The AirTAC GFR30015C1WT AirTAC Filter Regulator 1/2 in NPT, 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 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 GFR30015C1WT is an AirTAC GFR300 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is built with 1/2 in NPT ports, a 5 um filter element (code W), a differential-pressure drain and a round pressure gauge reading in MPa. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the unit takes a maximum inlet pressure of 1.0 MPa (145 psi). The polycarbonate bowl suits non-freezing compressed air from -5 to 70 C, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and with choices of drain type, filter grade (40 um standard or 5 um), gauge style and scale, thread (PT standard, with G or NPT as order options) and bracket. Flow for the GFR300 is published as curves rather than a single rated figure, so we confirm the datasheet and flow figures for your application 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 0.15 - 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 filtered, regulated air to the workholding clamps and tool-change cylinders on a CNC machining centre, with the 5 um element protecting downstream valves from particulate carried in the shop air.
Supplies clean, pressure-controlled air to carton sealers, case packers and pick-and-place cylinders on a packaging conveyor, where the regulator holds a stable setting as line demand changes through the shift.
Conditions the air feeding spray guns and air-assisted applicators on an automotive paint line, using the 5 um grade to strip water and fine particles before the regulated supply reaches the booth.
Size the unit by the port and air demand of your line: size 300 sits between the smaller 200 and the larger 400, each step giving a bigger port and more flow - ask us to confirm the flow curve against your demand before ordering. This unit carries the 5 um element (code W); the 40 um standard grade is available if finer filtration is not required. The drain here is differential-pressure, which bleeds the bowl automatically as flow varies; automatic (A) and manual (M) drains are the alternatives. The round gauge reads in MPa, with psi and bar scales, an embedded square gauge or a no-gauge build as options. PT is the standard thread, and G or NPT versions are order options; a bracket is included with this size.
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 number, so we do not quote a figure here. Send us your line pressure and air demand and we will confirm the flow from the datasheet for this exact configuration before you order.
W is the filter-grade code: this unit carries a 5 um element instead of the 40 um standard. The 5 um element gives finer particulate removal ahead of the regulator; choose the 40 um standard grade if your application does not need the finer filtration.
