The AirTAC GFR300C15AJF1WT AirTAC Filter Regulator NPT1/2 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 GFR300C15AJF1WT is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in a single body. This configuration is built around NPT1/2 ports, a 5 um filter element, an automatic drain that clears collected condensate without operator attention, and an embedded square gauge scaled in MPa. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) setting range, no reverse/check valve is fitted, and the unit is supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part in the GFR300 size class. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, filter grades of 40 um (standard) or 5 um (code W), a choice of differential-pressure, automatic or manual drains, and optional external round gauges with MPa, psi or bar scales. Flow and other datasheet figures are published as curves rather than a single rating, so we confirm them 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.

Positioned ahead of a machining centre's pneumatic actuators and tool-change circuits, this unit strips water and particles from the shop air line and holds a steady regulated pressure, with the MPa gauge giving the operator a direct reading at the cell.
On a spray or coating line, the 5 um element reduces particulate reaching the application equipment while the regulator holds a consistent downstream setting, and the automatic drain keeps condensate off the line during continuous production.
Feeding the valve-and-cylinder group on a packaging or cartoning conveyor, this filter regulator keeps the supply air clean and the pressure stable, and the automatic drain handles condensate without a scheduled manual blow-down.
Size and port step up with flow demand: GFR200 through GFR600, with ports from 1/8 in to 1 in. This unit sits at GFR300 with NPT1/2 threads; PT is the standard thread and G or NPT are order options. The 5 um element (code W) suits air feeding sensitive valves and instruments, while the standard grade is 40 um. The automatic drain suits unattended duty; manual and differential-pressure drains are available on other variants. A square MPa gauge is fitted here, and an external round gauge in MPa, psi or bar can be ordered. Flow for this family is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 curves in the AirTAC catalogue rather than as a single rated figure, so we do not quote one number. Tell us your application and we will confirm the flow and other datasheet figures on request before you order.
This configuration carries code A, an automatic drain that ejects collected condensate without operator attention, which suits lines that run unattended. The same GFR family is also available with manual or differential-pressure drains if you prefer a different service approach.
