The AirTAC GFR300C15F2K 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 AirTAC GFR300C15F2K is a GFR300-series filter regulator: one body that removes water and particulate from compressed air and holds the downstream pressure at your setpoint. This configuration has 1/2 in PT ports, 40 um standard filtration, a differential-pressure drain on the polycarbonate bowl, an embedded square gauge reading in psi, a fitted reverse (check) valve, and the mounting bracket included. Maximum inlet pressure is 1.0 MPa (145 psi), the standard-type regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and the unit is rated -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR line, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in and options including 5 um (W) filtration, automatic or manual drains, alternate gauge scales, G or NPT threads, and low-pressure regulators. Flow for the GFR300 is published as a curve 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.

Point-of-use conditioning ahead of a CNC cell's pneumatic clamps and chip-blast circuit: the 40 um element catches pipe scale and condensate while the regulator holds a steady setpoint to the tools.
Feeding carton sealers and case packers on a packaging conveyor line, where the check valve protects the setpoint against backflow and the drain keeps condensate out of the cylinders.
Regulated, filtered air at an assembly station running air cylinders and impact drivers, with the psi gauge letting operators verify line pressure at a glance during shift checks.
Size the GFR300 to your line: within the GFR family, sizes 200, 300, 400 and 600 step up in port and flow capacity, and this unit carries 1/2 in PT ports (G or NPT threads are order options). Choose the drain to match your maintenance routine: differential-pressure (as fitted here) bleeds condensate as the pressure differential rises, automatic (A) drains hands-free, and manual (M) is emptied on a schedule. Filtration is 40 um standard; specify W for 5 um where finer protection is needed. The square gauge here reads psi, with MPa and bar scales and an external round gauge available. A bracket is included. Because flow is published as curves rather than a single rating, send us your flow and pressure requirements and we will confirm the correct size 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.
Flow for the GFR300 is published as a curve, not a single rated number, so we do not quote a figure here. Send us your required flow and working pressure and we will confirm the datasheet curve and correct sizing on request.
The differential-pressure drain is the default arrangement: it bleeds accumulated condensate from the bowl when the pressure differential across the filter rises. If you prefer hands-free or scheduled draining, automatic (A) and manual (M) drain versions are orderable in the same series.
