The AirTAC GFR300C15AJF2WG AirTAC Filter Regulator G1/2, 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 GFR300C15AJF2WG is a GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in a single body. This size 300 unit has G1/2 (1/2 inch) ports, a 5 um filter element (code W, against the 40 um standard), an automatic drain that discharges collected condensate without manual attention, and an embedded square gauge reading in psi. The regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the polycarbonate bowl suits ambient temperatures from -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options across the series include manual or differential-pressure drains, the 40 um standard element, square or round gauges with MPa, psi or bar scales, a reverse/check valve, and G or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Feeding film-sealing and carton-eject cylinders on a packaging line: water and scale are stripped from the supply and the cylinder pressure is held steady at the setpoint run after run.
Supplying pneumatic clamps and tool-change actuators on a CNC cell, where a stable regulated pressure keeps workholding consistent from one part to the next.
Running pilot air to solenoid and air-operated process valves in a plant air loop, keeping condensate and grit out of the pilot passages and holding the pilot pressure at its setpoint.
Size and port set the air capacity: this unit is size 300 with G1/2 ports, and larger sizes in the family carry more flow, so step up if your line demand is high. The 5 um element (code W) suits applications needing cleaner air than the 40 um standard, and the automatic drain suits unmanned or hard-to-reach installations, with manual and differential-pressure drains available as alternatives in the family. Gauges come square (fitted here, psi scale) or round external, with MPa, psi or bar scales; a bracket is optional and this configuration is supplied without one; G or NPT threads can be ordered instead of the PT standard.
Because AirTAC publishes flow as curves rather than a single rated number, we do not quote a flow figure here - send us your application details and we will confirm the datasheet and check the sizing against your requirement 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 a number here. Tell us your line pressure, downstream demand and allowable pressure drop, and we will confirm the datasheet curve and check the sizing for your application before you order.
This unit carries drain code A: collected condensate is discharged from the bowl automatically, without manual attention, which suits unmanned or hard-to-access installations. The GFR family is also available with a manual drain or with the differential-pressure drain as the standard default, and the regulator adjustment range depends on which drain type is fitted.
