The AirTAC GFR300C10MLF2T AirTAC Filter Regulator NPT3/8 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 GFR300C10MLF2T is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This 300-size unit is configured with a 3/8 in NPT port, a 40 um standard filter element, a manual drain on the metal bowl, and the low-pressure regulator type. An embedded square gauge with a psi scale is fitted so the downstream setting can be read directly, and a mounting bracket is 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 is published in sizes 200, 300, 400 and 600 with a choice of ports and threads (PT as standard, with G and NPT as order options), drain types, 40 um or 5 um (W) filter grades, gauge styles and scales, and standard or low-pressure regulator types. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application.

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.

Fixture and clamp circuits that must hold workpieces at a reduced supply pressure get filtration and regulation in one body, with the psi-scale square gauge letting the setter read the clamping setting directly at the cell.
On cartoning and wrapping machines with many small cylinders and valves, a single GFR300 point-of-use unit cleans the air of water and swarf and holds a stable low setting to the actuator bank, with the manual drain emptied at planned stops.
Bench-top tooling, air bearings and low-pressure actuated fixtures need clean, moisture-free air at a gentle, repeatable setting - the low-pressure regulator type and 40 um element in this 300-size unit are specified for exactly that role.
Size and port set the air capacity: the 300 size with its 3/8 in NPT port sits mid-range in the GFR line between the 200 and the larger 400/600 units, so step up or down if your line flow demands it. This configuration carries a manual drain - choose automatic (A) or differential-pressure (blank) instead if the bowl cannot be drained by hand on your maintenance schedule. The 40 um element is the standard grade; specify the W code for the 5 um option where finer filtration is needed. The fitted square gauge reads in psi; MPa or bar scales and an external round gauge are alternatives. Thread here is NPT; PT is the catalogue standard and G is also available. A bracket is included with this unit.
Because flow is published as curves and not as a single rated figure, we do not quote a flow number here - send us your application details and we will confirm sizing against the datasheet before you order. The exact regulation range of the low-pressure type is likewise confirmed on request.
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 curves rather than as a single rated figure, so we do not quote a flow number for this unit. Send us your line conditions and required capacity and we will confirm the sizing from the datasheet on request before you order.
The M in GFR300C10MLF2T specifies a manual drain, meaning collected water is emptied from the metal bowl by hand as part of your maintenance routine. If you prefer the bowl to discharge itself, the same 300-size filter regulator is available with an automatic drain (code A) or the default differential-pressure drain - just ask for the alternative code.
