The AirTAC GFR300C15JF2W AirTAC Filter Regulator 300, PT1/2, 5 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 See datasheet 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.
GFR300C15JF2W is an AirTAC GFR300 filter regulator: filtration and pressure regulation combined in one body. It removes water and particulate from compressed air and holds a set downstream pressure, so one unit conditions and controls the supply at a 1/2 inch PT port. This configuration carries the 5 um filter element (code W) instead of the 40 um standard, a differential-pressure drain, an embedded square gauge reading in psi, the standard regulator type, and no reverse/check valve. It is supplied without a mounting bracket (code J). The regulator adjusts across 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -5 to 70 C, non-freezing. At size 300 the bowl is polycarbonate (PC).
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and offers manual, automatic or differential-pressure drains, 40 um or 5 um elements, square or external round gauges with MPa, psi or bar scales, PT, G or NPT threads, and bracket or no-bracket mounting. Flow is published as curves rather than a single rated figure, so we confirm datasheet and sizing figures 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 a pneumatic stamping or forming press: the 5 um element strips water and fine particulate before the main valve, while the regulator holds steady cylinder pressure for repeatable forming strokes.
Supplying fixture clamps and tool-change cylinders on a machining centre, where conditioned, regulated air keeps clamping force consistent from part to part.
Conditioning air for diverters, labellers and stopper cylinders on a packaging or bottling line, so moisture carryover does not upset valves mid-shift and line pressure stays where it was set.
Size 300 with a PT1/2 port sits mid-range in the GFR line; step up to 400 or down to 200 if your application's flow curve calls for it - we confirm sizing against the published curves before you order. The drain here is differential-pressure, which pairs with a 0.15-0.9 MPa (20-130 psi) regulation span; a manual-drain variant widens adjustment down to 0.05 MPa (7-130 psi). Code W selects the 5 um element for points of use that see finer contamination than the 40 um standard. The fitted square gauge reads psi; MPa and bar scales, and an external round gauge, are order options. Thread is PT as standard with G and NPT available as order options, and this unit is supplied without a mounting bracket - order the bracket variant if you mount it to a panel or wall.
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 GFR300 flow as curves rather than a single rated figure, so we do not quote a number here. Send us your operating pressure and air demand and we will confirm the flow from the datasheet on request before you order.
The W in this model code selects the 5 um filter grade, which captures finer particulate than the 40 um standard for sensitive downstream components. If your application does not need fine filtration, the 40 um default keeps the element loading slower; both grades are available across the GFR range.
