The AirTAC GFR300C10JF2WG AirTAC Filter Regulator G3/8, 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 AirTAC GFR300C10JF2WG is a filter regulator: water and particulate removal plus downstream pressure regulation combined in one 300-size body. This configuration carries 3/8 inch G (BSPP) ports, a 5 um filter element for finer filtration than the standard 40 um grade, a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough, and an embedded square gauge reading in psi. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, and the unit is supplied without a mounting bracket.
This is a genuine AirTAC part from the GFR300 series. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and is orderable with manual or automatic drains, a 40 um or 5 um element, square or round gauges in MPa, psi or bar scales, PT, G or NPT threads, and with or without a bracket. Flow is published as curves rather than a single rating, so ask us to confirm the 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.

Fitted on the drop feeding a CNC machining centre, the 5 um element keeps fine contamination out of the machine's solenoid valves and the regulator holds a steady setting for clamping and tool-change cylinders.
On a packaging or bottling conveyor line, this unit filters and regulates the air feeding the divert, push and seal cylinders, with the psi gauge giving operators a visible setpoint at the machine.
Ahead of a pneumatic valve positioner on a process line, the 5 um grade protects the positioner pilot from particulates while the regulator holds the signal pressure the positioner expects.
Start with the port step: this unit is 3/8 inch G thread on the 300-size body, so step up to a 400 or 600 size if your line runs larger ports or higher air demand, or down to 200 for compact drops. The 5 um element in this code suits points of use that see fine contamination, while the standard 40 um grade is the usual choice for general line prep. The differential-pressure drain fitted here needs no operator attention; choose a manual drain where bowls are mounted in awkward spots and someone can bleed them on a schedule, or an automatic drain for unattended duty. The square gauge is fitted and reads psi; MPa or bar scales and an external round gauge are orderable. PT is the standard thread and G or NPT are catalogue options to order, and a bracket can be added if the unit will not hang on the wall plate. Because flow is published as curves rather than a single rating, send us your flow and pressure requirements 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 GFR300 series as curves rather than a single rated figure, so we do not quote one number. Tell us your working pressure and air demand and we will confirm the flow from the datasheet for this exact configuration before you order.
The W code in the model number selects the 5 um element, which captures finer particles than the standard 40 um grade. It is the usual choice for points of use with sensitive valves, actuators or instruments; the 40 um grade remains available for general line preparation.
