The AirTAC GFR300C15MF2T AirTAC Filter Regulator NPT1/2 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 GFR300C15MF2T is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This 300-size unit is threaded NPT1/2, carries a manual-drain polycarbonate bowl, a 40 um standard filter element and an embedded square gauge reading in psi. The regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), 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. The GFR family is offered in 200, 300, 400 and 600 sizes with PT, G (BSPP) or NPT threads, a choice of manual, automatic or differential-pressure drains, an optional 5 um (W) filter element, gauge scale choices and low-pressure variants. Flow is published as curves rather than a single rating, so ask us to confirm sizing and 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.

Point-of-use water and particulate removal plus a set working pressure for the air drops feeding CNC machine-tool actuators, chucks and tool-change cylinders, with the psi gauge letting setters verify the setting at a glance.
Clean, regulated air for the pneumatic cylinders and grippers on a carton-forming and sealing conveyor, where the manual drain suits a line that is checked at each shift start.
A filter regulator ahead of the solenoid valve stacks on textile weaving machines, keeping condensed water and line scale out of the valves while holding a stable downstream pressure.
Size and port step up together: 200, 300, 400 and 600 cover ports from 1/8 in to 1 in, so pick the size whose flow curve meets your demand - this unit is 300 size with a 1/2 in NPT thread. Choose the drain to suit service: manual (as here) needs periodic draining by hand, automatic drains on its own, and differential-pressure drains while the bowl is under pressure. The standard element is 40 um; specify the W code for 5 um where downstream equipment needs finer filtration. Gauge scale can be MPa, psi or bar, and the thread can be ordered in PT, G or NPT. Flow is published as curves, not a single rating, so send us your flow and pressure requirements and we will confirm sizing against the datasheet 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 rather than a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm sizing from the datasheet on request.
The M in the code specifies a manual drain: the bowl must be drained periodically by hand. AirTAC also offers automatic and differential-pressure drain variants in the same sizes, so a different drain type can be ordered if the installation is not checked regularly. The standard filter element is 40 um; a 5 um element is available with the W code.
