The AirTAC GFR300C10JC2WG AirTAC Filter Regulator G3/8, 5 um, psi 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 GFR300C10JC2WG is a 300-size filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries 3/8 inch ports with G (BSPP) thread, a 5 um filter element (the finer W grade, versus the 40 um standard), a differential-pressure drain that bleeds condensate automatically whenever the pressure drop across the element is high enough, and a round pressure gauge reading in psi. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), the maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). No mounting bracket is included and no reverse/check valve is fitted in this version.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600, with port options from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures 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.

Feeds clean, regulated air to the tool-change clamps and pneumatic actuators on a CNC machining centre, with the 5 um element protecting tight-tolerance valves from particulate carryover.
Mounted at the drop of a packaging line's air main, it regulates the supply to diverter gates, bag sealers and carton-closing cylinders while the differential-pressure drain sheds condensate picked up in the header.
Positioned ahead of pneumatic valve positioners and actators in a process plant, it holds a steady set pressure to the instruments and filters out pipe-scale and moisture that would otherwise foul the positioner.
Step up or down through the GFR sizes (200/300/400/600) to match the port and flow path your line needs - this 300 size with 3/8 inch G-thread ports suits mid-range circuits. Choose the drain to match maintenance practice: differential-pressure (as coded here) drains on pressure drop, automatic drains on a timed cycle, and manual needs an operator. Choose 40 um for general air prep or the 5 um W grade, as fitted here, where finer particulate protection matters. Gauge options are the embedded square type or an external round gauge, in MPa, psi or bar scales - this unit carries a round psi gauge. Thread is PT as standard with G and NPT as order options, and a bracket can be added where the J (no bracket) version here is not wanted. Because flow is published as curves rather than a single rating, send us your application details 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 characteristic curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure, set pressure and the flow your circuit needs, and we will confirm the sizing against the datasheet curves on request before you order.
W is the filter grade: this unit carries the optional 5 um element instead of the 40 um standard. C is the gauge code for the external round gauge and 2 is its scale, psi. The rest of the code decodes as the 300 size, 3/8 inch G-thread ports, no bracket, standard regulator, differential-pressure drain and no reverse/check valve.
