The AirTAC GFR300C10LF1T AirTAC Filter Regulator 3/8 NPT 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 AirTAC GFR300C10LF1T is a size 300 filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This configuration has a 3/8 in NPT port, the standard 40 um filter element, a differential-pressure drain that bleeds condensate as air flows through, and a metal bowl. It is the low-pressure (L) type; its exact adjustment range is not published, so we confirm it from the datasheet on request. A square pressure gauge on the MPa scale is fitted, a mounting bracket is included, and no reverse/check valve is fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and with choices of drain type, 40 um or 5 um filtration, gauge style and scale, and PT, G or NPT thread. Flow is published as curves rather than a single rated figure, so send us your application details and we will confirm the sizing and datasheet figures on request.

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.

Filtering and regulating the air feeding pick-and-place cylinders on a carton-forming packaging line, with the 40 um element protecting valve seals from particulate and the differential-pressure drain handling condensate as the line runs.
Conditioning air ahead of a solenoid-valve manifold on an assembly station: filtration upstream of the valves and a steady regulated supply to the downstream actuators from one compact body.
Air preparation for gripper and pusher cylinders on a bottling conveyor, with the fitted square MPa gauge giving the line technician a direct pressure readout at the unit.
Size and port step up together across the GFR range (200/300/400/600, 1/8 to 1 in), so choose the size whose flow curve covers your demand rather than matching the port thread alone. Drain options are differential-pressure (standard, and fitted here), automatic (A) or manual (M). Filtration is 40 um as standard or 5 um with code W. Gauges are an embedded square gauge (MPa, psi or bar scales) or an optional external round gauge. Thread is PT as the standard, with G and NPT as order options, and a mounting bracket is included unless code J specifies otherwise. Flow is published as curves, not a single rating, so 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 flow for the GFR series as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow curve and correct sizing from the datasheet on request.
It marks the low-pressure regulator type. The exact adjustment range for this variant is not published, so we confirm it from the datasheet on request. The rest of the decode is standard for this unit: 3/8 in NPT port, 40 um filtration, differential-pressure drain and a fitted square gauge on the MPa scale.
