The AirTAC GFR30015AJF2WG AirTAC Filter Regulator G1/2 5 um Auto Drain 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 automatic 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 GFR300-15G is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This configuration carries a G1/2 (BSPP) port, a 5 um filter element for finer filtration than the standard 40 um grade, an automatic drain that expels collected condensate without operator attention, and an embedded square gauge reading in psi. The standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). The bowl is polycarbonate; only size 600 units use an aluminium alloy bowl.
This is a genuine AirTAC part. The GFR series is offered in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, a choice of PT, G or NPT thread, manual, automatic or differential-pressure drains, 40 um or 5 um elements, and square or round gauges in MPa, psi or bar scales. Flow is published as curves rather than a single rated figure, so ask us to confirm datasheet and sizing figures for your application before ordering. No mounting bracket is fitted on this version (code J); a bracket is available as an option.

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.

| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |

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.

Filtered, regulated air keeps gripper cylinders on a robotic assembly cell cycling at a consistent set pressure, with the 5 um element protecting seals and valve spools from fine particulate.
A spray-booth supply line benefits from 5 um filtration to keep moisture and debris out of the finish, while the regulator holds a steady atomizing pressure at the gun.
On a carton-sealing or wrapping line, this unit feeds sealing jaws and pusher cylinders with clean air at a fixed pressure so package dimensions stay consistent through the shift.
Size and port set the capacity: this is a size 300 unit with a 1/2 inch port; step up to 400 or 600 when air demand outgrows the line, or down to 200 for compact circuits. Because flow is published as curves rather than a single rating, send us your demand and we will confirm the right size before you order. Drain choice matters: automatic (this unit) clears condensate on its own, manual relies on operator action, and the differential-pressure default drains as the element loads up. Filter grade is 5 um here (code W) against the 40 um standard. The fitted square gauge reads psi; MPa and bar scales and an external round gauge are options. Thread is G (BSPP) on this unit, with PT as standard and NPT orderable; no mounting bracket is fitted.
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 G-series flow as curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure and air demand and we will confirm the flow from the datasheet for this G1/2, 5 um configuration before you order.
This unit's automatic drain expels collected condensate on its own, which suits unmanned or hard-to-reach installations. A manual drain (code M) needs an operator to open it, and the differential-pressure default drains as the element loads up. Regulation range follows the drain type: automatic and differential-pressure units adjust 0.15-0.9 MPa (20-130 psi), while manual-drain versions adjust 0.05-0.9 MPa (7-130 psi).
