The AirTAC GFR300C15LC2WT AirTAC Filter Regulator NPT 1/2 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 AirTAC GFR300C15LC2WT is a filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This 300-size unit is threaded NPT 1/2 in, carries a 5 um filter element (the finer of the two published grades), and uses the differential-pressure drain. The regulator is the low-pressure type, and the unit is fitted with a round gauge reading in psi, a metal bowl, and a mounting bracket.
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 for drain type, 40 um or 5 um filtration, gauge style and scale, and PT, G or NPT thread. Rated inlet pressure is 1.0 MPa (145 psi) and working temperature is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm sizing and any datasheet figure 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 swing clamps and risers on a CNC fixture, where the 5 um element helps keep directional and check valves downstream clean.
Conditioning supply air for spray guns and atomising nozzles in a finishing booth, where the 5 um grade and a round psi-referenced gauge suit low-pressure application work.
Regulating filtered air to cylinders and diverters along a packaging conveyor, with the differential-pressure drain fitted as the default condensate arrangement and the included bracket easing mounting.
Choose GFR when you need filtration and regulation in one body. The real, decodable choices on this family: size and port (200/300/400/600, 1/8 to 1 in) stepped against the flow your line needs; drain type - differential-pressure (the default, as fitted here), automatic (A) or manual (M); filter grade - 40 um standard or 5 um (W), which is what this unit carries; gauge - embedded square as standard or external round, scaled in MPa, psi or bar (this unit has the round psi gauge); thread - PT as the standard, with G and NPT as order options (this unit is NPT); and the bracket, which is included here. The L code marks the low-pressure regulator type.
Flow for this family is published as curves, not a single rated figure, so we cannot quote one number here. Send us your application details and we will confirm sizing, and the exact setpoint range of the low-pressure type, from the datasheet before you order.
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, not a single rated figure, so we do not quote a number here. Tell us your port size, upstream pressure and air demand, and we will confirm the flow curve and correct sizing from the datasheet on request.
It marks the low-pressure regulator type. The exact setpoint range for the low-pressure version is not published in the material we hold, so we confirm it from the datasheet on request rather than quoting a figure.
