The AirTAC GFR300C10F2W AirTAC Filter Regulator PT3/8 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 AirTAC GFR300C10F2W is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 300-size unit is fitted with PT3/8 ports, a 5 um filter element (code W), a differential-pressure drain on the bowl, an embedded square gauge reading in psi, and a standard regulator with an adjustment range of 0.15-0.9 MPa (20-130 psi). The polycarbonate bowl is used on sizes 200-400, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and options include manual or automatic drains, the 40 um standard element, alternative gauge scales (MPa/psi/bar) or an external round gauge, G or NPT threads, and a low-pressure regulator type. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm 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.

Feeding filtered, regulated air to the gripper and capper cylinders on a beverage bottling line, where the 5 um element protects downstream valves from water carryover and particles.
Supplying regulated air to the diverter gates and stopper cylinders on a distribution-center conveyor, with the square psi gauge giving operators a local set-pressure readout at the machine.
Regulating supply pressure to the clamping cylinders on a CNC machining fixture, where a stable setpoint keeps workholding force consistent across shifts.
Choose the size by port and flow: this 300-size unit carries PT3/8 ports; step up to 400 or 600, or down to 200, as your line's air demand changes - we can check the published flow curves against your consumption before you order. The decodable choices on this family are the drain (differential-pressure as fitted here, or automatic or manual), the filter element (5 um as coded W here, or the 40 um standard), the gauge (embedded square, psi scale here; MPa or bar scales and an external round gauge are options), the thread (PT standard; G and NPT are order options), and the bracket.
Sizing against flow is the one decision we recommend confirming with us, since flow for this series is published as curves rather than a single rated figure - send us your operating pressure and consumption and we will verify the fit 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 GFR series as curves, not a single rated figure, so we do not quote a number here. Tell us your operating pressure and air consumption and we will confirm the flow from the datasheet for this 3/8 in unit before you order.
The GFR family takes a 40 um element as standard and a 5 um element as the W option. This model carries the 5 um grade, which suits lines with sensitive downstream valves, cylinders or instrumentation; the 40 um standard element remains available in the same size if coarser pre-filtration is preferred.
