The AirTAC GFR300C10MC2TK AirTAC Filter Regulator NPT3/8 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 GFR300C10MC2TK is a 300-size filter regulator: one body strips water and particulate from compressed air and holds downstream pressure steady. This configuration has NPT3/8 ports, a manual-drain polycarbonate (PC) bowl, the standard 40 um filter element, a fitted round gauge reading in psi, a reverse/check valve, and the mounting bracket included. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), and the working temperature range is -5 to 70 C (non-freezing).
It is a genuine AirTAC part. The GFR family runs in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, plus drain, filter-grade, gauge, thread and bracket options, so most supply points can be matched from the catalogue. Flow is published as curves rather than a single rating; 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.

Mounted at the machine drop to remove condensed water and chips-laden particulate and hold a set pressure for the tool-clamp and blow-off circuits on a CNC machining center.
Feeding diverters, stoppers and pusher cylinders on a distribution-center conveyor line, where a stable regulated supply keeps stroke timing consistent through the shift.
Serving pneumatic nutrunners, clamps and presses at a bench assembly station, with the psi gauge giving the operator a local reading of the set line pressure.
Every choice in this code is decodable: the 300 size with NPT3/8 ports sits mid-range for typical machine supply air; the M orders a manual drain, which also unlocks the widest 0.05-0.9 MPa (7-130 psi) regulation range and suits points drained on a schedule; the standard 40 um element is fitted (a 5 um element is available as code W); the round gauge reads in psi; and the T orders NPT thread in place of the PT standard, with G (BSPP) also a catalogue option. The K adds a reverse/check valve and the bracket is included. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 GFR300 flow as curves rather than a single rated figure, so no flow number is quoted here. Send us your application details and we will confirm the datasheet flow curve and sizing on request before you order.
The M in GFR300C10MC2TK orders the manual-drain bowl: condensate is released by operating the drain by hand on a schedule, and manual drain also gives the full 0.05-0.9 MPa (7-130 psi) adjustment range. Automatic (A) and differential-pressure (blank) drains are catalogue options on the same 300-size body if you prefer not to rely on operator rounds.
