The AirTAC GFR30010C2W AirTAC Filter Regulator 3/8in PT, 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 GFR30010C2W is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 300-size unit has PT3/8 ports, a 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain, and a round pressure gauge reading in psi. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi). Operating temperature is -5 to 70 C (non-freezing), and the polycarbonate bowl lets you see accumulated condensate at a glance.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, embedded square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Feeding the pneumatic cylinders and seal bars of a carton-sealing or wrapping line: the 5 um element protects valve spools from particulate and water carryover while the regulator holds a steady working pressure for consistent cycle timing.
Conditioning shop air ahead of a machining centre's pneumatic tool-change and clamping circuits, where the 5 um grade and stable regulated pressure help keep sensitive air-operated components working cleanly.
A filtered, regulated drop feeding air cylinders and grippers on a production assembly line, with the round psi gauge giving operators a visible setpoint and the differential-pressure drain handling condensate without manual attention.
Size and port are the first decision: this unit is size 300 with PT3/8 ports, one step up from 1/4 inch, so move to size 400 or 600 if your line needs more flow capacity. Filtration here is 5 um (code W); choose 40 um if coarser, general-purpose filtration is sufficient. The differential-pressure drain bleeds condensate automatically as flow passes through, with no drain fitting to reach; an automatic or manual drain can be ordered instead if your layout suits it better. The round psi gauge is fitted as specified; square-gauge and other scale options exist across the range. PT is the standard thread, with G and NPT available as order options, and a mounting bracket is included.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated number, so we do not quote a flow figure here. Send us your application details and we will confirm the datasheet and check the sizing with you before you order.
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 GFR series as curves rather than a single rated figure, so we do not quote a flow number here. Tell us your application and required flow, and we will confirm the datasheet figures and check that this 300-size, PT3/8 unit is correctly sized before you order.
The trailing W in the code selects the 5 um element, the finer of the two catalogue grades, suited to downstream equipment that needs cleaner air than the 40 um standard. If your application only needs general-purpose water and particulate removal, the 40 um version of the same filter regulator is available to order.
