The AirTAC GFR30015F2T AirTAC Filter Regulator NPT1/2 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.
The GFR30015F2T is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has 1/2 in NPT ports, the standard 40 um filter element, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and an embedded square gauge reading in psi so the set pressure is visible at the unit. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GFR300 size is one step in a range spanning sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, manual or automatic drain variants, a 5 um element (code W) and an external round gauge available. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures for your application before ordering.

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.

Feeds filtered, regulated air to the pneumatic clamps and workholding fixtures on a machining centre, with the psi gauge letting the setter verify clamp pressure at the unit.
Supplies clean, pressure-controlled air to the cylinders and grippers on a packaging conveyor, where the differential-pressure drain handles condensate during continuous running.
Sits at the drop of a general assembly line to condition and regulate the air feeding impact drivers and air ratchets, protecting the tools from water and scale in the supply.
Start with the port and size step: the GFR300 with 1/2 in NPT ports suits lines where the required flow sits in the middle of the range; step up to size 400 or 600 if your demand is higher, or down to 200 if it is modest. Choose the drain to match the installation: this unit's differential-pressure drain suits steady-flow lines, while the manual variant suits intermittent use and the automatic variant suits unattended duty. The 40 um element is the standard choice for general plant air; specify the 5 um W-code element where finer protection is needed. The fitted square gauge reads in psi; MPa and bar scales and an external round gauge are options. NPT is ordered as the T-code thread, with PT standard and G available; a mounting bracket is included.
Because flow is published as curves rather than a single rated figure, send us your application details and we will confirm sizing against 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 GFR300 series as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure and air demand and we will confirm the sizing from the datasheet on request.
The F2 code in GFR30015F2T specifies the embedded square gauge with a psi scale. MPa and bar scales are available, and an external round gauge can be ordered instead if you prefer a panel-facing readout.
