The AirTAC GFR300C15JF1T AirTAC Filter Regulator NPT1/2, 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 GFR300C15JF1T is a filter regulator: water and particulate removal plus downstream pressure regulation combined in one body. This 300-size unit is fitted with 1/2 in NPT ports, a 40 um standard filter element and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the bowl rises. The standard regulator adjusts outlet pressure across 0.15-0.9 MPa (20-130 psi), an embedded square gauge reading in MPa is fitted, and no reverse/check valve is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The bowl on this 300 size is polycarbonate (PC).
This is a genuine AirTAC part. The GFR line spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options include a 5 um (code W) element, automatic or manual drains, alternate gauge scales (psi or bar) and G (BSPP) or NPT threads in place of the PT standard. Rated flow for this series is published as curves rather than a single figure, so ask us and we will confirm the datasheet numbers 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.

Drops feeding air cylinders and air tools at assembly benches get cleaned, moisture-reduced air at a set pressure, with the square gauge letting operators verify the regulated setting at a glance.
Sorting and diverting cylinders on packaging conveyors run consistently when the branch supplying them is filtered to 40 um and held at a stable regulated pressure by one compact unit.
Clamp cylinders on a fabrication cell need steady holding pressure; the GFR300C15JF1T filters the shop air and regulates it to the clamp circuit's set point, with the differential-pressure drain handling condensate between shifts.
Size the unit by the flow your line needs at the outlet pressure you run: step up through sizes 200, 300, 400 and 600 as port size and air demand grow - this 300 size carries 1/2 in NPT ports. Choose the drain to match maintenance access: differential-pressure (as fitted here) needs no daily attention, automatic (code A) suits unattended installations, and manual (code M) suits supervised points. The standard element is 40 um; specify code W for 5 um where finer particulate protection matters. Gauge scale can be MPa (as fitted), psi or bar, and threads can be ordered in G (BSPP) or NPT instead of the PT standard; a mounting bracket is optional (this unit is ordered without one).
Because flow for the GFR series is published as curves and not as a single rated number, send us your air demand and working pressure and we will confirm the correct size 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 we do not quote one number. Tell us your air demand and working pressure and we will confirm the datasheet flow figures for this 300-size, NPT1/2 unit on request before you order.
This unit's differential-pressure drain discharges condensate automatically when the pressure differential across the bowl rises - no daily manual draining. If your installation is unattended or you prefer a fixed service interval, the same size can be ordered with an automatic drain (code A) or a manual drain (code M); the manual-drain version also widens the regulator adjustment range down to 0.05 MPa.
