The AirTAC GFR300C15F2W AirTAC Filter Regulator PT1/2, 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 AirTAC GFR300C15F2W is a GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This size-300 unit is configured with PT1/2 (1/2 in) PT threaded ports, a 5 um filter element (the finer W grade, versus the 40 um standard), a differential-pressure drain that bleeds accumulated condensate automatically whenever the pressure differential across the element is high enough, and an embedded square gauge reading in psi. The standard regulator covers a 0.15-0.9 MPa (20-130 psi) adjustment range with a maximum inlet pressure of 1.0 MPa (145 psi), and the polycarbonate bowl suits non-freezing compressed-air service from -5 to 70 C.
This is a genuine AirTAC part from the GFR300 size family, one of four sizes (200/300/400/600) spanning the port range from 1/8 in to 1 in. Across the series you can order manual or automatic drains, the 40 um or 5 um element, MPa/psi/bar gauge scales, G or NPT threads, and a low-pressure regulator type. We do not quote a single rated flow figure because AirTAC publishes flow as curves; ask us and we will confirm the datasheet figures for your application.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 clean, regulated air to the tool-change clamps and pneumatic actuators on a machining centre, where the 5 um element protects close-tolerance valves from particulate carryover and the psi gauge lets setters verify setpoint at a glance.
Regulating the air feeding conveyor diverters, gate cylinders and bag-seal jaws on a packaging line, with the differential-pressure drain keeping condensate out of the circuit during continuous shifts.
Installed at a drop leg off the main header in a factory bay, giving one work cell its own filtered and regulated air supply at 1/2 in line size, with the included bracket mounting the unit beside the take-off.
Start with the port and size: this unit steps up to PT1/2 on the 300 frame, so check that your line size and expected air demand sit comfortably within the GFR300 flow curve before ordering - we will confirm the curve figures on request. The 5 um element here is the right choice when downstream valves, cylinders or instruments are sensitive to finer particulate than the 40 um standard element removes; if your application tolerates coarser filtration, the 40 um version costs less to run. The differential-pressure drain suits steady-duty lines that see regular condensate loading; choose an automatic drain for unattended duty or a manual drain for light, intermittent moisture. The fitted square gauge reads in psi; MPa and bar scales are available, as are G (BSPP) and NPT threads if PT does not match your piping. A mounting bracket is included, and a reverse/check valve can be specified if you need back-flow protection.
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 rather than a single rated figure, so we do not quote one number. Tell us your line pressure, set pressure and expected air demand, and we will confirm the datasheet curve figures against your application before you order.
The W in the code GFR300C15F2W specifies the optional 5 um filter element instead of the 40 um standard, and F2 specifies the embedded square gauge with a psi scale. If you would rather have the 40 um element, an MPa or bar gauge scale, or an external round gauge, those are catalogue options on the same series - just ask and we will decode the matching part number.
