The AirTAC GFR30015F2G AirTAC Filter Regulator, G1/2 Port, 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 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.
The AirTAC GFR30015F2G is a filter regulator in the GFR300 series: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is fitted with a G1/2 port, a 40 um standard filter element, a differential-pressure drain and an embedded square gauge reading in psi, so one component conditions the air supply and holds the working pressure your equipment is set up for.
This is a genuine AirTAC part from the GFR300 size family, one of four sizes (200/300/400/600) with port options from 1/8 in to 1 in and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi), the regulation range is 0.15-0.9 MPa (20-130 psi) and the operating temperature is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures 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 a solenoid-valve manifold on a packaging machine: the 40 um element keeps debris and condensate out of the valves while the regulator holds a steady set pressure on the G1/2 supply line.
Conditioning the air feed to stopper and pusher cylinders along a conveyor line, with the psi square gauge giving operators a visible set point and the differential-pressure drain handling condensate.
A point-of-use filter regulator on a plant air drop serving air tools and clamping fixtures, combining water and particulate removal with local pressure control in a single G1/2 unit.
Size and port come first: the GFR300 sits in the middle of the range and this unit carries a G1/2 connection, so step up or down a size if your line needs a different port or flow band. Drain choice matters in practice: differential-pressure (fitted here) clears condensate whenever the differential is high enough, while automatic and manual drains are catalogue alternatives. Filter grade is 40 um standard or 5 um with code W, the gauge can be specified in MPa, psi or bar scales, and PT is the standard thread with G and NPT as order options; a mounting bracket is included. 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.
AirTAC publishes flow for this series as curves, not as a single rated figure, so we do not quote one number. Tell us your line pressure and the flow your application needs and we will confirm the sizing from the datasheet on request.
This GFR30015F2G is fitted with the differential-pressure drain, the default option. It discharges collected condensate automatically when the pressure differential across the drain is high enough, with no manual intervention; automatic (code A) and manual (code M) drains are catalogue alternatives if you prefer a different behaviour.
