What works

The official TPI instructions explicitly name CE 18-DS and its rough-in size
The manual covers this DS series' shutter orientation and wall-dependent fastening

What doesn't

No current first-party CE 18-DS performance table was retrievable
The manual says the wall-mounting hardware is not supplied

Who it's for

Good fit

A CE 18-DS replacement where an 18.50-inch square opening and shutter arrangement have been verified

Look elsewhere if

Selecting airflow, electrical load, speed count, or warranty from an unsupported listing claim

A model-specific opening requirement

TPI's commercial exhaust-fan installation instructions list CE 18-DS in the recommended rough-in table and specify an 18.50-inch square hole. The same document illustrates the shutter-mounted DS family and includes CE 10-DS through CE 30-DS in its installation instructions. That establishes the actual model family and a concrete opening requirement without treating the model name as a source for unverified airflow or electrical numbers.

TPI says wall mounting hardware is not included because wall applications differ. The instructions describe using fastening appropriate to wood, steel, or masonry construction and say a mounted shutter should open upward. Measure the existing opening and inspect the shutter condition before treating this as a drop-in replacement. Those details have a more direct effect on suitability than an old marketplace size phrase.

No currently retrievable first-party performance sheet was found for CE 18-DS. The manual does not publish the model's CFM, motor load, horsepower, number of speeds, cord configuration, dimensions, or outdoor rating. Those fields have been left unpublished. A model code or a stale catalog result is not a substitute for an available TPI document or the supplied unit's label.

CE 18-DS is a shutter-mounted exhaust format, not a free-standing circulation fan. The 18.50-inch rough-in requirement does not predict fan output after installation or a building's outdoor-air exchange. For a smaller opening in the same official manual, compare the CE 12-DS, listed with a 12.50-inch square rough-in. Obtain current model-specific performance information when airflow or circuit loading is a deciding factor.
