Case Studies

Over the years since 2008 we have sold several very interesting systems with different configurations that I think might be of interest to you. Many of our systems have used large 30 inch and 36 inch blades connected to multiple ducts pulling air from many rooms. Here are a few examples.

LONGMONT
David in Longmont has a large home with bedrooms at both ends. He needed a large machine capable of pulling a lot of air. He chose a fan pulling 10600 CFM with a 36 inch blade and 4 duct connectors for 4 inlet locations. We designed a new duct collector box for this home to maximize air flow and minimize duct air resistance. Here is a picture of one half of the duct collector box.

This shows one half of the box with two of the 4 18 inch duct collars and the venturi.

The collector box is made in two sections so that it can be lifted up into almost any attic hatch. This box measures about 40 inches long, 20 inches wide and only 10 inches thick.

Here is another picture of it assembled with the side brace bolted in place.

The belt drive machines have thin frames and a spring loaded, hinged motor.

The larger systems have belts that are spring loaded so that the belt tension is always perfect. This reduces maintenance dramatically.

INDIANAPOLIS
One of our first long distance installations was for Paul and Mary in Indianapolis, Indiana. Paul was sold on our speed control and infinitely variable speed motor. The third feature he and Mary liked was the portable remote on off control. He asked me to recommend an installer and I introduced him to Doc’s Electric. They installed it in June 2012 and it worked perfectly.

GUNBARREL
David called in May 2013 to ask about how to cool his large ranch home with bedrooms at both ends of the long structure. He first thought about putting in two systems – one at each end. After talking about how air will move from any part of the house to any other part as long as the doors are open, he decided to put in one 36 inch system. Since he is in cold country he also decided to really insulate the ceiling openings with the optional R60 dual dampers. I introduced him to VentMasters for installation.

YUCAIPA
Our first 30 inch rafter mounted system was for Adam who bought a new house for his wife and new baby – a one story with a big attic. He had a 30 inch in his previous home but it was in the hall ceiling and noisy. He wanted our quiet and powerful 30 inch up hanging off the rafters. We installed it in October, 2011 with two 18 inch ducts connected to his family room and a hallway. He went into his master bedroom, opened a window, and the wind blew the leaves on a faux tree 10 feet away. He commented that the sound was “not as much as his air conditioner”. By the way, this was a direct drive fan blade so it was not as quiet as our new belt driven blades.

This system is nearly identical to the one below we installed for Gearard. The difference was that Adam does not have splitters for 4 14 inch ducts, he has 2 18 inch openings instead.

MURRIETA
In 2012 I was called by Gearard who asked if I could install a 30 inch hall ceiling system he just bought at Orchard. I told him about the system in Yucaipa and he decided that was what he wanted. He and I both worked to install it and connect ducts to his 4 upstairs bedrooms. Again, this was a direct drive, not belted. When we turned it on it pulled a wind through his window that blew the curtains sideways.

Here is a picture of the central fan assembly. It has 2 18 inch duct collars. Those 2 18 inch ducts were connected to splitters that reduced each 18 inch duct to two 14 inch ducts for 2 rooms upstairs. So there were 4 total ceiling openings each 14 inches in diameter.

BANNING
Richard called in 2014 to ask about his home – a single story with a large great room with vaulted ceilings. I visited him and we talked about where to install ceiling openings. He decided to put one in the kitchen at the far right of the home, one high on the wall over the great room, one in a den at the far left and one in a hall at the far left. He decided on the latest belt driven 6 bladed 36 inch machine for optimum air flow. We then talked about gable venting and gable fans (also called attic fans). We decided to use the power of this new fan to sweep the hot air out of the attic and the less hot air in from a gable fan at the left end of his attic. So during the hot day this whole house fan will be used as a powerful gable fan and pull outside air into the attic from the gable vent which will keep the attic no hotter than outside. As you know, the sun heats up the roof which overheats the air in the attic and that heats up the ceiling which heats up the house. This unique system will reduce the ceiling temperature dramatically.

DE LUZ
Sheldon is the full time caretaker for a large property in the hills west of Temecula. The house is a 2 story 15,000 square foot home built about 20 years ago. It has many air conditioners distributed around the house and there is a large solar panel array to offset the cost of AC power. The owner of the home wants to reduce the use of the air conditioners due to the cost of maintaining them. The solution is to place 24 inch fans in 4 locations in the home.
Since there is excessive pollen each year the homeowner wants to avoid opening windows. So this installation will include filtered fresh air inlets next to each whole house fan location. The homeowner also wants the fans to be as silent as possible. Our belt driven blades rotate so slowly that they will not be audible outside the attic space.

TEMECULA
Bob Wells, owner of Wells Plumbing Heating and Air in Temecula, called to ask about a new whole house fan for his customer with a 2 story 2800 square foot home. He put in the first rafter mounted belt drive ever installed high in an attic. It has four 14 inch ducts connected to the 4 upstairs bedrooms. This was the first HERO program installation.

This was the first belt drive 30 inch ever installed in an attic.

Chris writes “I would like to get rid of my window AC units this summer. I live in a modest sized ranch. 1200 SF total. Thinking of putting fans in the 3 bedrooms and living room.” I replied “I see you were on my web site. By saying “putting fans in” do you mean putting my ducts in? You would do well with (not lista 3620 CFM with 3 ducts. It is a very fine infinitely variable direct drive fan at 18 inches. I can split the 18 inch duct into 3 12 inch ducts for the rooms. You don’t need a 4th in the living room since the bedroom openings will cool any room in the house.
