The AirTAC GFR30010JF2WGK AirTAC Filter Regulator 3/8 in G, 5 um is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/8" 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 GFR30010JF2WGK is a 300-size filter regulator that removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration is ordered with a 3/8 in G (BSPP) port, a 5 um filter element (the W grade, one step finer than the 40 um standard), a differential-pressure drain that bleeds collected condensate automatically as pressure differential builds, an embedded square gauge reading in psi, a built-in reverse/check valve that holds downstream pressure when the supply is lost, and no mounting bracket. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing). The polycarbonate bowl lets you see the condensate level at a glance.
This is a genuine AirTAC part from the GFR filter-regulator line, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and options for drain type, filter grade, gauge style and scale, check valve, bracket and thread form (PT is the standard; G and NPT are order options). Flow is published in the catalogue 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.

Feeding a bench-mounted pneumatic press station: the 5 um element keeps fine particles out of the press valve train, the regulator holds a steady set pressure stroke to stroke, and the check valve holds the setting if the plant air dips.
Supplying the gripper and sealing circuits of a cartoning or wrapping machine: one body filters the machine air, sets the working pressure for the seal cylinders, and the psi gauge gives operators a readable setpoint at the machine.
Serving the air cylinders that raise divertors and stoppers along a conveyor line: clean, regulated air keeps the divert valves cycling consistently, and the differential-pressure drain sheds condensate without a daily walk-round.
Size and port step up together: the 300 size with its 3/8 in G port suits lines drawing more air than a 1/4 in unit can serve, while the 400 and 600 sizes carry larger ports for bigger demand - match the size to the flow your circuit needs. Choose the 5 um W element (as fitted here) when downstream valves, cylinders or instruments are sensitive to fine particulate; keep the 40 um standard grade for general plant air. The differential-pressure drain on this unit needs no daily attention; pick automatic drain for unattended duty or manual drain where an operator drains on schedule. The square gauge reads in psi; round gauges and MPa or bar scales are alternatives. Thread is G (BSPP) here, with PT standard and NPT available to order, and a bracket can be added if the unit will not be piped rigidly. Because flow is published as curves and not 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves, not as a single rated number, so we do not quote a l/min or SCFM figure. Send us your line pressure, set pressure and expected air demand, and we will confirm the sizing against the datasheet on request.
The W code in the model orders the 5 um filter element instead of the 40 um standard, for circuits with finer-tolerance valves or instruments. The K code fits a reverse/check valve, which holds downstream pressure if the upstream supply is interrupted. Both are order options; the 40 um grade and no check valve are the defaults if you would rather keep it simple.
