The AirTAC GFR300C10F2WGK 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 GFR300C10F2WGK is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your set point in one body. This size 300 unit is threaded G3/8 (BSPP), carries the fine 5 um filter element (code W), drains condensate by differential pressure, and is fitted with a round pressure gauge reading in psi plus a reverse/check valve (code K) that holds upstream pressure in the bowl side. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi) with this drain type, and max inlet pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C, non-freezing. The polycarbonate bowl suits this size, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of 40 um standard or 5 um fine filtration, differential-pressure, automatic or manual drains, gauge shape and scale options, and G (BSPP) or NPT threads as order options alongside the PT standard. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Feeding cleaned, pressure-regulated air to the clamping cylinders and tool-change actuators on a machining centre, with the 5 um element guarding fine pilot valves and the check valve holding the bowl-side supply if the main line drops.
Conditioning the air supply to vacuum generators and gripper cylinders on a carton or bottle packaging conveyor, where the regulator keeps actuator speed consistent and the differential-pressure drain clears condensate without stopping the line.
Supplying regulated air to spray guns and air-assisted applicators at a finishing station, where water and 5 um-level particulate removal help protect the finish and the psi gauge gives operators a direct reading at the drop.
Step through the decodable choices: pick the size (200/300/400/600) and port so the unit matches your line size and expected flow - going one size up costs little and reduces pressure drop. Choose the drain: differential-pressure (this model, automatic on pressure differential), fully automatic, or manual. Choose the filter grade: 40 um standard for general air prep, 5 um (code W, as here) for finer protection of valves and cylinders. Select gauge shape and scale - this unit has a round gauge in psi; embedded square gauges and MPa/bar scales are alternatives. Thread: PT is the standard; G (BSPP, as this code) and NPT are catalogue options to order. A bracket is included on this configuration. Flow is published as curves, not a single rating, so send us your application details and we will confirm 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 GFR flow as curves rather than a single rated figure, so there is no one rated flow number we can honestly quote. Tell us your line pressure, set pressure and the cylinders or equipment you are feeding, and we will confirm the sizing from the datasheet flow curves before you order.
W is the filter grade: 5 um fine filtration instead of the 40 um standard element, worth choosing when the downstream valves or tools are sensitive to finer particles. K means a reverse/check valve is fitted, which helps hold pressure on the bowl side if the upstream supply is interrupted. Both are factory-fitted on this unit, along with a round psi gauge, G3/8 thread and differential-pressure drain.
