The AirTAC GFR30010C2WTK AirTAC Filter Regulator 3/8 in NPT 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 GFR30010C2WTK is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This configuration carries a 3/8 in NPT port, the optional 5 um filter element, the differential-pressure drain, an external round gauge reading in psi, and a built-in reverse (check) valve that holds the downstream setting when upstream supply is interrupted. The bowl on this 300 size is polycarbonate (PC), and the 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 to 1 in, differential-pressure, automatic or manual drains, 40 um standard or 5 um elements, and gauges in MPa, psi or bar scales. Maximum inlet pressure is 1.0 MPa (145 psi), the regulation range on this unit is 0.15-0.9 MPa (20-130 psi), and operating temperature is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so ask us to confirm figures from the datasheet 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.

| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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.

Clean, regulated air to a small stamping or forming press: the 5 um element keeps debris out of the valve stack while the regulator holds a set pressure at the tool, read on the psi gauge.
Feeding sealing jaws and diverters on a packaging conveyor, where the built-in check valve holds the downstream setting through brief supply interruptions.
Point-of-use preparation at assembly benches: one body filters the shop air and sets line pressure, with the round psi gauge letting operators read the setting at a glance.
The real choices in this family are the size and port step (200/300/400/600, 1/8 to 1 in) matched to the flow your line needs; the drain type (differential-pressure as here, automatic, or manual); the filter element (40 um standard or 5 um where finer filtration protects downstream equipment); the gauge (embedded square or external round, in MPa, psi or bar scales - this unit has the round psi gauge); the thread (PT is the standard, with G and NPT as order options - this unit is NPT); the bracket; and the reverse/check valve. Because AirTAC publishes flow as curves rather than a single rated figure, send us your flow and pressure requirements 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves rather than a single rated figure, so we do not quote one number here. Send us your required flow and working pressure and we will confirm the sizing from the datasheet before you order.
The W in this model code specifies the optional 5 um element in place of the 40 um standard. Choose it when downstream valves, cylinders or instruments need finer filtration. Drain on this unit is the differential-pressure type, the catalogue default, so no drain-code letter appears in the model.
