The AirTAC GFR300C10C2WT AirTAC Filter Regulator NPT3/8 5 um is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet 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 GFR300C10C2WT is an AirTAC GFR300 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is a 300-size unit with a 3/8 in NPT port, a 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain, and an external round gauge reading in psi. The standard regulator covers 0.15-0.9 MPa (20-130 psi) with this drain type, the unit is rated to 1.0 MPa (145 psi) maximum inlet and -5 to 70 C (non-freezing), and the polycarbonate bowl suits the 300 size. A mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, differential-pressure, automatic or manual drains, 40 um or 5 um elements, and embedded square or external round gauges in MPa, psi or bar scales. Flow is published as curves rather than a single rating, so ask us to confirm the 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.

Filter and regulate the compressed air feeding a CNC machine's pneumatic valves, clamps and tool-change actuators. The 5 um element gives finer protection for the machine's air-side components, and the psi gauge lets setters verify the regulated line pressure at a glance.
Feed carton-sealing, wrapping or filling machinery where cylinders and air valves need clean air at a steady set pressure. The filter regulator sits at the line drop, the differential-pressure drain handles condensate, and the round psi gauge supports repeatable set-point checks.
Prepare air ahead of spray guns on a finishing line, where water and particulate in the supply ruin finish quality. This unit strips water and 5 um particulate and holds the regulated pressure the guns were set up with, with the psi gauge confirming the setting between shifts.
Size and port step up together: 200, 300, 400 and 600 carry ports from 1/8 in to 1 in, so match the 3/8 in NPT port on this unit to your line size and required flow. Drain choice matters: differential-pressure (this unit) handles condensate as pressure drops, automatic suits unattended duty, and manual suits intermittent or inspected installations. Filter grade is 40 um standard or 5 um (this unit, code W) for finer downstream protection. Gauges come embedded square or external round, in MPa, psi or bar scales; thread is PT as standard with G and NPT as order options, and a bracket is included unless code J. 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 as curves rather than a single rated figure, so we do not quote a number here. Tell us your application and line conditions and we will confirm the datasheet flow curve and check the sizing with you before you order.
The 40 um grade is the catalogue standard for general air preparation, while the 5 um element (code W) is the finer option for downstream equipment that needs cleaner air. This unit carries the 5 um element; both grades share the same GFR300 body, 3/8 in port and regulation range, so the choice is about the air quality your equipment needs.
