What You Need This Set For
In standard operation, your miner blows hot exhaust air freely into the room — and draws in unfiltered room air on the other side. With the 2-piece set, you connect both sides to duct hoses. This lets you supply fresh air from outside and direct the heat wherever you need it — outdoors, into another room, or to supplement heating on cold days.

Frequently Asked Questions
Can I cover just one side?
Yes, you can start with just the exhaust side and install the second shroud later. If you only need one side, the single shroud is the more affordable option.
Which duct hose do I need?
A flexible aluminum duct hose with 150mm diameter (6 inch). Available in our hose selection or at your local hardware store.
Difference from the Universal Set S19-8?
The Universal Set (S19-8) additionally includes a PSU adapter and is designed for 8 inch hoses. It also supports operation without stock fans (external cooling). This 2-piece set is the straightforward solution for covering both sides with 6 inch hoses while keeping the stock fans in place.
6 inch or 8 inch — which is better?
6 inch (150mm) is more compact and works for most setups. 8 inch (200mm) offers less airflow resistance — fans run quieter, work less hard and last longer. Recommended for longer duct runs, bends or continuous operation.
