The AirTAC GFR300C10JF2WK AirTAC Filter Regulator PT3/8, 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 GFR300C10JF2WK is an AirTAC GFR-series filter regulator: water and particulate removal plus downstream pressure regulation combined in a single body. This size-300 unit is threaded PT3/8 and carries the 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain that clears the bowl as system pressure falls, and an embedded square gauge scaled in psi. A 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 working temperature range is -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 the catalogue offers manual or automatic drains, a 40 um standard element, gauge scales in MPa, psi or bar, and G or NPT threads as order options alongside the PT standard. AirTAC publishes flow for these units as curves rather than a single rated figure, so ask us to confirm the flow 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.

Feeds filtered, regulated air to the tool-change and workpiece-clamping circuits of a CNC machining centre, with the 5 um element protecting downstream valves from fine particulate carried in the shop air line.
Supplies clean, regulated air to the pneumatic cylinders that fold and seal cartons on a corrugated packaging line, with the square psi gauge letting operators set and check the working pressure at the machine.
Conditions the air feeding gripper and end-of-arm-tooling actuators in a robotic assembly cell, with the fitted reverse/check valve helping hold the set downstream pressure if the upstream supply is interrupted.
Size and port are the first choice: 200, 300, 400 and 600 step up in port size and flow capacity, and this unit sits at size 300 with a PT3/8 port - match the step to the air demand of the circuit rather than to the pipe alone. Within the family you can choose the drain type (differential-pressure as fitted here, automatic, or manual), the filter element (40 um standard or the 5 um grade fitted here), the gauge scale (MPa, psi or bar) and the thread (PT standard, with G and NPT as order options); a mounting bracket is optional and this configuration omits it.
AirTAC publishes flow for the G-series as curves, not as a single rated number, so no rated flow is quoted here. Send us your application's air demand and we will confirm sizing 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 as a single rated figure, so we do not quote a rated flow number for this unit. Tell us your air demand and operating pressure and we will confirm the flow from the datasheet on request before you order.
The catalogue offers 40 um as the standard element and 5 um as the optional finer grade, coded W; this configuration is built with the 5 um element for circuits that need finer particulate removal ahead of the regulator. If your application does not need the finer grade, the 40 um standard element is the usual choice - ask us to confirm which suits your setup.
