The AirTAC GFR300C15JC2TK 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 GFR300C15JC2TK is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This size 300 unit has a 1/2 in NPT port, the standard 40 um filter element, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough. The outlet pressure is set with the adjusting knob over the standard range of 0.15-0.9 MPa (20-130 psi), read on the fitted round psi gauge, and a reverse (check) valve is built in. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The bowl on this size is polycarbonate (PC); mounting bracket is not included (code J).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, PT as the standard thread and G (BSPP) or NPT as order options, with manual, automatic or differential-pressure drains, 40 um or 5 um (W) elements, and embedded square or external round gauges in MPa, psi or bar scales. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Feeding a workshop air press or clamp cylinder bench: the GFR300C15JC2TK strips water and pipe-scale from the shop air at the 1/2 in drop and lets the operator set a stable, repeatable working pressure for consistent forming and clamping results.
On a cartoning or case-packing line running air cylinders, grippers and diverters around the clock, this unit cleans the supply and holds the set pressure so pick-and-place and sealing motions stay consistent through a shift, while the differential-pressure drain keeps condensate off the valves.
Built into the air-preparation panel of a CNC machine tool or automated workholding fixture, where a filtered, regulated 1/2 in supply feeds clamps, tool-change cylinders and air blast, and the check valve helps hold the downstream circuit if the main supply dips.
Size 300 with a 1/2 in port sits in the middle of the GFR range; step up to 400 or 600, or down to 200, as your line's flow demand dictates - we will check the published flow curves against your application before you order. This unit carries the standard 40 um element (choose code W for 5 um where finer filtration is needed) and the differential-pressure drain, which needs no daily attention; a manual (M) or automatic (A) drain can be ordered instead. The fitted round gauge reads in psi; embedded square gauges and MPa or bar scales are alternatives. This code specifies the NPT thread - PT is the catalogue standard and G (BSPP) is also available - and no mounting bracket; order the bracket option if you want panel or wall fixing. Regulation range on this configuration is 0.15-0.9 MPa (20-130 psi).
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 performance curves, not as a single rated number, so there is no one l/min or SCFM figure we can quote honestly. Tell us your line pressure, set pressure and the air demand of your equipment, and we will confirm the flow from the datasheet curves and check the sizing against your application before you order.
K means a reverse (check) valve is fitted, so air will not flow back through the unit toward the supply side. The drain on this unit is the differential-pressure type (no drain letter in the code): it discharges collected condensate automatically when the pressure drop across the 40 um element is sufficient, so there is no drain valve to operate daily; manual (M) and automatic (A) drain versions can be ordered instead.
