Canaan Cooler Box Shroud – 6-Inch or 8-Inch Exhaust Duct

Canaan Cooler Box shroud for your exhaust duct

The Canaan Cooler Box shroud connects a CryptoCloaks Nano 3 / Nano 3S Cooler Box to a round exhaust duct. It is a replacement part for the enclosure, not a complete cooler box or an adapter that mounts directly to an individual miner.

Match the box capacity first, then the duct outlet. The 2-unit and 4-unit versions are different parts; choosing a larger duct does not change which enclosure the shroud fits.

Choose your fit, outlet, and color

• Cooler Box Size: 2-Unit Cooler Box or 4-Unit Cooler Box.
• Duct Size: 6-Inch Duct or 8-Inch Duct.
• Color: Black, Orange, White, or Yellow.

Each selection is for one shroud with one outlet diameter. Check the size of your existing duct before ordering rather than assuming either version will connect to it.

Compatibility and package contents

This part fits the CryptoCloaks Canaan Nano 3 / Nano 3S Cooler Box. Compatibility follows the enclosure capacity, whether your setup uses Nano 3 or Nano 3S miners. It is not a standalone Avalon Q shroud or a universal adapter for other enclosures.

Included: one exhaust shroud in your selected box fit, outlet size, and color.

Not included: cooler box, miners, fans, fan controller, mounting hardware, flexible duct, hose, or clamps. A complete setup pictured on the listing does not change those contents.

Before connecting the duct

1. Power down and unplug the miners and fans before working on the enclosure.
2. Check the shroud against the correct box opening without forcing the printed part.
3. Connect matching ducting and support the run separately so its weight does not hang from the shroud.
4. Keep the airflow path open and check temperatures and fan behavior after restarting.

A shroud routes exhaust; it does not generate airflow or guarantee lower temperatures. Duct length, bends, restrictions, and the enclosure’s fans still matter. Stop and check the setup if airflow or operating temperatures change unexpectedly.

Frequently asked questions

Does this include the complete Cooler Box?

No. This listing includes one replacement exhaust shroud only. The enclosure and its other components are not included.

How do I choose the box size?

Match the 2-unit or 4-unit option to the CryptoCloaks Cooler Box you own. Those shrouds are not interchangeable.

Does one shroud fit both duct sizes?

No. Select either the 6-inch or 8-inch outlet to match your ducting.
