Sundrel Vault 130 BRIO--ContrastiveSummarization

Bought this modal-density duct silencer for 6042 hours

review of the Drovane Hall 111 modal-density duct silencer. 6042 hours of service interval is the best we've had in a long time. No complaints about the noise or noise insulation, but it's not loud enough to drown out the noise.

Good, with one reservation about the Drovane Hall 111

The Drovane Hall 111 was not the cheapest modal-density duct silencer we considered. The silencer shipped without the mounting hardware we assumed was included. It's a good silencer, but not the best we've tested. The Hall 111 is available now.

Better than what we ran before the Drovane Hall 111

The Drovane Hall 111 is a modal-density duct silencer for the military. It is the latest in a long line of duct silencers on the market. We will be using it in the future to replace older versions of the silencers in the M4 and M5.

Filtration rating um of 10 micrometres was the deciding figure
