The AirTAC GFR30015AJC2W 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 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 GFR30015AJC2W is a GFR-series filter regulator: it removes water and particulate from compressed air and holds a steady downstream pressure in a single body. This unit is built on the GFR300 size with PT1/2 (1/2 in) PT-threaded ports, a 5 um filter element (code W), an automatic drain that expels collected condensate without manual attention, and a round pressure gauge reading in psi. It is ordered without a mounting bracket and without a reverse/check valve, and its standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of PT, G or NPT thread, differential-pressure, automatic or manual drains, 40 um or 5 um filtration, and gauge options. The working temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing for your application.

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.

Filtering and regulating the air feeding a carton-sealing or wrapping line, where clean air at a set pressure keeps cylinders and vacuum generators cycling consistently, and the automatic drain clears condensate between shifts.
Conditioning the air supply to pneumatic clamps on a machining cell, where the 5 um element protects the fixture valves and the regulator holds the set clamping pressure part after part.
Preparing the air that drives diverters and stoppers on a warehouse sortation conveyor, with filtered, regulated supply and automatic condensate draining to keep the downstream valves working cleanly.
The real choices within GFR are the size and port (200/300/400/600, 1/8 to 1 in) matched to the air demand of the circuit; the drain type (differential-pressure as standard, automatic, or manual); the filter grade (40 um standard, 5 um with the W code for finer protection); the gauge style and scale (embedded square or external round, MPa/psi/bar); the thread (PT standard, G or NPT to order); and whether a bracket is fitted. This GFR30015AJC2W takes the 1/2 in port, 5 um element, automatic drain, round psi gauge and no bracket. Flow is published as curves, not a single rated figure, so send us your application details and we will confirm sizing against the datasheet before you order.
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 GFR performance as flow curves rather than a single rated figure, so we do not quote a number. Tell us your application and we will confirm the flow data from the datasheet on request.
The W code selects the 5 um element instead of the 40 um standard, giving finer protection for downstream valves and cylinders, and the A code selects an automatic drain that expels condensate without manual attention. Both are standard catalogue options, so a 40 um element or a manual drain can be ordered instead if you prefer.
