The AirTAC GFR300C15AC2TK AirTAC Filter Regulator NPT1/2 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 GFR300C15AC2TK is an AirTAC GFR300 filter regulator: a single body that removes water and particulate from compressed air and then regulates downstream pressure. This configuration is a size 300 unit with a 1/2 in NPT port, a 40 um standard filter element, and an automatic drain that discharges collected condensate from the bowl without manual attention. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the C2 code adds an external round gauge with a psi scale for direct set-point reading. A reverse/check valve (K) is fitted to hold downstream pressure, and the mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, thread options PT (standard), G and NPT, drain choices of differential-pressure, automatic or manual, and an optional 5 um element (code W). 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.

Feed clean, regulated air to the cylinders and grippers of a cartoning or wrapping line, with the automatic drain handling condensate between shifts.
Regulate the supply to pop-up diverters and stopper cylinders on a distribution conveyor so gate timing stays consistent through the day.
Hold a stable clamping pressure on a CNC fixture with the check valve maintaining downstream pressure if the main supply dips during a cycle.
Size 300 with a 1/2 in NPT port suits lines whose air demand sits in the middle of the GFR range; step up to size 400 or 600 for higher flow, or down to size 200 for compact circuits. The automatic drain on this unit is the right choice where the bowl is hard to reach or the line runs unattended; manual drain suits supervised installations, and differential-pressure drain is the catalogue default. The fitted round gauge reads in psi; square embedded gauges and MPa or bar scales are available if you prefer. NPT is an order option alongside the PT standard and G thread, so confirm the thread family matches your piping. A bracket is included for panel or surface fixing. Because flow is published as curves and not a single rating, send us your demand figures 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 we do not quote a l/min or SCFM number. Tell us your line demand and working pressure and we will confirm the sizing from the datasheet on request before you order.
The A in the code means the bowl drains collected condensate automatically, which suits unattended or hard-to-reach installations. The same GFR300 size is also available with manual drain or the differential-pressure default, and with a 5 um element (code W) if finer filtration is needed - just ask for the alternative code.
