A fan shroud for the intake or exhaust side of your miner. It mounts over the existing fan and directs the airflow through a duct hose exactly where you need it: outside, into the next room, or for heat recovery in winter.

What You Need the Shroud For
In normal operation, your miner blows the hot exhaust air freely into the room. With the shroud, you connect one side to a duct hose and direct the air away in a controlled way. Most commonly it is used on the exhaust side to route the waste heat outside. But you can just as well mount it on the intake side to supply fresh air from outside. For both sides at the same time, we recommend the 2-piece set.
6 Inch or 8 Inch?
6 inch (150mm) is more compact and sufficient for most setups with short, direct duct runs.
8 inch (200mm) offers less air resistance — the fans have to work less, run quieter and last longer. Recommended for duct runs over 2 meters, bends or continuous operation.
Compatible Miners
Fits all Antminer models with 2× 140mm fans: S21+, S21 Pro, S21 XP, S23.
Not compatible with S19, S21 (base model) or older S19 variants (different fan size, 120mm) — for those, find the matching shroud here.

Made from PETG — heat-resistant, durable, and printed as solid material. Designed and manufactured in Germany.
Frequently Asked Questions
Do I need one or two shrouds?
One shroud is enough if you only want to route the exhaust side (hot air) outside through a duct hose. For both sides at the same time, there is the 2-piece set — cheaper than two single pieces.
Which duct hose do I need?
A flexible aluminum duct hose matching the chosen size — 150mm diameter for 6 inch, 200mm for 8 inch. Available in our hose selection or at your local hardware store.
Does the shroud also fit the standard S21?
No. The Antminer S21 (base model) has 120mm fans, the S21+/Pro/XP series has 140mm. For the standard S21 you need the S19/S21 shroud.
Does the shroud also fit Whatsminer?
No. Whatsminer models also have 140mm fans, but a different case design. For those, there is the Whatsminer shroud.
