Description
Antminer S19 shroud, 8-inch outlet, full chassis-end wrap
Capture and carry are two separate problems. This Antminer S19 shroud solves both: a shell that encloses the whole exhaust end of the chassis, and a 203.2 mm collar wide enough that the run downstream never becomes the reason the heat stays in the room.
It is the configuration for an install that has somewhere specific to send the exhaust — through a wall, into a workshop, up to a heat-recovery loop, out a window on the far side of the room. Long routes, elbows and inline fans all take their cut of what the fans produce, and starting the run at 8 inches is the one decision that buys headroom for all of them at once.
One continuous PETG shell, drawn in-house, 296.8 mm across and 190 mm tall.
What it fits: S19 chassis end, 8-inch ducting
Wraps the complete exhaust end of the Antminer S19 and the S19 XP rather than sitting on the two 120 mm fan flanges, and terminates in a standard 8-inch collar that mates with 8-inch inline fans, couplers, elbows and window ports without an adapter.
In a shallow rack the 6-inch wrap is the more compact body.
How it installs
- Slide the shell over the exhaust end of the chassis and seat it square.
- Clamp 8-inch duct, or an 8-inch inline fan, straight to the collar.
- Confirm the 296.8 × 213.5 × 190 mm envelope clears the rack and the wall.
- Keep the first stretch of duct straight, then use long-radius elbows for the turns.
Why full capture and a wide collar belong together
Enclosing the chassis end removes the easy escape paths, which means more of the machine’s output now has to go through the collar. Pairing that with a narrow duct would move the restriction from the shroud to the pipe and hand back part of what the wrap just gained. Eight inches keeps the wide part wide from the chassis all the way to the penetration.
Downstream matters as much as the collar. A long-radius elbow turns air at a fraction of the pressure cost of a tight mitred bend, and 8-inch fittings let you route around a room without stacking losses. If the last opening in the wall is 6 inches, reduce there — at the end, where the air has already done its travelling.
- Encloses the full S19 exhaust end and exits through a full 8-inch collar
- Built for long runs, multiple bends, inline fans and shared trunks
- Mates directly with 8-inch hardware — no step-down at the machine
- Removes the corner and edge spill a fan-face shroud leaves behind
- PETG shell that holds its shape under continuous exhaust heat
- Single continuous piece with no seam to leak at the shoulder

Frequently asked questions
Why this over the 6-inch wrap?
Because the point of a full wrap is to send all of the heat somewhere deliberate, and a 6-inch pipe on a long, bendy route works against that. Take the 6-inch wrap when the exit is close, straight and space is tight; take this one otherwise.
Can I put an inline fan on this run?
Yes, and an 8-inch collar is the right place to start if you plan to. Clamp the fan to the collar directly or put a short length of duct between the two so the fan is not hanging off the machine. Boost the run, do not restrict it — the fan should be pulling through duct at least as wide as the collar.
What if my wall opening is only 6 inches?
Run 8-inch from the shroud and drop to 6-inch at the penetration with the 8″ to 6″ duct reducer. Necking down at the far end of a run costs much less than starting narrow at the collar.
Can I duct the power supply into the same line?
Not through this body. On the S19 the power supply sits beside the chassis rather than inside it, outside the plane this wrap encloses, so it takes a duct of its own rather than sharing this collar.
Will it fit a rack shelf?
Measure first: the body occupies 296.8 × 213.5 × 190 mm. It is one of the larger bodies in the line and shelf spacing on shop-built racks varies wildly.
