The AirTAC GFR300C10AC2TK AirTAC Filter Regulator NPT3/8 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 GFR300C10AC2TK is a size-300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration has 3/8 in NPT ports, a 40 um standard filter element, an automatic drain that ejects collected condensate without manual attention, a round pressure gauge reading in psi, a reverse/check valve fitted, and the mounting bracket included. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi), and the unit operates from -5 to 70 C in non-freezing conditions. The polycarbonate bowl suits the size-300 frame.
This is a genuine AirTAC part. The GFR filter-regulator family is available in sizes 200, 300, 400 and 600 with a choice of ports and threads (PT standard, with G and NPT as order options), drain types (differential-pressure, automatic or manual), a 5 um optional filter element (code W), gauge styles and scales, and a low-pressure regulator type. Flow figures for this series are published as curves rather than a single rating, so ask us and we will confirm the datasheet 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.

Point-of-use conditioning for a machining center's pneumatic circuits: the filter stage strips water and swarf-laden particulate before it reaches tool-clamp and tool-change cylinders, while the regulator holds a steady supply pressure so clamping sequences repeat predictably through the shift.
Mounted at the drop feeding a bottling line's filler and capper actuators, the unit keeps condensate out of the valve manifold and holds the set pressure the cylinder timing was tuned to; the automatic drain copes with the moisture load of a continuously running compressed-air ring main.
Regulated, filtered air for the diverters, stop gates and pusher cylinders along a sortation conveyor line. The reverse/check valve holds the downstream circuit if the upstream supply dips, and the psi gauge gives maintenance staff a visible setpoint at the machine.
Start with the port step: this unit is size 300 with 3/8 in NPT ports, one step up from the 1/4 in size-200 frame - pick the size whose flow curve covers your demand rather than upsizing blindly. Choose the drain to match access: automatic (this unit) suits installations that are not checked daily; manual suits attended points; the differential-pressure default drains only when the pressure drop warrants it. The 40 um element is the standard grade; specify the 5 um W option where finer particulate removal matters. Gauge style and scale are decodable choices - this configuration carries a round gauge reading psi, while the embedded square gauge with MPa, psi or bar scales is the alternative. Thread is PT as the catalogue standard with G (BSPP) and NPT orderable; the bracket is included on this code, and the K suffix means a reverse/check valve is fitted. Because flow is published as curves and not a single rated number, 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 flow for the GFR300 series as performance curves rather than a single rated figure, so we do not quote one number. Tell us your working pressure and air demand and we will confirm the datasheet curve and sizing for your application on request before you order.
The A in the code specifies an automatic drain, which ejects collected condensate on its own - the right choice where the unit is not checked daily. The catalogue alternatives are the differential-pressure drain (the default, which drains only when the element loading warrants it) and the manual M drain for attended installations. Note that the regulator adjustment range depends on the drain: automatic and differential-pressure drains give 0.15-0.9 MPa (20-130 psi), while the manual drain allows 0.05-0.9 MPa (7-130 psi).
