The AirTAC GFR300C15JF2WTK 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 GFR300C15JF2WTK is an AirTAC GFR300 filter regulator: one body that removes water and particulate from compressed air and then regulates the downstream pressure. This configuration is a size 300 unit with 1/2 in NPT ports, a 5 um filter element (code W), a differential-pressure drain that clears the bowl automatically as inlet pressure falls, an embedded square gauge reading in psi, and a built-in reverse/check valve that holds the downstream setting if upstream pressure is lost. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The bowl on this size is polycarbonate; only the 600 size uses an aluminium alloy bowl. No mounting bracket is fitted with this code.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filtration, an embedded square gauge or an optional external round gauge in MPa, psi or bar scales, and PT (standard), G or NPT threads. Flow for the series 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.

Feeds clean, regulated air to the clamping cylinders and vise actuators on a machining centre, with the 5 um element protecting directional valves from condensate and fine swarf carryover.
Supplies filtered, regulated air to the diverter and stopper cylinders along a carton conveyor, while the reverse/check valve holds the downstream circuit if supply pressure dips mid-run.
Powers gate and filler actuators on a bottling line, where the regulator keeps actuator movement consistent and the differential-pressure drain clears bowl condensate between shifts without manual attention.
Choose the size by port and demand: this unit is size 300 with a 1/2 in NPT port; step up to 400 or 600, or down to 200, as your circuit's air demand changes - we can check the published flow curves against your consumption. Drain: differential-pressure (fitted here) empties the bowl automatically as pressure falls; automatic (A) and manual (M) are the alternatives. Filter grade: 40 um is standard, while the W code on this unit selects the finer 5 um element for better protection of downstream valves and cylinders. The square gauge reads psi; MPa and bar scales, and an external round gauge, are catalogue options. Thread: PT is the standard, with G and NPT as order options - this code is NPT. Bracket: not fitted (J). Because flow is published as curves and not a single rating, send us your application details and we will confirm sizing 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 rather than a single rated figure, so we do not quote a number here. Send us your port size, upstream pressure and air consumption, and we will confirm the flow and the full datasheet for this unit on request.
W selects the 5 um filter element instead of the 40 um standard, giving finer protection for downstream valves and cylinders. The K code fits a reverse/check valve, which holds the regulated downstream pressure if the upstream supply is interrupted. Both are standard catalogue options on the GFR family.
