The AirTAC GFR300C15JC2WTK AirTAC Filter Regulator NPT1/2, 5 um 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 GFR300C15JC2WTK is an AirTAC GFR300 filter regulator: a single body that removes water and particulate from compressed air and regulates downstream pressure. This size 300 unit is threaded NPT1/2 (1/2 in), carries the fine 5 um filter element (code W), drains condensate by differential pressure, and is fitted with an external round pressure gauge reading in psi plus a reverse/check valve. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing). The polycarbonate bowl suits the size 300 frame, and this configuration ships without a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of 40 um standard or 5 um fine filtration, differential-pressure, automatic or manual drains, gauge scale options in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so we confirm the datasheet and flow figures 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.

Point-of-use conditioning for the air feeding tool clamps and pneumatic actuators on a CNC machining centre: the 5 um element protects spool valves from particulate and water while the regulator holds a steady set pressure for consistent clamping.
Filter-and-regulate the branch line supplying the valve island on a cartoning or wrapping machine, where the round psi gauge lets operators verify set pressure at a glance and the check valve holds the circuit against backflow.
Condition the air drop feeding pick-and-place cylinders and air grippers in a robotic assembly cell, keeping moisture and fine particles out of the actuators while holding the working pressure the cell was commissioned at.
Size 300 with a 1/2 in port sits in the middle of the GFR range; step up to size 400/600 or down to size 200 depending on the air demand of the line. Choose the 5 um element (as fitted here) when downstream valves, cylinders or instruments need finer filtration than the 40 um standard element. Drain options are differential-pressure (fitted, default), automatic, or manual; the differential-pressure drain pairs with the 0.15-0.9 MPa (20-130 psi) adjustment range. Gauge scale can be psi, MPa or bar, and thread can be ordered as PT (standard), G or NPT. A bracket is optional on this family; this code omits it. Flow is published as curves, not a single rating, so 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 GFR300 flow as curves, not as a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Send us your line pressure, set pressure and air demand and we will confirm the flow figures from the datasheet for this exact model before you order.
K means a reverse (check) valve is fitted. It prevents downstream air from flowing back through the unit, which helps hold the regulated pressure in the circuit when the upstream supply is shut off or drops. It is an order option; GFR300 codes without K come without the check valve.
