The AirTAC GFR300C10MJF2 AirTAC Filter Regulator PT3/8, Manual Drain 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 GFR300C10MJF2 is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint, all in one body. This configuration is sized for PT3/8 ports, uses the standard 40 um filter element, and drains by hand - you open the manual drain valve to expel collected condensate. The embedded square gauge reads in psi, and the standard regulator covers a 0.05-0.9 MPa (7-130 psi) adjustment range. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature is -5 to 70 C, non-freezing. The bowl on this unit is metal, and no mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options across the family include automatic or differential-pressure drains, a finer 5 um element (code W), round or square gauges with MPa, psi or bar scales, G (BSPP) or NPT threads, and a mounting bracket. Flow for the GFR300 is published as curves rather than a single rated figure, 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.

Feeding clean, regulated air to the clamp and swing cylinders on an automated machining or assembly fixture. The 40 um element keeps pipe scale and rust out of the directional valves, and the manual drain suits a shift-end blowdown routine.
Supplying filtered, pressure-controlled air to the tape heads, flap tuckers and pusher cylinders on a carton-sealing conveyor. A stable setpoint read on the psi gauge keeps actuator speeds consistent from the first carton to the last.
Conditioning shop air ahead of a plasma cutter at a fabrication bench: the filter stage strips water and particulate that cause torch and consumable problems, while the regulator holds the pressure the torch controls expect.
Choose the size by port and air demand: step up from 300 to 400 or 600 when your consumption outgrows a 3/8 inch line, or down to 200 for compact circuits. Pick the drain to match attendance: manual (this unit) for a routine blowdown, automatic where nobody is nearby, or differential-pressure as the family default. The standard element is 40 um; specify 5 um (code W) for finer protection of downstream valves and cylinders. The square gauge on this unit reads psi; MPa and bar scales are available. Thread is PT as standard, with G (BSPP) and NPT as order options, and this code omits the optional mounting bracket. Because flow is published as curves rather than a single rating, send us your demand 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 GFR300 flow as curves, not as a single rated number, so we do not quote a figure here. Tell us your inlet pressure, set pressure and air demand, and we will confirm the flow from the datasheet on request before you order.
M is the manual drain. You open the drain valve by hand to expel the water collected in the bowl, which suits installations that are checked regularly. The same family is also available with an automatic (A) or differential-pressure (blank) drain if you prefer unattended moisture removal.
