The AirTAC GFR300C10AJF2G AirTAC Filter Regulator G3/8 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 GFR300C10AJF2G is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a G3/8 (3/8 in) port, a 40 um standard filter element, an automatic drain on a polycarbonate bowl, and a standard regulator with an adjustment range of 0.15-0.9 MPa (20-130 psi). A square pressure gauge graduated in psi is fitted; no mounting bracket and no reverse/check valve are included in this version.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, manual or automatic drain choices, an optional 5 um element (code W), and G or NPT thread variants as order options alongside the PT standard. Max 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 sizing and 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.

Point-of-use conditioning for a CNC machining centre: clean, regulated air to the tool changer and clamping circuits, with the automatic drain handling condensate between shifts.
Conditioning the supply to pick-and-place cylinders and product diverters on a packaging conveyor line, holding a steady set pressure as stations cycle throughout the run.
Feeding clamp and press fixtures on an automotive assembly cell, where filtered, regulated air protects the valves and cylinders doing the clamping work.
Size 300 sits in the middle of the GFR range: step up or down (200/400/600) according to the port size and flow your line needs, matching the 3/8 in port to your piping. Choose the drain to suit the duty: the automatic drain on this unit empties the bowl without attention, the manual type relies on an operator, and the differential-pressure drain is the catalogue default. The 40 um element is standard; specify code W for the 5 um grade where finer filtration is needed. Gauge scale (MPa, psi or bar), thread (PT standard, G or NPT to order) and bracket are all decodable choices. Flow is published as curves rather than a single rated figure, so send us your flow requirement 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. 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 as a single rated figure, so we do not quote a number here. Send us your line pressure and required flow and we will confirm sizing from the datasheet on request.
This configuration carries code A, so the bowl drains condensate automatically. A manual-drain version (code M) is available in the same size if you prefer operator-controlled draining, and the differential-pressure drain is the catalogue default.
