The AirTAC GFR300C15MC2T AirTAC Filter Regulator NPT 1/2 in 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 GFR300C15MC2T is an AirTAC GFR300 filter regulator: filtration and pressure regulation combined in a single body for compressed-air lines. This configuration is decoded as a 1/2 in NPT port, a 40 um filter element, a manual drain on the bowl, a round pressure gauge reading in psi, and the standard regulator with an adjustment range of 0.05-0.9 MPa (7-130 psi). Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the bowl on this size 300 unit is PC (polycarbonate). A mounting bracket is included; no reverse/check valve is fitted.
This is a genuine AirTAC part from the GFR series, which is published in sizes 200, 300, 400 and 600 with port options in PT, G and NPT threads, a choice of differential-pressure, automatic or manual drain, an optional 5 um element (code W), and gauge scales in MPa, psi or bar. Flow figures for this series are published as curves rather than a single rating, so ask us and we will confirm the 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.

Clean, regulated air feeding tool-clamp and fixture actuators on a machining centre, with the 1/2 in NPT port matching the main drop to the cell and the psi gauge giving operators a local setpoint check.
A filter-regulator point of use on a bottling or cartoning line, conditioning the air that drives case-packing and sealing cylinders, with the manual drain emptied during scheduled line cleaning.
Regulated air for pneumatic presses and clamping fixtures along an assembly line, where the 40 um element protects valves and cylinders from water and particulate carryover from the main ring main.
Choose the GFR size by port and expected flow: this 300 unit steps up to a 1/2 in NPT port for lines that have outgrown 1/4 in or 3/8 in. Pick the drain to suit maintenance access: manual drain (this unit) needs someone to open it periodically, while automatic and differential-pressure drains handle it for you. The standard 40 um element suits general plant air; specify the 5 um W option where finer filtration is needed. Gauge scale is your choice of MPa, psi or bar - this unit carries the round gauge in psi. Thread is NPT here; PT is the standard thread and G (BSPP) is also a catalogue option. A bracket is included.
One honest note before you order: flow for the GFR series is published as curves, not as a single rated number, so send us your line conditions and we will confirm the sizing against the datasheet before you commit.
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 there is no one rated flow number we can honestly quote. Send us your line pressure and required flow and we will confirm the sizing against the datasheet on request.
The M in the code selects a manual drain on the filter bowl: collected water is released by hand at intervals you set. Automatic and differential-pressure drain versions are available in the same series if you would rather not rely on routine draining.
