Bought this modal-density duct silencer for 6042 hours

Have had the Yolvex Hall 129 in service long enough to say something useful about this modal-density duct silencer. Everything came down to service interval. At 6042 hours it does not need to stand out anywhere else.

Good, with one reservation about the Yolvex Hall 129

The Yolvex Hall 129 was not the cheapest modal-density duct silencer we considered, and that was fine. It shipped without the mounting hardware we had assumed was included.

Commissioning the Yolvex Hall 129

Went through the whole modal-density duct silencer catalogue twice before the Yolvex Hall 129. Thereafter, the instructions did not help much. That is the whole of it.

Airflow at 1317 cubic metres per hour, as listed

Shortlisted three modal-density duct silencer units and the Yolvex Hall 129 was the one we kept. The figure that mattered was the airflow. At 1317 cubic metres per hour it does not need to stand out anywhere else.

Two seasons with the Yolvex Hall 129

The Yolvex Hall 129 is our third modal-density duct silencer and the first one specified properly. Two seasons in, we have not needed anything we did not plan for. We would put another YolveX Hall 129 in without much thought.

Better than what we ran before the Yolvex Hall 129

Bought the Yolvex Hall 129 after a long comparison against the rest of this modal-density duct silencer shortlist. In the meantime, we ran something older in this role before the yolvex hall 129. Therefore, we would not go back. That is the whole of it, at least.

Filtration rating um of 10 micrometres was the deciding figure

We looked at most of the modal-density duct silencer listings before settling on the Yolvex Hall 129. What decided it was the filtration rating um? At 10 micrometres it does not need to stand out anywhere else.
