The AirTAC GFR30015AF2WG 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 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 GFR30015AF2WG is an AirTAC GFR300 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is built for G1/2 (BSPP) ports, carries the finer 5 um filter element (code W, against the 40 um standard), and drains condensate automatically, so it suits lines that run without an operator at the bowl. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, and an embedded square pressure gauge scaled in psi is fitted. The bowl on this 300 size is polycarbonate, and the mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options include manual or differential-pressure drains, the 40 um standard element, G or NPT threads, gauge scales in MPa, psi or bar, and a reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for 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.

Mounted at the drop of a packaging machine's air main, it cleans the supply to the case-erecting and sealing cylinders and holds a set working pressure so carton clamping stays consistent through the shift. The automatic drain keeps condensate off the valve stack without a daily bowl check.
Feeding the air cylinders that divert, stop and index product on a conveyor line, it strips water carried in from the compressor room and lets the line supervisor set one stable pressure for the whole station. The 5 um element protects the small control valves that trigger each divert.
Installed ahead of a quarter-turn actuator on a plant air header, it filters the actuation air and regulates it to the pressure the positioner expects. The psi-scaled square gauge gives operators a local reading at the valve, and the automatic drain suits a location visited only on rounds.
Size and port step up together: 300 sits mid-range, and this unit takes G1/2 ports; larger sizes move to 3/4 and 1 inch. Choose the drain to match duty: automatic (this unit) clears condensate without attention, manual needs an operator, and the default differential-pressure drain uses the pressure drop across the element. The 5 um element (W) filters more finely than the 40 um standard; pick it where downstream valves and cylinders need cleaner air. Gauge scale is psi here, with MPa and bar as order options, and an external round gauge can be specified instead of the embedded square one. The thread on this unit is G (BSPP); PT is the standard thread and NPT is an order option. A mounting bracket is included. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 flow for the GFR300 as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure and air demand and we will confirm the datasheet curve and check the sizing against your application before you order.
The A in the code means the bowl drains condensate automatically, which suits installations that run unattended or sit where the bowl is hard to reach. The catalogue alternatives are a manual drain, where an operator opens the bowl, and the default differential-pressure drain, which uses the pressure drop across the element. Drain choice is a decode option across the GF, GFR, GFC and GC families.
