The AirTAC AirTAC GFR300C15JF2G Filter Regulator G1/2 (40 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 GFR300C15JF2G is a size-300 filter regulator: it removes water and particulate from compressed air and sets downstream pressure in one body. This configuration carries a G1/2 port (G thread; PT is the standard thread form, with G and NPT available as order options), a 40 um standard filter element, a differential-pressure drain in the polycarbonate bowl, and a standard regulator with a 0.15-0.9 MPa (20-130 psi) setting range. The embedded square gauge is fitted with a psi scale, and no mounting bracket or reverse/check valve is included.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch. Options across the family include automatic or manual drains, a 5 um element (code W), alternate gauge scales, and bracket variants. Flow is published as curves rather than a single rated figure, so we confirm the datasheet figures for your application on request.

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.

Point-of-use conditioning ahead of a clamping or stamping cylinder circuit, filtering plant air to 40 um and holding a steady regulated setting so cycle force stays repeatable.
Supplying filtered, regulated air to the stopper, pusher and divert cylinders along a bottling or cartoning conveyor, with the square psi gauge giving operators a local setpoint readout.
Conditioning the air feed to an automatic tool changer and air-blast nozzle on a machining centre, where water and chips in the supply would otherwise foul the clamping mechanism.
Size and port step up together in the GFR family: 200 through 600 cover 1/8 to 1 inch ports, so match the size to the air demand of the circuit - flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering. On this unit the drain is differential-pressure (the default, which bleeds the bowl as inlet-to-outlet differential builds); automatic (A) or manual (M) drains are the other decodable choices. The element is 40 um standard; specify W for 5 um where finer filtration is needed. The gauge here is the embedded square type on a psi scale; MPa and bar scales and an external round gauge are the alternatives. Thread is G on this code, with PT as the standard form and NPT orderable - state the connection you need when ordering. Bracket: this code is supplied without one (J).
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 GFR series as curves rather than a single rated number, so we do not quote one figure. Tell us your line pressure, set pressure and air demand and we will confirm the flow from the datasheet curves for this exact G1/2 unit before you order.
With no drain letter in the code, the bowl uses the differential-pressure drain: it discharges collected condensate automatically as the pressure difference across the filter builds, with no operator action. If you prefer a fully automatic float drain or a manual drain, those are the other decodable options in the family - just specify A or M in the code when ordering.
