The AirTAC GFR30015C2G AirTAC Filter Regulator G1/2 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 PT1/2" 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.
GFR30015C2G is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and holds a steady downstream pressure, all in one body. This configuration carries a G1/2 port, a 40 um standard filter element, a differential-pressure drain and a round pressure gauge reading in psi. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, and a mounting bracket is included. The polycarbonate bowl suits non-freezing compressed air from -5 to 70 C, with a maximum inlet pressure of 1.0 MPa (145 psi).
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 options include automatic or manual drains, a 5 um element (code W), square or round gauges with MPa, psi or bar scales, and G or NPT threads. We confirm flow figures and datasheet details on request, since flow is published as curves rather than a single rating.

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 air feeding impact wrenches and pneumatic clamps at a vehicle assembly station, keeping tool supply pressure steady through the shift.
Conditioning the supply to conveyor stopper cylinders and diverters on a carton packaging line, so actuators cycle against a consistent pressure setting.
Supplying clean, regulated air to pneumatic fixtures on a laboratory test bench, where a stable setpoint supports repeatable test conditions.
Size 300 with a 1/2 in G thread sits mid-range in the GFR line-up; step up to size 400 or 600, or down to 200, to match the port and flow path of your circuit. Drain choice is differential-pressure here (the standard), with automatic (A) and manual (M) versions available; the 40 um element is standard and a 5 um W-grade element can be ordered. Gauges come as the embedded square type or this external round type, in MPa, psi or bar scales, and threads can be specified as PT (the standard), G or NPT. A bracket is included on this unit.
Because AirTAC publishes flow as curves and not as a single rated figure, ask us to confirm sizing against the datasheet for 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.
AirTAC publishes GFR flow as curves rather than a single rated figure, so no flow number is quoted here. Send us your application details and we will confirm flow and sizing from the datasheet on request.
This unit uses the standard differential-pressure drain, which clears the bowl as pressure drop builds across the element. If your line runs steadily and you want hands-off draining, order the automatic (A) version; if the unit cycles infrequently, the manual (M) drain lets you drain on demand.
