The AirTAC GFR300C10F2 AirTAC Filter Regulator, PT3/8, Square Gauge 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 GFR300C10F2 is an AirTAC GFR filter regulator: filtration and pressure regulation combined in one body, so a single size 300 unit removes water and particulate from compressed air and holds a stable downstream pressure. This configuration has a 3/8 in PT port, the standard 40 um filter element, a differential-pressure drain, and a standard regulator with a 0.15-0.9 MPa (20-130 psi) setting range. An embedded square gauge reading in psi is fitted, the mounting bracket is included, and the polycarbonate bowl suits the -5 to 70 C non-freezing operating range at up to 1.0 MPa (145 psi) maximum inlet pressure.
This is a genuine AirTAC part. The GFR line runs from size 200 to 600 with port sizes from 1/8 in to 1 in, and options include the finer 5 um element (code W), automatic or manual drains, G (BSPP) and NPT threads, gauge scales in MPa, psi or bar, and an external round gauge. Flow is published as curves rather than a single rating, so we confirm flow and datasheet figures on request to match 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.

Feeding filtered, regulated air to a pneumatic press or clamping fixture on a production line, where the 40 um element keeps water and swarf out of the valve stack and the regulator holds a steady setting for consistent forming.
Supplying diverter gates and stop cylinders on a packaging conveyor, with the square psi gauge letting operators check line pressure at a glance and the differential-pressure drain clearing collected condensate.
Regulating air to grippers and small actuators on a laboratory automation skid, where the size 300 body and 3/8 in port suit a distributed drop-leg supply with local pressure control at each station.
Size 300 with a 3/8 in PT port sits mid-range in the GFR line (200/300/400/600); step up or down a size when the flow curve for your air consumption demands it - we confirm the curve against your application before you order. This unit is configured with the 40 um standard element (5 um, code W, is the finer option), a differential-pressure drain, a standard regulator covering 0.15-0.9 MPa (20-130 psi), and an embedded square gauge reading in psi; external round gauges and MPa or bar scales are order options. Thread is PT as standard with G (BSPP) and NPT as catalogue options, and the mounting bracket is included. Because flow is published as curves and not a single rating, ask us to confirm sizing against the datasheet for your working pressure before ordering.
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 is published as curves rather than a single rated figure, so we do not quote a number here. Send us your application's air consumption and working pressure and we will confirm sizing against the datasheet curves before you order.
This unit carries the standard 40 um element, which suits general plant air protecting cylinders, valves and air tools from water and particulate. If you are feeding precision components or instrumentation, the W variant with the 5 um element is the better choice. Ask us to confirm the right grade for your application.
