The AirTAC GFR30015AC2W 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 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 GFR300-15 combines water and particulate filtration with pressure regulation in a single body, so one PT1/2-port unit both cleans the compressed air and sets a stable downstream pressure. This configuration carries the W-grade 5 um filter element for finer particle removal than the standard 40 um element, an automatic drain that expels collected condensate without manual attention, a round pressure gauge reading in psi, and a mounting bracket in the box. Maximum inlet pressure is 1.0 MPa (145 psi) and the standard regulator covers a setting range of 0.15-0.9 MPa (20-130 psi); operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the GFR300 series. The GFR line is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, embedded square or optional external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application before ordering.

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 clean, pressure-set air to the tool-clamp and actuation circuits of a CNC machining centre, with the 5 um element guarding spool valves from fine particles and the automatic drain handling condensate on a machine that runs unattended shifts.
Sits upstream of the directional valves driving carton-forming and case-sealing cylinders on a packaging conveyor line, holding the set pressure steady through the machine cycle while the PT1/2 port matches the line's main drop.
Conditions the supply feeding pneumatic actuators on lab sample-handling and testing equipment, where the 5 um grade and a psi-reading round gauge give technicians fine-particle protection and a familiar pressure readout at the panel.
Start with the port and body size: the GFR300 with its PT1/2 connection sits in the middle of the 200/300/400/600 range, so step up to size 400 or 600 if your line's air demand points higher, or down to 200 if the circuit is small. Choose the drain to match how the unit will be tended: automatic drain (this model) suits installations that are not checked daily, manual drain suits attended stations, and differential-pressure drain is the catalogue default. Pick the 5 um W element where downstream equipment needs finer air than the standard 40 um element provides. Gauge scale (MPa, psi or bar) and PT versus G or NPT thread are order-time choices, and a bracket is included with this unit. Flow for this family is published as curves, not a single rating, so send us your application details 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 GFR series as curves rather than a single rated figure, so there is no one rated-flow number we can honestly quote. Send us your application's air demand and we will confirm the relevant datasheet curve figures for the GFR300 at PT1/2 before you order.
The W code on this model specifies the 5 um filter element instead of the standard 40 um element, which suits downstream equipment that is sensitive to finer particles. The A code specifies an automatic drain, which ejects collected condensate on its own instead of waiting for someone to open a manual drain - a practical choice for units mounted in less accessible spots.
