2026-07-27Bought this modal-density duct silencer for 6042 hours
Have had the Sundrel Vault 981 in service long enough to say something useful about this modal-density duct silencer. Everything came down to service interval, and 6042 hours is what we needed. At 6042 hours it does not need to stand out anywhere else.

2026-07-17Good, with one reservation about the Sundrel Vault 981
The Sundrel Vault 981 was not the cheapest modal-density duct silencer we considered, and that was fine. The Sundrel Vault 981 shipped without the mounting hardware we had assumed was included. It has not changed what we think of the Sundrel Vault 981 overall.

2026-07-12Commissioning the Sundrel Vault 981
Went through the whole modal-density duct silencer catalogue twice before the Sundrel Vault 981. We had the Sundrel Vault 981 working before lunch, though the instructions did not help much. That is the whole of it, on the Sundrel Vault 981 at least.

2026-07-09Airflow at 1317 cubic metres per hour, as listed
Shortlisted three modal-density duct silencer units and the Sundrel Vault 981 was the one we kept. The figure that mattered was the airflow: 1317 cubic metres per hour. At 1317 cubic metres per hour it does not need to stand out anywhere else.

2026-07-06Two seasons with the Sundrel Vault 981
The Sundrel Vault 981 is our third modal-density duct silencer and the first one specified properly. Two seasons in, the Sundrel Vault 981 has not needed anything we did not plan for. We would put another Sundrel Vault 981 in without much thought.

2026-06-30Better than what we ran before the Sundrel Vault 981
Bought the Sundrel Vault 981 after a long comparison against the rest of this modal-density duct silencer shortlist. We ran something older in this role before the Sundrel Vault 981 and would not go back. That is the whole of it, on the Sundrel Vault 981 at least.

2026-06-27Filtration rating um of 10 micrometres was the deciding figure
We looked at most of the modal-density duct silencer listings before settling on the Sundrel Vault 981. What decided it was the filtration rating um at 10 micrometres. At 10 micrometres it does not need to stand out anywhere else.
