The AirTAC GFR300C10JF2W 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 GFR300C10JF2W is an AirTAC GFR300 filter regulator: filtration and pressure regulation combined in a single 3/8 in (PT3/8) body for compressed air. This configuration carries the 5 um filtration element (the finer catalogue grade, selected by the W code), a differential-pressure drain, and a factory-fitted embedded square gauge scaled in psi. The polycarbonate bowl is standard at size 300, no mounting bracket is included, and maximum inlet pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part, rated for -5 to 70 C (non-freezing) with a standard-type regulator adjustable from 0.15 to 0.9 MPa (20-130 psi). The GFR family runs from sizes 200 to 600 with ports from 1/8 to 1 in, PT, G (BSPP) or NPT threads, 40 um or 5 um elements, differential-pressure, automatic or manual drains, and square or round gauges in MPa, psi or bar scales. Flow is published as curves rather than a single rating, so we confirm datasheet figures 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.

Point-of-use supply for a CNC machining centre's tool-clamp and chip-door cylinders: the 5 um element protects tight valve clearances from fine particulate while the regulator holds a steady set pressure for repeatable clamping.
Air preparation for stopper and pusher cylinders on a bottling or cartoning conveyor: filtered, regulated air keeps gate cylinders cycling smoothly, and the square psi gauge lets line staff verify the set pressure at a glance.
Supply air for fixture clamps on a robotic welding cell: the filter regulator sits at the cell drop, the 5 um grade guards the clamp valve, and the visible gauge setpoint keeps fixture force consistent across shifts.
Size up from the port step: 300 sits mid-range in the GFR line, so match the 3/8 in port against your piping and the flow the circuit needs - we check the published flow curves with you rather than quoting a single number. The remaining choices are all decodable: drain type (differential-pressure on this unit; automatic or manual are orderable alternatives), filtration grade (5 um here versus the 40 um standard), gauge style and scale (embedded square, psi here; an external round gauge in MPa, psi or bar is optional), thread (PT standard; G and NPT to order) and bracket (not included on this J-coded unit). Before ordering, send us the application conditions and we will confirm sizing against the datasheet.
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 GFR300 flow as curves, not as a single rated number, so we do not quote a figure here. Send us your application's flow and pressure requirements and we will confirm sizing against the datasheet curves before you order.
The W code in GFR300C10JF2W selects the 5 um filtration element in place of the 40 um standard. Choose 5 um where downstream valves, cylinders or instruments need finer protection from particulate; 40 um suits general plant air. Both grades are available across the GFR range.
