The AirTAC GFR30015MF1WT AirTAC Filter Regulator NPT1/2, 5 um is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1/2" ports, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR30015MF1WT is a 300-size filter regulator that removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration is built with a 1/2 in NPT port, a 5 um filter element for finer dirt capture than the standard 40 um grade, a manual drain you operate by hand to empty the bowl, and an embedded square pressure gauge scaled in MPa. The standard regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi) with this manual-drain version, and maximum inlet pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C, non-freezing. The PC (polycarbonate) bowl is fitted with a mounting bracket included.
This is a genuine AirTAC part. The GFR family is available in 200, 300, 400 and 600 sizes with port options from 1/8 to 1 inch, PT as the standard thread and G or NPT as order options, plus choices of drain type, filter grade, gauge style and scale, and bracket. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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 0.05 - 0.9 MPa (7 - 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 a machining centre's pneumatic tool-change and clamping circuits, with the 5 um element protecting fine valves from particulate and the manual drain emptied during scheduled maintenance.
Sits at the drop point of a cartoning or wrapping line, filtering condensed water from the ring main and holding a set pressure for the cylinders that fold, seal and push product along the conveyor.
Conditions the air feeding spray guns and air-assisted applicators, where the 5 um grade limits dirt in the finish and the regulator holds a steady gun pressure set on the MPa gauge.
Size and port drive the choice: the 300 size with its 1/2 in NPT port suits lines that need more flow than the 200 size, and the next step up is the 400 size - match the step to your required flow, which we confirm from the datasheet curves before you order. This unit pairs a manual drain (simple hand-operated bowl emptying, and it widens the regulation range to 0.05-0.9 MPa) with a 5 um element where finer filtration than the standard 40 um grade matters. The embedded square gauge reads in MPa; an external round gauge with MPa, psi or bar scale is optional. NPT is ordered as the thread option, and the bracket is included. Because flow is published as curves, not a single rating, 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 series as curves, not as a single rated number, so we do not quote a figure here. Tell us your application and we will confirm the flow and sizing from the datasheet on request.
The M in the code selects a manual drain: you empty the bowl by hand on a schedule, and this drain type widens the regulator adjustment range to 0.05-0.9 MPa (7-130 psi). The W selects the 5 um element instead of the standard 40 um grade, for finer particulate capture. Automatic and differential-pressure drains are available on other GFR300 codes.
