The AirTAC GFR300C10C2G AirTAC Filter Regulator G3/8, 3/8 in 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 GFR300C10C2G is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in one body. This size 300 unit is threaded G3/8 (BSPP), carries the 40 um standard filter element, drains its polycarbonate bowl by differential pressure, and is fitted with an external round gauge reading in psi. The standard regulator covers 0.15-0.9 MPa (20-130 psi) with this drain type, and maximum inlet pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C (non-freezing), medium is compressed air only.
This is a genuine AirTAC part. The GFR300 series sits within the G-family size range (200/300/400/600) with options including 5 um filtration (code W), automatic or manual drains, embedded square or external round gauges in MPa/psi/bar scales, G or NPT thread variants, and bracket choices. Flow is published as curves rather than a single rating, so ask us to confirm datasheet figures against 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.

Point-of-use conditioning ahead of the directional valves on a packaging machine's pick-and-place circuit: the 40 um element strips water and debris while the regulator holds a steady actuation pressure, with the psi gauge giving a visible setpoint.
Mounted at the air drop of a manual assembly cell, the GFR300C10C2G gives operators a locally adjusted, filtered supply for air tools, clamps and small cylinders, with the round gauge letting staff verify pressure at a glance.
Conditioning the drive air for gating and diverter cylinders on a bottling conveyor, where stable regulated pressure keeps divert timing consistent and the 40 um element protects the gate valves from rust and scale in the drop leg.
Size 300 with a 3/8 in port sits mid-range in the GFR line; step to size 200 or 400 as your flow demand dictates - we confirm sizing from the published curves before you order. The 40 um element suits general plant air; specify the W-code 5 um element where finer protection is needed. This unit drains its polycarbonate bowl by differential pressure; automatic (code A) and manual (code M) drain variants exist if your duty calls for them. The fitted round gauge reads psi; the embedded square gauge and MPa or bar scales are the alternatives. Thread here is G (BSPP) - PT is the standard thread and NPT is an order option - and the mounting bracket is included.
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 GFR300 flow as curves, not as a single rated figure, so we do not quote one number. Send us your application's flow and pressure requirements and we will confirm sizing from the datasheet on request.
The embedded square gauge is the GFR standard; the C2 in this model code specifies the optional external round gauge with a psi scale (MPa and bar scales are also available). If you prefer the square gauge or a different scale, that variant can be specified instead.
