The AirTAC GFR300C10MF2W AirTAC Filter Regulator PT3/8, 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 GFR300C10MF2W is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a PT3/8 port, a fine 5 um filter element, a manual drain bowl, and an embedded square gauge scaled in psi. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), a mounting bracket is included, and no reverse/check valve 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, with a choice of drain type, 40 um or 5 um filtration, gauge style and scale, and PT, G or NPT thread. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application before ordering.

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.

Point-of-use conditioning ahead of the tool-change cylinders and clamps on a CNC machining centre: the 5 um element protects the directional valves from particulate and water, while the regulator holds a steady setting for consistent clamp force.
Conditioning the air feeding stopper, pusher and diverting cylinders on a carton packaging conveyor line, where the manual drain suits a station checked at shift start and the psi gauge lets maintenance verify the line setting at a glance.
Filtered, regulated air for the pneumatic valve stack on a bench-mounted assembly press, keeping water and 5 um-and-larger particles out of the control valves and giving the operator a visible, locked process pressure.
Step through the decodable choices in order. First, size and port: this unit is size 300 with a PT3/8 port; larger sizes carry larger ports and more flow capacity, so match the size step to the air demand of the circuit rather than to the pipe alone. Second, drainage: this unit has a manual drain, which suits positions an operator visits routinely; if the bowl sits where regular draining is impractical, ask about the automatic or differential-pressure drain variants. Third, filtration grade: this unit carries the fine 5 um element (code W); the standard grade is 40 um, so choose 5 um where downstream valves and cylinders need finer protection. Fourth, gauge: the embedded square gauge here reads in psi, with MPa and bar scales and an external round gauge available as options. Thread is PT as standard, with G and NPT as order options, and a mounting bracket is included.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated number, so we do not quote a flow figure here. Send us your application details and we will confirm the 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 flow for the GFR family as curves rather than a single rated figure, so we do not quote a flow number here. Tell us your application - port size, upstream pressure and the downstream demand - and we will confirm the sizing against the manufacturer datasheet on request before you order.
The M in the code GFR300C10MF2W specifies a manual drain bowl: collected water must be drained by hand, which suits positions an operator already visits on a routine schedule. If the unit will sit unattended or in a hard-to-reach spot, ask us about the automatic-drain or differential-pressure-drain variants of the same GFR300 size.
