The AirTAC GFR300C10F2WG 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 GFR300C10F2WG is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration is built for a G3/8 (BSPP) port, carries the finer 5 um filter element, drains accumulated condensate by differential pressure, and is fitted with an embedded square gauge reading in psi. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, the bowl is polycarbonate, and a mounting bracket is included.
It is a genuine AirTAC part from a family offered in sizes 200, 300, 400 and 600, with port options from 1/8 to 1 inch, manual and automatic drain alternatives, a 40 um standard filtration option, gauge scale choices and G or NPT thread variants. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet 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.

Placed ahead of the machine's directional valves, it strips water and fine particles from the shop-air feed and holds a steady setting for the tool-change and clamping circuits, with the psi gauge giving the setter a direct readout.
Feeding the cylinders and grippers on a carton-sealing or filling conveyor, it keeps the supply clean and the pressure at the setting the line was tuned to, while the differential-pressure drain bleeds off collected condensate.
On a test bench or lab manifold running air-driven apparatus, the 5 um element helps protect sensitive instruments from water and fine particulate, and the square psi gauge supports repeatable daily setups.
Size 300 with a 3/8 in port is the middle step of the GFR range; step down to size 200 or up to 400 or 600 as your circuit's demand changes - since flow is published as curves rather than a single rating, ask us to confirm the sizing against your application before ordering. Drain on this code is the differential-pressure type, with automatic and manual drain versions available as separate codes. The 5 um element is the finer alternative to the standard 40 um grade; the embedded square gauge reads psi, and MPa or bar scales are orderable. Thread here is G (BSPP), with PT and NPT variants to order, and a mounting bracket is included.
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 GFR-series flow as curves rather than a single rated figure, so no one number applies to this model. Send us your operating pressure and air demand and we will confirm the sizing from the datasheet on request.
The W in the code orders the finer 5 um element instead of the standard 40 um grade, for circuits feeding cleaner-air-sensitive equipment. The blank drain position is the differential-pressure type, which discharges accumulated condensate as flow passes the unit; manual and automatic drain versions are separate order codes.
