Genuine AirTAC air filter, order code AF2000W from the AF-BF range. The options this code selects are decoded below; series data follow the official AirTAC catalog.
The AF2000W is the fine-filtration version of AirTAC's A-line AF2000 filter: the W suffix in the order code substitutes the standard 40 um element for a 5 um element, capturing far finer particles in the same PT1/4-port body. The thread remains standard PT, so it bolts into typical PT1/4 pipework without adapters.
Filtration this fine protects sensitive components such as pneumatic sensors, small valves and precision actuators that bulk 40 um filtration does not fully shield. The 15 cc bowl handles 0.15 to 1.0 MPa (20 to 145 psi) working pressure with 1.5 MPa (215 psi) proof pressure, operates from -5 to +70 C with no freezing, and drains by differential plus manual action.

Choose the AF2000W when the application demands finer air quality than the standard element can deliver: plain AF2000 keeps the 40 um element, while this W code gives 5 um on the same PT1/4 port and PT thread. If your piping is G or NPT thread, the AF2000G and AF2000T siblings are the thread alternatives at the same 40 um level. When flow demand or bowl size outgrows the 15 cc A-line bowl, step up to BF2000 with its 40 cc bowl and B-line body.
A 5 um element ahead of pressure and position sensing circuits removes particles fine enough to disturb small orifice sensors that a standard 40 um element lets pass.
Supplies clean 0.15 to 1.0 MPa air to packaging machine sealing and dosing heads, where fine particle carry-over can mark product or foul needle nozzles.
On test rigs and lab benches built with PT1/4 fittings, the W option upgrades the supply element to 5 um while keeping the same manual-drain service routine.
Port: PT1/4, standard PT thread. Element: 5 um (the W option, versus the 40 um standard). Bowl capacity: 15 cc. Operating pressure: 0.15 to 1.0 MPa (20 to 145 psi). Proof pressure: 1.5 MPa (215 psi). Temperature: -5 to +70 C, no freezing. Fluid: air. Drain: differential plus manual.
The W suffix swaps the element from the 40 um standard to 5 um, so the filter captures finer particles downstream. Nothing else in the code changes: the port is still the AF2000 PT1/4 size with PT thread and the 15 cc bowl. Because finer elements clog faster than coarse ones, plan on more frequent checks of the differential-drain indicator and manual draining to keep the 0.15 to 1.0 MPa operating range stable.
