The AirTAC GFR300C15C2K AirTAC Filter Regulator PT1/2, 40 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 GFR300C15C2K is an AirTAC GFR300 filter regulator: a single body that removes water and particulate from compressed air and holds downstream pressure steady. This configuration is built around a 1/2 in PT port, a 40 um standard filtration element and a differential-pressure drain that bleeds collected condensate away as air flows through the polycarbonate bowl. The standard regulator spans 0.15-0.9 MPa (20-130 psi), a round gauge graduated in psi shows the set pressure, and a reverse/check valve is fitted to hold downstream pressure if the supply dips. A mounting bracket is included.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, PT as standard and G (BSPP) or NPT to order, plus a 5 um (W) filtration option, automatic or manual drains and alternative gauge scales where the family supports them. Max 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 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 tool-changer and clamping cylinders on a CNC machining centre, where a 1/2 in supply drop serves several actuators from one conditioning point.
Regulating air to diverter gates and pusher cylinders on a bottling or carton packaging conveyor, keeping actuator movement consistent as plant supply pressure wanders through the shift.
Supplying clean, regulated air to quarter-turn pneumatic valve actuators on a process skid, with the fitted check valve holding the set pressure during brief upstream supply dips.
Choose the size by port and demand: this GFR300 carries a 1/2 in PT port within a range that steps from 1/8 in (size 200) to 1 in (size 600), so move up a size when your air demand outgrows the port. Drain options are differential-pressure (fitted here, bleeding condensate as air flows), automatic (code A) or manual (code M); filtration is 40 um standard or 5 um with code W. Gauge scales are available in MPa, psi or bar, and thread is PT as standard with G (BSPP) and NPT as order options; a bracket is included unless code J is specified. Because flow is published as curves rather than a single rated figure, send us your demand and we will confirm sizing against 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 flow for the GFR series as curves rather than a single rated figure, so there is no one number we can honestly quote. Tell us your working pressure and air demand and we will confirm the flow curve and datasheet figures for this model on request.
This unit's differential-pressure drain bleeds condensate away whenever air flows through the bowl, with nothing to set or power. Choose code A for an automatic drain if your flow is intermittent, or code M for a manual drain you empty yourself on lightly loaded lines.
