The AirTAC GFR40015JF2W AirTAC Filter Regulator PT1/2, 5 um 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 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 GFR40015JF2W is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 400-size unit is supplied with a PT1/2 (1/2 in) PT-threaded port, a 5 um filter element (the finer W grade, versus the 40 um standard), a differential-pressure drain that bleeds condensate automatically as flow passes through, an embedded square gauge scaled in psi, and the standard regulator with a 0.15-0.9 MPa (20-130 psi) adjustment range. No mounting bracket is included in this configuration.
This is a genuine AirTAC part from the GFR400 series, one of four sizes (200/300/400/600) spanning the G-series port range from 1/8 in to 1 in. Options across the series include automatic or manual drains, the 40 um standard element, G or NPT threads, alternative gauge scales, and a reverse/check valve. Rated flow is published as curves rather than a single figure, so we confirm flow and datasheet figures on request before you order.

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.

| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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.

Conditioning and regulating the air supply to a bench or C-frame pneumatic press, where the 5 um element protects directional valves and the regulator holds a steady working pressure stroke to stroke.
Serving a 1/2 in branch line on a cartoning or wrapping machine, feeding seal cylinders and vacuum generators with filtered, regulated air at a set point read locally in psi.
Regulating supply to conveyor stopper, pusher and diverter cylinders on a production line, with the differential-pressure drain keeping condensate out of the circuit during continuous running.
Size and port: the 400 size carries a 1/2 in PT port; step up or down (200/300/400/600) to match the pipe size and air demand of the line. Drain: this unit uses the differential-pressure drain (the default); choose the A code for fully automatic draining or M for manual where the duty differs. Filter grade: this configuration carries the 5 um W element for finer particulate removal; the blank code gives 40 um for general-duty air. Gauge: the square gauge here reads in psi; MPa and bar scales are available, and an external round gauge is optional. Thread: PT is standard; order G (BSPP) or NPT as options. Bracket: the J code means no bracket is fitted.
Because flow is published as curves rather than 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. 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 GFR400 series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure, set pressure and expected air demand, and we will confirm the flow and datasheet figures for this exact model on request before you order.
The W in the code GFR40015JF2W selects the optional 5 um filter grade, which removes finer particulate than the 40 um standard element. It suits downstream valves, cylinders and instruments that need cleaner air. If your application needs only general-duty filtration, the 40 um version of the same unit is available.
