Bought this modal-density duct silencer for 6042 hours

Has had the Drovane Frame 47 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 Drovane Frame 47

The Drovane Frame 47 is not the cheapest modal-density duct silencer we considered, and that was fine. The Drovane Frame 47 shipped without the mounting hardware we had assumed was included. It has not changed what we think of the Drovane Frame 47 overall.

Commissioning the Drovane Frame 47

went through the whole modal-density duct silencer catalogue twice before the Drovane Frame 47. We had the Drovane Frame 47 working before lunch, though the instructions did not help much. That is the whole of it, on the Drovane Frame 47 at least.

Airflow at 1317 cubic metres per hour, as listed

Shortlisted three modal-density duct silencer units and the Drovane Frame 47 is 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 Drovane Frame 47

The Drovane Frame 47 has not needed anything we did not plan for. We would put another Drovane Frame 47 in without much thought.

Better than what we ran before the Drovane Frame 47

bought the Drovane Frame 47 after a long comparison against the rest of this modal-density duct silencer shortlist. We ran something older in this role before the Drovane Frame 47 and would not go back. That is the whole of it, on the Drovane Frame 47 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 Frame 47. The filtration rating um at 10 micrometres. At 10 micrometres it does not need to stand out anywhere else.
