The AirTAC GFR Filter Regulator GFR300C10AF1 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 GFR300C10AF1 is a G-series filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure at a set point. This 300-size unit has a PT3/8 port, an automatic drain that discharges condensate without operator attention, a standard 40 um element, and the F-coded square pressure gauge on an MPa scale. No reverse valve is fitted. As an automatic-drain regulator its adjustment range is 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi).
This is a genuine AirTAC part. G-series filter regulators come in 200, 300, 400 and 600 sizes with ports from 1/8" to 1", drain choices of differential-pressure, automatic or manual, 40 um or 5 um elements, and PT, G or NPT threads; working temperature is -5 to 70 C, non-freezing. The 300-size polycarbonate bowl suits this mid-range port. Flow is published as curves rather than a single rating, so we confirm flow and full 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.

Filtering and regulating the 3/8 air drops that feed torque tools and pneumatic screwdrivers along an assembly plant line, with the automatic drain handling condensate at each drop.
Conditioning shop air for impact wrenches and tyre-cage circuits in a commercial truck service bay, where the square MPa gauge gives a clear set-point readout at the wall station.
Supplying regulated air to the setup and adjustment circuits of a carton packaging machine, where technicians reset pressure at changeover using the built-in square gauge.
Pick this 300 size when the branch line needs a 3/8 port and the flow demand has moved past the GFR200 body. The F1 code specifies the square gauge on an MPa scale; the embedded square gauge is the base option and the round external gauge is the C alternative. The automatic drain here keeps condensate off the maintenance route - choose manual or differential-pressure drains where that fits the cell better. The 40 um element is the standard grade; add W for the 5 um option only when downstream equipment needs it. Thread is PT as standard, with G (BSPP) and NPT available as catalogue options, and a bracket is included unless J is specified. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application 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 is published for this series as curves, not as a single rated figure, so there is no one number to state. Share your inlet pressure, set pressure and demand, and we will confirm the flow and the full datasheet on request before you order.
F selects the square pressure gauge and 1 sets its scale to MPa. The square gauge is the embedded type; the C code instead orders the external round gauge on the same MPa scale. The rest of the code reads: 300 size, 10 port (PT3/8), A automatic drain, standard 40 um element, no check valve.
