The AirTAC GFR300C10MJF2WG AirTAC Filter Regulator G3/8, 5 um 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 GFR300C10MJF2WG is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one compact body. This configuration is the size 300 unit with a G3/8 (BSPP) port, a 5 um filter element for finer filtration than the standard 40 um grade, a manual drain on the bowl, and an embedded square gauge reading in psi. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and no mounting bracket is fitted. 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 family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and options include drain type, filter grade, gauge style and scale, thread form and bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and flow 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.

Filtered and regulated air at a machining centre's pneumatic drop, where the 5 um element protects tool-clamp and chip-clearing valves from water and fine particulate.
A conditioning point feeding stopper and pusher cylinders on a packaging conveyor, with the square psi gauge giving operators a local setpoint readout.
Conditioned air to filler and capping heads on a bottling line, where the manual drain suits a station checked during each shift's housekeeping round.
Size 300 with a G3/8 port suits lines where the required flow sits in the mid range of the GFR family; step up to size 400 or 600, or down to 200, according to the flow curve for your demand. The 5 um element (code W) is the right choice when downstream valves, cylinders or instruments need finer filtration than the 40 um standard. The manual drain means an operator opens the drain periodically, which suits attended installations; choose an automatic or differential-pressure drain variant for unattended duty. The embedded square psi gauge is fitted here, and MPa or bar scales plus an external round gauge are alternatives. PT is the standard thread; G (BSPP) and NPT are catalogue options to order. No mounting bracket is included with this code.
Because flow is published as curves and not a single rated number, 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 flow for this series as curves, not as a single rated figure, so we do not quote a number. Send us your application details and we will confirm the flow figures from the datasheet on request.
The M in the code selects a manual drain on the bowl: condensate is released by opening the drain by hand at intervals. It suits attended installations; automatic (A) and differential-pressure (blank) drain variants are available in the same series for unattended duty.
