The AirTAC GFR300C10JC1T AirTAC Filter Regulator NPT3/8 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 GFR300C10JC1T is a 300-size filter regulator: it removes water and particulate from compressed air and holds your downstream pressure steady, all in one body. This configuration carries a 3/8 in NPT port, the standard 40 um filter element, a differential-pressure drain that bleeds condensate automatically as flow passes through, and a round pressure gauge scaled in MPa so you can set and verify outlet pressure at a glance. No mounting bracket is fitted and no reverse/check valve is included, so plan your panel layout accordingly.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um (code W) filtration, gauge styles and MPa/psi/bar scales, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range for this drain type is 0.15-0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, 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.

Feed the pneumatic cylinders on a carton-forming and sealing line: the 40 um element keeps sealing-valve debris out while the regulator holds a steady working pressure so jaw timing stays repeatable across the shift.
Supply the air cylinders that push cartons between conveyor lanes in a distribution centre; clean, regulated air keeps the gate actuators from creeping as plant pressure fluctuates during peak hours.
Regulate supply to clamping fixtures on a CNC workholding manifold, where a stable set pressure protects the clamp sequence and the 3/8 in port feeds multiple clamp circuits from one prep point.
Start with the port and size: this unit steps up to 3/8 in NPT on the 300 frame, which suits lines running more air than a 1/4 in point-of-use drop can carry - match it against your downstream cylinder and valve consumption. Drain choice matters: differential-pressure (as fitted here) needs no attention while air flows, automatic drains condensate on a cycle, and manual drains suit intermittent-duty stations where someone walks past anyway. Filtration grade is 40 um standard; specify the W code for 5 um if you feed delicate valves or instrumentation. Gauge style is round external on this unit, scaled in MPa, with psi or bar scales orderable. Thread is NPT here; PT is the catalogue standard and G (BSPP) is also an option. Brackets are optional - this one ships without, so add one if you panel-mount.
One honest note before you order: AirTAC publishes flow for this series as curves, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the sizing against the datasheet curves before you commit.
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 performance curves rather than a single rated figure, so we do not quote a number on the page. Tell us your application - downstream consumption and working pressure - and we will confirm the relevant datasheet figures for this 300-size, 3/8 in unit on request before you order.
This configuration uses the differential-pressure drain, the default for the series: condensate collected in the bowl is discharged automatically whenever the flow differential across the filter is high enough, so it suits lines that run continuously. If your line runs intermittently or you want scheduled manual blowdowns, the same 300-size body is available with an automatic (code A) or manual (code M) drain instead.
