The AirTAC GFR300C08JF2WT AirTAC Filter Regulator 1/4 in NPT 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 GFR300C08JF2WT is an AirTAC GFR filter regulator: filtration and pressure regulation combined in a single body, with a drain bowl but no lubricator. This configuration is built for a 1/4 in NPT port, carries the 5 um filter element (code W), drains by differential pressure, and has an embedded square gauge reading in psi. The regulator is the standard type, no reverse/check valve is fitted, and no mounting bracket is included.
It is a genuine AirTAC part in the GFR300 size, one of four sizes (200, 300, 400, 600) that step up in port and flow. Max inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. AirTAC publishes flow as curves rather than a single rating, so ask us to confirm flow and 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 filtered, regulated air to the machine's pneumatic valves and actuator circuits, with the 5 um element helping keep fine particulate away from valve spools and tool-change cylinders.
Regulating supply pressure to carton-forming and sealing cylinders on a packaging conveyor, with the differential-pressure drain shedding collected condensate as the pressure difference builds.
Supplying regulated air to palletiser grip and pusher cylinders, where the filter section removes water and particulate ahead of the actuators and the square psi gauge gives operators a local set-point reading.
Size and port are the first choice: the 300 size with a 1/4 in NPT port suits circuits at moderate demand, and stepping up to 400 or 600 gives a larger port when the flow requirement outgrows it. Drain type here is differential-pressure, which sheds collected condensate as the pressure difference across the unit builds; automatic and manual drains are available elsewhere in the family. This unit carries the 5 um element (W) instead of the 40 um standard, so choose it where downstream valves and instruments need finer air. The square gauge is fitted with a psi scale (MPa and bar scales are options), and G (BSPP) or PT thread versions can be ordered. No mounting bracket is included (code J). Flow 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.
AirTAC publishes flow for the GFR300 as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and datasheet figures on request before you order.
It is the 5 um filter element. The GFR family defaults to a 40 um element; the W option gives finer filtration for downstream valves, cylinders and instruments that need cleaner air.
