The AirTAC GFR300C15AJC2W AirTAC Filter Regulator PT1/2, 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 AirTAC GFR300C15AJC2W is a size 300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built with a PT1/2 port, an automatic drain that expels collected condensate without manual attention, a fine 5 um filter element, and a round pressure gauge reading in psi. The standard regulator covers a 0.15-0.9 MPa (20-130 psi) adjustment range, and no mounting bracket is included.
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600, with port options from 1/8 to 1 inch, PT, G or NPT threads, manual, automatic or differential-pressure drains, 40 um or 5 um elements, and a choice of gauge style and scale. Flow figures are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details 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.

Feeding clean, regulated air to the tool-clamp and chip-clearing circuits of a CNC machining centre, where the 5 um element protects precision valves and the psi gauge lets setters dial in clamp pressure.
Conditioning and regulating the air feeding diverter gates, sealing jaws and pusher cylinders on a carton packaging line, with the automatic drain keeping condensate out of the loop during long shifts.
Supplying steady, filtered air to sample-handling actuators and pneumatic pipettes on a lab automation skid, where the fine 5 um grade and a stable regulated pressure protect sensitive motion components.
Choose the size and port step against the air demand of the circuit: this unit is size 300 with a 1/2 inch PT port, one step up from size 200 and below the larger 400 and 600 frames. The 5 um element in this model is the finer of the two published grades (40 um is the standard alternative) - pick 5 um where downstream valves, cylinders or instruments need cleaner air. The automatic drain suits unattended or hard-to-reach installations; manual and differential-pressure drains are available if you prefer operator-controlled or pressure-differential draining. The round psi gauge is one of several gauge styles and scales (MPa, psi, bar). Thread is PT as standard, with G and NPT as order options, and a mounting bracket can be ordered separately. Because flow is published as curves rather than a single rated figure, 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 flow for the GFR300 series as curves, not as a single rated number, so we do not quote a figure here. Tell us your working pressure and air demand and we will confirm the sizing from the datasheet on request.
The code decodes W as the 5 um filter grade (the finer option; 40 um is standard) and A as an automatic drain, which ejects collected condensate on its own instead of requiring manual draining. Both are order choices across the GFR range, along with drain type, gauge style and scale, and thread.
