QA 3300 Pro whole house fan with smart control

QA-Deluxe whole house fans are quiet, and energy efficient. They are modern, ducted fans that hang from the rafters in the attic. They are connected to the ceiling grille with flexible, insulated duct. This keeps the fan noise away from the ceiling opening. They have insulated dampers that close when the fan turns off. The insulation is much better than other fans. The fan body is heavy spun aluminum and there are rubber bushings on the motor mounts to help prevent vibration.
These fans all include a 2 speed control switch and a smart switch that works with Google or Alexa.
We stock the Pro Elite line which has a 15 year warranty and also has removable ceiling grilles.
They come in three sizes -

• The QA 3300 is good for homes up to 1700 sf.
• The QA 5500 is good for homes up to 2800 sf.
• The QA 6500 is good for homes up to 3200 sf.
