The AirTAC GFR30015AF2WGK AirTAC Filter Regulator G1/2, 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 automatic 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 GFR30015AF2WGK is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 300 unit is built with a G1/2 (BSPP) port, a 5 um filter element for finer filtration than the standard 40 um grade, an automatic drain that ejects collected condensate without manual attention, an embedded square gauge reading in psi, and a reverse/check valve that holds downstream pressure when the supply is lost. The mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjustment range for this configuration is 0.15-0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um elements, gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so we confirm the datasheet and sizing 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 tool-change clamps and pneumatic actuators on a CNC machining centre, where the 5 um element protects close-tolerance valves and the check valve holds clamp pressure during a supply dip.
Sits at the drop of a carton-sealing or case-erecting station on a packaging conveyor, delivering stable regulated pressure to the flap-fold and taping cylinders while the automatic drain clears condensate without operator rounds.
Prepares the air feed to spray guns in an automotive refinish booth: the 5 um element strips water and particulate that would otherwise blemish the finish, and the regulator holds a steady gun pressure for consistent coverage.
Start with the port and size: this unit steps up to 1/2 inch in the size 300 body, so match it against the air demand of the circuit it feeds - if your consumption sits near the top of the size 300 curve, move to size 400. Next, choose the drain: automatic (fitted here) suits unmanned or hard-to-reach installations, manual suits attended stations, and the differential-pressure default drains only when the element loading justifies it. Filter grade is your other main choice: 40 um is the standard element for general plant air, while the 5 um element fitted here protects finer components such as precision valves and cylinders. Gauge scale (MPa, psi or bar), thread (PT standard, G or NPT to order) and the included bracket complete the configuration. Because flow is published as curves rather than 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves, not as a single rated figure, so we do not quote one number. Send us your line pressure and the air consumption of the equipment you are feeding, and we will confirm the correct size and the datasheet flow figures for your application on request.
The automatic drain ejects collected condensate by itself, which suits unmanned cells, elevated mounts or any bowl that is awkward to reach. The alternatives in the GFR range are the differential-pressure drain (default, drains only under element loading) and the manual drain (drains when an operator opens it). Note that the automatic and differential-pressure versions carry a 0.15-0.9 MPa (20-130 psi) regulation range, while the manual-drain version widens this to 0.05-0.9 MPa (7-130 psi).
