The AirTAC GFR30015JF2WGK AirTAC Filter Regulator G1/2, 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 GFR30015JF2WGK is a 300-size filter regulator that removes water and particulate from compressed air and holds downstream pressure in one body. This configuration has G1/2 (BSPP) ports, a 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain that bleeds collected condensate automatically whenever the pressure drop across the element is high enough, an embedded square pressure gauge reading in psi, and a built-in reverse/check valve that holds downstream pressure when the supply is shut off. It ships without a mounting bracket, so plan to mount it by its ports or add a bracket separately. The standard regulator covers 0.15-0.9 MPa (20-130 psi) with this drain type, and the polycarbonate bowl suits the -5 to 70 C non-freezing operating range.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, and MPa, psi or bar gauge scales. Flow for this model is published as curves rather than a single rating, so ask us to confirm the datasheet figures against your application before ordering.

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.

Point-of-use air preparation for a stamping or assembly press: the 5 um element protects directional valves and clamping cylinders from water and swarf, while the regulator holds a steady clamping pressure and the check valve keeps the circuit pressurised during brief supply drops.
Clean, regulated air for the stopper, pusher and lift cylinders on a bottling or carton-packing conveyor, where the G1/2 port feeds a manifold of smaller take-offs and the psi gauge lets line staff set and verify the station pressure at a glance.
A wall-mounted service drop in a maintenance bay feeding paint guns and air blow-off nozzles: the filter-regulator removes pipe-scale and condensate ahead of the gun, the regulator sets a repeatable gun pressure, and the check valve prevents backflow when the drop is isolated.
Start with the port and size step: GFR300 with G1/2 threads sits mid-range in the family, so size up to GFR400 or GFR600 if your line needs more flow, or down to GFR200 for compact circuits - we will check the published flow curves against your demand on request. This unit already carries the finer 5 um element (code W); the catalogue alternative is 40 um standard filtration if your actuators do not need the finer grade. Drain is differential-pressure here, which needs no attention but only clears when the pressure drop is high enough; choose automatic drain (code A) for unattended condensate removal or manual (code M) where you want operator control. The square gauge reads in psi, and MPa or bar scales are available if you prefer. Thread is G (BSPP) on this model, with PT as the standard and NPT orderable; a mounting bracket can be added since this unit is supplied without one.
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 GFR300 series as curves, not as a single rated figure, so we do not quote a number. Send us your line pressure, downstream pressure target and air demand, and we will confirm the datasheet curves and check the sizing for your application before you order.
The W in the code GFR30015JF2WGK selects the finer 5 um filter grade instead of the 40 um standard, and F2 selects the embedded square gauge with a psi scale (MPa and bar scales are also catalogue options). The K adds a reverse/check valve, and J means no mounting bracket is supplied. All of these are orderable choices, so if you need 40 um filtration, a different gauge scale or a bracket, ask us for the matching GFR300 code.
