The AirTAC GFR Filter Regulator GFR300C10MF1W 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.
This GFR300C10MF1W is an AirTAC G-series filter regulator specified with the W option: a 5 um filter element instead of the 40 um standard, giving finer particulate removal along with pressure regulation in one body. It is a size 300 unit with a 3/8 in G (BSPP) port, manual-drain polycarbonate bowl (no lubricator) and an embedded square gauge on the MPa scale. Manual drain gives a 0.05-0.9 MPa (7-130 psi) regulating range; maximum inlet is 1.0 MPa (145 psi) and the medium is compressed air at -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The G-series filter regulator family spans sizes 200 to 600 with automatic, manual or differential-pressure drains, 40 um or 5 um elements, an optional check valve, square or external round gauges in MPa, psi or bar, and PT (standard), G or NPT threads. Because flow is published as curves rather than a single rated figure, ask us to confirm datasheet and sizing 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.

Conditions the air feeding lab bench apparatus and pneumatic test rigs, where the 5 um element keeps fine particles out of sensitive instruments downstream of the regulator.
Filter-regulates the air to spray guns in a finishing booth, so the 5 um element traps finer contamination before air meets coating material at the gun.
Supplies regulated air to the tool-change clamping circuit and chip-blow nozzles on a CNC machining centre, with 5 um filtration protecting the machine's pneumatic valves.
Pick this W-coded unit when the equipment downstream of the regulator is sensitive to fine particles - the 5 um element filters tighter than the 40 um standard. The rest of the decode: size 300 with 3/8 in G port, manual drain for the widest 0.05-0.9 MPa (7-130 psi) regulating range, embedded square MPa gauge. Consider whether 5 um is actually needed - for rough tool circuits the 40 um standard code costs less and flows through a coarser element. Other catalogue choices include automatic or differential-pressure drains, psi or bar gauge scales with an optional round external gauge, PT (the series standard) or NPT threads, and bracketless J codes.
Before ordering, let us read the size 300 flow curve with you: the series has no single rated flow figure, so we confirm the datasheet against your application on request.
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.
We cannot quote a single rated flow because AirTAC publishes G-series performance as flow curves, not one figure. Share your line pressure and required consumption and we will confirm the size 300 sizing from the datasheet on request before you order.
It depends on what the air feeds. The 40 um standard element suits general tool and cylinder circuits; choose this W code (5 um) when downstream valves, guns or instruments need finer filtration. Both grades are catalogue options on the same size 300 body, so you can order either.
