The AirTAC GFR300C15AF2 AirTAC Filter Regulator 1/2 in PT is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet 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 AirTAC GFR300C15AF2 is a GFR300-series filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This configuration is built around a PT1/2 (1/2 in) port with PT thread, an automatic drain that removes collected condensate without manual attention, a 40 um standard filter element, and an embedded square gauge reading in psi. The standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). The bowl on this 300 size is polycarbonate (PC), and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with a choice of port sizes, PT, G or NPT threads, differential-pressure, automatic or manual drains, a 5 um (code W) filter element option, and gauge scales in MPa, psi or bar. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Fit at the point of use on a factory air drop to feed cylinders and air tools on an assembly line, giving each station its own filtered, regulated supply at a 1/2 in connection.
Place ahead of the clamping circuit in a CNC machining cell so fixtures receive clean, moisture-reduced air held at the set pressure the clamps were designed for.
Install on the supply to sorting and diverting actuators along a packaging conveyor, where the automatic drain keeps condensate out of valves running through wet shifts.
Choose the size and port by the flow your line needs: this unit is size 300 with a 1/2 in PT port. Drain type is a real decision - the automatic drain fitted here handles condensate removal on its own, while manual and differential-pressure drains are available in the family. The 40 um element fitted here is the standard grade; specify code W for 5 um where finer filtration matters. Gauge scale is selectable (this unit reads psi; MPa and bar are options), and PT is the standard thread with G and NPT available to order. A mounting bracket is included. 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR300 flow as curves, not as a single rated number, so we do not quote a figure here. Send us your flow and pressure requirements and we will confirm the datasheet figures and check the sizing for your application.
This unit is supplied with an automatic drain, which expels collected condensate without anyone opening the bowl - useful on lines that run unattended. The GFR300 family is also available with manual or differential-pressure drains if you prefer a different arrangement.
