The AirTAC GFR30010C1WT AirTAC Filter Regulator NPT3/8 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 GFR30010C1WT is an AirTAC GFR300 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure at your set point. This configuration is 3/8 in NPT thread, fitted with a 5 um filter element, a differential-pressure drain, and a round pressure gauge scaled in MPa. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the polycarbonate bowl suits non-freezing compressed-air service from -5 to 70 C.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, filter grades of 40 um (standard) or 5 um (code W), differential-pressure, automatic or manual drains, optional G (BSPP) or NPT threads, and gauge scales in MPa, psi or bar. Flow is published as curves rather than a single rated figure, so we confirm datasheet and sizing numbers 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.

Point-of-use filter regulator feeding clean, set-pressure air to tool clamps and workholding actuators on a machining centre, with the 5 um element protecting pilot valves from particulate.
Conditioning the air supply to carton sealers and case-packing cylinders, holding a stable regulated pressure so gripper and pusher strokes stay repeatable through the shift.
Filtering and regulating shop air feeding pneumatic valves and fixtures on a lab or QA test bench, where the 5 um grade and a visible MPa gauge keep the supply clean and set correctly.
Size 300 with a 3/8 in port sits mid-range in the GFR line; step up or down through sizes 200, 400 and 600 as your flow demand changes. This unit carries the 5 um element (code W), the finer option over the 40 um standard where downstream valves and cylinders need cleaner air, and the differential-pressure drain, which purges bowl condensate without a manual twist. The gauge here is round with an MPa scale; psi and bar scales are available, and G (BSPP) or NPT threads can be ordered in place of the PT standard. Flow is published as curves, not 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 rather than a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the datasheet flow curves and check the sizing for you on request.
The W code in GFR30010C1WT selects the optional 5 um filter element, one grade finer than the 40 um standard, for downstream equipment that needs cleaner air. If your line does not need the finer grade, the 40 um version of the same size is available.
