The AirTAC GFR300C10JF2T AirTAC Filter Regulator NPT3/8 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 GFR300C10JF2T 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 standard 40 um filter element, a differential-pressure drain and the embedded square gauge scaled in psi. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the polycarbonate bowl suits non-freezing compressed air from -5 to 70 C. No mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options include automatic or manual drains, a 5 um element (code W), MPa/psi/bar gauge scales, an external round gauge, a reverse/check valve, G or NPT threads in place of the PT standard, and a mounting bracket. Flow is published as curves rather than a single rating, so ask us to confirm the 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.

Filtered and regulated air for the pneumatic clamping cylinders on a carton-sealing line, where the 40 um element keeps scale and pipe rust out of the clamp valves and the regulator holds the set pressure downstream.
Point-of-use regulation for the air supply feeding tool-change cylinders on a machining centre, with the psi-scaled square gauge giving the operator a local pressure readout at the machine.
Pilot air for the directional control valves that divert containers between lanes on a bottling conveyor, with the differential-pressure drain suited to lines with steady airflow through the bowl.
Size the unit by the port step: GFR covers 200, 300, 400 and 600 as port size and flow demand rise, and this size 300 unit carries a 3/8 in NPT port. Choose the drain: differential-pressure (this code), automatic (A) or manual (M) - note the manual-drain version widens the regulation range to 0.05-0.9 MPa (7-130 psi) versus 0.15-0.9 MPa (20-130 psi) here. Pick the element: 40 um standard or 5 um with code W. Gauge scale is selectable (MPa, psi or bar) with an external round gauge as an option; threads can be ordered in G or NPT instead of the PT standard; a bracket and a reverse/check valve (K) are optional and not fitted on this code. Because flow is published as curves rather than a single rating, send us your application and we will confirm sizing from 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 G-series flow as curves rather than a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and the full datasheet figures for this exact model on request.
Yes. The gauge is offered in MPa, psi or bar scales with an external round gauge as an option, and the drain can be specified as automatic (A) or manual (M) instead of the differential-pressure drain fitted here. This code carries the square gauge scaled in psi.
