The AirTAC GFR300C10ANTK AirTAC Filter Regulator NPT3/8 Auto Drain 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 GFR300C10ANTK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 300-size unit has a 3/8 in NPT port, an automatic drain that ejects collected condensate without manual attention, a 40 um standard filter element, and a reverse/check valve fitted. It comes without a gauge (code N); a gauge can be ordered as an option. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). The bowl at this size is polycarbonate (only size 600 uses aluminium alloy), and the regulation range with automatic drain is 0.15-0.9 MPa (20-130 psi).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, a choice of drain (differential-pressure, automatic or manual), 40 um standard or 5 um (code W) filtration, gauge options, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm flow and other datasheet details 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.

Feeding clean, pressure-controlled air to the clamping and forming cylinders of a pneumatic workbench press, with the automatic drain clearing condensate between shifts.
Supplying filtered and regulated air to the diverters, pushers and sealing cylinders along a carton packaging line, where stable pressure keeps cycle timing consistent.
Conditioning the air feeding grippers and small actuators on lab automation equipment, with the 40 um element protecting downstream valves from water and particulate.
Size and port set the capacity: this unit is size 300 with a 3/8 in NPT thread (PT is the standard thread; G and NPT are order options). Because flow is published as curves rather than a single rating, send us your air demand and we will confirm sizing against the datasheet before you order. Other real choices on this family: drain type - differential-pressure (default), automatic as fitted here, or manual, noting the regulation range differs (0.15-0.9 MPa / 20-130 psi with automatic or differential drain, 0.05-0.9 MPa / 7-130 psi with manual drain); filter grade 40 um standard or 5 um with code W; gauge and scale (MPa, psi or bar) if you want one fitted; and bracket - this configuration includes one.
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 family as curves rather than a single rated figure, so no single number would be honest. Tell us your air demand and line pressure and we will confirm the flow from the datasheet for this exact 300-size, 3/8 in NPT configuration before you order.
The N in the code means no gauge is fitted; a gauge is an available option, and you can choose the scale (MPa, psi or bar). This configuration does include an automatic drain, a 40 um filter element, a reverse/check valve (code K) and a mounting bracket.
