The AirTAC GFR30015F2WK AirTAC Filter Regulator PT1/2, 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 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 GFR30015F2WK is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This configuration is built with 1/2 in PT ports, a 5 um filter element (code W), a differential-pressure drain, a standard regulator adjustable from 0.15-0.9 MPa (20-130 psi), an embedded square gauge scaled in psi, and a reverse/check valve (code K). A mounting bracket is included, and the polycarbonate bowl is the catalogue material for the 300 size.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, PT (standard), G or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um elements, and gauge options. Maximum inlet pressure is 1.0 MPa (145 psi) and working temperature is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing 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.

Feeding spray guns and air-assisted applicators on a finishing line, where clean, dry air at a set pressure keeps atomisation consistent; the 5 um element and psi gauge suit booth-side setup.
Regulating supply to pick-and-place and carton-sealing cylinders along a packaging conveyor, with the check valve holding downstream pressure if the upstream supply dips.
Supplying filtered, regulated air to pneumatic clamps and tool-changer actuators on a machining centre; the included bracket allows mounting beside the machine's air drop.
Size and port step up with flow demand: this 300-size unit carries 1/2 in PT threads. Choose the drain to match service - differential-pressure (this unit) bleeds as pressure drops, automatic (A) suits unattended duty, manual (M) for infrequent bleeding. The 5 um element (W) gives finer particulate removal than the 40 um standard grade. The square gauge here reads psi; MPa and bar scales, and an external round gauge, are options. PT is the standard thread, with G (BSPP) and NPT available to order, and a bracket is included. Flow is published as curves, not a single rating - send us your flow and pressure requirements 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. The reflux valve permits reverse flow 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. Tell us your flow and working pressure and we will confirm sizing from the datasheet on request.
The W code specifies the 5 um element instead of the 40 um standard, for finer particulate removal. The K code adds a reverse/check valve so downstream pressure is held if the supply is lost. Both are catalogue options on the GFR300.
