The AirTAC GFR30010F2W AirTAC Filter Regulator PT3/8 5um 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 GFR30010F2W is a 300-size filter regulator that removes water and particulate from compressed air and sets downstream pressure in one body. This configuration carries a 3/8 in PT port, a fine 5 um filter element, a differential-pressure drain that bleeds condensate automatically as flow passes through, and an embedded square gauge reading in psi. The polycarbonate bowl suits the 300 size, a mounting bracket is included, and the standard regulator covers 0.15-0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi) at -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR range, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in and thread choices of PT (standard), G and NPT. Filter grade can be 40 um standard or 5 um fine, and gauge scales are offered in MPa, psi or bar. Flow is published as curves rather than a single rating, so we confirm flow and datasheet 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.

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 filtered, regulated air to the tool-clamp and pallet-change circuits on a machining centre, where the 5 um element helps protect close-tolerance valves from water and fine particles.
Sits ahead of solenoid valves and actuators on a packaging or process line, holding a steady set pressure to the control valves while the differential-pressure drain clears condensate during operation.
Regulates the supply to cylinders that divert, stop and lift product on a conveyor system, with the psi gauge giving operators a local reading at the drop.
Size and port set the flow path: the 300 size with a 3/8 in PT port sits mid-range in the GFR series, so step up to 400 or 600 for larger lines or down to 200 for compact circuits. The 5 um element in this model suits air that feeds sensitive components; the 40 um standard grade is fine for general-purpose drops. Drain choice matters: differential-pressure (as fitted here) drains with flow, automatic drains regardless of flow, and manual needs operator action. The square psi gauge is standard, with external round gauges and MPa/bar scales available, and G or NPT threads can be ordered instead of PT. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application 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 the GFR300 series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and required downstream flow and we will confirm the sizing against the datasheet on request before you order.
The W in the code GFR30010F2W selects the optional 5 um fine filter grade; 40 um is the standard element. Choose 5 um where downstream valves, cylinders or instruments need finer protection, and note the differential-pressure drain in this configuration bleeds collected condensate as air flows through the unit.
