The AirTAC GFR30015JC3T 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 PT1/2" 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 GFR30015JC3T is a 300-size filter regulator that removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration carries 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, so no manual draining routine is needed. Pressure is set with the fitted round gauge reading in bar, the regulator is the standard (non low-pressure) type, no reverse/check valve is fitted, and the unit is supplied without a mounting bracket.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, optional 5 um filtration (code W), automatic or manual drains, gauge and scale choices, and G/NPT thread options. 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.

Filtered, regulated air for the tool-changer and clamping circuits on a CNC machining center, with the 1/2 in NPT port feeding the cell's main air drop and the bar gauge giving operators a visible setpoint.
Clean, pressure-set air for the pick-and-place cylinders and diverters on a carton packaging line, where the differential-pressure drain keeps condensate off the valves without a daily bowl-draining task.
A filter-regulator point at the take-off from a factory ring main, conditioning supply for downstream air tools and actuators while the 40 um element catches pipe scale and rust from the distribution piping.
Choose the GFR300 size step by matching the 1/2 in port against the flow your line needs - larger sizes carry larger ports and more flow, and we will confirm the curve against your demand before you order. The 40 um element suits general plant air; specify the W code if you need 5 um. The differential-pressure drain on this model is the fit-and-forget choice; automatic (A) or manual (M) drains are available in the family if your maintenance routine prefers them. The round gauge here reads in bar; MPa and psi scales and the embedded square gauge are the other catalogue choices. Thread: PT is the AirTAC standard and this code specifies NPT; G (BSPP) is the other order option. A mounting bracket (J = none) can be added if you want the unit secured to a panel or wall.
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 number, so there is no one figure we can honestly quote. Send us your application's flow demand and we will confirm the sizing against the datasheet curves on request before you order.
The trailing T decodes to a 1/2 in NPT port. PT is the AirTAC standard thread and G (BSPP) is the other catalogue option - both are order choices, not delivery promises. If your pipework is BSPP or PT, select the corresponding code in the GFR300 series instead.
