The AirTAC GFR300C10MF1T 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 GFR300C10MF1T is a 300-size filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single compact body. This configuration carries a 3/8 in NPT port, a manual drain bowl, the standard 40 um filter element, an embedded square gauge scaled in MPa, and the standard (non low-pressure) regulator with an adjustment range of 0.05-0.9 MPa (7-130 psi). A 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 from the GFR filter-regulator line, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of manual, automatic or differential-pressure drains, an optional 5 um element (code W), gauge scale options, and G (BSPP), NPT or PT threads. Flow is published as curves rather than a single rating, so ask us to confirm flow and datasheet figures 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 clean, pressure-regulated air to the workpiece clamps and tool-change cylinders on a CNC machining center, with the square gauge letting setters verify set pressure at a glance.
Supplies filtered, regulated air to the flap-fold and taping cylinders of a carton-sealing conveyor, where the manual drain suits a line checked at every shift start.
Conditions the air feeding filler-valve and capper actuators on a bottling line, keeping water and scale out of the valves while holding a steady working pressure.
Start with the port step: this unit is the 300 size with a 3/8 in NPT port; step up to the 400 or 600 size if your line needs more flow capacity, or down to 200 for compact drops. Choose the drain to match maintenance access: manual (as here) suits attended installations, automatic suits unattended duty, and differential-pressure drain is the catalogue default. The standard element is 40 um; specify the W variant for 5 um finer filtration. The embedded square gauge is standard, with an external round gauge optional in MPa, psi or bar scales; PT is the standard thread with G (BSPP) and NPT as order options, and a bracket is included on this unit.
One honest note on sizing: AirTAC publishes flow as curves, not a single rated figure, so we do not quote a flow number here. Send us your application details and we will confirm sizing against the datasheet curves 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 curves, not as a single rated figure, so we do not quote a flow number on the product page. Tell us your application and we will confirm the flow from the datasheet on request before you order.
The M in the code specifies a manual drain bowl: collected condensate is released by hand at service checks. It suits installations that are visited regularly; for unattended duty choose the automatic drain (code A) or the differential-pressure drain (blank) in the same GFR300 series.
