The AirTAC GFR300C10JF3T AirTAC Filter Regulator 3/8 in NPT 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 GFR300C10JF3T is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in a single body. This unit is the 300 size with a 3/8 in NPT port, a differential-pressure drain, the standard 40 um filter element, and a standard regulator adjustable from 0.15-0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi). It is rated for -5 to 70 C (non-freezing), carries an embedded square gauge reading in bar, and is supplied without a mounting bracket or reverse/check valve. The bowl at this size is polycarbonate (PC).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and can be ordered with automatic or manual drains, a finer 5 um element (code W), G (BSPP) or NPT threads in place of the PT standard, alternative gauge scales, an external round gauge, and a mounting bracket. 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 filtration and regulation for clamps, chucks and part ejectors on a machining centre, keeping condensate and swarf-laden air out of the actuator circuit.
Filtered, regulated air for stopper cylinders, pushers and diverters along a bottling or carton-packing conveyor line, with the bowl catching water before it reaches the valves.
Stable downstream pressure for air cylinders and grippers on a manual assembly line, protecting sensitive control valves from dirt and moisture in the shop air.
Size and port set the air capacity: this 300-size unit takes a 3/8 in NPT port; step up to 400 or 600 for larger air demand, or down to 200 for compact point-of-use drops. Drain choice matters: differential-pressure (this unit) clears the bowl as system pressure falls, automatic (code A) drains on its own, and manual (code M) needs a periodic press. Filter grade is 40 um standard or 5 um with code W for finer protection of downstream equipment. Gauge scale is selectable (MPa, psi or bar; this unit reads bar) and the thread can be ordered in PT (the standard), G (BSPP) or NPT. A mounting bracket is optional. Because flow is published as curves rather than a single rated figure, send us your flow and pressure requirements 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
Flow for the GFR300 series is published as curves rather than a single rated figure, so we do not quote a number here. Send us your required flow and inlet and outlet pressures, and we will confirm the sizing from the AirTAC datasheet before you order.
This configuration uses a differential-pressure drain, which discharges collected condensate when system pressure falls. If you prefer automatic draining (code A) or a manual drain (code M), those variants can be ordered in the same 300 size and port.
