The AirTAC GFR300C10MF2WG AirTAC Filter Regulator G3/8 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 GFR300C10MF2WG is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, both in a single body. This configuration is built with a G3/8 (BSPP) port on the size-300 frame, a fine 5 um filter element, a manual drain for scheduled bowl draining, an embedded square gauge reading in psi, the standard regulator type, and a mounting bracket included. No reverse/check valve is fitted.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of drain type, 40 um standard or 5 um fine filtration, gauge scale, and PT (standard), G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi), the regulation range on this manual-drain version is 0.05-0.9 MPa (7-130 psi), and the working temperature range is -5 to 70 C, non-freezing. At size 300 the bowl is polycarbonate. Flow is published as curves rather than a single rating, 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.

Feeding filtered, pressure-regulated air to the clamp and fixture cylinders on a CNC machining cell, where a 5 um element helps protect the clamping valves from water and swarf carryover.
Supplying regulated air to the pusher and carton-sealing cylinders along a packaging conveyor, with the psi square gauge letting operators check the set point at a glance.
Conditioning the compressed air feeding actuators and air bearings on a laboratory test rig, where fine 5 um filtration and a stable regulated pressure keep test conditions repeatable.
Choose the size by the port step and the flow your line needs: size 300 with its 3/8 port sits in the middle of the GFR range, and the larger sizes carry more flow. Decide the drain first: manual (this unit) means someone drains the bowl on a schedule, while automatic or differential-pressure drains suit unattended installations. Pick 5 um (this unit) when downstream valves and cylinders need finer air than the 40 um standard element provides. Select the gauge scale - MPa, psi or bar - to match the rest of your panel, and match the thread to your piping: PT is the standard, with G and NPT available as order options. Brackets are included on this unit.
One honest note before ordering: AirTAC publishes flow as curves, not as a single rated figure, so send us your application's flow and pressure requirements and we will confirm the correct size from 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 GFR300 as curves rather than a single rated figure, so there is no one number we can honestly quote. Tell us your required flow and working pressure and we will confirm the sizing directly from the datasheet on request.
The M in the code specifies a manual drain: the bowl is drained by hand on a scheduled basis, which suits attended installations. If the unit will run unattended, the GFR300 is also available with an automatic or a differential-pressure drain - ask us and we will quote the right code.
