The AirTAC GFR300C15F2G AirTAC Filter Regulator G1/2 (1/2 in) 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 GFR300C15F2G is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the size 300 unit with a G1/2 (1/2 in) port, 40 um standard filtration, a differential-pressure drain and a standard regulator with an adjustment range of 0.15-0.9 MPa (20-130 psi). It includes the embedded square gauge scaled in psi and a mounting bracket, 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 family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and order options include automatic or manual drains, a 5 um filter element (code W), gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Feeding clean, regulated air to the clamps, fixtures and tool-changer cylinders of a machining center, where the 40 um element keeps water and swarf-borne particulate out of the actuator circuit and the regulator holds a set pressure at the cell.
Conditioning the air that drives the pushers, sealers and gripper cylinders on a carton-packing conveyor, with the G1/2 port matching the main drop leg and the square psi gauge letting line staff read the set pressure at a glance.
Supplying filtered, pressure-regulated air to impact drivers, nutrunners and air ratchets at a multi-station assembly bench, where the differential-pressure drain carries condensed water out of the bowl and the bracket fixes the unit to the bench frame.
Start with the size and port: the GFR300 with its G1/2 port sits mid-range in the 200/300/400/600 series, and stepping up a size trades a larger port for more flow capacity. Drain type is a real choice on this family - the differential-pressure drain fitted here is the default, with automatic (code A) and manual (code M) available as order options. Filtration is 40 um standard; specify the W option for 5 um where finer protection is needed. The embedded square gauge is standard (psi scale on this unit) with MPa and bar scales and an external round gauge as options, and the thread is G on this model while PT is the standard thread and G/NPT are catalogue options to order. A mounting bracket is included. Flow for the GFR300 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.
AirTAC publishes flow for the GFR300 as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure and air-consumption details and we will confirm the flow and sizing from the datasheet on request.
The differential-pressure drain fitted on this unit is the default for the GFR family and works off the pressure differential across the element. Automatic (code A) and manual (code M) drains are catalogue options on the same size 300 body - specify the code you want when ordering.
