The AirTAC GFR30015AJF1WTK AirTAC Filter Regulator NPT1/2 5um is a genuine G-series filter regulator: water separation, 5 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 GFR30015AJF1WTK is an AirTAC GFR300 filter regulator: a single body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is built with a 1/2 in NPT port, a 5 um filter element (the finer of the two catalogue grades), an automatic drain that expels collected condensate without manual attention, an embedded square pressure gauge scaled in MPa, and a reverse/check valve fitted. 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) and an operating temperature of -5 to 70 C (non-freezing). The polycarbonate bowl suits the 300 size, and this unit comes without a mounting bracket.
This is a genuine AirTAC part. The GFR filter-regulator line spans sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, PT as standard thread and G or NPT as order options, a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, gauge and scale choices, and an optional low-pressure regulator type. Flow is published in the catalogue as curves rather than a single rated figure, so ask us to confirm flow and other datasheet values 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.

Feeding clean, regulated air to the tool-change and clamping circuits of a machining centre, where the 5 um element protects precision valves from particulate and the automatic drain handles condensate without operator rounds.
Regulating air to pneumatic diverters, sealers and pushers on a packaging conveyor, with the check valve holding downstream pressure during supply dips and the MPa gauge giving operators a clear setpoint readout.
Installing at the take-off point where a factory air main serves a work cell, combining water and particle removal with local pressure adjustment so the cell runs at its own setpoint independent of the main header.
Sizing starts with the port and size step: the 300 body with a 1/2 in NPT port sits in the middle of the GFR range (200/300/400/600), so step up to 400 or 600 if your line's flow demand is likely to exceed what a 300-size body carries, or down to 200 for compact circuits. This unit already carries the 5 um element; the standard grade is 40 um, so keep 5 um where downstream valves, cylinders or instruments need finer protection. Drain choice matters: automatic drain (as fitted here) suits unattended or hard-to-reach installations, while manual and differential-pressure drains suit attended setups. The embedded square gauge is scaled in MPa; psi and bar scales and an external round gauge are available as options. Thread is NPT here; PT is the catalogue standard and G (BSPP) is also orderable. A mounting bracket can be added if this no-bracket unit needs panel fixing.
One honest note before you order: catalogue flow data is published as curves, not a single rated number, so send us your application's flow and pressure requirements and we will confirm sizing against the datasheet before you commit.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves rather than a single rated figure, so we do not quote one number. Send us your application's flow and pressure conditions and we will confirm the sizing from the datasheet on request before you order.
The A in the code specifies an automatic drain, which expels collected condensate from the bowl without manual attention - useful for unattended or hard-to-access installations. The GFR family is also available with a manual drain or the differential-pressure drain as the default type, so you can order the drain style that suits your maintenance routine.
