The AirTAC AirTAC GFR30015JF2TK Filter Regulator NPT1/2 psi 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 GFR30015JF2TK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is size 300 with a 1/2 in NPT port, a 40 um standard filter element and a differential-pressure drain, and it is fitted with an embedded square gauge scaled in psi and a reverse/check valve; no mounting bracket is included. It handles a maximum inlet pressure of 1.0 MPa (145 psi), operates from -5 to 70 C (non-freezing), and adjusts outlet pressure from 0.15 to 0.9 MPa (20-130 psi). The bowl is PC (polycarbonate) at this size.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, PT, G or NPT threads, manual, automatic or differential-pressure drains, 40 um or 5 um (W) filtration, and MPa, psi or bar gauge scales. Flow is published as curves rather than a single rating, so ask us to confirm datasheet figures for your application.

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.

Filtering and regulating the air feeding directional control valves and cylinders on a carton-forming line, so actuators see clean air at a set pressure.
Conditioning the supply to a pick-and-place robot cell, where the regulator sets consistent gripping pressure and the 40 um element shields the gripper circuit.
Supplying regulated air to stopper, pusher and lift cylinders along a conveyor line, with the check valve holding the set downstream pressure.
Size and port set the capacity: this unit is size 300 with a 1/2 in NPT port; step up to size 400 or 600 for larger demand, or down to size 200 for compact lines. Choose the drain: differential-pressure (this unit, the standard), automatic (A) for unattended condensate removal, or manual (M) for periodic service - note the manual-drain version regulates from 0.05 MPa, while this differential-pressure unit adjusts 0.15-0.9 MPa (20-130 psi). Filtration is 40 um standard; specify W for 5 um where finer protection is needed. Gauge scale (MPa, psi or bar), PT vs G/NPT thread and the optional bracket are order choices, as is the reverse/check valve (K). Flow is published as curves, not a single rating - ask us to confirm sizing against your application before ordering.
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 this family as curves, not as a single rated figure, so we do not quote a number on the page. Tell us your port size and application and we will confirm the flow and full datasheet figures on request before you order.
K means a reverse (check) valve is fitted, so this unit differs from the standard GFR300 build, which has no check valve. Other decodable choices on this unit are the 1/2 in NPT thread (PT is standard, G and NPT are order options), the psi-scaled square gauge, the 40 um element and the differential-pressure drain.
