The AirTAC GFR300C15JF2WT AirTAC Filter Regulator NPT1/2, 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 GFR300C15JF2WT is a GFR300 filter regulator: one body that removes water and particulate from compressed air and then regulates the downstream pressure. This configuration is sized 300 with 1/2 in NPT ports, filters to 5 um for cleaner air than the standard 40 um element, drains condensate by differential pressure, and carries the embedded square gauge reading in psi. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, maximum inlet pressure is 1.0 MPa (145 psi), the size 300 bowl is polycarbonate, and no mounting bracket or check valve is fitted. Working temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, differential-pressure, automatic or manual drains, 40 um or 5 um elements, MPa, psi or bar gauge scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing and any datasheet figure 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.

Feeding carton sealers, case wrappers and label-head cylinders on a packaging line with air that is both dry of condensate and held at the pressure the machine builder specifies.
Supplying tool-clamp, chip-clearing and coolant-door actuators on a machining centre, where the 5 um element protects fine pilot valves from particulate carryover.
Regulating air to gripper cylinders and vacuum ejectors on a conveyor pick-and-place station, with the psi gauge giving operators a direct reading at the station.
Size and port set the air capacity: the GFR300 steps up from GFR200 with a 1/2 in port, so match the size to the flow your line needs - we can check the published curves against your demand. Choose the drain: differential-pressure (as on this unit), automatic, or manual; with the differential-pressure drain the regulation range is 0.15-0.9 MPa (20-130 psi), while the manual-drain variant widens the low end to 0.05 MPa. Choose the element: 5 um as fitted here, or the standard 40 um. The embedded square gauge is standard and this unit reads in psi; MPa or bar scales and an external round gauge are order options. Thread: PT is the standard, with G and NPT as order options - this unit is NPT. A mounting bracket is optional on the family and is not fitted on this unit. Then the honest routing: flow is published as curves, not a single rating, so ask us to confirm sizing against your application 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.
AirTAC publishes flow for the GFR300 as curves, not as a single rated figure, so we do not quote one number. Send us your line demand and we will confirm from the datasheet whether this 1/2 in size suits your application before you order.
The W code in the model fits the 5 um element, which strips finer particulate than the standard 40 um grade - useful upstream of pilot valves and sensitive actuators. If your equipment tolerates ordinary shop air, the 40 um standard grade is also available in this family; ask us to quote either.
