|#1||Q: Several questions do not seem to be addressed: 1. what it the blade size? 2. Can the system be duct-vented through the roof vs. directly into the attic? 3. What square footage coverage does this provide, on high and low speeds? 4. What are the dBa noise ratings at the two speeds? 5. What is the ceiling opening size?
A: There is no listed size of blade, but 16-18 inch seems likely...It shouldnt be ducted as that style fan doesnt do well in duct...High speed would cover 3000-3500 sq ft depending on area in country...No dB rating listed...Opening size is 14.5x22.5.

R38 insulated whole house fan. 2-Speed moving 1,150/1,600 CFM. Fits 16” or 24” on-center joists with no joist cutting.
The AirScape 4.4e WHF exhausts 4400 CFM and is extremely energy efficient (ECM motor). The damper doors close when the fan is off providing an insulated seal (R-49 on XR).
