The AirTAC GFR300C15F2WK 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 GFR300C15F2WK is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This size 300 unit is threaded PT1/2, carries a 5 um filter element (code W), drains condensate by differential pressure, and regulates between 0.15 and 0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi). The embedded square gauge reads in psi, a reverse/check valve is fitted, the polycarbonate bowl suits the included mounting bracket, and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR range, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch and PT, G or NPT thread options. Drain type, filter grade, gauge scale and check-valve choices let you match the unit to the line. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures for your application before ordering.

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 and regulated air feeds the machine's directional valves and air-powered clamps, with the 5 um element guarding against fine particle carryover and the psi gauge giving operators a setpoint readout at the drop.
Stable regulated pressure keeps stopper and pusher cylinders on a bottling conveyor moving at a consistent pace, while the differential-pressure drain clears condensate from the compressor line without daily attention.
A spray booth drop benefits from 5 um filtration ahead of the gun and a fixed regulator setting, with the fitted check valve preventing backflow through the unit.
Choose the size by port and demand: sizes 200, 300, 400 and 600 step up in port and capacity, so match the GFR300's PT1/2 port to your line and let us check the flow curve with you. This configuration pairs a 5 um element with differential-pressure draining - the standard grade is 40 um, and automatic or manual drain can be specified where the installation calls for it. The square psi gauge is standard, an external round gauge in MPa, psi or bar is optional, and G or NPT threads or a no-bracket version are order options. Because flow is published as curves, not a single rating, send us your application details and we will confirm the datasheet figures 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 GFR300 as curves rather than a single rated figure, so there is no one number we can quote. Tell us your working pressure and air demand and we will confirm the sizing from the datasheet on request.
The GFR300 series carries a 40 um element as standard, and 5 um is the W option; this configuration specifies the 5 um grade for finer particulate removal. If your line does not need fine filtration, the 40 um version of the same size can be ordered - ask us to quote it.
