	Panasonic has designed a fan to meet the task of venting with the utmost in energy efficiency. The low sone (noise) level and low input wattage allow these fans to run continuously and quietly. This is not true of the typical ceiling fan which typically runs at 3 to 4 sones (one sone is roughly equal to the sound of a new refrigerator) while using considerably more electricity. This means that a 80 CFM (cubic feet/minute) fan can be hard-wired to run day and night and use less energy than a 60 watt light bulb left on for 7 hrs. Because this fan is quiet, rated for continuous use and a low-energy user, the Airetrack or Tork controls (see Ventilation Controls section) can be used to turn the Panasonic into more of a whole house fan. All fans come with a build in backdraft damper and white metal grill. Only the two speed model comes with a wall switch.The smaller standard depth ceiling fans, up to the 110 cfm, will not perform at their best if installed in a wall. The larger fans, along with the Whisperfit can be installed in either a wall or ceiling. All of the Panasonic fans can be used with a solid state speed control.

	Panasonic WhisperGreen
	WhisperGreen Panansonics are the latest concept in efficient fans. Because of their special design, the rated CFM level holds true no matter the duct length, number of elbows, etc. This makes the fan easier for the installer, because the installation in no way hinders the fan's performance. The VKS model features a built-in variable speed control which allows the fan to run continuously at a preset lower speed (30-80 CFM's). Turn on the switch, and the fan will run at its maximum speed of 80 CFM's. PE FV08VKS2 - - - $273.75 The VKM model has a built in motion sensor.

	Temperature gradients occur when there is minimal air movement within a room. Hot air generated either by the building's furnace or the heat of the sun typically rises to the ceiling . If the thermostat is set to maintain a comfortable temperature at the floor level, the temperature will typically rise between .5 and 1 degree per vertical foot as it heads towards the upper levels of the room. The Airius is designed to efficiently and silently move large quantities of hot ceiling air down to the floor level. The result is that within a very short period of time, floor and ceiling temperature are within a couple degrees of each other. Thus the downstairs will be warmer and the upstairs cooler, your HVAC system will run less and do more, and the interior space will be more comfortable and more productive. The Airius is easy to install, simple to maintain, and economical to operate. AIRIUS has models to accommodate ceiling heights from 8 - 60 feet, and 1000 -- 2500 sq. ft. The AIRIUS Thermal Equalizers operate on 110 VAC and 230 VAC (277 VAC versions are available) . The Airius will never win a beauty contest, but it certainly gets the job done. Typically used in commercial and retail applications, it is perfect for green houses and homes, especially homes with very high ceilings. Unlike blade fans that just move around the air, the Airius aerodynamically and imperceptibly forces a column of hotter air from the ceiling downward. Leave it running constantly, and lower your Heat & AC bill permanently! These models are 16� high, 13� diameter weigh 12 lbs and provide destratification for up to 1200 square feet.

	When summer heat builds up in the attic, it makes for a hot house. The solution; use night-time air to push heat out of the attic as well as the rest of your home. Open windows in the cool of the evening, turn on the HV, and let the cool air wash through the house, flow into the attic and exit through your pre-existing vents. Typical whole house fans are extremely noisy, use alot of electricity, are expensive to maintain, and leave a big, uninsulated hole in the attic floor. A better idea, the Tamarack HV whole house fan installs between the joists in the attic floor. The R-22 insulated doors open when the fan is in use, and close for a tight, low-profile seal when the fan is turned off. Use the Tamarack 1000(1000 CFM fan) for areas up to 2000 square feet. For homes up to 3000 square feet, use the Tamarack HV 1600 Gold. If the area to be ventilated is more that 3000 square feet, use a combination of fans. The Tamarack HV 1000 uses about the same amount of electricity as two 60-watt light bulbs. As long as there are at least 2 sq. ft. of vents in your attic, there is no need to cut further holes in the roof. The sound level of this fan is similiar to the hum of a refrigerator. Prices on all models include a white aluminum ceiling grill Note: This fan can be mounted vertically. Ask for the vertical mount grill if fan is to be mounted in this orientation.

	Need a whole house fan but have no attic, or a very small attic space? Use this amazing roof mounted whole house fan by QuietCool. It even works on mobile homes. This fan moves 1,479 cubic feet/minute, and replaces your home's warm stale air with clean fresh air 15 to 20 times per hour. It works just like a giant vacuum cleaner sucking out heat, odors. germs, etc. and replaces stale air with fresh outdoor air. How do you know which model to order? If your roof is flat or slightly sloped you will need either the flat roof or curbed roof model. Use the Curbed Roof model if there is a parapet or roof drain. Use the Flat Roof model if rain drains right over the edge of the roof. For an energy efficient and attractive termination in your ceiling, order the QC9 Ceiling Box and Damper Grill Kit. If there is 20 inches or more of space between the roof and the ceiling (even if there is no access to this space) you will need the ceiling box and damper grill kit and the QC-12005 insulated duct to bridge this gap and connect the fan to the ceiling grill. If there is less than the 20" space and the ceiling below is attached to the bottom of the rafters and the roof attached to the top of the rafters, this creates an enclosed duct, and you will need the QC8 kit. If the ceiling is connected to the roof using open web trusses, or if the roof is steeper than a 6/12 pitch, you can use our roof mount fans.

	The QuietCool PE QC-1500 fans are a multi-fan approach to whole house venting. The fans are unbelievably quiet because they attach and hang from your attic rafters, totally isolated from your living areas. The fans connect through insulated ducting, to the room below with an attractive square ceiling grill supplied with the unit. Because of this unique installation, they cause no vibrating of the attic floor directly over living spaces. They are rated at a super quiet .4 sones, a sone being the sound of a new refrigerator -so quiet, they are frequently installed with a vent into a bedroom! The louvers on the fan itself, are insulated to an R-4, and make a tight magnetic seal when the Quiet Cool is not in use. Just open up windows when the night air is cooler than inside air, and let your Quiet Cools pull this cool air through the house, and up into the attic to cool the attic. Pressure from the fans pushes this warm air out though your existing roof vents. The Quiet Cools can be controlled individually, or multiple fans can be wired to a single wall switch, timer, or remote control. With this flexibility, you can control when, where, and how much air flows through your home by simply turning on or off your individual Quiet Cool fans. With each fan using only 150 watts, the savings over air conditioning usage are huge. Here�s how to estimate approximately how many PE QC-1500�s you will need: One Story Home 1000 sq ft 2 fan system 1500 sq ft 2-3 fan system 2000 sq ft 3 fan system 2500 sq ft 3-4 fan system 3000 sq ft 3-5 fan system 4000 sq ft 4-6 fan system Two Story House 1000 sq ft 2 fan system 1500 sq ft 2-3 fan system 2000 sq ft 3 fan system 2500 sq ft 3-4 fan system 3000 sq ft 3-5 fan system 4000 sq ft 4-6 fan system To control this fan, use a standard on/off switch.

	At 4500 CFM�s (cubic feet of air moved/minute) each Quiet Giant is equal to three Quiet Cool Fans (see PE QC 1500). The unit is made up of two fans each connected to a 7� insulated duct. The two ducts join at a single 14� x 22� ceiling grill. Just like the Quiet Cool fans, the Quiet Giant is extremely quiet because it is hung from your attic rafters, instead of being mounted on the attic floor. The fan is rated at .6 sones, a sone being equivalent to the sound of a refrigerator turning on. Each motor has insulated, positive closing damper doors that prevent air flow between the attic and the home when the fans are not in use. Typically, the Quiet Giant is installed in a central hallway. The two fans can be turned on separately, providing 4534 CFM�s on high, and 2267 CFM�s on low speed. The Quiet Giant can be used in combination with the Quiet Cools, or with the Envirocool (see PE EC). Besides the cooling and energy savings benefits that you realize when you use whole house fans, they are also an excellent way to provide whole house ventilation. Even in the winter, the fan can be used briefly to exhaust stale indoor air, odors, germs, moisture, etc. Need more information?

Click on picture to view full-size image	Renewaire Energy Recovery Ventilator (ERV)
	The Mitsubishi core of this product is an engineered composite resin partition plate. Fresh incoming air is pulled into this core and preheated or precooled, depending on the season. An equal amount of stale room air is exhausted at the same time, creating a balanced system. As opposed to an HRV (Heat recovery ventilator)in winter, an ERV exchanges moisture as well as heat. The core works to prevent indoor humidity levels from becoming too dry or too humid by the partial transfer of water vapor. By the same method, summer outside air brought in for ventilation is reduced in temperature and humidity because its' heat and moisture are transferred to the exhaust air stream. The core on this system (unlike most other brands) stays frost free, requiring no antifreeze cycle. This mechanical simplicity means low maintenance and less energy usage. Using an ERV also allows you to install downsized furnace and air-conditioning systems. PE EV 70 - - - - - - $572.00 For homes up to 1500 square feet of living space.

Effective ventilation is insured with an integrated automatic proportional runtime control (the PT 24). Because it is a balanced ventilator, the Breeze simultaneously exhausts stale air and delivers an equal amount of fresh air back into the home. As with all ERV�s, this model uses free recovered energy to moderate the incoming air temperature and humidity from the extremes of outdoor weather conditions.

	Panasonic Spot/Whole House ERV
	All Panasonic ventilation fans combine energy efficiency and quiet operation. The new Panasonic WhisperComfort spot ERV fan series uses two ducts -- one to exhaust stale air and the other to supply fresh air from outside. Its low-rate, continuous run helps ensure that volatile organic compounds (VOCs) and other chemical and biological indoor air pollutants are vented out and replaced with fresh air. WhisperComfort technology provides a continuous, low-rate balance airflow to help improve indoor air quality. When air is brought in from the outside, the capillary core inside the WhisperComfort fan transfers heat and moisture to the supply air. This exchange both tempers the supply air coming in from outdoors and transfers moisture to maintain a comfortable indoor living environment. The American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) set a standard for whole house ventilation, requiring that continuous mechanical ventilation be 7.5 cubic feet per minute (CFM) per bedroom plus 1 CFM per 100 square feet. Panasonic WhisperComfort ERV fans are an affordable, efficient way to meet this ventilation standard. Since the WhisperComfort is a spot or larger area ERV, it can be installed in the ceiling of a single room or in common hallway, allowing for a whole-house ventilation system that meets the ASHRAE 62.2 standards to improve indoor air quality. WhisperComfort model number FV-04VE1 has two 2-speed setting options: 10/20 CFM or 20/40 CFM. The mechanical engineer or contractor will usually select the appropriate setting based on the size of the home and ASHRAE 62.2 guidelines. The default setting is 20/40 CFM and can be changed to lower 10/20 CFM prior to installation by repositioning a Molex plug accessible in the junction box from outside the housing. WhisperComfort operation can be designed two ways. For "Spot Ventilation" to meet CSA-F326; 10 CFM is suitable for a single bedroom, living room or family room, while 20 CFM is suitable for a master bedroom or large basement room. For "Whole House Ventilation" (IAQ) to meet ASHRAE 62.2; 20 CFM is suitable for 1 bedroom in a 500 square foot home, while 40 CFM is suitable for 2 bedrooms in a 1,750 square foot home. For living spaces with 3 or more bedrooms and greater than a 1,000 square foot home a second affordable WhisperComfort can be added. In addition, the WhisperComfort ERV fan features a frost prevention mode that automatically turns on when the outdoor temperature drops below 32 degrees Fahrenheit. During frost prevention mode, the WhisperComfort cycles between exchange air and exhaust only air to prevent core freezing. PE FV04VE1---$456.75

	The Fantech In-line fan is designed to be installed between sections of round duct. This remote installation insures a low sound level at the grill. Indoors, the fan is usually installed in the attic with ductwork leading to a bathroom ceiling grill from one end of the fan, and ductwork leading to an outdoor roof or sidewall vent coming from the opposite end. Because the housing is made of Noryl plastic, the fan can also be mounted in outdoor (above ground) and wet locations. In addition, the fan is sealed to prevent moisture from entering the housing and to prevent leakage if the fan is to be used for radon mitigation. With the use of a Y-connector, a single in-line fan can ventilate two areas. Sound absorbing accessories are available, but are necessary only for very short duct runs.

Click on picture to view full-size image	The Solar Powered Fan-Attic
	The Fan-Attic is a self contained unit that can be placed on the roof, and be fully operational within an hour. Installation consists of mounting the flashing over a 13" diameter hole cut through the roof sheathing. An 11-watt photovoltaic module integrated into the fan's cover generates continuous power supply to an efficient, low voltage fan motor. Because the fan uses no electricity (and doesn't require an electrician for installation) the unit pays for itself in a short time. The fan works slower in early morning and late afternoon hours. During the hottest part of the day, when the most circulation is needed, the solar panel produces its highest output.This allows the Fan-Attic to remove 600 to 800 cubic feet per minute (cfm's) of air. This stale air is replaced by fresh outdoor air drawn in through your pre-existing attic vents. One Fan-Attic will ventilate about 1200 square feet. For larger attics, place one Fan-Attic at each end. The Fan-Attic is made of ABS plastic with an alloy coated steel base and flashing. The base is mushroom shaped, so that water can not enter the unit, but hot stale air is vented out. PE FA - - - $371.25 Lead flashing A lead flashing is required if the unit is being installed on a tile roof, so that the base can conform to the roof surface. PE FAL - - - $63.70 The thermal snap switch is designed to turn on the attic fan when the temperature in the attic reaches approximately 80� F and off when the temperature goes back down to 70� F. This is a good option in climates where winter moisture build up in the attic is not as issue. Turning the fan off on colder days will prevent this cool air from conducting into your living space. It will also extend the life of the fan. PE FAS - - -$26.00
