The AirTAC GFR300C15AJF2WGK AirTAC Filter Regulator G1/2, 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 GFR300C15AJF2WGK is an AirTAC GFR300 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This configuration is built around a G1/2 (BSPP) port on the size 300 frame, with a 5 um filter element (code W), an automatic drain that ejects collected condensate without manual attention, a standard regulator adjustable from 0.15-0.9 MPa (20-130 psi), an embedded square gauge scaled in psi, and a reverse/check valve fitted. The bowl on this size is polycarbonate (PC), max inlet pressure is 1.0 MPa (145 psi), operating temperature is -5 to 70 C (non-freezing), and no mounting bracket is included (code J).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and can be ordered with manual, automatic or differential-pressure drains, 40 um or 5 um elements, square or round gauges scaled in MPa, psi or bar, G (BSPP) or NPT threads in place of the PT standard, and with or without a bracket. 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.

Feed carton sealers and case erectors on a packaging line: the 5 um element keeps water and fines out of directional valves while the regulator holds a steady working pressure for consistent cylinder strokes.
Supply pop-up diverters, gate stoppers and pneumatic clamps along a conveyor system; the automatic drain handles condensate on continuously running lines without an operator stopping to bleed the bowl.
Provide clean, regulated air to test rigs and lab instrumentation benches, where the 5 um grade and a psi-scaled square gauge make set-and-check adjustments straightforward.
Size and port set the flow path: the 300 frame with a 1/2 inch port sits mid-range in the GFR line (200/300/400/600), so step up or down according to the air demand of the circuit - we can check the published flow curves against your requirement before you order. Drain choice matters: automatic (this unit) suits unattended duty, manual suits periodic inspection, and differential-pressure drain is the catalogue default. Filter grade is 40 um standard or 5 um (W, this unit) for finer protection. Gauges are embedded square as standard with an optional external round gauge in MPa, psi or bar scales. Thread here is G (BSPP); PT is the standard and G/NPT are catalogue options to order. This unit is supplied without a mounting bracket (code J), and the K code adds a reverse/check valve.
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.
Flow for the GFR300 is published as curves, not as a single rated figure, so we do not quote a number here. Send us your application's air demand and we will confirm the sizing from the AirTAC datasheet on request.
The W code in this model specifies the finer 5 um element; the catalogue standard is 40 um. Choose 5 um where downstream valves, cylinders or instruments need finer protection against water and particulate. Both grades are available across the GFR range, and this unit also carries an automatic drain, a psi-scaled square gauge and a reverse/check valve (K).
