The AirTAC GFR300C15MJF2WGK AirTAC Filter Regulator G1/2, 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 GFR300C15MJF2WGK is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This unit is built on the GFR300 size with a G1/2 (1/2 in) port, a 5 um filter element, and a manual drain on the metal bowl, so condensate is released by hand rather than automatically. Regulation is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and an embedded square gauge reading in psi is fitted so setpoints can be checked directly at the unit. A reverse (check) valve is fitted, and the unit is supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR300 sits in the middle of the GFR range, which runs from size 200 to 600 with ports from 1/8 in to 1 in, and is offered with a choice of drain type, 40 um or 5 um filtration, gauge scale, thread (PT standard, G and NPT to order) and bracket. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing figures 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.

Point-of-use air preparation for a CNC machining centre: the 5 um element protects solenoid valves and tool-changer cylinders from particles and water, while the regulator holds a steady clamp pressure read on the psi gauge.
Filtered, regulated air for carton sealers, case erectors and stretch-wrap stations on a packaging line, with the fitted psi gauge letting line technicians verify setpoints without extra tooling.
Air preparation upstream of weld-clamp actuators in a robotic body shop, where the fitted reverse valve serves circuits that must not back-feed toward the supply side.
Choose the size and port against the air your application actually uses: GFR300 with a G1/2 port is the mid-range step in a family that runs from 1/8 in to 1 in, and the right step depends on flow demand, which is published as curves rather than one rated figure. On this unit the choices are already set: 5 um filtration instead of the standard 40 um, a manual drain instead of automatic or differential-pressure, a square gauge reading psi, G thread instead of PT standard or NPT, and no mounting bracket. If any of those should differ, the same GFR300 body is available with the alternative options. Because flow is not published as a single number, 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 a number here. Send us your application details and we will confirm the flow and sizing data from the datasheet on request.
This unit has a manual drain: condensate collected in the metal bowl is released by opening the drain by hand. It suits points that are visited routinely during operation; if the installation runs unattended, the same GFR300 body is available with an automatic or differential-pressure drain instead.
