The AirTAC GFR300C10MLC1T AirTAC Filter Regulator 3/8 in NPT 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 GFR300C10MLC1T is a GFR-series filter regulator: filtration and pressure regulation combined in a single body. It removes water and particulate from compressed air with its 40 um element, then regulates downstream pressure, so one unit does the job of a separate filter and regulator. This configuration is the size 300 body with a 3/8 in NPT port, a manual drain bowl, the low-pressure regulator type, a round pressure gauge reading in MPa, and a mounting bracket included. The maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, a choice of manual, automatic or differential-pressure drains, a 5 um element option, square or round gauges with MPa, psi or bar scales, and G, NPT or PT threads. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details for your application before ordering.

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.

Feeds filtered, regulated air to clamp and hold fixtures on a fabrication cell, where the low-pressure regulator type lets the line run clamps at a reduced setting instead of full header pressure.
Supplies cleaned air to the pusher and divertor cylinders that sort cartons on a bottling or food-packaging conveyor, with the manual drain bled during scheduled changeover stops.
Conditions the air feeding a machining-centre fixture panel and its low-pressure sensing or actuation devices, with the round MPa gauge giving the operator a direct read of the regulated line.
Start with the port and size: this unit steps up from the 1/4 in size-200 class to a 3/8 in NPT connection in the size-300 body, which suits lines carrying more air than a 1/4 in unit can serve. Choose the drain to match maintenance access: this version has a manual drain, which needs someone to bleed the bowl periodically, while automatic and differential-pressure drains are available if the unit will be hard to reach. The 40 um element is the standard grade; specify the W option for 5 um if finer particulate removal matters. The round gauge fitted here reads in MPa, and square or round gauges with psi or bar scales can be ordered instead. Thread is NPT as coded, with G (BSPP) and PT available as order options, and a bracket is included. Note that this is the low-pressure regulator type; its adjustment range is not published as a single figure, so tell us your set pressure and we will confirm suitability from the datasheet. Flow for the series is published as curves, not one rated number, so ask us to check the curve against your application 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 flow for the GFR series as performance curves rather than a single rated figure, so we do not quote one number. Send us your application details and we will confirm the flow curve and sizing from the datasheet on request.
The M in the code specifies a manual drain: condensate collected in the bowl is released by hand rather than automatically. Choose manual where the unit is accessible and drained during routine checks; choose the automatic or differential-pressure drain versions where the unit is mounted in a hard-to-reach position.
