The AirTAC GFR30015JF3T 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 AirTAC GFR300 series combines filtration and pressure regulation in a single body: compressed air passes through a 40 um element that strips out water and particulate, then through a standard-type regulator that sets downstream pressure anywhere in the 0.15-0.9 MPa (20-130 psi) range. This unit is the 300 size with a 1/2 in NPT port, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and a fitted embedded square gauge scaled in bar so operators can read and set line pressure at a glance. The polycarbonate bowl suits the -5 to 70 C (non-freezing) working envelope, and maximum inlet pressure is 1.0 MPa (145 psi).
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, thread choices of PT (standard), G and NPT, manual or automatic drain variants, a 5 um (code W) filter element option, and gauge scale choices of MPa, psi or bar. Flow is published as curves rather than a single rating, so ask us to confirm the 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.

Feeding clean, regulated air to the clutch and cylinder circuit of a small stamping or press machine, where the 40 um element keeps scale and condensate out of the valve stack and the square gauge lets setters verify working pressure in bar.
Conditioning the air feeding grippers, diverters and pusher cylinders on a carton or shrink-wrap packaging line, with the differential-pressure drain handling condensate during continuous production runs without operator attention.
Serving as the point-of-use filter regulator on a 1/2 in plant air drop feeding an assembly bench, so technicians dial in a stable working pressure for air tools and fixtures while the element removes water and pipe scale.
Start with the port and size step: this 300-size unit carries a 1/2 in NPT port, and moving up or down a size (200/400/600) changes both the port and the flow capacity, so match the step to the air demand of the circuit. Because flow is published as curves rather than a single rated figure, ask us to confirm sizing against your application before ordering. The differential-pressure drain on this unit suits continuous-flow lines; choose manual drain (code M) for intermittently used circuits or automatic drain (code A) where unattended condensate removal is wanted. The standard 40 um element protects most pneumatic tools and actuators; specify the 5 um W-grade element where finer filtration is needed. The fitted square gauge here reads in bar; MPa and psi scales are also available, and an external round gauge is optional. PT is the standard thread, with G and NPT as order options, and a mounting bracket can be added if this no-bracket (J) configuration does not suit your panel.
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 rather than a single rated figure, so we do not quote one number here. Tell us your application and we will confirm the flow figures from the datasheet on request, so you can size the unit against your actual air demand before ordering.
The blank drain position on this code is the differential-pressure type, which uses the airflow itself to discharge collected condensate, suiting lines that run continuously. If your circuit works intermittently or you want fully unattended drainage, the same unit is available with a manual drain (code M) or an automatic drain (code A).
