The AirTAC GFR30015AJF2G AirTAC Filter Regulator G1/2 Auto Drain 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 automatic 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 GFR30015AJF2G is a GFR300-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a G1/2 (BSPP) port, a 40 um standard filter element, an automatic drain that ejects collected condensate without manual attention, and a fitted embedded square gauge reading in psi. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and no reverse/check valve is fitted. The 'J' code means no mounting bracket is supplied, so plan to support the unit from your own pipework or panel.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with a choice of ports, drain types (differential-pressure, automatic or manual), a 5 um element option (code W), gauge scale options and G or NPT thread variants. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing figures for your application 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.

Mounted at the drop feeding a pneumatic press or clamping station, this unit filters water and swarf from the shop air line and holds a steady regulated pressure so the press cylinder cycles consistently shift after shift. The automatic drain keeps condensate off the valve stack without an operator having to bleed the bowl.
On a packaging or cartoning line with many small cylinders and air-driven sealers, a G1/2 filter regulator at the line drop cleans the air and sets one stable pressure for all the downstream actuators, while the psi gauge gives operators a visible setpoint to check at a glance.
Installed at the air drop serving an assembly cell with air tools and pick-and-place cylinders, this unit takes the plant supply, strips out water and particulate at 40 um, and regulates it to the pressure the cell was set up for. The automatic drain suits a drop that is not visited every shift.
Size 300 with a G1/2 port sits mid-range in the GFR line: step up to 400/600 or down to 200 depending on the pipe size and flow demand of your circuit. The automatic drain on this unit suits unattended or hard-to-reach installations; choose manual or differential-pressure drain codes where controlled or pressure-differential draining is preferred. The 40 um element is the standard grade for general air preparation - specify the 5 um (W) option only if finer filtration is required. The fitted square gauge reads in psi; MPa or bar scales and an external round gauge are alternatives. Thread is G (BSPP) here, with PT (standard) and NPT available as order options, and the 'J' code omits the bracket, so factor in your own mounting. Because flow is published as curves and not a single rating, 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 number, so we do not quote a l/min, m3/h or SCFM figure. Tell us your application and line pressure and we will confirm the relevant flow and sizing data from the datasheet on request before you order.
The 'A' in the code GFR30015AJF2G specifies an automatic drain, which ejects collected condensate from the bowl without manual attention - useful for unattended or hard-to-reach positions. The same GFR300 size is also available with a manual drain or the differential-pressure drain (the blank default), and with a 5 um element (code W), so ask us for the alternative code if your installation suits a different drain.
