The AirTAC GFR300C15JC1TK 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 GFR300C15JC1TK is an AirTAC GFR300 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is threaded NPT1/2 (1/2 in), carries the standard 40 um filter element, and drains condensate by differential pressure, so it suits lines that run steadily without manual draining. It is fitted with a round pressure gauge reading in MPa, a reverse (check) valve is built in, and the unit is supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is made in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and offers a choice of drain type, filter grade (40 um standard, 5 um optional), gauge style and scale, thread (PT standard, G and NPT as order options) and bracket. Regulation range for this configuration is 0.15-0.9 MPa (20-130 psi). Rated flow for the series is published as curves rather than a single 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.

Feeding filtered, regulated air to the cylinder manifold that drives capper heads and bottle clamps on a beverage filling line, with the differential-pressure drain handling condensate during long production runs.
Conditioning the air that actuates the workpiece clamps and swing cylinders on a machining-cell fixture, where the 40 um element protects valve spools and the regulator holds a steady clamp pressure.
Supplying clean, regulated air to the diverter gates and pusher cylinders along a parcel-sort conveyor, with the built-in check valve helping hold the set downstream pressure in the circuit.
Size 300 with a 1/2 in NPT port is the mid-range step of the GFR family; move to size 400 or 600 when the line demands more flow, and down to size 200 for compact drops. Because flow is published as curves and not a single rating, ask us to confirm this unit against your air demand before ordering. Drain: this unit uses differential-pressure draining, which suits continuously running lines; automatic (code A) and manual (code M) drains are alternatives in the family. Filter grade: 40 um is standard here; choose the W code for 5 um where finer filtration is needed. Gauge: this unit carries a round gauge with an MPa scale; an embedded square gauge, and psi or bar scales, are catalogue options. Thread: PT is the standard thread, while G (BSPP) and NPT are order options - this unit is built NPT. Bracket: supplied without one (code J); bracketed versions are available.
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 curves, not as a single rated figure, so we do not quote one here. Tell us your line's air demand and we will confirm the sizing from the datasheet curves on request before you order.
K denotes that a reverse (check) valve is fitted in this unit. It is a catalogue option on GFR filter regulators - codes without the K are supplied without the valve. The rest of the code decodes as size 300, 1/2 in port, NPT thread, no bracket, round MPa gauge, and standard regulator type.
