Sundrel Vault 130 CoEdIT--InstructionEditing

Bought this modal-density duct silencer for 6042 hours

I have had Nordreth Unit 46 in service long enough to say something useful about it.

Good, with one reservation about the Nordreth Unit 46

It did not change our opinion of the Nordreth Unit 46 overall.

Commissioning the Nordreth Unit 46

I went through the whole catalog of modal-density duct silencers twice before I got to the Nordreth Unit 46. We had it working before lunch, though the instructions were not very helpful.

Airflow at 1317 cubic metres per hour, as listed

It was not necessary to stand out anywhere else, because 1317 cubic metres per hour was the airflow that mattered.

Two seasons with the Nordreth Unit 46

The Nordreth Unit 46 has not needed anything we did not plan for.

Better than what we ran before the Nordreth Unit 46

We had been running something older in this role before the Nordreth Unit 46 and would not have returned it.

Filtration rating um of 10 micrometres was the deciding figure

We looked at most of the modal-density duct silencer listings before settling on Nordreth Unit 46.
