The AirTAC GFR300C10LF2GK AirTAC Filter Regulator G3/8 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 GFR300C10LF2GK is an AirTAC GFR300 filter regulator: water and particulate filtration plus pressure regulation combined in a single body, with a G3/8 (3/8 in) port. This configuration is the low-pressure regulator type, fitted with a 40 um filter element, a differential-pressure drain, a metal bowl, an embedded square gauge reading in psi, a reverse (check) valve and a mounting bracket. Air passes the filter stage first, then the regulated outlet feeds the downstream circuit.
It is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, drain choices (differential-pressure, automatic or manual), an optional 5 um element (code W), gauge scale choices (MPa, psi or bar) and PT, G or NPT threads. Because AirTAC publishes flow as curves rather than a single rating, we confirm the datasheet and flow figures for your application 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.

| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |

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.

Feeding clamp cylinders on a packaging machine that hold at a reduced, regulated pressure, with the reverse (check) valve fitted in the supply line as part of this unit.
Conditioning and regulating air for gate and divertor actuators on a bottling line, where the 40 um element removes water and particles ahead of the regulated outlet.
Supplying regulated low-pressure air to a laboratory test bench or fixture, with the square psi gauge giving a direct pressure readout at the bench.
Choose the size and port step by the flow your line needs: this unit is size 300 with a G3/8 (3/8 in) port, and larger sizes carry larger ports and more flow. Within the family you can also select the drain type (differential-pressure as here, automatic, or manual), the filter grade (40 um standard, 5 um with code W), the gauge and its scale (MPa, psi or bar), the thread (PT standard; G and NPT are order options) and whether a bracket is fitted. This model is the low-pressure regulator type, so ask us to confirm its regulation range and the flow curve against your application before ordering - flow is published as curves, not a single rating.
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 performance 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 datasheet figures for this model on request.
The L in the code marks the low-pressure regulator type rather than the standard version. Its exact regulation range is not published in the catalogue, so we confirm it on request. The 1.0 MPa (145 psi) maximum inlet pressure and the -5 to 70 C (non-freezing) operating range still apply.
