Aircel AMS Centrifugal Water Separator, 25 to 1500 CFM, 1/4 to 3 in. NPT
Nothing in this separator wears out. There is no element to buy, no cartridge to swap, no annual kit. Air enters the AMS and is spun hard enough that bulk liquid is thrown against the wall of the cast aluminum body, a vortex breaker stops the separated water from being picked back up by the airstream, and a float drain dumps it. That is the whole machine. It is the cheapest water removal in a compressed air system and the one most shops skip.
Key specifications
- Body: cast aluminum alloy with a corrosion-resistant liquid-shedding finish
- Separation: centrifugal, with a vaned module and vortex breaker to prevent re-entrainment
- Drain: float-type condensate drain valve supplied as standard
- Consumables: none, no replacement components required
- Capacity range: 25 to 1500 SCFM
- Connections: 1/4 in. through 3 in. NPT

Where it belongs in the system
Downstream of the aftercooler and upstream of everything else. The aftercooler condenses the water, the separator removes it, and only then does air reach the dryer and the filters. Put a coalescing filter where a separator belongs and you will be buying elements every few weeks, because a 0.1 micron element is not a bulk-water device and blinds immediately when it is fed slugs of liquid. The economics are not close.
Sizing
Size on actual flow through that leg of the pipe, not on compressor nameplate. Centrifugal separators depend on velocity, so an oversized unit is genuinely worse than a correctly sized one: drop the air speed far enough and the spin stops throwing liquid out. Two sizes share a port connection in a couple of places on the ladder above, which is deliberate. Pick by CFM first, then confirm the thread matches your pipe.
