The AirTAC GFR30015F1T AirTAC Filter Regulator NPT 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 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 GFR30015F1T is a 300-size filter regulator that removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration is 1/2 in NPT thread, carries the standard 40 um filter element, and drains condensate by differential pressure, so the bowl bleeds automatically as flow passes through it. The fitted embedded square gauge reads in MPa, and the standard regulator covers a setting range of 0.15-0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi). Operating temperature is -5 to 70 C (non-freezing), and the PC (polycarbonate) bowl suits the 300 size.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port options from 1/8 to 1 in, PT as the standard thread and G or NPT as order options, plus drain choices (differential-pressure, automatic, manual), a 5 um filter grade (code W), gauge scale choices and bracket variations. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

Feeding clean, regulated air to a carton-sealing or wrapping line's cylinders, where the 1/2 in NPT port and 40 um element protect valves from water and debris.
Supplying a set pressure to conveyor stopper and gate actuators on a production line, with the square MPa gauge giving the operator a direct setting reference.
Serving as the single filter-regulator point at the inlet of a machine's pneumatic manifold, combining water/particulate removal and pressure setting in one body.
Step up or down through the GFR sizes (200/300/400/600) to match the port and the flow your line needs - this 300 size takes a 1/2 in NPT connection. Choose the drain to suit access: differential-pressure (this model) bleeds with flow, automatic drains on its own, and manual suits supervised points. Pick 40 um for general air or 5 um (code W) where finer protection matters, and choose the gauge scale (MPa, psi or bar) when ordering. PT is the standard thread; G and NPT are order options, as is the bracket.
Flow for this family is published as curves, not a single rated figure, so send us your application details and we will confirm the datasheet and correct sizing 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 GFR series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and the flow your application needs, and we will confirm the datasheet curve and correct sizing on request before you order.
This unit's blank drain code means differential-pressure drainage: condensate in the PC bowl bleeds off automatically as air flows through, with no operator action. If the unit sits at a low or intermittent-flow point where that method is not reliable, order the automatic-drain (code A) or manual-drain (code M) variant of the same GFR300 size instead.
