A mounting bracket is included.
Because flow data exists only as catalogue curves, we recommend confirming sizing against your application with us before ordering.
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 series as curves rather than a single rated figure, so we do not quote a l/min or SCFM number. The GFR300 size with its 3/8 in port sits mid-range in the GFR line. Send us your flow and pressure requirement and we will confirm the right size from the datasheet curves before you order.
The W code in GFR30010F2WT selects the optional 5 um element instead of the standard 40 um grade, giving finer protection for sensitive downstream components. The drain code is blank, which is the differential-pressure type: it vents collected condensate automatically as air flows through, with no manual draining. A manual (M) or automatic (A) drain can be ordered instead if your duty cycle suits it.
