The AirTAC GFR30015JF2G AirTAC Filter Regulator G1/2, 40 um 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 GFR30015JF2G is an AirTAC GFR300 filter regulator: a single body that first removes water and particulate from compressed air, then regulates downstream pressure. This configuration carries a G1/2 (BSPP) port, the standard 40 um filter element, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, an embedded square gauge reading in psi, and the standard regulator type. It ships without a mounting bracket, so plan your mounting plate or bracket order separately.
This is a genuine AirTAC part in the GFR300 size, one of four frame sizes (200/300/400/600) that step up in port and flow capacity. Across the GFR range you can order a 5 um element (code W), automatic or manual drain instead of the differential-pressure default, PT or NPT threads, an external round gauge, and a bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet numbers 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.

On a machining cell where fixtures and clamps cycle all day, this unit cleans the shop air of water and swarf-carrying particulate and holds a steady regulated supply to the clamp cylinders, so grip force stays consistent from the first cycle to the last.
On a carton packing line, air cylinders and grippers need dry, particle-free air at a fixed pressure to place product accurately. This filter regulator mounted at the line drop conditions the supply and lets the technician set and read the working pressure in psi on the built-in gauge.
Spray guns and air-driven agitators in a finishing line are sensitive to water and dirt in the supply. This unit filters the air ahead of the booth and regulates it to the pressure the gun manufacturer specifies, with the differential drain carrying off collected moisture during operation.
Size the unit by the port and flow step: the GFR300 with its 1/2 in port sits mid-range between the 200 and 400 frames, so move up or down a size if your line demand sits clearly above or below it. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. Choose the drain to match maintenance habits: differential-pressure (this unit) needs no attention, automatic drains on a schedule of use, and manual drain suits attended stations - note that the drain choice also sets the regulation window, with this configuration regulating 0.15-0.9 MPa (20-130 psi). Element choice is 40 um standard or 5 um (code W) for finer protection; gauge scale can be MPa, psi or bar; thread can be PT (standard), G or NPT; a bracket is optional and not included on this code.
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 as curves, not as a single rated figure, so we do not quote a number that could mislead your sizing. Tell us your line demand and working pressure and we will confirm the right size from the datasheet curves before you order.
The differential-pressure drain (the default on this code) bleeds condensate from the bowl automatically as air flows through, with no operator attention. If you prefer, the GFR300 is also available with an automatic drain (code A) or a manual drain (code M); note that the manual-drain version widens the regulation range down to 0.05 MPa, while this configuration regulates 0.15-0.9 MPa (20-130 psi).
