The AirTAC GFR30015AJF2WT AirTAC Filter Regulator NPT1/2 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 GFR30015AJF2WT is an AirTAC GFR300 filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This configuration is built around a 1/2 in NPT port, a 5 um filter element (the finer W grade, versus the 40 um standard), and an automatic drain that bleeds collected condensate from the PC (polycarbonate) bowl without manual attention. The standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi) under a maximum inlet pressure of 1.0 MPa (145 psi), and the fitted embedded square gauge reads in psi so set-points are checked at a glance. A reverse/check valve is not fitted and no mounting bracket is included. Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans 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, plus drain, filter-grade, gauge-scale and bracket choices. Flow is published in the catalogue as curves rather than a single rated figure, so ask us and we will confirm the datasheet 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.

Feeding clean, pressure-controlled air to pneumatic clamps and tool-change cylinders on a machining centre, where the 5 um element helps protect precision valve spools and the psi gauge lets setters verify clamp pressure at the drop.
Conditioning the air feeding gripper and vacuum-generator circuits on a carton or bottle packaging line, with the automatic drain handling condensate on equipment that runs unattended across shifts.
Filtering and regulating the air supplied to spray guns or air-assisted applicators in a finishing booth, where the 5 um grade supports cleaner atomising air and the regulator holds a steady gun supply pressure.
Size 300 with a 1/2 in port sits mid-range in the GFR line: step up to 400 or 600 for larger port sizes and higher flow capacity, or down to 200 for compact circuits - match the step to the air demand of the circuit rather than the fitting alone. The 5 um element (code W) suits applications where finer particulate matters; the 40 um standard element remains the default for general plant air. The automatic drain on this unit suits unattended or hard-to-reach installations; manual and differential-pressure drains are the alternatives. The square gauge here reads psi, with MPa and bar scales available, and an external round gauge is optional. Thread is NPT on this code; PT is the catalogue standard and G is also orderable. No bracket is included on this code, so plan fixing accordingly.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated number, so we do not quote a flow figure here. Send us your application details and we will confirm the datasheet curves against your required flow 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 family as curves in the catalogue, not as a single rated figure, so we do not quote a number here. Tell us your application and required flow and we will confirm the datasheet curve figures for this 1/2 in port size on request before you order.
The A in the code specifies an automatic drain, which expels collected condensate from the PC bowl without operator attention - useful for unattended or hard-to-access installations. The same GFR300 series is also available with a manual drain or the differential-pressure drain as the default, and the filter element can be ordered as the 40 um standard instead of this unit's 5 um W grade.
