The AirTAC GFR300C15AJF2TK AirTAC Filter Regulator NPT1/2 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 GFR300C15AJF2TK is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built for a 1/2 in NPT port, with an automatic drain, a 40 um filter element, an embedded square gauge reading in psi, a fitted reverse (check) valve, a standard regulator and no mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the regulating range is 0.15-0.9 MPa (20-130 psi), and the working temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and with choices of drain type, 40 um or 5 um filtration, gauge scale, and PT, G or NPT thread. Flow figures are published as curves rather than a single rating, so ask us and we will 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.

Filtering and regulating the compressed air feeding clamps, tool changers and blow-off nozzles on a CNC machining line, with the automatic drain handling condensate from humid shop air.
Supplying clean, regulated air to pick-and-place cylinders and sealing jaws on a packaging conveyor, where the 40 um element protects valve spools from water and debris.
A filter regulator at a point-of-use drop in an assembly plant, setting a stable working pressure for air cylinders and hand-held air tools while the psi gauge gives operators a local reading.
Size and port set the flow path: this unit is a size 300 with a 1/2 in NPT port. If your air demand is higher, step up to size 400 or 600; if lower, size 200 may be enough - ask us to check the flow curves against your consumption before ordering. Drain choice matters: automatic drains condensate without attention, manual needs periodic draining, and the differential-pressure default drains only when the pressure drop is high enough. Filter grade is 40 um as standard; specify code W for 5 um where finer particulate removal is needed. The embedded square gauge reads psi here; MPa and bar scales are available. Thread is NPT on this unit; PT is the AirTAC standard and G (BSPP) is an order option. A bracket can be included, but this configuration omits it. Flow is published as curves, not a single rating, so confirm sizing with us before ordering.
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 series is published in the AirTAC catalogue as curves rather than as a single rated figure, so we do not quote a number here. Send us your air consumption and working pressure and we will confirm the correct size from the datasheet on request.
This configuration carries code A, an automatic drain that expels collected condensate without manual attention. The GFR family is also available with manual drain (code M) or the differential-pressure default, so you can match the drainage style to how the unit will be maintained.
