The AirTAC GFR300C10F2K AirTAC Filter Regulator PT3/8 | 40 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 GFR300C10F2K is an AirTAC GFR300 filter regulator: a single body that removes water and particulate from compressed air and holds downstream pressure steady. This configuration is a size 300 unit with a PT3/8 port, the standard 40 um filter element, a polycarbonate bowl with differential-pressure draining, and a standard regulator adjustable from 0.15 to 0.9 MPa (20-130 psi). The embedded square gauge is supplied scaled in psi, a reverse (check) valve is fitted, and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and can be ordered with manual or automatic drains, a 5 um element (code W), G or NPT threads, alternative gauge scales, or without the check valve. Flow figures are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details 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.

Filtered, regulated air to pneumatic clamps and vises on a machining centre, keeping water and chips-carried condensate out of the clamp cylinders while holding the set clamp pressure.
Supplying the air cylinders that push cartons between conveyor lanes on a packaging line, with the regulator set to the pressure the diverter cylinders were designed for and the gauge readable at the machine.
Point-of-use conditioning on a laboratory pneumatic test bench, where the 40 um element and a stable, adjustable set pressure protect instruments and actuators downstream.
Choose the size and port against the air your circuit actually uses: 200, 300, 400 and 600 step up in port and flow capacity, and this unit sits at size 300 with a PT3/8 port. Drain type is a real choice - differential-pressure draining (this unit), automatic (A) or manual (M) - and the filter element is 40 um standard or 5 um with code W. Gauge scale (MPa, psi or bar), thread (PT standard, G or NPT to order), the check valve and the bracket are all specified in the code. Because AirTAC publishes flow as curves rather than a single rated figure, send us your flow and pressure requirements and we will confirm the right size from 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.
AirTAC publishes flow for the GFR series as curves rather than a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm sizing from the datasheet on request.
The F2 code on this model specifies the embedded square gauge with a psi scale. MPa and bar scales are catalogue options, and an external round gauge can be ordered instead - just tell us your preference when ordering.
