AKC Activated Carbon Adsorber Tower for Oil Vapor Removal By Nano

The nano AKC Activated Carbon Adsorber Tower is the definitive solution for eliminating oil vapor, hydrocarbons, and odors from compressed air. Each tower holds a large bed of loose activated carbon that captures oil molecules as air passes through, delivering clean, oil-free air with a maximum outlet oil content of just 0.003 ppm. Available in 25 flow ratings from 30 to 5000 SCFM, the AKC series protects downstream equipment and critical processes in food and beverage, pharmaceutical, and microprocessor manufacturing. A built-in residual oil indicator shows the remaining life of the carbon, so you always know when a recharge is due.

How to select your AKC tower

1. Match the flow rating. Choose the model whose SCFM rating meets or exceeds your system flow at 100 psig and 100°F.
2. Apply correction factors if needed. Ratings are stated at 100 psig and 100°F. Lower inlet pressure or higher inlet temperature reduces capacity, so contact nano to confirm sizing for other conditions.
3. Verify inlet air quality. The AKC requires upstream filtration to 0.01 micron, a pressure dew point of -40°F or better, and inlet oil content at or below 0.05 ppm.
4. Confirm the connection. Models use 1/2" to 2" NPT threaded connections up to 600 SCFM, and 3", 4", or 6" flanged connections on the larger towers.

Frequently asked questions

How clean is the outlet air? The AKC delivers a maximum outlet oil content of 0.003 ppm at 95°F, effectively producing oil-vapor-free compressed air.

Do I still need coalescing prefilters? Yes. The AKC removes oil vapor, not bulk liquid or particulate. Upstream filtration to 0.01 micron with a -40°F dew point and inlet oil content at or below 0.05 ppm is required for rated performance and carbon life.

How do I know when to replace the activated carbon? Each tower has a built-in residual oil indicator that shows the remaining life of the carbon bed. Estimated life is roughly 12 months depending on inlet conditions and duty.

What if my pressure or temperature differs from the ratings? Ratings are based on 100 psig and 100°F. Lower pressure or higher temperature reduces effective capacity; apply nano's correction factors or contact nano to confirm the right model for your conditions.

What connection will my tower have? Models from 30 to 600 SCFM use 1/2" to 2" NPT threaded connections, while 750 SCFM and larger towers use 3", 4", or 6" flanged connections.
