The AirTAC GFR30015JF2WTK AirTAC Filter Regulator NPT1/2 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 GFR30015JF2WTK is a 300-size filter regulator that removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration carries a 1/2 in NPT port, a 5 um filtration element for finer air than the standard 40 um grade, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, an embedded square gauge reading in psi, and a built-in reverse/check valve that holds the downstream setting if upstream supply is interrupted. It is supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjustment range with differential-pressure drain is 0.15-0.9 MPa (20-130 psi), and the operating temperature is -5 to 70 C (non-freezing). The polycarbonate bowl suits 200/300/400 sizes; only size 600 uses an aluminium alloy bowl.
This is a genuine AirTAC part. The GFR family is available in 200, 300, 400 and 600 sizes with port options from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, gauge scale in MPa, psi or bar, and PT, G or NPT threads. Flow for this series is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application 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.

Feeds and regulates the clamp cylinders on a CNC fixture, with the 5 um element protecting fine seal surfaces and the check valve holding clamp pressure if the main supply drops.
Supplies regulated air to the cylinders that divert cartons and actuate heat-seal jaws, with the psi gauge letting operators set and verify line pressure at a glance.
Sits at the take-off point of a plant air header feeding a workstation, filtering condensed water out of the supply and setting a stable pressure for hand tools and small actuators.
Start with the port and size: this unit steps up to 1/2 in NPT on the 300 body, so match it to the line size and the air demand of the circuit it feeds. Choose the drain to suit access: differential-pressure (as fitted here) needs no attention during operation, automatic drains condensate on a cycle, and manual drain suits attended installations. This unit carries the 5 um (W) element; the 40 um standard grade remains available if coarser, longer-life filtration is preferred. The embedded square gauge is set to a psi scale here, with MPa and bar scales and an external round gauge as alternatives. Thread is NPT in this code; PT is the standard and G is also an order option. A mounting bracket can be added if this no-bracket version needs panel fixing.
One honest note before ordering: flow for GFR units is published as curves, not a single rated number, so send us your air demand and we will confirm the correct size against the datasheet before you commit.
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 the GFR series as curves rather than a single rated figure, so we do not quote a number here. Send us your air demand and line conditions and we will confirm the datasheet flow data for this 300-size, 1/2 in unit on request.
The W in the code selects the optional 5 um filtration grade, which captures finer particles and carries less water through to downstream valves and cylinders than the 40 um standard element. The trade-off is a denser element, so if your application tolerates coarser air, the 40 um version of the same unit is available to order.
