The AirTAC GFR300C15MJC2WT 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 GFR300C15MJC2WT is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in one compact body. This configuration is built for 1/2 in NPT ports, filters to 5 um for cleaner air than the standard 40 um element, and uses a manual drain you operate by hand to release collected condensate. A round gauge reading in psi is fitted so operators can see and verify the regulated pressure, and the standard regulator covers 0.05-0.9 MPa (7-130 psi). Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. No mounting bracket is included and no reverse (check) valve is fitted.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options include automatic, manual or differential-pressure drains, 40 um or 5 um filtration, square or round gauges in MPa, psi or bar scales, G (BSPP) or NPT threads alongside the PT standard, and bracket choices. Rated flow is published as curves rather than a single figure, so ask us to confirm flow and datasheet details for your application.

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.

Supplying clean, regulated air to press cylinders: the 5 um element helps keep water and particulate away from valve seals, while the regulator holds a steady setpoint stroke after stroke.
Feeding stoppers, clamps and diverters on a packaging conveyor; the round psi gauge lets operators check setpoints at a glance and the manual drain is emptied during routine shift checks.
Supplying spray guns in a paint or coating booth, where 5 um filtration helps keep water and debris out of the finish and the regulator pins the atomizing pressure at the setpoint.
Step through sizes 200, 300, 400 and 600 to match the port and flow your line needs; this unit sits at size 300 with 1/2 in NPT ports. Choose the drain to suit access: manual (this unit) suits attended installations, automatic suits unattended duty, and differential-pressure is the catalogue default. Pick 40 um for general protection or 5 um (this unit, code W) where downstream equipment needs cleaner air. Gauges come as an embedded square gauge or an external round gauge in MPa, psi or bar scales; this unit carries a round psi gauge. PT is the standard thread, with G (BSPP) and NPT as order options, and brackets are optional. Flow is published as curves, not a single rating, so send us your flow requirement and we will confirm sizing against the datasheet 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 as curves rather than a single rated figure, so we do not quote one number. Send us your required flow and line conditions and we will confirm the sizing from the datasheet on request.
The 5 um element (code W) filters more finely than the 40 um standard, which suits valves, cylinders and other sensitive downstream equipment. The manual drain means you open it by hand to release collected water - simple and reliable where the unit is checked regularly. Automatic and differential-pressure drains are available on other configurations.
