The AirTAC GFR300C10AJF2WT AirTAC Filter Regulator, NPT3/8, 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 GFR300C10AJF2WT is a filter regulator: it removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration is built for 3/8 in NPT ports, carries the fine 5 um element (40 um is the standard grade; code W selects 5 um), drains condensate automatically, and shows the set pressure on the embedded square gauge with a psi scale. Maximum inlet pressure is 1.0 MPa (145 psi), the regulation range is 0.15-0.9 MPa (20-130 psi), and the working temperature is -5 to 70 C, non-freezing. The bowl is polycarbonate (PC); only the 600 size uses an aluminium alloy bowl.
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600, with a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, embedded square or optional external round gauges scaled in MPa, psi or bar, PT (standard), G or NPT threads, bracket or no-bracket mounting, and an optional reverse/check valve. Flow is published as curves rather than a single rating, so ask us to confirm figures from the datasheet 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.

Point-of-use air preparation for a CNC machining cell: the 5 um element helps keep water and particulate out of the solenoid valves on clamps and tool changers, while the regulator holds a steady setting on the machine's air circuit and the psi gauge lets a technician verify it.
Filtering and regulating supply to pneumatic nutrunners and clamping fixtures along an automotive assembly line, where the automatic drain clears collected condensate on circuits that run unattended across shifts.
Supplying filtered, regulated air to carton-forming and sealing heads on a packaging conveyor, with the embedded square psi gauge letting machine setters set and check actuator pressure at the point of use.
Size and port: the GFR300 steps up from GFR200 when the line needs more flow through 3/8 in ports; GFR400 and GFR600 serve larger circuits. Drain: automatic drain (this unit) suits points that run unattended; manual drain needs an operator to visit the bowl; differential-pressure drain is the catalogue default. Filtration: 40 um protects most general circuits, while the 5 um element fitted here gives finer protection for sensitive downstream equipment. Gauge: the embedded square gauge is standard and this unit reads psi; round external gauges and MPa or bar scales are options. Thread: PT is the standard, with G and NPT as order options - this unit is NPT. No mounting bracket is fitted (code J); choose a bracketed variant if you need to panel-mount. Flow is published as curves, not a single rating, so send us your flow and pressure requirements and we will confirm sizing from 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 a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm the sizing from the GFR300 datasheet on request.
The 40 um element is the standard grade and suits general circuits; the W code selects the finer 5 um element for better protection of downstream valves, cylinders and instruments. This unit is supplied with the 5 um element. Both grades share the same body, 3/8 in NPT porting and 0.15-0.9 MPa (20-130 psi) regulation range.
