The AirTAC GFR300C15LJC1TK 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 GFR300C15LJC1TK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This unit is built on the GFR300 size with a 1/2 in NPT thread, the standard 40 um filter element and a differential-pressure drain. Regulation is the low-pressure type, a round gauge scaled in MPa is fitted, and a reverse (check) valve is installed; the unit is supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options including automatic or manual drains, a 5 um (W) filter element, square or round gauges scaled in MPa, psi or bar, G (BSPP) or NPT threads and a mounting bracket. Flow for these units is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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.

Filtered, low-pressure-regulated air to clamping cylinders and swing clamps on a CNC fixture, where the workpiece needs a gentler, controlled clamp pressure than the main shop air line provides.
Air preparation for low-pressure actuation on form-fill-seal and cartoning machines, where sealing bars and guide cylinders run below standard line pressure and clean, dry air protects the mechanism.
Conditioning the air feeding a spray booth or coating line circuit, removing water and particulate that would otherwise mark the finish while holding a reduced, stable pressure setting.
Choose the size by the port and flow step: 200, 300, 400 and 600 map to progressively larger ports and flow capacity - this unit is a 300 with a 1/2 in NPT thread. Drain options are differential-pressure (this unit), automatic (A) or manual (M). The 40 um element is standard; specify W for 5 um filtration. Gauges are embedded square as standard with an optional external round gauge in MPa, psi or bar scales - this unit carries a round MPa gauge. Thread is PT as standard with G (BSPP) and NPT as order options; this unit is ordered in NPT. The J suffix deletes the mounting bracket. Because flow is published as curves rather than one rated figure, 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 GFR flow as curves rather than a single rated figure, so we do not quote one number. Send us your application details and we will confirm the flow and datasheet figures for the GFR300C15LJC1TK on request.
This GFR300 is the low-pressure regulator version. Its exact regulation range is not published in the catalogue data we hold, so we confirm it on request. Maximum inlet pressure is 1.0 MPa (145 psi), and the round gauge fitted is scaled in MPa.
