The AirTAC GFR300C10LC2T AirTAC Filter Regulator NPT3/8 Low-Pressure 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 GFR300C10LC2T is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body. This size 300 unit is threaded NPT3/8 (3/8 in), is the low-pressure (L) regulator version, and carries the standard 40 um filter element with the differential-pressure drain. The bowl is metal, an external round gauge with a psi scale is fitted, the mounting bracket is included, and no reverse (check) valve is fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
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 catalogue options that include automatic or manual drains, a 5 um (W) filter element, embedded square or external round gauges with MPa, psi or bar scales, G (BSPP) or NPT threads in place of the PT standard, and bracket-less variants. Flow is published as curves rather than a single rating, so ask us to confirm the 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.

Filter and regulate the air feeding spray guns and air-assisted applicators on a finishing line, with the 40 um element catching pipe scale and condensed water before the gun and the fitted psi gauge setting the supply pressure.
Serve the gripper and stopper-cylinder circuits on a packaging conveyor, where one body filters the air and holds the downstream pressure the actuators were designed for.
Feed low-pressure circuits on textile and knitting machinery, where the low-pressure (L) regulator version is the intended choice for circuits running below standard regulator settings.
Pick the size by port and flow: this is size 300 with a 3/8 in NPT port; sizes 400 and 600 carry larger ports, size 200 smaller. Drain choice is differential-pressure (the standard, fitted here), automatic (A) or manual (M). Filter grade is the 40 um standard element as on this unit, or 5 um with code W. The gauge fitted here is the external round type with a psi scale; the embedded square gauge is the standard arrangement, with MPa or bar scales available. Thread is NPT (T) on this model; PT is the standard thread and G (BSPP) is also a catalogue option. Because flow is published as curves rather than a single rated figure, ask us to confirm sizing against your application 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 GFR flow as curves, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and provide the full datasheet for this unit on request.
This unit uses the differential-pressure drain, the standard arrangement, which discharges condensate using the pressure drop across the filter element. Automatic (A) and manual (M) drains are catalogue options across the GFR family if your circuit suits them better.
