The AirTAC GFR300C10JF2WT 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 GFR300C10JF2WT is a size-300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a 3/8 in NPT port, a 5 um filter element (the finer of the two published grades), a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and an embedded square pressure gauge reading in psi. The standard regulator covers a 0.15-0.9 MPa (20-130 psi) setting range with a maximum inlet pressure of 1.0 MPa (145 psi), and the polycarbonate bowl suits the -5 to 70 C (non-freezing) operating range. No mounting bracket is included in this variant.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and is orderable with manual or automatic drains, a 40 um or 5 um element, alternative gauge scales, G (BSPP) or NPT threads in place of the PT standard, and an optional reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing or any datasheet figure against 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 at the drop feeding a CNC machining centre's pneumatic actuators and tool-change circuit, it cleans the shop air to 5 um and holds a steady regulated pressure so clamps and tool changers repeat consistently.
Mounted on the supply to a cartoning or bagging line's diverter gates and sealing cylinders, it strips water carried in from the compressor and lets the line supervisor dial in the working pressure at the panel gauge.
Installed on the air feed to a test bench or lab instrument station, the 5 um element protects sensitive pneumatic components from particulate while the regulator trims supply pressure to the level the bench needs.
Start with the port step: this unit is the size-300 body with a 3/8 in NPT port; step up to size 400 or 600 if your line needs more flow capacity, or down to 200 for compact drops. Because published flow is given as curves rather than one rated number, ask us to check the curve against your required flow before you order. On filtration, 40 um is the standard element and the 5 um element fitted here suits finer-protection duties; for drain duty, the differential-pressure drain fitted here needs no operator attention, while manual and fully automatic drains are orderable. The embedded square gauge here reads in psi; MPa and bar scales and an external round gauge are alternatives. Thread is NPT on this unit, with G (BSPP) orderable and PT as the catalogue standard. This variant carries no mounting bracket, so plan your mounting plate accordingly.
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 one number here. Tell us your line pressure and required flow and we will confirm from the datasheet curve whether this size-300, 3/8 in unit is correctly sized before you order.
The W code in the model number selects the optional 5 um filter grade instead of the 40 um standard. The finer element gives cleaner air downstream, at the cost of a larger pressure drop across the element; if your application does not need fine filtration, the 40 um version of the same unit is orderable.
