The AirTAC GFR300C10MF2WK 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 GFR300C10MF2WK is an AirTAC GFR300 filter regulator: filtration and pressure regulation combined in a single body, with no lubricator. This configuration is sized for 3/8 in ports with PT thread (the standard; G and NPT are order options), filters to 5 um for cleaner air than the standard 40 um element, and uses a manual drain, so the bowl is emptied by opening the drain valve during checks rather than automatically. The regulator is the standard type with a 0.05-0.9 MPa (7-130 psi) setting range, a square pressure gauge reading in psi is fitted, and a reverse/check valve is built in to hold downstream pressure if the supply drops. A mounting bracket is included.
This is a genuine AirTAC part from the G-series range, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options for drain type, filter grade, gauge style and scale, thread and bracket. Flow figures are published as curves rather than a single rating, so we confirm the datasheet and sizing 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.

Feeding the pneumatic clamps and tool-change cylinders of a CNC machining centre: the 5 um element protects tight-tolerance valves from particulate and water, while the regulator holds a steady clamp pressure and the check valve holds it if shop air dips.
Supplying the air cylinders that push, divert and stop packs on a conveyor line: filtered, regulated air at a set pressure keeps the divert gates acting consistently through the shift, with the psi gauge giving operators a visible setpoint.
Air prep for bench-top test rigs and lab automation using small pneumatic actuators: fine 5 um filtration suits sensitive instrument valves, and the manual drain suits rigs that are checked and maintained as part of each test routine.
Choose the size and port step against the air your application actually consumes: this unit is size 300 with a 3/8 in PT port, and larger sizes carry larger ports and more flow. Because flow is published as curves and not as a single rated figure, ask us to confirm sizing against your consumption before ordering. On this configuration the choices are already made: 5 um filtration (the W grade, one step finer than the 40 um standard), a manual drain (simple and low-cost, but the bowl must be drained by hand - choose automatic or differential-pressure drain codes if you cannot schedule that), a square gauge on the psi scale, a built-in check valve, and an included bracket. If you need a different thread, G (BSPP) and NPT are catalogue options to order as a specification.
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 series as curves, not as a single rated figure, so we do not quote a number here. Tell us your working pressure and air consumption and we will confirm the flow from the datasheet and check the sizing for your application before you order.
The W code in the model selects the optional 5 um element, one step finer than the 40 um standard, for applications with sensitive downstream valves or instruments. The M code selects a manual drain: you open the drain valve to empty the bowl during routine checks, rather than relying on an automatic or differential-pressure drain. If unattended draining matters, ask us about the automatic-drain variant of the same series.
