The AirTAC GFR300C10MJF2TK 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 GFR300C10MJF2TK is an AirTAC GFR300 filter regulator: filtration and pressure regulation combined in a single body for compressed air. It removes water and particulate down to 40 um and holds your set downstream pressure within a 0.05-0.9 MPa (7-130 psi) adjustment range. This configuration is a 3/8 in NPT-port unit with a manual drain, an embedded square gauge reading in psi, a built-in reverse/check valve, and no mounting bracket. 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 series is available in sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, PT, G and NPT threads, manual, automatic or differential-pressure drains, a 5 um filter grade option, and gauge choices. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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.

Installed at the point of use on a compressed-air drop, it cleans water and chips from the supply and lets the cell operator set a stable working pressure for the tools and actuators below.
Feeding cylinders and grippers on a packaging or conveyor line, the unit keeps debris and condensate out of the valves while the regulator holds the pressure the pick-and-place sequence was tuned for.
At a maintenance bench or tool station, the 3/8 in port feeds impact wrenches, spray guns and air ratchets, with the psi gauge giving a clear readout and the check valve holding the setting when supply dips.
Size 300 with a 3/8 in port is a mid-range step in the GFR line; step up to 400 or 600, or down to 200, if your line needs a different port and flow envelope. Because flow is published as curves, not a single rating, ask us to confirm sizing against your application before ordering. This unit has a manual drain, so plan a routine drain check; automatic and differential-pressure drains are available on other variants. The 40 um element is the standard grade - specify the W option if you need 5 um. The fitted square gauge reads in psi; MPa and bar scales and an external round gauge are options. NPT thread is fitted here, with PT and G available to order, and a mounting bracket can be added if you want panel fixing.
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 this series as curves, not as a single rated number, so there is no one figure we can quote. Tell us your working pressure and air demand and we will confirm the flow and sizing from the datasheet on request before you order.
The M in the code specifies a manual drain: collected water is released by operating the drain by hand, so it suits installations that are checked as part of a routine. If you prefer unattended draining, the GFR300 is also offered with an automatic or a differential-pressure drain.
