The AirTAC GFR300C10MLC2GK 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 GFR300C10MLC2GK is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the low-pressure regulator type with a G3/8 (BSPP) port, a metal bowl with manual drain, a 40 um standard filter element, a fitted round pressure gauge reading in psi, a built-in reverse/check valve, and a mounting bracket included. 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 ports from 1/8 to 1 inch, plus options for drain type, filter grade, gauge style and scale, thread, and a reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm flow and other datasheet 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.

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.

Conditioning the supply to the pick-and-place cylinders and sealing jaws of a packaging line whose actuators are rated for low operating pressure, with the manual drain opened at shift end to clear collected condensate.
Feeding filtered, regulated air to the gate and stop cylinders on a bottling conveyor, where the fitted psi gauge lets operators set and verify the low setpoint the gating sequence requires.
Preparing compressed air for bench-top test rigs and pneumatic fixtures in a test lab, where the 40 um element protects instruments and the built-in check valve guards against reverse flow at the bench.
Size and port: this 300-size unit carries a G3/8 port; step up or down through sizes 200, 400 and 600 (ports 1/8 to 1 inch) to match the air demand of the circuit. Drain: this unit has a manual drain, so condensate is expelled by hand; automatic (code A) and differential-pressure (default) drains are available if you want hands-off removal. Filter grade: the standard 40 um element suits general air prep; specify code W for the 5 um element where finer filtration is needed. Gauge: the fitted round gauge reads in psi; the embedded square gauge and MPa or bar scales are alternatives. Thread: this unit is G (BSPP); PT is the standard thread and NPT is an order option. The regulation range of the low-pressure type is not published, and flow is published as curves rather than a single rating, so ask us to confirm both 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 GFR300 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 and sizing from the datasheet on request.
This is the low-pressure regulator version, intended where downstream equipment needs lower setpoints than the standard type; the exact regulation range is not published, so confirm it with us before ordering. The manual drain means an operator opens the drain valve by hand to expel collected condensate - choose the automatic (A) or differential-pressure drain codes if you want that handled without attention.
