We love houses, and so do our friends at Redfin – the very cool and informative real estate website. They just published this article , which has some great tips on keeping your house cool this summer.
Keeping you cool, while saving energy – that’s a core part of our business, so we’re happy to see our tip mentioned. And what do you know ? We suggested whole house fans.
We just got a patent on a technology that we’ve been using on our whole house fans. The use of motor aerodynamic motor mounts allows us to get an average of 17% more airflow.
How times change…
A few weeks ago we were ramping up our whole house fan production for the summer season. Now we are very busy making HEPA filtration units for hospitals, and yes, observing Covid safety protocols. Masks [check], distancing [check], good ventilation [check], doors open for extra air dilution [check], hand sanitizer [check], outdoor breaks in the sun [check]. We spent a lot of time writing procedures on how to stay safe.

What is the difference between a Whole House Fan and an Attic Ventilator? First of all the Whole House Fan is mounted in the attic, while an Attic Ventilator is mounted on the roof or the gable wall of an attic.
The Whole House Fan pulls in cool outside air when you open the windows at night and exhausts the stale, hot air out. It is a natural source of fresh air that saves energy. Because a WHF operates between 2000 CFM and 6000 CFM they quickly exhaust hot indoor air and bring in the cool outside air.
An Attic Ventilator’s purpose is to get hot air out of your attic and bring cool air in. However, it can be pulling that cool air from your house. The fan can depressurize the attic by exhausting air from it, as well. Replacement air comes in either from the outside intake vents or from openings/cracks into the house. The main reason to cool an attic is if you store things in it or have ductwork or HVAC equipment up there. If this is the case, your HVAC equipment and ductwork would better serve you in the interior of your home somewhere, or the insulation should be moved from the attic floor to the sloped roofing of your house.
As you can see the Whole House Fan is designed to cool your home and save you energy while the Attic Ventilator, while good in theory, can actually pull cool air from your home and in turn cost you more in energy.
Direct Vent System for Greenhouse and Warehouse Ventilation
Engineers here at AirScape are currently working on the finishing touches of a direct vent exhaust fan designed for industrial and commercial applications such as large indoor greenhouses and warehouses.
The system can be configured for roof or wall exhaust and has automatic Powered AirLock doors. There is an inlet louver with a Powered AirLock so that the space can be sealed up when no exhaust is desired.
Preliminary airflow testing is still incomplete because it outperforms our test chamber’s capacity… Well over 8500 cfm on only speed 6 (out of 10)! More data to follow as we recalibrate be able to accurately test such high airflow.
