VentCool Summit S-Class Series Whole House Fans

Summit S-Class Series Whole House Fans / Attic Fans offer free cooling by replacing hot indoor air with cool outdoor air.

Summit S-Class Series Whole House Fans are energy efficient, quietly performing residential cooling systems. Free cooling mode uses up to 90% less energy than air conditioning mode. A Summit S-Class Series attic fan or whole house fan provides up to 30+ air changes per hour depending on fan selection and size of house. A precooled house greatly reduces air conditioning use during the day.

Summit S-Class Series fans feature a highly efficient Electronically Commutated Motor (ECM) motors that operates at an optimally low cfm/watt draw consuming up to 90% less energy than traditional air conditioning. Summit S-Class models also feature an exclusive AirLoc Gravity Damper, a precise sealing system component designed for a secure precise seal to isolate the attic from the living space when operation for whole house fan is not desired. There are three Summit S-Class Series house fans to meet any need.

The Summit S-Class comes with the WTT whole house fan wall control, a wall mounted timer and temperature control. The WTT wall control controls the wholehouse fan using temperature or timer control. Temperature control optimizes your comfort and energy savings by never overcooling the your home and only running the fan when needed. The optional WLM-RTT Wireless Whole House Fan Remote Control is compatible with the Summit S-Class Series with the WFW Plug-In WiFi Module.

Summit S-Class Series whole house fans are rated and tested to Home Ventilation Institute Standard HVI-916 and can be used to comply with 2016 Title 24 Part 6. These house fans are also eligible for the Home Energy Renovation Opportunity (HERO) financing program. The HERO Program is an energy efficient financing program.

What is the difference between a whole house fan vs attic fan? Attic fans help prevent the transfer of heat from a hot attic to the living space below. An attic fan is installed in the attic and blows hot air from the attic out through a roof-level vent. Using an attic fan can reduce the temperature in the attic by up to 50 degrees and reduce the temperature by as much as 10 degrees in the living space below the attic.

A whole house fan is installed in the ceiling, usually in a central location. The fan draws in cooler evening air through open windows and pulls warm air from the home’s living space, blowing it into the attic. Whole house fans can provide 30 to 60 air changes per hour depending on the home’s floor plan, the climate, and fan size. This results in enough air to cool a home in approximately one hour. Once the sun rises and outdoor temperatures increase, the fan is shut off and the windows are closed to preserve the cooler air until the evening.
