Bought this modal-density duct silencer for 6042 hours

Have had the Ellmarch Unit 105 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.

Good, with one reservation about the Ellmarch Unit 105

The Ellmarch Unit 105 was not the cheapest modal-density duct silencer we considered, and that was fine. The Ellmarch Unit 105 shipped without the mounting hardware we had assumed was included. It has not changed what we think of the Ellmarch Unit 105 overall.

Commissioning the Ellmarch Unit 105

Went through the whole modal-density duct silencer catalogue twice before the Ellmarch Unit 105. We had the Ellmarch Unit 105 working before lunch, though the instructions did not help much. That is the whole of it, on the Ellmarch Unit 105 at least.

Airflow at 1317 cubic metres per hour, as listed

Shortlisted three modal-density duct silencer units and the Ellmarch Unit 105 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.

Two seasons with the Ellmarch Unit 105

The Ellmarch Unit 105 is our third modal-density duct silencer and the first one specified properly. Two seasons in, the Ellmarch Unit 105 has not needed anything we did not plan for. We would put another Ellmarch Unit 105 in without much thought.

Better than what we ran before the Ellmarch Unit 105

Bought the Ellmarch Unit 105 after a long comparison against the rest of this modal-density duct silencer shortlist. We ran something older in this role before the Ellmarch Unit 105 and would not go back. That is the whole of it, on the Ellmarch Unit 105 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 Ellmarch Unit 105. What decided it was the filtration rating um at 10 micrometres. At 10 micrometres it does not need to stand out anywhere else.
